CHAPTER VI.

The succeeding articles, viz.:

1. The Geology of Hamilton County; 2. Our subterranean water resources and well-boring; 3. The adjacent water-sheds in Ohio; 4. Kirkwood’s survey for a water supply--1865; 5. The Ohio River; 6. Scowden’s survey for a water supply--1872; 7. Moore’s survey for a water supply--1882;

have been prepared expressly for the dissemination of that information bearing upon the proposed new water supply, that will be useful, as well as interesting, to the citizens of Cincinnati at this particular time. These subjects have their respective bearing on our water supply,--that of the geological structure being especially important, because we learn from it a more accurate knowledge of our subterranean resources; of the impossibility of infiltration of the Ohio River waters, and of the formation and availability of our water-sheds.

The oldest rocks are designated by Eozoic system, consisting of Laurentian and Huronian groups, and are metamorphic rocks underlying a broad belt in Canada, from Labrador to the Lake of the Woods, and thence to the Arctic Sea. It is computed that this group of strata attains a thickness of 47,000 feet in Canada.

The Potsdam sandstone, the first member of the Silurian system, rests unconformably on the Eozoic rocks wherever the two are found in contact. This, as its name implies, is a sandstone, and is the first product of the invasion of the Eozoic continent by the ancient ocean, and the action of the shore waves upon the cliffs and surface.

It has been reached in the deep borings made at Columbus, Louisville, and St. Louis. Neither the Eozoic or Potsdam stones are exposed in any part of Ohio. Resting on the Potsdam stone, is a formation called calciferous sand-rock, so named in New York because there it consists of a mixture of lime and sand. This formation holds the lead of central and eastern Missouri.

Trenton limestone, with its underlying strata of chazy, Black River, and bird’s-eye limestones, rests on the calciferous sand-rock, and forms a calcareous mass of 300 to 600 feet in thickness. It is exposed in New York, Canada, Lake Superior, and Upper Mississippi, where one of its members, the Galena limestone, claims special notice as being the repository of all that rupture.

Upon the Trenton rests the Hudson group, consisting of the Hudson River and Utica slates, and composed of mixed calcareous and argillaceous sediments. This group is regarded as an equivalent to the blue limestones, or Cincinnati group, which are of special interest to the inhabitants of Ohio, inasmuch as they are the lowest rocks exposed within our territory.

These older rocks are brought to the surface by an axis of upheaval, reaching from Nashville to Lake Erie. They have been still further exposed by the cutting down of the valley of the Ohio, near Cincinnati, where 800 feet of the series are exposed to view. The wells on the upper Cumberland, in Kentucky, were sunk in rocks of the Hudson age. The earthy limestones of the Hudson period indicate a shallow and retreating sea, an approach to land conditions, and the completion of one circle of deposition.

The rocks next in order are:

The Oneida conglomerate marks a period of land subsidence, or water elevation. It is composed of coarse materials torn from the coast by shore waves. The system is found in central New York.

The Medina sandstone.--A period of mechanical sediments. In New York it is 300 to 400 feet in thickness. It has been struck in borings for oil in northern Ohio, but not well marked.

Clinton Group, in Ohio, is represented by a limestone 15 to 20 feet thick, an outcrop following the line of junction of the Lower and Upper Silurian.

Niagara Group is above the Clinton and occupies a wide-spread and more important formation, composed of equal masses of limestone and shale. This is the rock that underlies Chicago. The Niagara and Clinton overlie the Cincinnati Group.

Salina is the formation from which the salt is obtained at Syracuse. In northern Ohio it overlies the Niagara, and contains the gypsum of Sandusky. This deposition marks the era of a retiring sea, which left a series of shallow basins that became great evaporating pans.

Helderburg group is the surface rock of a large area in Ohio, and forms a summit of the Upper Silurian, and completes a circle of sedimentary formation corresponding, in a way, with that of the Lower Silurian.

The Trenton groups are nearly pure carbonate of lime, while those of the Niagara series--Clinton, Niagara, and Waterlime--are highly magnesian.

The Devonian age contains many strange forms of ancient life. In the Mississippi Valley, the Devonian strata are mostly calcareous, and much thinner than in New York and Pennsylvania, showing plainly that here, as in eastern Canada, open sea prevailed during this age, and that the Cincinnati Arch formed a land surface probably throughout all the Devonian ages. The Devonian system comprise:

Oriskany sandstones.

Corniferous limestone.--An open sea deposit. The average thickness in Ohio is 100 feet, and forms two belts of outcrop on opposite sides of the Cincinnati arch. The rock contains 20 per cent. of magnesia. Fragments of land plants and limbs of trees are found in this group.

Hamilton group.--A soft, blue limestone in Ohio.

Huron shale--exhibits a prevailing black color, and contains 10 per cent. of combustible matter. The line of its outcrop is marked by oil and gas springs. It is exposed in Kentucky and Tennessee, on both sides of Cincinnati anticlinal. It contains a large amount of carbon, derived from sea-weeds.

Erie shales is the name given to the Huron shale in northern Ohio and Lake Erie.

The carboniferous system is the highest group of rocks found in Ohio, and holds nearly all the beds of coal. As this period is not relative to Hamilton County, we shall only briefly refer to it.

At the period of the formation of the lowest bed of coal, the level of the carboniferous continent would seem to have been the highest; for when the stratum of bituminous matter had accumulated to the depth of a few feet, it was submerged by water, that brought shales and sandstone, and spread them in layers of many feet in thickness above it, before the requisite conditions were reached for the formation of another stratum. The intervals of repose, when the surface of the land was nearly at a level with the sea, were marked by the carbonaceous matter, and the thickness of each stratum measures the length of time during which this state of quiescence continued.

The changes of level were apparently all in one direction, that of submergence. During the epoch of the coal measure, the surface of the land and at the sea level, while the first stratum of coal was forming, was depressed until there had been deposited upon it a series of strata, which measured in Ohio, before being eroded, fully 2,000 feet in thickness, and included at least twelve workable seams of coal, with a great number of thinner ones.

At the time of the formation of the highest coal-beds, the Alleghany Mountain system was elevated, and an area including most of the States of our Union was raised above the ocean, never again, to the present time, submerged. The anthracite coal basins of Pennsylvania were once a part of the Alleghany coal-field, but were isolated by the upheaval and erosion of the mountain ridges; and by this disturbance, all the rocks were more or less metamorphosed, and most of the volatile ingredients of the coal driven off, leaving it in the condition of anthracite.

THE DEPOSITS OF DRIFT.

The period immediately following the Tertiary age [but separated from it by we know not how many years] presents a complete change in the physical condition, that during this time the pervading warmth of the Tertiary was changed to an Arctic cold. While, in the former age, the climate of our Southern States was carried to Greenland; in the latter, or drift period, the present Greenland was brought as far south as the Ohio. This was when we had our icebergs or glacial age. The gravel, the bowlders, and an unstratified clay thickly studded with small fragments of rock, are the glacial surface-covering. Mingled with these are found many pebbles and bowlders of crystalline rock, such as are found north of the great lakes.

The finding of large bowlders in fields are the deposit of icebergs that once floated over our country. The glaziers reached as far as Cincinnati, planing, grinding down, smoothing all rock surfaces, and excavating the basins of our great lakes. The retreat of the glaciers left clay and bowlders and a great inland sea of fresh water, filling basins, before occupied by ice, 500 feet above the present surface of Lake Erie. At a later period, by continental elevation or the removal of barriers to drainage, the water level was gradually depressed until the inland sea was reduced to the comparative insignificance of our great lakes.

The descent of the water by motion of the waves, cut the well-marked terraces and edges.

CINCINNATI ANTICLINAL.

The term, Cincinnati Group, is now applied to the blue limestone series, and is an equivalent, in the geological nomenclature, to the Hudson Group of New York.

Its thickness is estimated at 1,000 feet. The line of upheaval passes from the south line of Tennessee, with a direction a little east of north, through Cincinnati to Lake Erie. Throughout its whole length the strata are raised in a distinct arch, from which they dip away, on the one side under the Alleghany coal-field, on the other beneath the coal basin of Indiana and Illinois.

The bearing of this axis of elevation is nearly parallel with that of the folds of the Alleghanies; that the date of its upheaval was subsequent to the carboniferous, and anterior to the Triassic period. The line, north of Cincinnati, extends from the Ohio River in a direction a little east of north to the lake shore, between Sandusky and Toledo. In consequence of the erosion, which all the region bordering the Cincinnati Arch has suffered, the line of the axis presents no conspicuous topographical features. About Cincinnati the summit of the arch has been much more deeply and extensively removed than farther north, yet this is still higher than its northern prolongation.

There is every reason to believe, therefore, that this was originally the highest part of that portion of the arch within Ohio, and, in common with the Blue Grass district of Kentucky, the blue limestone area about Cincinnati is the most elevated portion of the ridge; that which has been the longest above the sea level and suffered most from surface erosion. We find here a line or tract from which the strata dipped on both sides in opposite directions.

The strata, that are found in the tops of the Cincinnati hills, can be followed to the eastern side of Brown County, where they seem to disappear beneath the river with a marked easterly dip; while below Cincinnati, near Madison, Indiana, the same beds are carried beneath the river by a strong westerly dip. The Cincinnati anticlinal, unlike the folds of the Appalachian system, generally has its longer slope to the westward, and its steeper descent towards the east, estimated at 35 feet per mile. In the western half of the State, and especially along the summit of the Cincinnati Arch, the dip of the strata is strongly northward, amounting to about 1,000 feet between the Ohio and the lake. The surface of the Cincinnati Group is in Highland County, about 500 feet above Lake Erie, while on the lake shore it is nearly 400 feet below the lake. These figures do not represent the entire dip, inasmuch as the crown of the arch is extensively eroded where it crosses the Ohio in Clermont County. The Cincinnati section was originally crowned, there is little reason to doubt, with the Lebanon beds [the highest rocks of the Cincinnati group] in whole or in part, which suffered by erosion, forming our valleys of to-day.

The surface of the blue limestone, near Lebanon, is 441 feet above Lake Erie, while the same rocks were found in the Columbus well to be 721 feet below Lake Erie, a dip of 1,167 feet in a distance of about 70 miles by an air line, or 16.6 feet per mile.

Toward the northern extremity of the arch the dip is north-west and more rapid, the strata descending under the Michigan coal-field. Near the lake-shore the minimum dip is 20 feet to the mile, while on the Ohio it is 40 feet. The easterly dip is a succession of steps or waves beneath the trough of the Alleghany coal-field, the axis of which passes near or beyond our eastern border. This dip is so great that the lowest stratum exposed on the crown of the Cincinnati arch is on the eastern side of the State, buried about 2,000 feet beneath the surface. East of the Ohio all the rocks rise again, and not only the lowest exposed in our State, but even those which underlie them, crop out on the flanks and summits of the Alleghany Mountains. Along the Kentucky River from Frankfort to Nicholasville, and at Murfreesboro, Tennessee, the basal portion of the blue limestone series is exposed to view; and if it was originally as thick at these points as elsewhere, not less than 800 to 1,000 feet of the upper part have been removed.

HAMILTON COUNTY.

Strictly speaking there are no hills in Hamilton County, the surface being all referable to the tablelands and to the valleys worn in them. The elevated lands, called hills, are merely isolated remnants of the old plateau, which have, thus far, escaped the long continued inundation. This isolation is effected by the Little Miami, the Ohio, the Millcreek Valleys, and the abandoned channel of the Great Miami.

The bedded rocks of the Cincinnati section are as follows:

Lebanon beds, 293 feet { Hill quarry beds, 125 feet Cincinnati beds proper, 425 feet--{ Eden shales, 250 feet Mt. Pleasant beds, 50 feet { River quarry, 50 feet --- Total, 768 feet

The Mt. Pleasant beds are so named because, at the Ohio River bed at this point, they are the lowest of the exposed beds, and underlie the lowest beds at Cincinnati by 50 feet. The Cincinnati beds have their inferior limit at low water of the Ohio, and for an upper boundary the highest stratum found in the Cincinnati hills. Their greatest elevation, above low water-mark, is 450 feet. The Eden, or middle shale, is so named because of its prominence in Eden Park hills. It has no economical value, indeed its relation to economical interests are mainly in the way of disadvantages to be overcome, because of its instable character. Of the 250 feet not more than one foot in ten is limestone, the remainder being shales, clay, or soapstones. These shales have scarcely tenacity enough to hold their place in steep descents, still less, when they have been removed from their original beds, can they be made to cohere, and they form treacherous foundations for buildings erected, or for roadways constructed upon them.

The strata of river quarry-beds are comparatively but little exposed. A moderate amount of building-stone of superior quality is taken from the Covington quarries. But little can be burned into lime, but the concretions constitute a hydraulic lime of great energy.

The Lebanon beds, in contrast to the Mt. Pleasant beds, are the highest of the Cincinnati group, and the location determine their name.

The drift formations are divided into--

1. Drift deposits of the highlands and slopes.

2. Drift deposits of the lowlands and valley drift-beds.

The upland drift has no uniformity in the order of formations aside from the monotonous deposits of yellow clay, which, when filled with water, becomes quicksand. But little clean gravel occurs in the upland, and bowlders also are unfrequent. The drift clays come largely from the waste of blue limestone effected by glacial attrition, while the natural soil has the same origin, except the work of disintegration has been done by the slow action of the atmosphere.

The lowland drift consists of the following terraces, in a descending order:

FEET. Soil 2 to 5 Gravel and sand with seams of loam, 40 to 60 Brick clay with sand and loam, 20 to 30 Buried soil with trees, leaves, etc., 5 to 10 Gravel and clay, 5 to 10 -- --- Total, 72 115

The gravel of the Ohio differs from the Miami in being largely composed of sandstone pebbles instead of limestone.

A formation of local occurrences, known as the blue or Springfield clay, is found in a few places, but in limited, vertical and horizontal, extent. The greatest thickness, of more than 30 feet, is found on north Pearl Street, above Pike.

The broad valley, now occupied in part by Millcreek, extending from the present valley of the Great Miami at Hamilton to the Clifton hills, just north of Cincinnati, separates into two branches, one passing to the north and east of the city, and entering the valley of the Little Miami between Red Bank station and Plainville, while the other branch is the present valley of the Millcreek. There are no rocky barriers (nothing, in fact, but the same drift terraces that make the walls of its present course) to shut out the Great Miami from entering the Ohio valley at the same points where the Little Miami and Millcreek enter. There is every reason to believe that this was once its course.

Another of the earlier courses of the Great Miami, is now occupied by the Dry Fork of the White Water; still a third of the old channels is found near Cleves, Miami Township, where the Miami approaches within one-half mile of the Ohio, but is blocked from entering it by a ridge 150 to 175 feet, composed of glacial drift, and instead makes a circuitous route of 10 miles for an outlet.

The well of Timothy Kirby, in Cumminsville, developed the following borings:

FEET. Soil and brick clay, 12 Sand, 4 Blue clay with gravel, 30 Gravel, 19 Coarse sand, 3 Sand, with fragments of bituminous coal, 11 Blue clay with gravel. (Low water of Ohio River.) 9 Blue clay--fine sand, sprinkled with coal, 16 Sand, water-worn gravel, blue clay, with occasional fragments of bituminous clay. Shales of blue limestone group, 43 --- Total, 151

A remarkable feature of the Millcreek is here presented, of the present bed being at a higher level by 120 feet, than that of the ancient channel,--an erosion that could not have been effected under existing circumstances, but more probable, to the glacial period.

The coal-field wastes are also unaccountable.

OUR SUBTERRANEAN WATER RESOURCES.

Underlying our drift formation is that impervious strata of blue limestone, 1,000 feet in thickness, through which no water can circulate. The lowest limit of this mass of stone is at low water of the Ohio River, at Cincinnati, from which point it anticlines in all directions. There are crevices or pockets, however, in which water has been accidentally found. The following are examples:

===================+==============+=====================+======+ | | | | NAME OF OWNER. | LOCATION. | FORMATION. | DEPTH| | | | IN | | | | FEET.| -------------------+--------------+---------------------+------+ John Kaufman. |Vine Street. |Blue clay. | 25 | | |Sand and quicksand. | 73 | | |Blue clay. | 55 | | |Quicksand and gravel.| 35 | | |Limestone. | 25 | | | | | | |Soil and quicksand. | 75 | Holder’s Tannery. |Colerain Pike.|Clay. | 90 | | |Limestone. | 50 | | | | | | |Alluvial and gravel. | 80 | Freiburg & Workum. |Main Street. |Limestone. | 170 | ===================+==============+=====================+======+

The waters of the above wells are necessarily hard, although that at Holder’s tannery is used for all purposes. The water at John Kaufman’s is very turbid. The Freiburg & Workum well was originally a dug one, forty feet deep, but the quantity was insufficient. When they struck the present source, they destroyed the adjoining surface wells of Hoffheimer Bros.

A number of failures to secure water in this limestone formation is on record, but we can notice only a few.

At Rasche Bros., tannery, on Plum Street, opposite Bank Street, they drove a 6 inch well through, respectively, 16 feet of clay, 4 feet quicksand, 15 feet blue clay, 70 feet yellow clay, and solid quarry rock. A pump was then inserted but was inoperative on account of the large amount of sand. They continued the boring to 185 feet, striking clay and soapstone, but found no water, and abandoned the undertaking.

Wm. Kirkup & Son, Pearl and Ludlow, bored 60 feet into rock, for water, without success. At Maddox, Hobart & Co.’s rectifying establishment, they have pierced the rock 150 feet, but found no water up to this date. At Weber’s brewery, on McMicken Avenue, an attempt was made to get water in the rock, and abandoned, after boring to a depth of 458 feet.

The Cincinnati group is about 1,000 feet in thickness of blue limestone, forming, almost exclusively, the rocks of Hamilton County, although an outcrop of the oil stratum has been struck in the wells of the Cincinnati Coffin Company and White Mills Distillery. At the former establishment, flowing gas was found at a depth of 82 feet. Another well was started, and at the same depth gas was discovered. The boring of the latter was then continued into the rock to the depth of 168 feet, when water was found. The water was analyzed by Prof. Wayne with the following result:

GRAINS IN EACH GALLON.

Chloride of Sodium 33.21 Chloride of Calcium 4.20 Chloride of Magnesia 1.17 Sulphate of Lime 10.64 Carbonate of Lime 26.64 Carbonate of Magnesia 3.15 Oxide of Iron 12

The gas burnt out in a few days.

White Mills Distillery has four wells, from 4 to 6 inches in diameter, and 220 to 235 feet in depth, bored through, respectively, 50 feet of clay, 40 feet clay and quicksand, and balance _soapstone_ or shale and limestone, where water was found in a crevice, highly charged with gas and very brackish.

The following wells secure their water from drift terraces:

Upon the limestone lays the drift, consisting of water-worn pebbles, gravel, sand, and clay. The porous nature of this formation, with the assistance of a level surface plain, absorbs a very large percentage of the rain-fall, and produces a fertile subterranean water supply, whose depth varies from 30 to 200 feet.

There are in this vicinity about 250 wells that secure the water from this source. The water is strongly impregnated with iron and magnesia--a ferruginous decomposition from the fossil drift-wood found in this formation. The availability of these wells is in proportion to the capacity of the respective pumps attached to them, but their combined requirements have had no apparent effect, at present, on the source. Yet the fact can not be disputed, that this drift supply of water is a very limited one.

The practical experience in London and Liverpool substantiate the above fact, for there the underground sources have been materially lessened by the demands made upon them, notwithstanding they are the richest resources of this nature, and vastly superior to ours.

Prof. Orton, of the Ohio Agricultural College, in a valuable paper on the “Relations of Geology to the Water Supply of the Country,” refers to the purity of the drift water in the south-western part of the State. He says: “The broad and fertile terraces of the river valleys constitute, especially in the south-western corner of the State (Ohio), the most attractive and most valuable portion of its area. They consist of sand and gravel in large measures, and to this structure they owe their chief attraction. _But this same structure renders them unfit to be used for the water supply of the towns built upon them_; for, although an abundance of clear and sparkling water can easily be reached, it must not only be looked upon with suspicion, but must be positively condemned as unsafe.

“These gravel-beds are as porous as a sieve, and there is indisputable proof of the free communication of the water sheet and all the receptacles of impurity that the surface of the ground contains. The only relief is found in the fact that the water sheet is also in free communication with the rivers, rising and falling with them; _but_ even _this_ does not free the wells from the poisonous effects of the filth soakage from above. Geology turns over to sanitary science the conclusion, that the drift wells of central and south-western Ohio are, in all densely populated districts, small cities, towns, villages, and hamlets--even in those containing no more than a dozen houses--_utterly unfit for human use_.”

The above facts are applicable to all the drift formation, including that portion protected from immediate filth soakage of blue clay formation.

A recent examination of our sewerage system, by the U. S. Census Bureau, developed the fact that Cincinnati is polluting its subterraneous soil, to an alarming degree, by the vault system. That no city has so neglected the sanitary necessity of tapping the sewers for house drainage than Cincinnati; that this nature of carelessness was the cause of Memphis’ sad fate, which we have escaped because our soil is of sand and gravel, and susceptible of natural drainage. Yet through this same soil passes the water that is used by some 250 well-owners, still the use of this water is increasing.

London was originally supplied by shallow wells in gravel-beds of 10 to 20 feet in depth, and the direction of its growth was controlled by this water-bearing strata, until the establishment of the New River Water Company in 1600. The Public Health Act of 1872 gives the sanitary authorities power to close these wells.

ARTESIAN WELLS.

Beneath the Cincinnati group are the calciferous sand-rock and Potsdam sandstone, which are porous and water bearing, but they rise to the surface nowhere in our State. They have been reached, however, at this point in several of the deep well-borings, and flowing water of sulpho-saline nature was found, at the following locations:

The synopsis of boring is condensed as follows:

July 24, 1880.--The contractor, John J. Pfeffer, drove a 6-inch iron tube with a heavy sinker, a few feet at a time, through 123 feet of drift, into limestone. A sand-pump was used to remove the loose formation. This portion was completed August 2d, 11 A. M.

August 2.--Commenced drilling a 4½-inch hole through the stone formation at an average rate of 33 feet per 24 hours, and continued to a depth of 425 feet, when the diameter of the hole was reduced to 4⅜ inches. The drilling was then continued, at the rate of 29 feet per 24 hours, until the 28th of August, when the socket pulled out of pole attached to sinker at bottom of well, and at the same moment the top pole, attached to chain on drilling beam, broke and fell into the well along-side of the sinker. This accident was repaired September 7th, and drilling resumed, at rate of 20 feet per 24 hours, until a depth of 1,025 feet was reached, October 11, 1880, when the drill broke. Resumed work, at rate of 12 feet per 24 hours, until November 5, 1880, when a depth of 1,265 feet was reached. At the depth of 1,225 feet, the well was tested by sinking a 4-inch pipe into the well with a bag at lower end to fit tightly into the 4½-inch bore. When the pipe reached a depth of 15 feet below the 6-inch tubing, the water flowed over the top of the pipe at surface, showing a leak around the bottom of the pipe where it was bedded in the rock.

November 8th.--Tested well, and found a pressure of 30 lbs. per square inch, and a flow of 90 gallons of water per minute.

February 17, 1881.--When testing well No. 2, the gauge was placed on this one, which showed only 15 lbs. The bore was then increased to 4½ inches, and drilling continued to a depth of 1,360 feet, the last 40 feet being only 3½ inches in diameter. The additional 125 feet was through alternate formations of sand and limestone; the last 10 feet through a hard flinty formation. Boring into this last formation increased the pressure to 41 lbs., and the flow to 200,000 gallons per day. The outlay of the two wells is placed at $8,000.

The analysis of the Moerlein artesian well, by Prof. Wayne, gave the following results:

Prof. Newberry is of the opinion that soft water is improbable in these deep rocks.

WATER-SHED.

The courses of our streams show at a glance that a water-shed crosses the State from north-east to south-west. This water-shed forms a range of highlands that slope by long and easy descent to the Ohio in the south, more rapidly to the lake in the north. _This water-shed in its relief is almost insignificant_, its average altitude being only 500 feet above the lake, its highest point rising perhaps 1,000 feet above the bottom valley of the Ohio. Our topographical features may therefore be described of a plain, slightly raised along a line traversing it from north-east to south-west.

The following altitudes will show the topography of the northern divide. The levels are all above Lake Erie:

The actual crest of the divide forms a singularly tortuous line with remarkable variations of altitude. The water-sheds, with which we are particularly interested, are found in the counties of Shelby, Mercer, and Auglaize, where we have the water-gap of the head-waters of the St. Marys and Auglaize, as feeders of the Maumee River with the Wabash and Big Beaver Rivers on one side, and the Great Miami on this side; with another gap, between the Miami and Mad Rivers, and the Scioto River, found in Logan and Hardin Counties, in which the highest points of the State are found viz., 1,000 feet above low water in the Ohio River. These streams descend very rapidly to the level plateau (500 feet above the Ohio River) passing over lime and magnesia rocks, through swampy lands and “cat-head prairies,” the latter composed largely of vegetable accumulations. The population, through which the Great Miami and Mad rivers flow, is approximately 360,000.

The available resources of the Big Beaver, Wabash, and St. Mary’s water-sheds are collected in St. Mary’s Reservoir, a lake of 47,000 acres, for feeding the Miami Canal north; while Lake Laramie in Shelby County, and Lewistown Reservoir in Logan County gather the waters of the Miami, and being at the summit level, feed the canal both north and south. This level is 519 feet above low water in Ohio River, St. Mary’s 424 feet, Eden Park Reservoir at Cincinnati 235 feet, and Third Street Reservoir 173 feet. The distance in air line from Cincinnati to St. Mary’s is about 95 miles, to Lewistown over 100 miles.

The waters of all the streams named present those features that experience considers most objectionable for a gravity supply, namely:

“1st. In the calcareous nature of the soil, producing hardness of water.

“2d. In the low and level plateau of water-sheds from which a minimum surface flow can be realized, requiring storage reservoirs of large surface area, that are objectionable, because; 1. The loss of water by evaporation: and 2. The liability to stagnation of water and propagation of vegetation.

“3d. The streams are fed by the drainage from richly manured farms, and the water polluted by vegetation of the swampy lands, and the sewage of a large and growing population. This condition is intensified, when we consider the proportional size of the streams to the amount of pollution, and the fact that the most perfect means of filtration would not suffice to make the water wholesome.

“4th. The available resources of these water-sheds are now used for feeding the Miami Canal, from which a number of mill-owners secure their power, whose rights must be protected.

“5th. The insufficient elevation of the sources for securing a fair hydrostatic water pressure, and their extreme distance, causing loss of head by long conduit, and enormous cost for construction, for conveying unwholesome water.”

RIPARIAN RIGHTS.

The compensation to millers by the Manchester and Liverpool Water-Works was fixed by Parliament at one third of the available rain-fall. Nearly one-half of the present capacity of the Glasgow supply is used by mill-owners.

On this subject John W. Erwin, resident engineer of the Ohio State Board of Public Works, says:

“The riparian right of water-users are great, and could not be purchased for $2,000,000. The water for this purpose can not be spared. The canal is fed as far as Middletown, by a feeder from Mad River. At Middletown we feed it from the Miami, which furnishes its supply of water to Cincinnati, a distance of forty-four miles. The Middletown Hydraulic Company have owned their rights since 1808, long before the canal was constructed; and when the canal was built there was no surrender of such right, merely common consent to the use of the water, but since that time more than double the amount of water is used than was contemplated.

“By taking water to Cincinnati from the river, you injure the power supplied by the river at all points between Middletown and Cincinnati, and you would find great objections raised by users of power along the canal. The power derived from the canal is the life-blood of the town of Middletown, and of the mills along its banks--at Excello, Woodsdale, Rockdale, Hamilton, Rialto, Port Union, Crescentville, Lockland, and other places. The mills have large interests, and would not surrender their rights without a struggle.

“A large portion of the water of the Miami, and at the present time we might say half the volume of the water of the river is carried into Cincinnati by the canal. This is more than was ever contemplated, and is destined to injure the water-power of the river itself.”

The abandonment of the canal in the city, will no doubt be accomplished within a short time, when provisions should be made to provide a better use for this surplus water than turning it into Millcreek.

Monthly and annual quantity of water from rain and snow reduced to water, in inches and hundredths, at Cincinnati, Ohio. Latitude 39° 6′ north, longitude 84° 29′ west.

KIRKWOOD’S SURVEY.

In 1865 the common council appointed a special commission to investigate and report upon the best method of obtaining an abundant supply of pure and wholesome water. The committee consisted of L. A. Harris, mayor; Thos. H. Weasner, president of council; D. T. Woodrow, Henry Pearce, and Henry Kessler, trustees of water-works, Geo. F. Davis, Wm. P. Wiltsee, and Chas. Brown, who succeeded R. B. Moore, members of council; and A. W. Gilbert, city engineer. They secured the services of the most eminent of engineers, John P. Kirkwood, of New York. His instructions were to ascertain the most economical and practical mode of supplying pure water, either from the gathering grounds by gravity, or by pumping from the Ohio River. No scheme was to be considered that would not provide at least thirty millions daily, with resources for future necessities. This limitation rejected Lick Run and Ross Run entering Millcreek; West Fork and East Branch of Millcreek, Duck Creek and Sycamore Creek entering Little Miami River. Those that presented _fair_ prospects for the collection of water as regards quantity were:

The objections to these waters were: 1. The hardness; 2. The contamination of richly manured farms; 3. The uncertainty of the availability of the water-sheds. To produce the thirty millions it required the combined area of Clear and Gregory creeks, besides large storage reservoirs for dry seasons. The distance of latter creek is 38 miles from the city, and 15 feet below flow-line of Eden Reservoir.

He considered the waters of the Ohio most preferable _providing the water was taken above the city limits_. The plan embraced a pumping service with two lifts, to be located in Pendleton, with storage and settling reservoirs and filter-beds. The elevation of reservoir was 200 feet above low water, and would not supply elevations above 175 feet. The estimates were:

Three settling reservoirs, $381,436.02 Two filter-beds, 514,220.50 Storage reservoir of 39 acres, 635,386.50 Pumping house and foundations for low service works, 194,822.80 Pumping house and foundations for high service works, 77,285.75 Pumping engines--two for low service and two for high service, 30 millions capacity, 402,500.00 Force-main, with river inlets, 119,979.50 Forty-two-inch supply main to Third Street Reservoir, 457,355.00 Lands and damages, etc., 105,225.00 Auxiliary pumping engine and reservoir for Walnut Hills, 150,000.00 ------------- Total, $3,038,214.07

The majority of the committee in recommending the plan stated; “that they regarded the question, as to the source of supply, as definitely settled for all time, that the Ohio River is the only means from whence this city should derive her supply of water. The site is as high up the river as can well be obtained without crossing the Little Miami.” This latter consideration they thought would be demanded fifty or one hundred years hence. The minority report recommended the retaining of the present system, and the construction of a new reservoir in Eden Park,--the minority report was adopted. Had the Eden Reservoir been completed within a reasonable period it would have served the purpose intended, at least for a few years, but before it was ready for use the consumption of water increased from five, to seventeen millions daily.

OHIO RIVER.

The Ohio River above Cincinnati has a water-shed area, estimated by U. S. Census Bureau, of 100,000 square miles, one-tenth of which is of limestone formation. The hardness of the water varies in proportion to the contribution from this formation. The water, at the mouth of the Big Sandy, is .8 of a degree hardness; at Markley Farm, 4½ to 8; at Dayton sand-beach, 7 to 8; at pump-works, 6 to 8; Eden reservoir, 7 to 9; Eggleston Avenue sewer, 7 to 13; wells in the banks of the river at Dayton sand-beach, 32 to 39; and those at Sedamsville 50 to 60 degrees. The well water is upland surface water. In fact, all borings in the banks of the river secure, in more or less degree, this nature of water.

In the south-western part of this State, the river flows over the bedded rocks of the Cincinnati group, its waters alternately impinging on one side of its banks, and depositing its earthy matters, through the influence of sluggish currents and eddies, on the opposite side, and forming what might be termed accidental beds, as in the case of the Dayton sand-beach. The material deposited is an argillaceous substance; and, with the friction and influence of the water, is partly transformed into quicksand. The beds do not form a part of the river in low water, as depicted by the sketch in the last report of the Board of Health.

The sediment in the Mississippi water, at St. Louis, is nearly two per cent. of the bulk of the water; the largest portion (944 in 1,000) depositing itself within 24 hours. The Ohio River water, at this point, is, at times, almost as bad. The sediment forms a tenacious and impervious clay, so susceptible of solidification that conductors of river water are only kept open by a constant flow of water.

The volume of water passing down the Ohio River is an extremely variable one. No special gauging, however, has ever been made to ascertain the quality; but from the surface velocities, measured by the Chief Engineer of the Southern Railway, we can approximately arrive at the figures

At 3-foot stage, by Water-Works mark, the velocity was .97 miles per hour. “ 6 “ “ “ “ “ “ “ “ “ 1.125 “ “ “ “ 18 “ “ “ “ “ “ “ “ “ 3.51 “ “ “ “ 21 “ “ “ “ “ “ “ “ “ 3.20 “ “ “ “ 27 “ “ “ “ “ “ “ “ “ 4.70 “ “ “ “ 31 “ “ “ “ “ “ “ “ “ 4.30 “ “ “ “ 41 “ “ “ “ “ “ “ “ “ 5.002 “ “ “

The slope of water surface, from water-works to bridge, was .367 of a foot for low stage; for average stage, .403 of a foot; and .415 of a foot per mile for high stage. The approximate flow of water in cubic feet per second at the Southern Railway Bridge is 5,000 feet for minimum stage, 100,000 feet for mean stage, and 400,000 for maximum stage. The minimum flow of the Schuylkill is 378 cubic feet per second; the Delaware, 2,000 cubic feet; the Merrimack, 2,100 cubic feet; and the Thames River, 700 cubic feet.

Investigations of the influence on our climate, by the removal of the forests, develop the fact that streams, utilized for water-power, have become less constant in their flow than formerly. The Ohio River has of late years exhibited greater fluctuations of levels than ever known, and has lost its prestige as a reliable channel of navigation. Prof. Newburg, in Vol. I of the Geological Survey of Ohio, records an instant where a large rock, at Smith’s Ferry, has recently become so fully exposed that on its surface inscriptions were found, that are ascribed to a race which once populated this country anterior to the nomadic Indians.

There are about 78 villages and towns and 13 cities on the Ohio River between Cincinnati and Pittsburgh, a distance of 460 miles. The population on this portion of the river, and its contributing streams, is over 3½ millions. The average population, per square mile of drainage area, on the Ohio River is 47; above Cincinnati, 35; on the Great Miami, 109; on the Delaware, 176; on the Hudson, 172; on the Merrimack, 92½; on the Susquehanna, 62; on the Connecticut, 78; on the Potomac, 54; on the Schuylkill, 45; on the Thames, above water-works, 300.

Considerable space has been devoted to River Pollution, to which attention is directed. The following remarks, however, afford comparative results for the Ohio River.

The comparative merits of river waters, as expressed in analytic results of pounds of sewage in each million gallons, are, for the Ohio water at Dayton sand-beach, .82; at Markley Farm, 1.00; at the pumping works, 1.81; at Eden reservoir, 1.78; at Eggleston Avenue sewer, 4.41; the Croton water, New York, .98; Glasgow, Scotland, water, .65; Thames River, 4.91; London supply, 1.33; Fresh pond, Cambridge, Massachusetts, 1.50; Mystic River, Boston, 1.87; Schuylkill River, Philadelphia, 1.58; Merrimack, above Lowell, .93; above Lawrence, .90; below Lawrence, 1.03.

The Thames and Lea Rivers have been condemned by the Rivers Pollution Commission because, as they say, there is no hope of remedying their disgusting condition, notwithstanding the parliamentary laws for their protection against pollution.

The Schuylkill River is the principal source of supply for Philadelphia, but its water is very suspicious. Above Reading, it is unfit for manufacturing and culinary purposes, owing to the large amount of sulphuric acid. This acid is, however, neutralized and considerably reduced before the water reaches Philadelphia. The Fairmount pool is polluted by cess-pool and slaughter-house drainage. The following means to restore and maintain the purity of the Schuylkill water has been suggested by Dr. Cresson:

1. The diversion of all sewage, now flowing into the pool of Fairmount dam, into another channel.

2. The diversion of all sewage, containing fœcal and animal matter, flowing into the river below Flat Rock.

3. The filtration of the sewage from all mills, to exclude solid matter, animal or vegetable.

4. The exclusion of ammonia waste and surface wash from gas-works, cemeteries, etc.

5. The cultivation of fish and of suitable plant life in and upon the waters of the river.

6. The erection of suitable cascades over the reservoirs, so as to secure the benefits of aeration to as great extent as possible.

7. The employment of proper prophylactic and curative agents as occasion may require.

Boston obtained legislative power to protect Pegan Brook from sewage pollution. Test cases, to compel manufacturers to provide some other means of disposing of their drainage, were carried to the Supreme Court, and decided in favor of the city. Similar cases will be brought against other offenders. In the meantime the pollution continues. The same authorities procured a law to protect Mystic Lake, and provide other channels for sewage. The provisions of the act were held to be impracticable, and the law is now a dead letter.

The self-purification of river water is not recognized by some authorities, but equally good authorities value its merits. The following observations on this subject are particularly applicable to Cincinnati:

“The most efficacious means to get rid of the sewage is not to put it into the river at all.

“A chemist can tell you the amount of organic matter contained in the water, but that covers an infinite variety of matters. He has no means of discrimination as to what is really the ferment--the infectious material--of cholera from a great number of other organic matters.

“The question is, not whether the chemist would find out the organic matter, so much as it is, whether the germs that disseminate the disease still have their property further down the river. This can only be solved by the effects. _You might go on using the water for years, and it might not be discovered until some outbreak of disease occurs directly attributable to the water._”

The practical sanitary experiment would then be solved, but at the expense of a number of lives.

Dr. Klob, of Vienna, has discovered, in the evacuations of cholera patients, millions and millions of microscopic fungi similar in form to a mushroom.

There are, above the Cincinnati pumping works, six sewers discharging their filth into the Ohio River, besides the fœcal drainage of no less than five thousand privies, all within a radius of less than three miles. Now, the quality of such water is readily established, for we are putting the sewage into the water knowing there are no means to get rid of it.

A recent examination of the currents of the river passing the inlets was conclusive that the Eggleston Avenue sewer, 1,000 feet below, could have no effect on our water supply. Be this as it may, its proximity taxes our delicate tastes. The location of the inlet of the Shield aqueduct is not a desirable one, being at the revetment wall, past which all the shore water flows. The small aqueduct certainly can not be improved, its inlet being sixty feet beyond the wall, where the currents produce the best water obtainable.

The value of changing the location of the intakes can be illustrated to a good advantage by the experience of London during the cholera epidemic of 1854. After the epidemic of 1849, the Lambeth Water Company moved their intakes to Teddington, beyond the range of London sewage; while their competitor, the Southwark Company, continued to take its water close to one of the sewers. Their respective water-pipes interlaced each other; and of the 26,000 houses supplied by the Lambeth Company, there were only 294 deaths in 1854, while in 40,000 houses, supplied by the other company, there were 2,284 deaths.

SCOWDEN’S SURVEY OF MARKLEY FARM.

On the 29th of April, 1871, the Trustees of Water-Works, in response to the Council, submitted a report to them upon the necessity of a new water supply. On the ensuing 9th of June, the Council ordered that a competent engineer be employed to examine sites, and report upon the most suitable location for water-works, with plans, estimates of cost, etc. Mr. T. R. Scowden was accordingly appointed; and, on the 9th of September of the same year, he submitted a supplemental report, recommending, in the highest terms, the “Markley Farm” site. Upon his recommendation, the property was purchased for the sum of $22,321.50, consisting of 146 acres, with a river frontage of 2,000 feet. The principal points upon which the recommendation was based were:

“The site known as Markley Farm is a point where the water of the Ohio River is deep and free from drainage or any other vitiating influence to affect its quality, perhaps for a century to come, if ever. The shore is bold, and, with the bed of the river, is of gravel and rock formation, washed clean by an active current at all seasons of the year. Pumping works may be located at this point without any objectionable and expensive inlet-pipe; while the adjacent hills afford an excellent site for a storage reservoir, 307 feet above extreme low water, and 75 feet above the Garden of Eden Reservoir. On the lower level there is a fine plateau for locating, not only the pumping house, but subsiding reservoirs and filtering basins.

“The force-main extending from the pump house to the storage reservoir will be short, or about 1,450 feet long, whereas, works located on the second site, or any other sites examined, would require force mains several thousand feet in length. By the first site, water from the river would be lifted by the pumps and forced to the reservoir with the least amount of power, friction, and expense of fuel to do the work. This site also commands an excellent and safe landing for boats supplying the works with coal.

“The analyses of waters lately taken at the Water-Works and at the Markley Farm clearly indicate the superior quality, purity, and healthfulness of the latter.

“It has been suggested that the offal from one or more distilleries, said to be in operation at New Richmond, some ten miles above the Markley Farm, would leave its taint in the water reaching the latter point. My answer is, that in this case the river, so slightly affected at New Richmond, and flowing ten miles to reach the Markley Farm, would, from agitation and dilution, and from the well-known self-purifying property of water, become pure.”

Regarding the other sites surveyed he said:

“The second, but objectionable, site for water-works was found some three miles above the Garden of Eden reservoir, and about the same distance below the mouth and offensive discharge of the Little Miami River. This location, although favorable in many respects, intercepts the drainage of the upper portion of the city, and all of that from the Miami Valley emptied into the Ohio River, which renders that site wholly inadmissible for water-works purposes.

“The valley of the Miami forms a water-shed of several hundred square miles in area. Upon the surface of this vast plain is deposited the dead carcasses of animals, and the droppings from cattle of all kinds. The ground is covered with decayed vegetable matter, and the soaking of stable-yards, hog-pens, slaughter-houses, distilleries, stagnant pools, etc. The refuse is washed off by rain storms into the Miami, which is the common receptacle, and thence into the Ohio River.

“It is only necessary, first, to disease the water, then disease the man; and it is clear, therefore, that water-works located below the Miami would, by wholesale pollution, disease the whole community.

“There is no city in the civilized world so regardless of the cleanliness and health of its citizens as to adopt a plan of water supply to foist upon them the concentrated filth from sewerage and the impurities of a stream, the water of which is only fit for mill-power, manufacturing purposes, and for cattle to drink; and I did not think that Cincinnati was emulous of setting the example.

“With regard to intermediate points between the county line and the mouth of the Little Miami River, I found the Ohio River lined with sand-bars, some of which projected from the shore nearly to the middle of the river, miles in length; while the bottom or bed of the river was, for the most part, covered with logs and craggy stones.”

His plan embraced the construction of pumping works for raising the water, first, from the river into subsiding and filter reservoirs, and then pumping it a second time into storage reservoirs. The water was to flow, through 10⅓ miles of 42-inch supply mains, into Eden Reservoir. The capacity of the pumps was estimated at 60 millions daily. The recapitulation of cost was:

For Engine-House and Grounds $ 312,790.00 For Pumping Engines 750,000.00 For Force Mains 92,130.00 For Storage Reservoirs 521,529.45 For Subsiding Reservoirs 560,252.00 For Clear-Water Well 14,669.60 For principal Supply Main, two lines 1,811,078.00 Miscellaneous expenses 60,500.00 ------------ 4,131,949.05 Add ten per cent 413,194.90 ------------- Total cost $4,545,143.95

In conclusion, he said:

“I, therefore, regard the first and best site, known as the Markley Farm, as one commanding all the advantages sought, where works may be erected combining greater simplicity of construction, economy of cost, and maintenance when put in operation, than could be built at any of the other points mentioned.”

No. 7.

MOORE’S SURVEY.

On the 23d of January, 1882, Mr. A. G. Moore, Superintendent of the Cincinnati Water-Works, submitted a communication to the Board of Public Works relative to the present condition of the pumping works and its future requirements. From it we arrange the following:

“The present pumps are deficient; that during the summer of 1881 the daily demands exceeded, at times, their capacity; and on one particular day there was a deficiency of over six million gallons. The engines are generally of light construction, and not sufficient for any increased loads. They are expensive in operation and maintenance. First-class engines of to-day would save two-thirds of the fuel used. The principal reliance, during the summer, is the large “Shield” engine, which is most extravagant on fuel, and has a wrought-iron force-main, of weak material, intrenched 35 feet below the surface of the street. Some of the boilers are of an age that require them to be treated with the greatest care, and should be condemned. The principal buildings do not afford protection or access to the pumps in case of derangement during average high water. The hill-top service is inadequate, and a larger and more comprehensive system should be adopted for the supply of the increasing territory.

“The subject of increasing capacity requires immediate attention; and should the removal of the works be deemed inadvisable, it will become essential to at once proceed with the erection of machinery, buildings, aqueduct, and aqua-fort at the old works. The cost of these improvements is placed at $1,394,000; reserve engine for 1884, $618,000; and sewer in Front Street, to carry the sewage below the works, $1,600,000. Total, $3,612,000.”

His plan for Markley Farm provides for one lift of 305 feet, with three compound pumping engines of 100 million capacity, subsiding and storage reservoirs, and one effluent-main 62 inches in diameter.

The estimate is condensed as follows:

Aqua-fort and buildings $ 410,000.00 Engines and boilers for 100 million capacity 1,255,000.00

Three subsiding reservoirs of earth and masonry } embankments, with 90 acres of water surface } 1,836,500.00

Effluent-main, including 55,000 feet of 62-inch pipe, } from the Farm to Eden Reservoir, and 18,000 feet } 1,804,000.00 of 48-inch, from Eden Reservoir to Harrison Avenue } Contingencies 460,000.00 ------------- Total $5,725,000.00

The important question is presented by him, which the public must decide, namely, whether it is a prudent policy to expend four millions of dollars to improve the old works, and retain all the expensive and unreliable machinery, and still supply an impure and turbid water; or to expend an additional two millions for an entire new system, from a source where a supply of pure and clear water can be secured, commensurate with the growing city.

He also embodies, by way of comparison, the following estimate for locating the works on the Kentucky side of the river:

For right of way and property, State and municipal 500,000 Aqua-fort and buildings 410,000 Three engines, with boilers complete 1,255,000 Subsiding Reservoirs 1,836,000 Effluent-mains, 23,000 feet 533,000 Tunnel for pumping main 270,000 Tunnel under the Ohio River, 3,000 feet 825,000 Thirty-inch main to Eastern Avenue, 22,500 feet 201,000 Contingencies 550,000 ---------- Total for Newport plan $6,381,000
