Part 11

This crop attains its best development in a rich sandy loam in which there is plenty of organic matter. Lettuce thrives best during the early spring or late autumn and will not withstand the heat of summer. In order that the leaves may be crisp and tender, it is necessary to force the growth. The usual method of growing lettuce for home use is to sow the seeds broadcast in a bed and remove the leaves from the plants as rapidly as they become large enough for use. A much better method is either to thin or transplant the seedlings and allow the plants to form rather compact heads and then cut the entire plant for use. In the Southern States the seeds may be sown during the autumn and the plants allowed to remain in the ground over winter. At the North the seeds may be sown in a hotbed or cold frame and the seedlings transplanted to the open ground, or the seeding may be in rows in the garden and the plants thinned to 5 or 6 inches in the row. Lettuce may be grown in rows about 12 inches apart. In order to produce crisp and tender lettuce during the summer months, it may be necessary to provide some form of partial shading.--(F. B. 255; N. Y. E. S. 208; N. Car. E. S. 147; Tenn. E. S. 2; Purdue Ind. E. S. 66 and 84; Kas. E. S. 70.)

LLEREN (_Calathea allouya_).

This vegetable, although cultivated in Porto Rico for a long time, is not extensively known. The plant at a cursory glance resembles a canna. The edible tubers, which are formed in great profusion, can be eaten boiled like potatoes; but, unlike potatoes, they do not become soft, but appear hard and crisp after prolonged boiling. Lleren somewhat resembles boiled sweet corn in taste, and most people pronounce it delicious without needing to acquire a taste for it. The best soil for lleren is a rich, moist, well-drained loam, which is usually benefited by an application of wood ashes or sulphate of potash; an excess of nitrogen causes the production of large tops and few tubers. The stools or roots immediately adhering to stalks are the parts used for propagating; the tubers will not germinate. Lleren should be planted at intervals of 2 feet in rows 4 feet apart, and cultivated like any other vegetable. It requires ten to fifteen months to mature tubers, which are 3/4 to 1 inch in diameter, and may be harvested at any time when large enough, but can be left in the ground for a long time without spoiling. It is a good shipper and if introduced into the northern market it would soon create a demand.--(P. Rico E. S. 7.)

MARTYNIA (_Unicorn Plant_).

The curious, long beaked fruit is used for pickles. The plants are quite hardy and ornamental, the fruit being no less conspicuous for its odd shape than the large wax-like flowers of whitish color with purple and yellow spots.--(Mich. E. S. 20.)

MELON--MUSK.

_Soil and Location._--The soil for muskmelons must be well drained and contain an abundance of humus and readily available plant food. If these conditions are met, it matters little what the particular type of soil may be. A knoll or ridge sloping gently to the south and protected by timber on the north and west furnishes an ideal site for melons. Such a location will usually produce earlier melons than a north or west slope and is better than a level area because the soil dries out more quickly after a rain, thus permitting more timely tillage in a wet season, and resulting in the production of melons of better flavor. It is only in dry seasons that low, flat land, unless thoroughly tile-drained, produces good melons. The condition of the soil in reference to its supply of humus has a marked influence upon the welfare of the melon crop. Because of its abundance of humus, newly cleared timber land is well adapted to melon culture, but is difficult to work on account of the stumps and roots. Land slightly deficient in humus can be put in condition for growing melons by plowing under a clover sod, or a crop of cowpeas or rye, or a coat of manure applied broadcast. If melons are to be grown as one of the crops in a regular rotation, they should constitute the crop immediately following the leguminous crop designed to add humus and nitrogen to the soil. In regions where winter wheat and clover are grown, a rotation of wheat, clover and melons is highly satisfactory. Another good rotation would be: oats, clover, melons, corn. In regions where clover does not thrive and wheat and oats are not grown, a rotation of corn, cowpeas, and melons may be employed, or the rotation extended by seeding to grass after the melons are harvested. Even with careful attention to rotation and the incorporation of humus by plowing under catch crops or manure, ordinary farm land--including good corn land--is not sufficiently rich to produce a satisfactory crop of melons without the use of fertilizing material in the hills. It is only on garden soil that has been made exceedingly rich by repeated applications of manure, that it is wise to attempt to grow melons without special treatment of the hills.

_Manure for the Hills._--The manure for use in the melon hills is ricked up in the fall in long low piles, about eight feet wide and two or three feet deep. The sides of the pile are made as nearly perpendicular as possible and the top is flattened so that rains will soak in instead of running off. Sometimes a layer of dirt about three inches deep is placed on top of the manure to help retain the moisture. Early in the spring, work is commenced on the manure to put it in condition for use. The pile must be cut down and the manure turned and mixed until it is thoroughly decomposed and of fine texture. Formerly this work was done by hand with a fork, and entailed a large amount of labor. Now some of the large growers do all this turning of the manure with a disk and plow. The pile is worked three or four times at intervals of one or two weeks.

_Time of Planting._--The melon is a warm season crop, and unless the soil is warm and the weather favorable the seeds will not germinate nor the plants grow. It is therefore usually unwise to plant in advance of the normal season in the hope of securing an early crop. Occasionally, such plantings do well, but usually the stand is poor, necessitating much replanting, and the early plants which do survive are likely to be so badly stunted by reason of the cool weather that they do not mature their crop much in advance of the later plantings which have had the benefit of warm weather from the start.

_Preparations for Planting._--Melon ground should be plowed early in the spring, or replowed if it was broken in the fall. After plowing, it should be thoroughly pulverized by the use of a disk or harrow, or both, and then kept in good, friable condition by occasional working until planting time arrives. Shortly before planting is to begin, the field should be furrowed out both ways with a single-shovel plow or a one-horse turning plow. The furrows should be about six inches deep, and as far apart as the hills are to be placed. On some soils melon vines make only a moderate growth and the hills may be planted as close as four feet apart each way; but on rich soil, where they make a stronger growth, they should be at least five by five, and in some cases six by six. After the land is furrowed out the rotted manure is applied at the intersections of the furrows. From a quart to a half-peck of manure is used for each hill, depending upon the quality of the manure and also the quantity available. The manure is dropped into the bottom of the furrow, and either mixed thoroughly with the soil there, and covered with a layer of pure soil in which to plant the seed, or is merely covered with the soil without any mixing. The latter method seems to give fully as good results as the former, especially when a small quantity of manure is used, and is a great saving of labor. In either case, especial care should be taken to compact the soil over the manure so that when the seed is planted it will not suffer from lack of moisture by reason of any vacant air space in or about the mass of manure. Sometimes the manure is covered with soil by merely plowing a furrow on each side of the furrow containing the manure, but unless the soil is in exceedingly fine condition, this method is not as satisfactory as using a hoe and giving each hill individual attention. In making the hill, some planters compact the soil with the hoe, while others use the feet. When ready for planting, the hill should be practically level with the general surface of the field. If too low, the hill will become water-soaked in case of rain and the seeds or plants injured; if too high, there is likely to be insufficient moisture to insure proper germination and growth.

_Planting the Seed._--If the hills have been made more than a few minutes before the seed is dropped, the top layer of dry soil should be scraped aside with a hoe so that the seed may be placed in immediate contact with moist soil. The area thus prepared for planting the seed should be at least six inches across, and should be smooth and level. From ten to fifteen seeds should be scattered uniformly over this area, and covered with about half an inch of fine, moist soil. This should be firmed with the back of the hoe and then covered with a sprinkle of loose dirt to serve as a mulch. If a heavy rain packs the top of soil and a crust is formed before the plant appears, it is wise to go over the field and carefully break the crust over each hill by means of a garden rake. The method of preparing the hills and planting the seed described above applies to field rather than garden conditions and to soils of medium rather than excessive fertility. In a market garden where the soil is exceedingly rich as a result of repeated manuring for onions or cabbage, and is in fine tilth, it is a common practice to sow the melon seed in drills six to eight feet apart, by means of a garden seed drill. This is done without any special preparation of the soil where the plants are to stand, or application of fertilizing material other than manure applied broadcast before plowing.

_Thinning._--While ten to fifteen seeds are planted per hill for the sake of insuring a full stand, only two, or at most three, plants are left to make the crop. Thinning is usually deferred until the plants have become fully established, and the struggle against the striped beetle is nearly over. However, the plants must be thinned before they begin to crowd badly, or those which are to remain will be stunted in growth. Usually the thinning is completed by the time the plants have four rough leaves. If the seed has been well scattered in planting, so that each plant stands apart by itself, the superfluous plants may be pulled with the fingers, but extreme care must be taken to avoid disturbing the roots of the remaining plants. Sometimes the plants are cut off with a knife or shears, instead of being pulled, and thus all danger of disturbing the roots is avoided. If the seeds have been sown with a drill as in market gardening practice, the plants are usually thinned to one in a place at distances of two to two and one-half feet in the row.

_Transplanting._--Since it is impossible to increase the earliness of the crop to any great extent by early planting in the field, growers have adopted the transplanting method. This makes it possible to plant the seed three or four weeks earlier than would otherwise be feasible, and to grow the plants under controlled conditions of temperature and moisture during their most critical period. It also simplifies the matter of protection from striped beetles. The main objections to this method are the expense for sash, and the difficulties attending the transplanting. A melon plant will not survive transplanting if the root system is disturbed. For this reason the seed is sown on inverted sod, in pots or in dirt bands. The dirt bands are used almost exclusively by commercial growers. These are thin strips of wood veneer, three inches wide and eighteen inches long, scored at intervals of four inches so that they can be bent without breaking. When folded ready for use, each band resembles a small strawberry box without the bottom. These bands are placed close together in a hotbed and filled level full with fine, rich soil. With a block of wood shaped for the purpose, the soil within the bands is pressed until it is 1/2 to 3/4 inch below the top of the band. If only part of the dirt is put in at first, and is pressed down firmly, then the rest of the dirt put on and pressed, the soil in the band will be more compact throughout and will hold together better in the transplanting than if the dirt were pressed only once. Unless the soil used was very moist, the bed is then thoroughly watered. Next, three seeds are placed in each band. These are covered with fine, loose soil deep enough to fill the band. This soil is not firmed. The hotbed for melon plants should have full exposure to light and be maintained at a high temperature--about 85 degrees F. during the day and 65 to 70 degrees at night. As much ventilation should be given as the weather will permit, and care exercised to avoid overwatering. As soon as the plants are well started, they are thinned to two in a band by cutting off the extra plant with a sharp knife. When the plants are about four weeks old from the planting of seed they will be in the right condition for transplanting to the field. They are then compact, stocky plants with about four rough leaves. If allowed to remain longer in the bed they begin to stretch for light and are of little value for planting, for the long naked stems, unable to support themselves and unaccustomed to direct sunlight, would easily be sun-burned, and the plants seriously checked if not killed outright.

_Cultivation._--Whether the melons are transplanted from a hotbed or grown from seed planted in the field, the tillage of the crop should begin as soon as the plants can be seen. In the case of transplanted plants, this will be the same day that they are set in the field. The early tillage should be deep, and as close to the plant as it is feasible to run the cultivator. The object of this deep tillage is to establish a deep root system so that the plants will not suffer so severely from dry weather later in the season. In the case of a field planted crop it is not feasible to cultivate so close to the plants early in the season because of the danger of tearing out the little plants. For this deep tillage a one-horse five-shovel cultivator, often weighted with a rock, is the tool most commonly used. It is customary to follow this with a "boat" or a 14-tooth cultivator to more fully pulverize the soil. Tillage is usually given after each rain or at least once each week so that the soil is maintained in a loose friable condition. In addition to the cultivation with a horse, much hand hoeing is required close about the plants. Any crust forming after a rain, is broken, and fresh, moist soil drawn up about the plant. Crab grass and weeds appearing in the hill are removed by hand. Most growers cease tillage and lay-by the crop as soon as the vines have run enough to interfere with the cultivator. The experience of a few growers who have turned the vines and kept them in windows so that tillage could be continued until the picking season opened, indicates that a departure from the old method is likely to insure better development of the melons and a longer picking season, though the first fruits may not ripen so early. There is another distinct advantage in this turning of the vines, in that the gathering of the crop is greatly facilitated and there is no injury to the vines from tramping.

_Seed._--No matter what variety of melon is grown, it is extremely important that pure seed be planted if good melons are to be produced. The melon deteriorates very rapidly under careless methods of seed selection. None but the very choicest specimens of the desired type, from productive vines, should be selected for seed. It is unsafe to cut seed from a field in which more than one variety of melon is grown; for seed from such a field would likely be very badly mixed, and the product undesirable for market. If a grower has sale for all his good melons, it may be cheaper for him to purchase his seed than to save it. But here again there is danger of procuring inferior seed, for much of the melon seed on the market is cut without careful selection, in order to meet the demand for cheap seed. Even cull melons are used to supply this demand. Such seed is expensive at any price. The difference in the cost of good seed and poor seed is insignificant when compared with the advantages to be derived from the use of seed which can be depended upon to produce melons of a given type.

_Picking._--There is considerable difference of opinion as to the exact stage of maturity at which melons should be picked for shipment. If allowed to become too ripe before picking, they become soft by the time they reach the market, and often must be sacrificed in order to effect an immediate sale. If picked too green, the melons reach market in firm condition, but are lacking in flavor, and are not desired by the best trade. It is a nice point to pick melons at such a degree of ripeness that they will reach the market in firm condition, and yet possess the requisite flavor. The farther from market the melons are produced, the less mature they must be when picked. Furthermore, the rapidity of softening after picking varies with the temperature to which the melons are subjected. The cooler they can be kept after picking, the longer they can be allowed to remain on the vines and the better flavor they will have. It is, therefore, essential that the melons be placed in the shade as soon as possible after picking, and be kept shaded until they are loaded into the car. For the same reason, riper melons can be shipped under the refrigeration than in ventilated cars. It is also true that melons shipped during excessively hot weather, unless under refrigeration, will soften more rapidly than those shipped during cooler weather. The condition of the vines and the rapidity of ripening of the melons in the field will also have a bearing upon the stage of maturity at which they should be picked. Early in the shipping season, when the vines are in full vigor and the melons ripening slowly, the fruits may safely be left upon the vines until more mature than would be safe later in the season when the plants have become somewhat weakened, or, by reason of excessive heat, the melons are ripening very rapidly. Melons should not be picked at the same degree of maturity under different conditions of ripening, methods of transportation, and distances from market.

While it is true that no rule can be given for picking melons that will apply under all conditions, and that the grower must exercise judgment in reference to each day's picking, the ideal will be attained when the conditions are such that the melons will reach the market in the best condition if picked as soon as the fruit will part readily from the stem when the latter is pressed with the thumb or finger. There is a tendency among some growers to pick considerably before this point has been reached, in order to run no risk of the melons becoming soft in transit. In fact, some growers make a practice of picking the melons before a crack appears about the stem or any change of color takes place, even on the under side of the fruit.

_Market Demands._--While various types of muskmelon may be disposed of upon a local market, there are certain types which are recognized as standards in the large city markets; and it is seldom wise to attempt to force upon a general market a variety not recognized as a standard in that particular market. In the Chicago market the sorts most in demand are the Netted Gem, or Rocky Ford type, and the Osage.--(Ill. E. S. 124, 139; F. B. 255; S. Dak. E. S. 67; N. Hamp. E. S. 70, 96; N. Y. E. S. 200; N. Mex. E. S. 63.)

MELON--WATERMELON.

The cultivation of the watermelon is practically the same as for the muskmelon, except that the plants grow larger and require more room for development than those of the muskmelon. Watermelons require that the soil should contain a larger percentage of sand than muskmelons, and that the land should be quite rich. Watermelons should be planted 10 feet each way between the hills, or in drills 10 feet apart and thinned to 3 feet apart in the drills. The watermelon seedlings must be protected from the cucumber beetle until the foliage becomes toughened. Watermelons readily group themselves into six classes based upon the color or characteristics of the skin or external appearance. It does not necessarily follow that in the proposed classification the fruit of each variety will all be of the same form to which it is referred; for, as every melon grower knows, the fruits in each hill vary more or less; but if everything is normal and favorable for their development the characteristic form or that typifying the variety will predominate. The larger the experience of the grower, the easier it is for him to understand these various types. In order to get the true type of each variety, it is important that the seeds be secured directly from the seedsman who first introduced them thus avoiding complications or errors.--(F. B. 255; N. H. E. S. 86; Ind. E. S. 123; N. Mex. E. S. 63; S. Dak. E. S. 67.)

MUSTARD.

Almost any good soil will produce a crop of mustard. The basal leaves of mustard are used for greens, and as the plants require but a short time to reach the proper stage for use frequent sowings should be made. Sow the seeds thickly in drills as early as possible in the spring, or for late use sow the seeds in September or October. The forms of white mustard, of which the leaves are often curled and frilled, are generally used. Mustard greens are cooked like spinach.--(F. B. 255; Mich. E. S. 20; La. E. S. 90.)

NASTURTIUM.

The hardiness and unsurpassed beauty of this plant should make it a favorite near every home. The seed pods just before beginning to ripen make a delicious flavoring for pickles.--(Mich. E. S. 20; S. Dak. E. S. 68.)
