CHAPTER XV.

MEN AND WAGES. 'SUB' FROM THE WOOD. A SUB-CONTRACTOR'S SCOUT AND FREE TRAVELLER.

"It is nearly midnight. I am game for another hour, are you?"

"Yes. I like talking on the quiet, it draws you together, you know; you feel for a time as if we all belonged to one family, although we do not, and don't want; that's a fact."

"Precisely, old pal. Let us grip and sip."

"Did any of your men ever play rough on you?"

"Not often; but I remember one. He was a good working hand, and I did not mean to lose him. Ted Skip was his name. This is how it occurred. One Saturday night I was in the village, and saw at the corner of a lane a man standing up in a cart spouting away fit to give him heart disease, or break a blood-vessel, and getting hot so quick, that I am sure he was going to beat record time. I believe he was fed on dictionaries and stewed Socialist pamphlets that did not agree with him. He was pouring it out. He said in effect that pretty nearly everybody was a thief except himself and his comrades, and that nearly all things were poison as they were, and unless we all did as he said we were fools and felons, and worse. Then he went on to say, beer was poison, tobacco was poison, and the way things were now, and all went on, was worse than poison. Then he talked about us, called us railway slave drivers and slaves, and I am sure there was no one or nothing that existed that was not poison to him except himself and what he possessed, and the fools that paid him. I got wild after a bit, hearing him lying away as fast as he could speak, and I shouted, 'You are all poison, you old bit of arsenic, for what is not ass about you is from old Nick.' He was then shouting out 'Your constitution is wrong. All the bills are of no use.' That was too much for me, so I pushed my way in and showed him my fist, and said, 'I'll soon show you whether all the Bills are of no use and whether my constitution is wrong. My name is Bill Dark, and there are numbers of people here that know I have never been sick or sorry since I was born, and I have taken beer and smoked tobacco from the time I was fifteen. In moderation, I believe in this country it does good to most of us, and pretty well all except those that are built up peculiar, and if you want to see if I'm of no use, come on; only get a sack first, so that the pieces of you that remain, and are large enough to be found, can be taken away and burnt to-night instead of later on. You understand what I mean.'

"Our chaps cheered me like mad, and I suppose old Arsenic thought his show was being wasted, for he threw up his arms and drove off, and we yelled him out of the village. Well, now you'll hear what came of it. Teddy Skip was there, and heard me say that beer and tobacco in moderation in this country I believe did good to most of us. A week or so passed, and I forgot all about old Arsenic when Teddy Skip came to me, and said, 'Guv'nor, after hearing you down in the village, and feeling a bit cold now and then, I thought I would try a pipe. I find it suits me, and is quite a friend, but it costs me nearly twopence a day, at least that is what I reckon it does. I have been with you a long time, and hope you won't mind another twopence a day just to buy the tobacco as you recommended to be used in moderation.'

"He had me there, so I made no bones about it, and said, 'Very well then, another twopence from Monday;' but I gave him a parting shot in this way, 'I know you are courting Mary Plush, and may be joined soon, but don't you come to me for a rise after each lot of twins is born, and say you have done a kindness to me and the public generally; because the wife and ten children lay is played out for increase of wages, and folks do with them that show as much moderation in size of families as remember I said should be used with beer and tobacco.' He began to move, and said smiling, as he cleared out, 'All right, guv'nor, thank you, I understand.'"

"That was pretty for you; but did I ever tell you how I got well insulted by one of my chaps?"

"No. Out with it."

"It was in my early days, about the first work I had on the piece. It was clearing and forming through a wood, and there were more rabbits there than trees. The contract was just started, and you know what the chaps are then, they want 'sub' nearly to their full time. Well, I was not flush, in fact they nearly drained me out, so the rabbits were too much for me, besides they were wasted in my sight where they were, simply gold running loose; so I bagged a fair lot, in fact as many as I could catch. Now, my men finding I was subbing them nicely seemed to think I was the man they had been looking to serve since they took to work, so I considered I ought to stop their game with another variety of sport. It does not do to let wrong ideas rest quiet in any man. It is not kind. It was Thursday, and on Saturday I should have a fairish draw for myself on account of work done; but as things were, I was nearly run out. About six wanted 'sub,' so I threw a rabbit to each of them, and said, 'That is tenpence, and it ought to be a shilling, for they are as big as hares and more feeding, and they are not half the trouble to cook.' They grumbled, so I growled out, 'Except on Saturdays, it is that this week and next most likely, or nothing, so choose your time.' One stayed behind, and said, 'Boss, just you look here: eightpence is enough for that, and too much, because I know it is poached, for I saw you doing a lift among the "furrers," and when I receive stolen goods I am paid for holding them, and chancing the consequences, and I don't pay for taking care of them. Do you understand? It is the last I take, and don't you mistake.'

"This 'riled' me, so I said, 'Off you go, or I'll flatten you out.' I was had there. Of course, he was at the same game as I had been, and rabbits to him were not exactly a novelty. Well, I carried on the fun there to such a tune that at last it became too hot. A dealer used to fetch them. He had an old cart. It looked like a baker's, and had some name on it, and there was a bit of green baize, and a basket or two, and a few loaves to keep up the illusion. We worked it till it turned on us, and the business had to be stopped."

"I never have done much at that. Not enough money for the risk to please me."

"Believe me, I have given up the game twenty years or more. I soon found in taking work by the piece I was bound to have a bit of capital, and, as a rule, what I want I get if it is to be had by anyone, and I generally find it is. I overdid it though, that's the worst of money, the more you get the more you want, and it's the biggest slave-driver out and spares no one. Well, complaints about poaching went up to head-quarters and I was called before the guv'nor. He said to me very sharp, 'I shall measure up your work unless from this day I hear no more of your poaching.'

"Of course I bluffed it a bit, but it was no good. However, knowing he always liked fun, he listened to me and I went off fond as a lamb. After promising I would keep watch on the men, which he did not let me finish saying before he had advised me to have assistance, he meant someone to watch me, I went straight for some joking, just to get the venom out of the subject. There is nothing like flattery to start a talk easy, so I said, 'You, sir, know a host of things more than me, and no doubt can explain how it was my father told me when I was a boy that all the family had a natural power of attracting animals. He said it was born in us. One day, sir, he drew me close to him and whispered, after feeling my head, 'You have the family gift very powerful.' You'll excuse me, sir, but I just name this because game always follows me about, and when these rabbits come on the work there is no mistake they are trespassing, and so I punish them by taking them into custody according to the law. When I walk up and down the line they seem to be that joyful, sir, as is real touching. They will come, and the bigger they are the more they seem to like me (between ourselves, that is you and me, to-night talking quiet, small 'uns don't suit me). I have not got the heart to frighten them away, and so they come to me, and sooner than let them go back to their savage life I take them up and become like a parent to them. You cut me so hard in price for the work, sir, I cannot afford to keep them long, so they have to partly keep me."

"Did your guv'nor stand that?"

"Yes. He was a good listener and always gave a man enough rope to hang himself."

"I should have punched your head if I had been him."

"Very likely you would have tried to, but he did not, so I went on to say, 'Well, sir, it is my undoubted belief the big rabbits down here can tell the difference between some letters and others, in the same way, I suppose, as they know the difference between some shot through their ears and a cabbage leaf in their mouth, or a horse and a fox; for they always run away from every cart but mine. I was just thinking I had said enough when the guv'nor had his turn and said:--

"'After what you have told me, attach a dozen white boards to the fencing, and have these words painted upon them in six-inch black letters--"Rabbits are vermin," and have your name put underneath. As you say some of them can read, that will cause them to cease following you. I am determined that this poaching shall be stopped once and for all.'

"'Excuse me, sir, but suppose they still will come to me after the notices are up, and I can't keep them away?'

"He answered, 'In such an event fix notice boards painted thus: "Any rabbit found trespassing upon this railway will be prosecuted with the utmost rigour of the law, and any rabbit found destroying the fences or hedges, or committing any damage of whatsoever kind will be shot.' Have your name put on it as before.'

"After that I thought it was time to go, and as I went out I could hear laughter. He had me, you know, so I was compelled to take to butcher's meat again throughout, and only a spare rabbit now and then went home to see his relations by aid of my mouth."

"What a row there is outside?"

"It's my dog barking. He must have heard you talk of rabbits. He is clever. I trained him so that I always knew when any engineers or inspectors were on the prowl. I call him 'Spot,' because he can 'spot' them so well. I made him do the spy business right round our end of the docks I was then on, and also on railway work."

"What did he do?"

"He used to do a tramp up and down quite naturally, about quarter of a mile in front of the tip and a quarter of a mile back of the gullet, or anywhere I had work, and not even the men knew he was on scout. He is the best watchman I have known; and so long as things were right and no bosses about he never came close to me unless I called him, but if anyone was prowling about he soon was close to me, and three pats communicated to him that I twigged, and he went on the scent again. He seemed to sniff out the faces of all my guv'nors in an instant, and looked anxious till I patted him three times, and then he turned up his eyes to meet mine, and a lovely beam of satisfaction came over him and he was as happy as he could be, and then he vanished. He was a sly dog, and useful too. He slept at the bottom of my bed in a basket. My wife did not like him on the bed; said dogs were dogs, and carried too many relations on their persons, so I hung a big basket to the tail end of our sleeping apparatus, and there he snoozed. Now, wherever I was, he was, or near to; he did not seem happy except he knew where I was. I always took him wherever I went, and on free pass. It's not very often I am travelling far, except when the works are finished; still, I easily trained him to be a good free traveller after a few trials, so that I never took a ticket for him. Not me. I always think it is hard, provided you have no luggage for the van, and have your dog well under control, that you cannot take him with you free, like you do a stick, an umbrella, or your pipe. A dog does not occupy a seat nor make a noise the same as a baby; but there, I don't mean to argue the question, and, personally, have no occasion, because I have not paid anything for my dog's travelling for years. The problem is solved as far as I am concerned, and the rest of creation will have to look out for themselves."

"How do you do it?"

"You mean, how does my dog, Spot, do it? In this way. I take my ticket, and before putting it into my pocket hold it in my hand for a moment. I then go on my right platform. Spot, that is my dog, then knows he is to get on that platform. He usually waits till a good many people want to pass, then he slips in beautifully quiet, sometimes by the side of a lady, or under cover of a group of passengers, and I have never known him noticed at the doors, as the ticket collectors are busy ticket snipping. I don't interfere with Spot's platform arrangements, for properly educated and well-brought-up dogs would object; but there is no doubt at some of the terminal stations the game could not be worked unless all the platforms are open. Suppose he was noticed on a platform, and they tried to find him, he was so good at hiding that they always thought he had gone; besides, they had plenty to do, and more serious business to look after. Once I saw they were searching for him, but they did not find him. He was not on the platform at all, but under a truck in the siding and enjoying the fun. He rested there, or at a convenient place till he heard the train coming, or saw I was about to get in. He timed his movements very cleverly, and has taken me by surprise sometimes, but he was sure to be under the seat, and hiding as quietly as a mouse, and taking no notice of me; not he.

"When I arrived at my station, if it was a big one, there was no trouble, I got out and Spot sneaked out without taking any notice of me, nor did I of him then. He used to make straight for the wall, and you bet he got out of the station quick, or was turned out. I have seen him driven out, as the porters took him for a stray dog. Once they threw a stool at him, it just caught his tail, and made him squall a trifle; but although it was a hard trial for me, I suppressed my feelings, as I had no ticket for him. I have known him sit down after following me out of the carriage, close up to the wall one end of a platform, and wait till the ticket-collector was busy sorting the tickets, and then Spot would walk out like a nobleman. I waited for him at a respectful and safe distance from the station, and then we had an affectionate meeting, and he had a biscuit and I had a drink, and we were a happy two. Spot is a real good dog, and as honest as the day, for I trained him in the right direction from the time he was a pup. He is a cool one; but there, it is a gift of nature like a swell singer's voice."

"Precisely."

"Now, listen; for once I was nearly had, even with Spot. There were about ten people in the compartment of a long carriage, and I sat next to a fly-looking chap, and only got in just in time, with my dog handy. Off the train went, and I was trying to consider what I ought to think about during the journey, when we all started, for Spot barked really fierce; and I said, 'Quiet.' Blessed if there was not another bark, and from another member of the dog creation. I knew it was not Spot, so I looked under the seat, and saw two bags, and Spot looking very warm and ready on one of them, with his head a little on one side. I knew it was live game, and I saw the other bag move. I thought the railway company had got the office and caught me, and that it was a 'put up job,' but I was wrong. It was all right. The chap next to me whispered in my ear that he was a rat-catcher, and had live rats in one bag, and his dog in the other, and they were travelling as passengers' luggage. I winked, and he did. Then it occurred to me, I was too friendly with him. However, of course his dog was trained to keep quiet, but mine was not in the presence of rats, so I had to look under again, and put out my stick, and say. 'Quiet, bosses.' Spot knew what that meant, and was quiet.

"Now, the other passengers steadied down very quickly, for of course they did not know we had not paid for the dogs. It was a fast local train and only stopped at the terminus, so there was no chance of their getting out before me at the station. I took care of that. It might have been awkward otherwise. The beauty of it was, this rat-catcher, I could see was not altogether satisfied when he came to dwell on it, for I fancy he thought I was a spy, and that he was caught; and I was not quite convinced he was not a detective. Still, a bold game generally pays the best; anyhow, I pretended I was dozing. It was evening, and when the train had barely stopped, after saying. 'Good-night all,' I got out first, and did not wait to see how the rat-catcher fared. I had Spot to look after, and was afraid the guard might have heard the barking; but he did not, for if he had we should both have been had lovely, all through a bag of rats. What my dog suffered from having to leave the game alone, it grieves me to think. All I know is, he was really bad for days after; but I should say the rats were tuning up to sing, 'We are all surrounded.'"

"I'm off now. Good-bye, old chap. Cheer up."

"Thank you for coming to see me, and having a good chat. It's lucky no one has heard us though, still, we have not confessed all. Have we?"

"Not exactly. Good-bye."

"Mind how you go, and I hope to see you to-morrow."

"All right; I'm safe enough, for I have been in too many squalls not to be careful. I won't say artful."

NOTES ON CONCRETE AND WORKS IN CONCRETE.

By JOHN NEWMAN, ASSOC. M. INST. C.E.

REVIEWS OF THE PRESS.

ENGINEERING:

_"An epitome of the best practice which may be relied upon not to mislead."_

"The successful construction of works in concrete is a difficult matter to explain in books."

"All the points which open the way to bad work are carefully pointed out by our Author with a pertinacious insistance which demonstrates his clear appreciation of their value."

IRON:

"As numerous examples are cited of the use of concrete in public works, and details supplied, _the book will greatly assist engineers engaged upon such works_."

THE BUILDER:

"A very practical little book, carefully compiled, and _one which all writers of specifications for concrete work would do well to peruse_."

"_The book contains reliable information for all engaged upon public works._"

"A perusal of Mr. Newman's valuable little handbook will point out the importance of a more careful investigation of the subject than is usually supposed to be necessary."

AMERICAN PRESS.

BUILDING:

"To accomplish so much in so limited a space, the subject-matter has been confined to chapters."

"_We take pleasure in saying that this is the most admirable and complete handbook on concretes for engineers of which we have knowledge._"

EARTHWORK SLIPS AND SUBSIDENCES UPON PUBLIC WORKS.

By JOHN NEWMAN, ASSOC. M. INST. C.E.

REVIEWS OF THE PRESS.

THE BUILDER:

"We gladly welcome Mr. Newman's book on slips in earthworks as an important contribution to a right comprehension of such matters."

"There is much in this book that will at all events guide the mind of the student to the points--and there are many of them--which have to be weighed by designers of engineering works, and which, if attended to and fixed on the memory, will certainly guard them against probable if not against possible slips in earthwork."

"There is much to read, and read carefully, on all these points."

"He then presents us with sixteen maxims to be observed, where practicable, in the consideration of the location of earthworks (hints as to what should be avoided, which are of considerable value).... The capital cost of a work and the cost of its maintenance may both be very sensibly reduced by attention to all the points alluded to by the author."

"We are glad to see that the author enters at some length into the subject of the due provision of drainage at the backs of retaining walls, a matter so often neglected or overlooked, and carries this subject to a far larger one, the causes which tend to disturb the repose of dock walls. His remarks on these matters are well worthy of consideration, and are thoroughly practical, and the items which have to be taken into account in the necessary statical calculations very well introduced."

"In conclusion we may say that there is plenty of good useful information to be obtained from this work, which touches a subject possessing an exceedingly scanty vocabulary."

"It contains an immense deal of matter which must be swallowed sooner or later by every one who desires to be a good engineer."

&c. &c. &c. &c.

BUILDING NEWS:

"Mr. John Newman, Assoc. M. Inst. C.E., has written a volume on a subject that has hitherto only been treated of cursorily."

"Useful advice is given which the railway engineer and earthwork contractor may profit by."

"The book contains a fund of useful information."

&c. &c. &c. &c.

BUILDER'S REPORTER AND ENGINEERING TIMES:

"The book which Mr. John Newman has written imparts a new interest to earthworks. It is in fact a sort of pathological treatise, and as such may be said to be unique among books on construction, for in them failures are rarely recognised. Now in Mr. Newman's volume the majority of the pages relate to failures, and from them the reader infers how they are to be avoided, and thus to form earthworks that will endure longer than those which are executed without much regard to risks."

"The manner of dealing with the subsidences when they occur, as well as providing against them, will be found described in the book."

"It can be said that the subject is thoroughly investigated, and contractors as well as engineers can learn much from Mr. Newman's book."

&c. &c. &c. &c.

This work is printed in a pearl type, and is so small, measuring only 2-1/2 in. by 1-3/4 in. by 1/4 in. thick, that it may be easily carried in the waistcoat pocket.

"It is certainly an extremely rare thing for a reviewer to be called upon to notice a volume measuring but 2-1/2 in. by 1-3/4 in., yet these dimensions faithfully represent the size of the handy little book before us. The volume--which contains 118 printed pages, besides a few blank pages for memoranda--is, in fact, a true pocket-book, adapted for being carried in the waistcoat pocket, and containing a far greater amount and variety of information than most people would imagine could be compressed into so small a space.... The little volume has been compiled with considerable care and judgment, and we can cordially recommend it to our readers as a useful little pocket companion."--_Engineering._

This work is not, in any sense, an elementary treatise, or history of the steam engine, but is intended to describe examples of Fixed Steam Engines without entering into the wide domain of locomotive or marine practice. To this end illustrations will be given of the most recent arrangements of Horizontal, Vertical, Beam, Pumping, Winding, Portable, Semi-portable, Corliss, Allen, Compound, and other similar Engines, by the most eminent Firms in Great Britain and America. The laws relating to the action and precautions to be observed in the construction of the various details, such as Cylinders, Pistons, Piston-rods, Connecting-rods, Cross-heads, Motion-blocks, Eccentrics, Simple, Expansion, Balanced, and Equilibrium Slide-valves, and Valve-gearing will be minutely dealt with. In this connection will be found articles upon the Velocity of Reciprocating Parts and the Mode of Applying the Indicator, Heat and Expansion of Steam Governors, and the like. It is the writer's desire to draw illustrations from every possible source, and give only those rules that present practice deems correct.
