But these hereditary inefficients do not alone compose the surplus labor army. There are the skilled but unsteady and unreliable men; and the old men, once skilled, but, with dwindling powers, no longer skilled. {3} And there are good men, too, splendidly skilled and efficient, but thrust out of the employment of dying or disaster-smitten industries. In this connection it is not out of place to note the misfortune of the workers in the British iron trades, who are suffering because of American inroads. And, last of all, are the unskilled laborers, the hewers of wood and drawers of water, the ditch-diggers, the men of pick and shovel, the helpers, lumpers, roustabouts. If trade is slack on a seacoast of two thousand miles, or the harvests are light in a great interior valley, myriads of these laborers lie idle, or make life miserable for their fellows in kindred unskilled employments. A constant filtration goes on in the working world, and good material is continually drawn from the surplus labor army. Strikes and industrial dislocations shake up the workers, bring good men to the surface and sink men as good or not so good. The hope of the skilled striker is in that the scabs are less skilled, or less capable of becoming skilled; yet each strike attests to the efficiency that lurks beneath. After the Pullman strike, a few thousand railroad men were chagrined to find the work they had flung down taken up by men as good as themselves. But one thing must be considered here. Under the present system, if the weakest and least fit were as strong and fit as the best, and the best were correspondingly stronger and fitter, the same condition would obtain. There would be the same army of employed labor, the same army of surplus labor. The whole thing is relative. There is no absolute standard of efficiency. * * * * * Comes now the tramp. And all conclusions may be anticipated by saying at once that he is a tramp because some one has to be a tramp. If he left the "road" and became a _very_ efficient common laborer, some _ordinarily efficient_ common laborer would have to take to the "road." The nooks and crannies are crowded by the surplus laborers; and when the first snow flies, and the tramps are driven into the cities, things become overcrowded and stringent police regulations are necessary. The tramp is one of two kinds of men: he is either a discouraged worker or a discouraged criminal. Now a discouraged criminal, on investigation, proves to be a discouraged worker, or the descendant of discouraged workers; so that, in the last analysis, the tramp is a discouraged worker. Since there is not work for all, discouragement for some is unavoidable. How, then, does this process of discouragement operate?
