The coal companies in the anthracite regions keep thousands of surplus laborers on hand to underbid each other for employment and for submission to all exactions; hold them purposely ignorant when the mines are to be worked and when closed, so that they cannot seek employment elsewhere; bind them as tenants by compulsion in the companies' houses, so that rent shall run against them, whether wages run on or not, and under leases by which they can be turned out with their wives and children on the mountain-side in midwinter if they strike; compel them to fill cars of larger capacity than agreed upon; make them buy their powder and other working outfit of the companies at an enormous advance on the cost; compel them to buy coal of the company at the company's price, and in many cases to buy a fixed quantity, more than they need; compel them to employ the doctor named by the company, and to pay him whether sick or well; "pluck" them at the company's stores, so that when pay-day comes around the company owes the men nothing, there being authentic cases where "sober, hard-working miners toiled for years or even a lifetime without having been able to draw a single dollar, or but a few dollars, in actual cash," in "debt until the day they died;" refuse to fix the wages in advance, but pay them upon some hocus-pocus sliding scale, varying with the selling price in New York, which the railroad slides to suit itself; and, most extraordinary of all, refuse to let the miners know the prices on which their living slides--a fraud, says the report of Congress, "on its face."[18] The companies dock the miners' output arbitrarily for slate and other impurities, and so can take from their men five to fifty tons more in every hundred than they pay for.[19] In order to keep the miners disciplined and the coal-market under-supplied, the railroads restrict work so that the miners often have to live for a month on what they can earn in six or eight days; and these restrictions are enforced upon their miners by withholding cars from them to fill, as upon competitors by withholding cars to go to market.[20] Labor organizations are forbidden, and the men intentionally provoked to strike, to affect the coal-market. The laboring population of the coal regions, finally, is kept "down" by special policemen enrolled under special laws, and often in violation of law, by the railroads and coal and iron companies practically when and in what numbers these companies choose. These coal and iron policemen are practically without responsibility to any one but their employers, are armed as the corporations see fit with army revolvers, or Winchester rifles, or both, are made detectives by statute, and not required to wear their shields. They provoke the people to riot, and then shoot them legally.[21]
