The sleeping rooms are of two kinds, individual rooms and dormitories. Those men who are of a better rank, that is, those who have been working long, or who are doing a higher grade of work, and those who have "boss" positions, occupy the separate rooms; while the general class of workers sleep in the dormitories. When it comes to the question of pure air, considerable difficulty arises. Some of the separate rooms have no outside window, though the partitions between the rooms rise only to a certain height, thus giving common air to the whole floor. Even where good ventilation facilities exist, it seems difficult to make the men keep the windows open. As regards ventilation, however, the industrial homes are, as a rule, better than the lower class workingman's hotels, and are improving in this respect. The beds are iron, single beds. The bed clothing and the rooms themselves are clean and fumigated regularly. A reading room is also provided where daily papers and popular magazines are kept, and where the men may write. In some cases, a smoking room adjoins. Meetings of a devotional character, to which the men may come or not as they see fit, are often held in the reading room. The support that renders the industrial home possible is the waste product of the city. This material is rubbish of all kinds imaginable. In connection with each industrial plant are kept a number of horses and wagons, mostly one-horse wagons. Each driver of a wagon has a definite route to cover regularly. Passing over his route, he collects everything of which people are glad to be rid. Waste paper, old clothes, old furniture, and the like, are the principal articles he collects. Many good people, persuaded of the good work the Army is doing, save up their store of odds and ends until the Army wagon shall call, often giving things away which they would not have thrown away or given any one else, unless it would be to sell them to an old-clothes man. The driver returns with his load to the warehouse. From his wagon the material is conveyed by means of an elevator to the sorting room in the second story, whence the greater quantity goes at once to the baling machine in the form of waste paper. Any articles that may be of use, such as shoes, clothing of any kind, books, crockery-ware, bottles, pots, kettles, etc., are placed in their respective bins and finally, repaired, find their way to the retail store. Heavy articles, such as stoves and furniture, do not go up in the elevator, but are retained on the first floor, where they go, first to the repairing and storage room, and then out to the stores. The paper and rags, when baled, are sold to the nearest paper mill for a good price. Some idea of the amount of this class of material may be gained from the fact that the average amount of paper sold by the Industrial Department in the United States is about 2,500 tons per month.
