The workman's only real asset is his health, upon which his strength depends; it is his working capital. When he loses health he loses everything; he becomes a burden to himself, to his family, his friends, and the community. He lives by the wages he gets just as employers live by the work he does. The term industrial hygiene is used much more today than at any time in our history. It signifies the dawning of a new era, wherein the men, rather than the machine, receive the most anxious and skilled attention.
