Our practice was surprisingly large from the very first—large enough to please most young doctors, and large enough to prove a bore and a burden to students whose real interest lay elsewhere. The mill-hands were of somewhat turbulent inclinations; and besides their many natural needs, their frequent clashes and stabbing affrays gave us plenty to do. But what actually absorbed our minds was the secret laboratory we had fitted up in the cellar—the laboratory with the long table under the electric lights, where in the small hours of the morning we often injected West’s various solutions into the veins of the things we dragged from the potter’s field. West was experimenting madly to find something which would start man’s vital motions anew after they had been stopped by the thing we call death, but had encountered the most ghastly obstacles. The solution had to be differently compounded for different types—what would serve for guinea-pigs would not serve for human beings, and different human specimens required large modifications.
