"The situation was critical. The explosions of the powder magazines had broken all the windows of the Chemistry Building, so that we were exposed to the germs from the corpses. The sanitary committee was called upon to act, and it responded nobly. Two men were required to go out and remove the corpses, and this meant the probable sacrifice of their own lives, for, having performed the task, they were not to be permitted to re-enter the building. One of the professors, who was a bachelor, and one of the undergraduates volunteered. They bade good-bye to us and went forth. They were heroes. They gave up their lives that four hundred others might live. After they had performed their work, they stood for a moment, at a distance, looking at us wistfully. Then they waved their hands in farewell and went away slowly across the campus toward the burning city.

"And yet it was all useless. The next morning the first one of us was smitten with the plague--a little nurse-girl in the family of Professor Stout. It was no time for weak-kneed, sentimental policies. On the chance that she might be the only one, we thrust her forth from the building and commanded her to be gone. She went away slowly across the campus, wringing her hands and crying pitifully. We felt like brutes, but what were we to do? There were four hundred of us, and individuals had to be sacrificed.

"In one of the laboratories three families had domiciled themselves, and that afternoon we found among them no less than four corpses and seven cases of the plague in all its different stages.

"Then it was that the horror began. Leaving the dead lie, we forced the living ones to segregate themselves in another room. The plague began to break out among the rest of us, and as fast as the symptoms appeared, we sent the stricken ones to these segregated rooms. We compelled them to walk there by themselves, so as to avoid laying hands on them. It was heartrending. But still the plague raged among us, and room after room was filled with the dead and dying. And so we who were yet clean retreated to the next floor and to the next, before this sea of the dead, that, room by room and floor by floor, inundated the building.
