“I left him bending over his wife and soothing her last moments, while I ran to overtake the party. We were the last to be admitted to the Chemistry Building. After that, with our automatic rifles we maintained our isolation. By our plans, we had arranged for a company of sixty to be in this refuge. Instead, every one of the number originally planned had added relatives and friends and whole families until there were over four hundred souls. But the Chemistry Building was large, and, standing by itself, was in no danger of being burned by the great fires that raged everywhere in the city. “A large quantity of provisions had been gathered, and a food committee took charge of it, issuing rations daily to the various families and groups that arranged themselves into messes. A number of committees were appointed, and we developed a very efficient organization. I was on the committee of defence, though for the first day no prowlers came near. We could see them in the distance, however, and by the smoke of their fires knew that several camps of them were occupying the far edge of the campus. Drunkenness was rife, and often we heard them singing ribald songs or insanely shouting. While the world crashed to ruin about them and all the air was filled with the smoke of its burning, these low creatures gave rein to their bestiality and fought and drank and died. And after all, what did it matter? Everybody died anyway, the good and the bad, the efficients and the weaklings, those that loved to live and those that scorned to live. They passed. Everything passed. “When twenty-four hours had gone by and no signs of the plague were apparent, we congratulated ourselves and set about digging a well. You have seen the great iron pipes which in those days carried water to all the city-dwellers. We feared that the fires in the city would burst the pipes and empty the reservoirs. So we tore up the cement floor of the central court of the Chemistry Building and dug a well. There were many young men, undergraduates, with us, and we worked night and day on the well. And our fears were confirmed. Three hours before we reached water, the pipes went dry. “A second twenty-four hours passed, and still the plague did not appear among us. We thought we were saved. But we did not know what I afterwards decided to be true, namely, that the period of the incubation of the plague germs in a human's body was a matter of a number of days. It slew so swiftly when once it manifested itself, that we were led to believe that the period of incubation was equally swift. So, when two days had left us unscathed, we were elated with the idea that we were free of the contagion.
