think I do," said Dr. Bird slowly. "It was a good deal as if you had seen a glass filled with a pale red liquid and someone had dumped black ink into the fluid and hid the red color. You would know that the red was still there, but you wouldn't be able to see it through the black."
"That's exactly what it was like, Doctor; you have described it better than I can. At any rate, after it got real dark I heard a low whistle from the roof. No. 9764 made a struggle to get up for a moment and then lay quiet again. The whistle sounded again and then I heard some one call 'Caruso.' Everything was quiet for a while and then the same voice called again and said some stuff in a foreign language that I couldn't understand. I kept perfectly quiet to see what would happen.
"For about ten minutes the room remained perfectly dark, as I have said, and all the while I could hear that whining noise. All of a sudden it began to sound in a lower note and then I could see the lights again, very dimly and like the black ink you spoke of was fading out. The note got lower until it stopped altogether, and the lights came on brighter until they were normal again. Then I heard a scraping noise on the roof and the noise I had heard at first like a big electric fan. I looked at the clock. It was two-twenty.
"For a few minutes I wasn't able to collect my wits. When I got up off of No. 9764 at last he stared at me as though he didn't know a thing, and I heaved him back into his bed and ran to the door to summon an outside guard. I could still talk in a husky whisper, but not loud, and I wasn't surprised when no one heard me. My orders were not to let No. 9764 out of my sight, but this was an emergency, so I left the ward and found a guard. It was Madigan and he was standing on his beat staring at nothing. When I touched him he looked at me and there was the same vacant look in his eyes that I had seen in the prisoner's. I talked to him in a whisper, but he didn't seem to understand, so I left him and went to a telephone and called for help. Mr. Lawson, the warden, got here with guards in a couple of minutes and I tried to tell him what had happened, but I couldn't talk loud, and I was afraid to take the fish bowl off my head."
hat happened next?"
"Mr. Lawson took me to his office, and on the way we passed under an arc light. As soon as I got under it I begin to feel better, and my voice came stronger. I saw that it was doing me some good and I stopped under it for an hour before my voice got back to normal. It seemed to clear the fog from my brain, too, and I was able, about four o'clock, to tell everything that had happened. Mr. Lawson seemed to think that my brain was affected as well as the others' and he sent me to the hospital. That's all, Doctor."
"Do you feel perfectly normal now?"
