"Carnes, did you ever see a case of snow blindness?"

The operative looked up in surprise.

"Yes, I have. I had it myself once in Maine. Now that you mention it, his case does look like snow blindness, but such a thing is absurd in Washington in August."

Dr. Bird rummaged in his desk and drew out a book, which he consulted for a moment.

"Now, Carnes," he said, "I want some dates from you and I want them accurately. Don't guess, for a great deal may depend on the accuracy of your answers. When was this mental disability on the part of the President first noticed?"

Carnes drew a pocket diary from his coat and consulted it.

"The seventeenth of July," he replied. "That is, we are sure, in view of later developments, that that was the date it first came on. We didn't realize that anything was wrong until the twentieth. On the night of the nineteenth the President slept very poorly, getting up and creating a disturbance twice, and on the twentieth he acted so queerly that it was necessary to cancel three conferences."


Dr. Bird checked off the dates on the book before him and nodded.
