AUGUST 30TH. We are alone on the island now, Barney and I. It was something of a jolt to have to sack Tayloe after all these years, but I had no alternative. The petty vandalisms I could have forgiven, but when he tried to poison Barney out of simple malice, he was standing in the way of scientific progress. That I cannot condone.
I can only believe the attempt was made while under the influence of alcohol, it was so clumsy. The poison container was overturned and a trail of powder led to Barney's dish. Tayloe's defence was of the flimsiest. He denied it. Who else then?
SEPTEBER 2ND. I am taking a calmer view of the Tayloe affair. The monastic life here must have become too much for him. That, and the abandonment of his precious guinea pigs. He insisted to the last that they were better-suited than Barney to my experiments. They were more his speed, I'm afraid. He was an earnest and willing worker, but something of a clod, poor fellow. At last I have complete freedom to carry on my work without the mute reproaches of Tayloe. I can only ascribe his violent antagonism toward Barney to jealousy. And now that he has gone, how much happier Barney appears to be! I have given him complete run of the place, and what sport it is to observe how his newly awakened Intellectual curiosity carries him about. After only two weeks of glutamic acid treatments, he has become interested in my library, dragging the books from the shelves, and going over them page by page. I am certain he knows there is some knowledge to be gained from them had he but the key.
SEPTEMBER 8TH. For the past two days I have had to keep Barney confined, and how he hates it. I am afraid that when my experiments are completed I shall have to do away with Barney. Ridiculous as it may sound there is still the possibility that he might be able to communicate his intelligence to others of his kind. However small the chance may be, the risk is too great to ignore. Fortunately there is, in the basement, a vault built with the idea of keeping vermin out, and it will serve equally well to keep Barney in.
