At this point the Doctor came up. He shook hands with Willis and went into his tent. I urged Willis to follow, but he would not. I offered to lead the conversation into the matter in which he was so greatly interested, but he would not consent.

The Doctor reappeared. "Lydia will be here to-night," he said.

"You surprise me, Doctor."

"Yes; but I am now pretty sure that we shall be here for a week to come, and we shall not move our camp before the rear division moves. Lydia will find enough to do here."

Willis soon took his leave. I accompanied him for a short distance; on parting with him I told him that he might expect to see me again at night.

"What!" said he; "you are going to leave the Doctor?"

"Yes," I replied; "expect me to-night."

Willis looked puzzled; he did not know what to say, and said nothing.

When I entered the Doctor's tent, I found him busily writing. He looked up, then went on with his work. Presently, still continuing to write, he said, "So Willis is angry."

"Why do you say so, Doctor?"
