“Do you know this gentleman?” asked the corporal of Jerry.

“Yes, he is a very good friend of ours.”

“Then you may release him,” went on the corporal to Kelly. “And we are sorry for what happened.”

But it is doubtful if Professor Snodgrass heard him, for the little scientist was again reaching forward to get something from the shoulder of the corporal. This time he succeeded, and those gathered about had a glimpse of a white, fluttering object.

“One of the finest and largest white moths I have ever caught!” exclaimed the delighted professor. “I thank you!” he added, as though the corporal had done him a great favor by serving as a perch for the insect.

The excitement caused by the capture of the “prisoner” soon passed, and the corporal went back to his rest, while Ned, Bob and Jerry, whose tour of duty was up, took Professor Snodgrass in charge.

They explained the matter to the officer in charge of their barracks, and a spare bunk was found for the college instructor.

But he did not seem inclined to use it. He wanted to sit up and enter in his note book something about the specimens he had caught in such a sensational manner, but when it was explained to him that to have lights in an army camp after ten o’clock was against the regulations, except in cases of emergency, he put out his pocket electric lantern and dutifully went to sleep, with his specimen boxes under his bed.

The next day Professor Snodgrass told the boys that so many students had enlisted from Boxwood Hall that the teaching force was greatly reduced.
