“Oh, landy!” cried the sentry who had apprehended the little scientist, peering into the box. “And to think one of them was loose on my post! Say, how long do you live after one bites you?” he asked anxiously. “There might be more where I have to walk, and if one nips me——”

“Don’t worry,” said Professor Snodgrass. “The bite of this centipede, while it is painful, is not deadly. Proper treatment will make you safe. But this is a most wonderful specimen. I had hoped to find one, but not so soon.”

“And didn’t you discover anything else?” asked an officer who had come out to see what the excitement was about.

“Anything else? No, but I’ll keep on looking, if you’ll let me. I may find a scorpion, though I am a bit doubtful about finding them so far north. However, I’m sure that just before I caught the centipede I saw a number of giant spiders with double stings. I’d like to look for them, and——”

“Excuse me, Lieutenant!” exclaimed the sentry who had caught the professor. “But would you mind giving me another post? He found all them animals he speaks of right here where I’m patrollin’.” And the soldier looked more frightened than if he had been told to charge on a battery of machine guns.

“I mean you saw no unauthorized persons trying to get through the lines, did you?” asked the lieutenant of the professor. “The insects were all you found?”

“Yes, but I haven’t found enough,” answered the scientist. “I should like more time. I couldn’t sleep, so I got up to hunt for specimens, and I was most successful.”

“I’m afraid we shall have to ask you to postpone your operations until morning,” said the officer with a smile. “We want you to feel free to advance the cause of science as much as you can, but a war camp at night is a nervous sort of place, and the least alarm disturbs a large number of men.”

“I’m sorry,” said Mr. Snodgrass. “I can, of course, wait until it is light. There may be more scorpions and centipedes out then.”

“I’m glad I go off duty,” murmured the sentry.
