“Well, as long as you have the moth, I suppose it can’t eat holes in my new carpet,” said Mrs. Slade. “I must put some cedar oil around, and kill the horrid things.”

“Oh, I beg of you, if you see any more to save them for me!” implored the professor. “There you are, my little pink beauty!” he exclaimed, as he put the moth in the case where it soon died, for the box contained cyanide of potassium, the fumes from which are almost instantly fatal to insect life. “That is worth many dollars to my college collection,” went on the scientist. “I would not have missed that for the world. This has been a lucky day for me. Let me see, what was I talking about?” and he looked at the boys through his powerful spectacles, while he absent-mindedly brushed the dust from his trousers.

“It was radium, and you said you’d like to go to Snake Island,” suggested Ned.

“Oh, yes, and I had told you about how my friend lost his life seeking the place. Indeed I would like to go, but I am afraid it is out of the question. However, I suppose some one will get the fortune some day,” and the professor carefully put the insect box in his pocket, looking the while, carefully over the carpet for more specimens.

“Well, that surely was a queer yarn,” remarked Bob. “I say, Ned, what do you say if we have something to eat on it. I’m hungry, and——”

“You don’t care who knows it!” finished Jerry with a laugh.

“That’s all right,” put in Ned good-naturedly, for the chums were almost like brothers, and made themselves perfectly at home in each other’s houses. “I guess it must be almost lunch time. I’ll go see if it isn’t ready. I reckon we can all eat some, even Professor Snodgrass, if he can spare the time from his specimens.”

“Oh, yes,” laughed the scientist. “I am ready——”

At that moment there came an interruption in the shape of a small boy, very excited, and out of breath, who dashed up on the porch, on which opened the library windows of the room where the three chums and the professor had been talking.

“Whoop!” yelled the small lad.
