Professor Snodgrass, during this episode, had taken no part in the conversation, remaining quietly in his place, scanning the water for a glimpse of some rare aquatic insect. At times he would dip into the river a small net he carried, and, bringing it up filled with mosquito wrigglers, or other forms of life, he would gravely examine his catch through a magnifying glass.

“Ah, here is a rare one!” he would occasionally cry. “A triple-jointed worm. But I don’t understand how it got into the water, as it is a form of land life. This is very puzzling. I must make notes on this. Perhaps the worm, having lived on land all its life, is going to become aquatic in his habits, as the whale did centuries ago. It is very strange.”

“Let’s see the worm, Professor?” requested Ned, when he had adjusted the motor to work smoothly, and while Jerry was steering in and out to avoid floating logs.

“There it is,” said the scientist, lifting the specimen out of one of the glass-topped boxes. “A beautiful creature! Most perfect! And yet I cannot account for it being in the water. I shall devote a good deal of space in my new book to this find. Perhaps I am the first to discover it, and, if so, I shall be made an honorary member of the Society for Advanced Scientific Research. A most beautiful and perfect specimen!”

“Why, it’s an angle worm—a fish worm!” cried Bob, as he caught sight of the wriggling creature. “A common, ordinary angle worm!”

“Of course it is,” agreed the professor. “I know that. It is, as you say, an angle worm—angulus vermis it might be called or even vermis lophius piscatorius. The first Latin words being merely indicative of angle and worm, while the latter, which I prefer, indicates the curious fish known as the angler, and which is said to catch other fish by angling for them with some attachment to its head, which resembles a baited hook. Of course it’s an angle worm, Bob, but the funny part of it is how did it get in the water?”

“Easily enough,” spoke Ned. “The river is much higher than usual, and I suppose it has overflowed some bank, and washed the poor worms out. I’m afraid, Professor, that you can’t claim to be the discoverer of a new kind of worm.”

“Oh pshaw! I guess you’re right!” exclaimed Uriah Snodgrass in disappointed tones. “That accounts for it. Well, I don’t want the specimen then,” and he tossed it back into the water. There was a little swirl, amid the muddy waves, and something grabbed the floating worm.

“Fish!” cried Bob. “There are lots of fish around here, fellows. I’m going to catch some for dinner.”

“There he goes again!” cried Ned with a laugh. “We’ve just had breakfast, and yet he’s thinking of the next meal. Oh, Bob! You’re hopeless.”
