“I don’t intend to,” declared the stout lad, helping himself to more fish.

They started off again after dinner, and making good speed, aided by the current of the river, they found themselves that night on a small lake into which the stream emptied. They tied up near shore, and, the collapsible bunks being let down, they retired, after sitting up for a while, talking over the events of the day.

“This sure is sport,” declared Ned, as he pulled the blankets over him, for, while the day was warm it was cool at night on the water.

“It’s the right way to spend a vacation,” agreed Bob.

“And when we get in the auto, and the airship, we’ll have more fun yet,” predicted Jerry. “I’m anxious to get to Snake Island.”

“I hope that place doesn’t get its name from the fact that it’s filled with snakes,” commented Ned, in sleepy tones. “I hate the things.”

“I hope there are a lot of the reptiles,” spoke the professor. “I may be able to get a few specimens. And I certainly do want to get that two-tailed toad.”

“And I want some radium,” added Jerry.

The next day’s trip was without incident, and by night they had crossed the lake to its outlet, down which they expected to proceed for about a hundred miles.
