As Jerry had said, it was a large body of water, and around its shores were many resorts where cottagers and hotel guests spent the summer months. The lake, too, was dotted with pleasure craft of many sort, but the boys did not stop to enjoy themselves as they might have done.

“We can do that on the trip back, if we want to,” said Jerry, little realizing how soon they would come back that way again, and on what an errand.

On they sped, now and then blowing their whistle three times, in response to the salute of some lake craft, the skipper of which recognized a strange boat.

“That looks like a good place to eat,” observed Bob, as they passed a large hotel, set in the midst of beautiful gardens, that came down to the water’s edge. “A fine place, all right!”

“I guess the Scud’s galley will do for the present,” rejoined Jerry. “I want to see Professor Snodgrass as soon as I can, and we’ve been longer on this trip than I calculated.”

“Speed her up!” advised Ned.

“That’s what I’m doing,” was the reply.

Hurdtown, where the professor had said he would stay, was a small settlement, about a mile from the northerly end of Lake Mogan. It was in a lonely neighborhood, and it could be reached only by boat.

There were no railroads near it, and no towns of any size. It was a hunting district, but one not very well known and, in consequence, not thickly settled.
