"Well, if you don't take the cake for seeing the wrong side of everything," Lil Artha told him. "Of course there's a cabin, and we must be getting close to it as we stand now. About the old gentleman making a blunder, and wandering off, don't you know we've been following his out track all the while. And say, what's that you can glimpse through this little opening in the woods—in a direct line with these two birch trees, tell me that now, George, you old humbug of a grumbler?"

Thereupon George, only too willing to be convinced, took a long look, and then slowly admitted that he might have been too hasty.

"It does look a little like a shack roof, Lil Artha, and p'raps I hadn't ought to have spoken like I did; but even now that may be a fooler. Just wait and let's make sure before we holler."

In another five minutes all doubt with regard to this was ready to vanish even from that wavering mind of George, because they could plainly see one end of what seemed to be a pretty substantial log cabin, with a broad chimney running up the back, fashioned of slabs, and hardened mud that no doubt resembled flint.

It seemed to be an ideal snug retreat for a man who wanted to get away from the world, and enjoy himself after his own fancy. Here Uncle Caleb had come for years, and his visits to the haunts of civilization had been few and far between. As time passed on they threatened to cease altogether, for he found more real happiness here than he could among mankind, struggling constantly in pursuit of the mighty dollar, and pushing others down in trying to climb.

"How do you like the looks of it?" asked the owner of the cabin, with a touch of pardonable pride in his voice; for he had gone to considerable trouble in order to make the place attractive; and even though mounds of snow covered everything around, the boys could see that he had some conveniences, such as ordinary loggers' camps could hardly boast.

"It strikes me as a pretty sight," Elmer candidly admitted; "and I don't blame you, sir, for keeping up here. I should think you'd feel lonesome sometimes, though?"

"I do, and used to have a friend spend part of the season with me," acknowledged the scientist; "but last fall he married, and went to Europe, so that up to now I've been all alone, and your coming will be doubly welcome as a break in the monotony of the thing."

"But, Uncle, if as you say you are alone, who could that have been I just saw at that little window?" asked Toby.

"I certainly saw something moving inside there, too," Lil Artha asserted, beginning to display something of excitement, as he waited for the other to explain what already began to take on some of the elements of a dark mystery.
