"Oh! I rather guess it's six for you and half a dozen for myself," chuckled the other lad; "because I own up there's something about Aaron's place up there that draws me more than I ought to allow. But after all we mean no harm, and besides we may not meet any one on our trip."

"Remember," added Will, with a grin, "it's only returning the old gentleman's visit of last night, you know. We want to be neighborly, of course."

There was no hurry, since they had the whole afternoon ahead of them. Will, however, urged a start because he had hopes that they might return by a long, roundabout course, and possibly pick up some interesting views on the way.

"There are some clouds passing overhead," remarked Frank, "and we may get a little thunder shower while away; so we'd better fix things here shipshape."

This was easily done, though of course they did not think to fasten the door in any way. The other two boys might get back before they did, and it would be foolish to bar them out of the cabin. Besides, what reason had they to fear any invasion from tramps up in this lonely section of country?

Once started, Will seemed very happy. Frank on his part had no great difficulty in following the dimly seen trail. From time to time he would show his companion the marks of footprints both going and coming, and which were other than those left by himself and Bluff on the preceding day.

"That proves we guessed right when we said it was old Aaron who ran against the string of your flashlight trap," Frank explained; "and I'd give a cooky to know why he was making for the cabin at the time."

"You told the housekeeper, didn't you, Frank, that we had bunked in the cabin on the point jutting out into the bay?"

"Yes, and she may have informed him," Frank mused. "Even if he's kept himself up here away from everybody for so long, buried in his books, old Aaron might have enough curiosity to walk down over this trail that he knows so well, just to take a look at us."

"If he's half as gruff as they say," suggested Will, "he may have meant to order us to vacate the ranch. Then that awful flash came and frightened it all out of him."
