little fretfully,
"but so far without meeting any success that you could notice. But what
ought we to do about it, Frank?"

"Go on, and take a wide sweep around," came the steady reply. "Perhaps
we might run across another leading clue, and then this one would look
foolish. We'd be sorry then, that we thought so bad of Todd. Perhaps,
after all, he was only making signals to one of the men connected with
the logging camp, up on the Point for something or other."

He allowed the motor to work at the reduced speed that it had been
carrying on ever since quitting the home field, where the workshop and
the hangar stood. Andy still continued to use the glasses, as though he
had not quite given up all hope of making some sort of discovery.

Once, however, they had left the northern end of the lovely lake behind
them for good, and only the forest lay below, Frank quickened matters
somewhat. Truth to tell, he hardly knew what to think, and whether what
they had witnessed could really have any bearing on the solution of the
puzzle or not.

Certainly if the hunt was only kept up in automobiles, that required
fairly decent roads to allow of their getting along, there was not much
chance of the authorities ever discovering the concealed hobo thieves;
for they could not get within a mile of the shore up there at Norton's
Point by such methods. The only way it could be reached was by boat; or
possibly through the means of an aeroplane, such as the Bird boys were
now using. Few places but could be spied upon, when one had the means
for passing over the most inaccessible thickets and rocky hills.

After a time they had gone many miles. Occasionally a small hamlet was
seen below; and then would come once more the woods that extended over
such a large space of territory in this part of the country. This was
generally because of the swampy nature of the ground, which prevented
farming operations being carried on, while the difficulty of getting the
logs out of the bogs had deterred lumbering thus far.

Andy had done his part of the work faithfully. He had scoured the
territory over which they passed, and never did a break occur, however
small, but he clapped his eyes upon it, and examined the open space
thoroughly.

"There's Rockford ahead, and we've passed over the whole stretch of
swamp and forest. Suppose, now, we dropped down on the commons, and get
Bloomsbury on the long distance phone; perhaps they might have some news
