rolled in their blankets, and with their
feet to the fire, were soon deep in sleep.

They were up with the dawn, and after breakfast headed towards the
deserted logging camp. They approached carefully, and when within sight
of it, waited and reconnoitered.

"Guess no one is at home or there would be a sign of smoke from the
chimney, unless whoever is living there is eating raw food. Let's take a
look at the spring," said Garry.

At the spring they found no sign of anyone having been there lately.
This was easily seen, for the ground was soft about the bubbling spring,
and would have retained a fresh print.

"All right then, now for the bunkhouse," ordered Garry.

They entered by prying loose one of the shutters and hopped inside. The
interior gave no sign of having been used for years, as the dust was
thick everywhere, and nothing could be found that looked as though it
had been touched in some time.

In an old cupboard they found a box of nails of all sizes, and this gave
Garry an idea. Cutting his bandanna handkerchiefs in strips, he doubled
them up, until he had oblong pieces about two inches in width and four
in length. Then he removed the shutter entirely, and fastened the cloth
hinges he had made to it. While the others held the shutter in place
again, he fastened the other ends of the crude hinges to the top of the
window casing. A piece of string from his pocket was utilized to hold it
tight against the bottom of the sill.

"You see, this string holds the shutter in place, and from the outside
no one would ever suspect that it had been touched. You see I've used a
window that is not in view of the shack. Now should it become necessary
for any reason to leave this place in a hurry, a sharp push will break
the strings that holds the shutter in at the bottom, and pushing out the
shutter, it's only a matter of seconds in getting out. Then you can use
your legs in getting clear of the vicinity," explained Garry.

At the opposite end of the shack, in a shutter, was pierced a peephole
that commanded a view of the door of the shack that the boys believed
was the one used by the occupant or occupants of the building.

"There, everything is set. You chaps hike, and then Dick is to return at
noon to relieve me, leaving Phil the first watch tomorrow morning,"
ordered Garry.

Garry's watch was unavailing, for when Dick came at noon he had nothing
to report. It was arranged that no one should come for Dick, but th
