continue the practice.

"I should like to go over to Observation Hill and see the flag you
made," said Ralph. All agreed to this heartily, and the merry party set
out, after being fully equipped, as was always the custom. Red Angel
formed one of the party, of course, and in lieu of a gun, George had
made a stick in imitation of one. He was immensely proud of this
acquisition, and actually hugged it when it was presented to him. From
that time forward it was his constant companion.

When the Hill was reached, Angel made for the pole, and with his gun in
hand, scrambled to the top, giving out his peculiar chuckling noise,
which indicated delight.

"Why the gun doesn't seem to make any difference in his climbing,"
exclaimed Tom.

They scanned the broad sea, and who shall say what their thoughts were
as they silently stood there. For some reason when they started to go
down the hill they were not so jolly as when going up. Their course was
directed to the east, but just why no one knew. It seemed as though they
were simply drifting, each with his own thoughts; but Harry soon
banished their reveries.

"Let us follow the beach down to South River," he suddenly exclaimed,
and all were glad that something had been said or suggested. It was so
easy to turn them from gravity to cheerfulness, and probably Harry was
trying some of the Professor's medicine on the boys.

At every step of the way, and in every action, the boys now realized
that the work of the Professor had been imprinted on them. Tom and Ralph
went along glancing superficially at the various objects, but it was
entirely different with Harry and George. Every depression, and each
succeeding elevation, or clump of trees, or any object beyond the
ordinary, was closely scrutinized by them.

This course soon became noticeable to the boys, and called forth a
comment from Tom. "Yes, we are always hunting for something. That was a
trait which the dear old Professor taught us, and it would surprise you
to know how many things we found out by that quality. We have always
since found it a pleasure in doing so."

Ralph reflected a moment, and he replied: "I can now see where we made
many mistakes during the past year by not adopting that plan."

They passed to the east around the bend, and then followed the small
bay which indented the shore, and finally moved out along the peninsula,
which terminated in a cape east of the mouth of South River.

"I have often thought
