ood judgment in adopting the course you did."

"See here, Harry; I don't understand this. You will remember when we
examined him, just before leaving him here, that we found only one
bullet hole between the shoulders; this has two bullet wounds, one in
the head and the other in the neck."

"Why this is not the place we shot him. This must have been shot by some
one else."

"Do you remember what you selected as your marking for the spot?"

Harry looked about, and finally said: "I remember two trees, standing
about ten feet apart, east and west of each other."

"That is the place, I am sure," was George's conclusion, after they had
made a circuit around the spot; "yes, I am sure those are the trees."

"There it is; I see it."

Surely enough, close to the two trees an animal was found, larger than
the one they had just left.

"So it seems you killed two of them," and the Professor was so much
amused he could not help laughing as he saw the amazement on the boys'
countenances. "You are certainly fine hunters."

"I think--yes; here is the shot in the shoulder--this is the last one we
shot. The other one, over there, was the one we followed so long and
took our first shot at."

Within two hours the skins were ready, packed on the skid, and delivered
at the raft, and after a hard forenoon's work the Cataract was reached
shortly after noon.

CHAPTER VI

HUNTING VEGETABLES AND PLANTS

One night, while engaged in the usual evening discussion, many topics
were mentioned, things connected with the day's adventures talked over,
and plans for the following day considered.

As usual, George was the persistent questioner, but Harry was the one to
utilize the meaning, and generally the first to take advantage in a
practical way of the information thus obtained.

We have stated heretofore that George was the theorist and Harry the
practical one. George delighted to delve down into mysteries; but Harry
utilized the knowledge in constructing and building articles. Both,
therefore, had useful accomplishments. To learn and to do are the great
things in life.

During the day the boys had turned out a nice sample of bread, and
George, as usual, began the questioning:

"Professor, you said the other day, that fermentation caused a change in
the dough, and that it was due to heat. I am curious to know why heat
should cause it to ferment?"

"Heat develops bacteria, a tiny germ, which grows so rapidly in a short
tim
