He has to travel fast for his own safety.
Tom and Greg, you get behind and push the wagon up the slope.
We'll all help in turn.

But hustle!" The crest of the rise of ground being made, the boys found themselves entering another forest.

Dick here found the ground as favorable to his purpose as he had hoped it would be, for on the further side the land sloped downward again, and was well-wooded.
"Drive in there!" called Prescott, pointing, then ran ahead to find the best spot for pitching the tent.
"Whoa!" yelled Prescott, when he had reached the spot that he judged would do best for camp purposes.

"Now, Dave, go over to the other side of the horse! Help me to get him out of the shafts.
The poor animal must be our first consideration, for he can't help himself.

The rest of you unload all the stuff from the wagon as fast as you can move." Slipping the harness from the horse, Dick fastened a halter securely, then ran the horse down into a little gully where the animal would be best protected from the force of the wind that would come with the storm.
Driving a long iron stake into the ground, Dick tethered the animal securely.
