"They are full of life," said Joe's brother. "Let them go. We'll make the fort to-night, even if they do tire the horses a bit."

On and on went the two lads, down something of a slope and then along a level stretch. The bushes grew thick upon both sides, and here and there were numerous wild flowers. At last they reached a glade rich with green grass.
Joe was slightly ahead when he came to a sudden halt.
"Back, Darry!" he cried. "Get back behind the bushes."
"What's up?" queried his cousin, as he brought his steed to a standstill.
"Buffaloes!"
"Buffaloes! Where?"
"Right around the cliff on our right. See, they are coming this way! Here's luck."
Joe was right; they had come most unexpectedly upon a herd of seven buffaloes. The shaggy beasts were all large and powerful-looking. They were not in the least alarmed, and came toward the boys at a slow but steady walk.
