"But we are mighty lucky to get off so easily," said Dick. "I wonder how old Hacky has fared."

"I hope he's all right. Say, my head spins like a top. Here come the rest of the fellows. I'll bet they are scared."

Both boys rose slowly and painfully to their feet. They were much jarred and bruised, but, fortunately, no serious damage had resulted.

"Hello, Hacky!" yelled Bob.

An answering hail came from below.

"He must be all right," said Dick, joyfully. "There he is—away down at the bottom of the hill."

"Are you hurt, fellows?" came a cry.

The other boys were making their way down the smooth, treacherous surface as fast as they dared.

"Not a bit of it!" yelled Bob. "Let's see about Hackett."

Without waiting for the others, he started down the incline, this time in an orderly fashion. Dick Travers followed him.
