Over went the horse, dangling, head downward, above the terrible chasm, while the giant held it thus by clinging to the creature's tail!

And our hero held fast to the Mexican saddle!

Frank was amazed when he found the horse was not going downward, and, being unable to see the big man, he wondered what held the animal suspended in the air.

In a moment the man above cried:

"Are you gone, boy? Are yer done fer, youngster?"

"No," replied Frank, with sudden hope. "I am hanging to the saddle. Drop a rope to me, and pull me up—quick, before the horse falls!"

"Can't do it."

"Why not?"

"I'm holdin' ther critter by ther tail, an', burn me, ef yer both won't go to ther bottom ef I leggo!"

Then the boy realized what had saved him, impossible as it seemed, and he marveled at the astonishing strength of the strange giant who had been sent to Lake Tahoe to die of consumption.
