“How far up is it?” asked Clay.
“Something like two thousand feet.”
“Almost to the surface?”
“Not half way,” was the laughing reply. “There was a copper mine there, once, years ago, and the shack was left by the miners when the drive was deserted. It is an uncanny place!”
“How do you get there?” asked Alex. “Is it a hard climb?”
“Rather! In places the path is only thirty inches wide, with a wall a thousand feet up on one side and a drop of a thousand feet on the other! In places the way is so steep that steps have been cut in the rock, to prevent the burros slipping.”
“Burros!” echoed Alex. Walking up and down that wall!”
“Both burros and horses, after proper training,” Don answered.
“I think I'd rather walk!” Alex muttered, and Case nodded agreement.
“You’ll find that horses’ feet are surer than your own,” Don predicted. “There is rarely an accident here.”
