The moment this thought occurred to him, Tad began to yell at the top of his voice.
Suddenly from out the thick veil of smoke burst a pony with a mighty snort, coming on in bounds, each one of which cleared many feet of ground. On the pony's back was Stacy Brown, hatless, coatless, his hair standing up in the breeze, his face as red as if it had come in actual contact with the flames.
"Yeow!" he roared, as his pony shot past Tad as if the latter's mount were standing still. Where Stacy had come from, how he had passed through that wall of flame, Tad had not the slightest idea.
As a matter of fact the explanation was simple enough. The guide had sent Chunky out to assist Tad in bringing in the rip-rapping material. Stacy had made a detour from the camp, having gotten just inside the danger zone when the fire broke out. Guided by the butte where he knew his companion must be, Stacy headed for that point. There he came upon Tad's trail, and began yelling to attract his attention. He had heard Tad's answering cry, and this inspired the fat boy to renewed efforts.
Stacy, now that he had passed Tad, slowed up ever so little. He had passed his companion so swiftly that he was unable to determine whether or not Tad were in distress.
The latter came up, overhauling Stacy in a few moments. Both ponies were steaming from the terrific gruelling they were giving themselves.
"What you doing here?" exploded Tad.
