Tonto nodded slowly.

The Lone Ranger liked the idea. Tonto's unequaled knowledge of woodcraft and his animal-like skill in following a trail that was invisible to white men would make him a powerful ally.

Tonto told about the cattle trails he'd found beyond the top of Thunder Mountain, and the trail that led from the mountain's top to the clearing and beyond into the Basin. He told of his suspicions that stolen cattle were harbored in the Basin.

When the masked man asked where Tonto had secured the food he'd brought, the Indian evaded answering. His pride had suffered when he had been compelled to ask a girl to help him. He felt just a little bit like many of the vagrant, begging Indians that were so despised in certain parts of the country. Nothing but the urgent need of his friend would have prompted Tonto to request those favors, and he fully intended some day to wipe out the obligation. The Lone Ranger didn't press the point.

Tonto did, however, answer many questions that had bothered the masked man when he explained how he happened to find the cave. He had heard shots in the Gap, and gone toward the sound. Scrambling down a rocky side of the canyon in the dark, he had seen a white horse dimly outlined in the darkness. He hadn't suspected that the horse was Silver, but instinctively he had sounded the birdlike trill that Silver knew. When the big stallion came to Tonto's side, he saw that there was no equipment behind the saddle and assumed that Silver was alone. He had led Silver into hiding until dawn, when he followed the back trail to the scene of murder. Signs there showed that one man had gone wounded from the scene. He followed, then, the blood-marked trail until he came to the cave.

"As simple as all that," the masked man commented when Tonto finished his recital. "If I hadn't been so nearly unconscious, I'd have recognized your whistle."

The two spent most of the forenoon making plans and preparations. The masked man's wounds still bothered him, but he felt equal to a long ride and he was eager to get started on his investigation. He wore the mask continually, so it would become a familiar part of him, and not something strange that hampered his movements.

After their noon meal the two were ready, with their duffle loaded on the backs of Scout and Silver. The white horse seemed eager to be in action once again with his master in the saddle. He whinnied jubilantly when the cinch was pulled tight, and his great strength showed in every rippling muscle beneath his snow white coat.

Tonto mounted Scout, then waited. The Lone Ranger placed one foot in the stirrup and shouted, "Hi-Yo Silver!" The big horse lunged ahead. "Away-y-y," the ringing, clear voice cried as the masked man settled in the saddle. Silver was a white flame leaping ahead, with silky mane and tail blown straight out by the wind, like the plumes of a knight in white armor. Sharp hoofs hammered on the hard rocks in a tattoo that thrilled like rolling drums. Silver had his master in the saddle, Tonto close behind him. The master's voice rang out again to echo both ways in the canyon, "Hi-Yo Silver, Away-y-y-y." Tonto, watching from his saddle close behind the mighty Silver, whispered, "Now Lone Ranger ride."

A stretch of flat tableland extended for several miles between the rim of the Gap and the foot of Thunder Mountain. After the first thrilling dash, the Lone Ranger slowed Silver to let Tonto take the lead and set the route. The Indian knew exactly where to go to reach the mountain's top without passing through the Basin. The masked man was not strong enough for great activity, but Tonto anticipated none for the time being. The purpose of this trip was merely one of observation. The Indian intended to point out cattle trails he'd seen, and study them. In so doing he and the Lone Ranger would get further away from the danger of the cave's proximity to the Basin killers.
