XXI. THE LITTLE OLD MAN OF ECHO CAVE 184 XXII. TURNING THE TABLES--CONCLUSION 195 THE SADDLE BOYS IN THE GRAND CANYON CHAPTER I THE WORK OF THE WOLF PACK "Hold up, Bob!" "Any signs of the lame yearling, Frank?" "Well, there seems to be something over yonder to the west; but the sage crops up, and interferes a little with my view." "Here, take the field glasses and look; while I cinch my saddle girth, which has loosened again." Frank Haywood adjusted the glasses to his eye. Then, rising in his saddle, he gazed long and earnestly in the direction he had indicated. Meanwhile his companion, also a lad, a native of Kentucky, and answering to the name of Bob Archer, busied himself about the band of his saddle, having leaped to the ground. Frank was the only son of a rancher and mine owner, Colonel Leonidas Haywood, who was a man of some wealth. Frank had blue eyes, and tawny-colored hair; and, since much of his life had been spent on the plains among the cattle men, he knew considerable about the ways of cowboys and hunters, though always ready to pick up information from veterans of the trail. Bob had come to the far Southwest as a tenderfoot; but, being quick to learn, he hoped to graduate from that class after a while. Having always been fond of outdoor sports in his Kentucky home, he was, at least, no greenhorn. When he came to the new country where his father was interested with Frank's in mining ventures, Bob had brought his favorite Kentucky horse, a coal-black stallion known as "Domino," and which vied with Frank's native "Buckskin" in good qualities. These two lads were so much abroad on horseback that they had become known as the "Saddle Boys." They loved nothing better than to ride the plains, mounted on their pet steeds, and go almost everywhere the passing whim tempted them. Of course, in that wonderland there was always a chance for adventure when one did much wandering; and that Frank and Bob saw their share of excitement can be readily understood. Some of the strange things that happened to them have already been narrated in the first volume of this series, "The Saddle Boys of the Rockies, Or, Lost on Thunder Mountain," and which, in a way, is an introduction to the present story. In the first book the boys cleared up a wonderful mystery concerning a great cavern. For several minutes Bob was busily engaged with the saddle girth that had been giving him considerable trouble on this gallop. "There," he remarked, finally, throwing down the flap as though satisfied with his work. "I reckon I've got it fixed now so that it will hold through the day; but I need a new girth, and when we pull up again at Circle Ranch I'll see about getting it. Oh! did you make out anything with the glasses, Frank?"
