Here, in an environment strange to their race, but peculiarly adaptable, they thrived and multiplied. The hybrid of the Galloway cow and buffalo proved a great success. Jones called the new species "Cattalo." The cattalo took the hardiness of the buffalo, and never required artificial food or shelter. He would face the desert storm or blizzard and stand stock still in his tracks until the weather cleared. He became quite domestic, could be easily handled, and grew exceedingly fat on very little provender. The folds of his stomach were so numerous that they digested even the hardest and flintiest of corn. He had fourteen ribs on each side, while domestic cattle had only thirteen; thus he could endure rougher work and longer journeys to water. His fur was so dense and glossy that it equaled that of the unplucked beaver or otter, and was fully as valuable as the buffalo robe. And not to be overlooked by any means was the fact that his meat was delicious. Jones had to hear every detail of all that had happened since his absence in the East, and he was particularly inquisitive to learn all about the twenty cattalo calves. He called different buffalo by name; and designated the calves by descriptive terms, such as "Whiteface" and "Crosspatch." He almost forgot to eat, and kept Frank too busy to get anything into his own mouth. After supper he calmed down. "How about your other man—Mr. Wallace, I think you said?" asked Frank. "We expected to meet him at Grand Cañon Station, and then at Flagstaff. But he didn't show up. Either he backed out or missed us. I'm sorry; for when we get up on Buckskin, among the wild horses and cougars, we'll be likely to need him." "I reckon you'll need me, as well as Jim," said Frank dryly, with a twinkle in his eye. "The buffs are in good shape an' can get along without me for a while." "That'll be fine. How about cougar sign on the mountain?" "Plenty. I've got two spotted near Clark Spring. Comin' over two weeks ago I tracked them in the snow along the trail for miles. We'll ooze over that way, as it's goin' toward the Siwash. The Siwash breaks of the Cañon—there's the place for lions. I met a wild-horse wrangler not long back, an' he was tellin' me about Old Tom an' the colts he'd killed this winter." Naturally, I here expressed a desire to know more of Old Tom.
