Twice again Jack shouted his name, but as he did not turn his head she touched her pony lightly with her riding whip and rode after him. She regretted now that she had allowed the boy to get so far ahead of her, for her own few minutes' delay had naturally increased the distance between them. Yet Jack did not feel that it would be fair for her to turn back without informing her companion. It seemed almost cruel to force her jaded horse at such a pace through the loose sands; yet how else could she ever hope to catch up with her escort? Carlos did not usually show such poor judgment with his own steed.
Then finally it occurred to the girl that the Indian boy was refusing deliberately to answer her as a punishment for their trouble earlier in the day. If this were true she was foolish to waste any more time and energy in pursuit of him. She could get back home alone long before bedtime by allowing her horse to walk for a part of the way. Then if the storm should overtake her, she would not be far enough from the Lodge to have it make any serious difference. As for her scolding, well, Jack felt that she would have to accept that as philosophically as possible under the circumstances. For Jim would have a double grievance, since he did not like any one of them to ride for any distance with only Carlos as a companion.
Shrugging her shoulders, too tired really to be angry again that day, Jack called once more. This time, to her surprise, Carlos actually rose in his saddle, pointing with evident excitement toward some indeterminate objects at a little distance off. Jack could not see what they were, although she guessed at once. After all, their hard day's work had not been in vain! Carlos had assuredly discovered the lost stock. True they must have wandered beyond the confines of the Rainbow ranch, since Jack was familiar enough with their own boundary line to know that Carlos was even at this instant passing beyond the wire fence which circumscribed it.
Their stock oftentimes got outside the ranch by mysterious methods of their own. Therefore if Carlos believed that he saw the mares they had been searching for the entire day, it would be foolish to turn back without them. It was unfortunate that the heavy cloud in the west seemed to be driving toward them with so much greater speed in these last fifteen minutes. Still if it should reach their vicinity before they could get the lost mares and colts into some kind of shelter the animals must perish. For the mares would never desert their young and the colts could never endure the force of the wind and the great blankets of sand that would probably sweep over and cover them.
