"Then join your father as soon as you can. Don't try any fool stunt like going into the mountains. Remember, when you are on the prairie you can sec on all sides of you." "Except when you're behind a crest," chuckled Tom. At this reference to the recent contretemps Jeffreys frowned, started to say something and instead dug his spurs into his pony, galloping away without even so much as looking back. "He's a fine neighbor--not," declared Larry as the trio resumed their way. "I should have thought he would be only too glad to help your father and Mr. Snider get back their cattle." "He isn't very keen for the Half-Moon," rejoined Horace. "Father beat him in a law case over a boundary line once and he's never forgotten it." "And I reckon he won't forget his meeting with us to-day," said Tom, grinning. At the memory of the reception they had given, Jeffreys the comrades had a hearty laugh. "Still, he gave us some good advice," asserted Larry. "I agree with him that the thing for us is to find the Half-Moon and Three Stars crowd as soon as we can." "Which seems to be a pretty big order in itself," mused Tom. "I say we go and see where they drove the cattle into the hills and then decide." This suggestion met with no opposition, and as the boys rode toward the mountains, the wooded sides of which looked inviting because of the relief they promised from the torrid heat of the plains, they discussed various plans, only to discard them. At last they reached the hills. Dismounting, they hobbled their ponies, removed the saddles and bridles sticky with lather, and then broke out some lunch which they ate ravenously, despite the fact that their mouths were almost parched. Greatly refreshed by the food, the boys decided to follow the trail of the cattle till they could get some idea of its direction. "Let's go on foot," suggested Tom. "The ponies will be all right, the rest will do them good, and we can get through the brush and over the rocks with less noise." Readily his companions agreed, and picking up their rifles, they quickly found the tracks made by the cattle. For some distance the trail seemed more like an abandoned wood road than anything else. But gradually it began to grow narrower and at last became no more than a path winding in and out among the rocks. Several times some sound caused the boys to raise their guns to their shoulders and peer about in all directions, but nothing could they see save the trees and rocks, and they ascribed the noises to some denizen of the forest roaming about. Of a sudden Tom, who was in the lead, stopped. "I smell something awful queer," he whispered. The trail wound along the edge of a sharp descent and just ahead was an abrupt turn. Ere either Larry or Horace could reply to their companion's announcement all three were dumb-founded to see a big, shaggy brown head appear round the turn in the trail. "It's a bear!" gasped Horace.
