Frank fancied that in the present case he might drop before the deer did, though he realized that Mr. Oliver's rule was in one way a merciful one and undoubtedly calculated to encourage careful shooting. When he had recovered his breath a little they started again, but it was half an hour later when they caught a glimpse of the deer painfully laboring through a clump of fern on the slope of a steep rise. Harry pitched up his rifle, and though the animal disappeared again immediately after they fired, they knew it was still going on by the snapping of twigs and the rustling in the fern. Harry was sure that he had hit it, and making a last effort, they broke into a run which Frank remembered for a considerable time afterward. The slope seemed to be getting remarkably steep, he could scarcely see a dozen yards in front of him through the undergrowth, and several times he stuck fast for a moment or two in tangled thickets. Then he fell into a horrible tangle of rotting branches, dropping his rifle and bruising himself cruelly, and he only succeeded in forcing himself along because his companion shouted breathlessly that the deer was rapidly flagging. Frank could hear it very plainly now. At last when they reached the summit of the rise it came out into open view for a moment. The bush was thinner there, with less growth between the trees, and he saw the animal limp out from a thicket, dragging an injured limb. He flung up his rifle, and Harry who was a little in front fired almost as he did. The deer staggered, made a feeble bound, and vanished as if the earth had opened under it. A moment or two later Harry stopped with a hoarse, gasping shout. Frank stumbled forward and found him standing on the brink of what seemed to be a very deep ravine, the almost precipitous sides of which were shrouded in young firs and densely growing bushes. Harry was gazing dubiously into the gully. "I don't quite know how we're going to get down, but we'll have to try," he said. "The deer's at the bottom done for, and I don't feel like going home and telling dad we left it. Besides, it's quite likely he might send us back for it." "Then if it has to be done, we may as well get about it," said Frank wearily. Slinging his rifle, he crawled over the edge and went sliding and slipping down for about a dozen yards until he fell into the branches of a young fir. After that he plunged into several bushes before he could stop again, and eventually lowered himself foot by foot, clutching at whatever seemed strong enough to hold him, until he alighted knee-deep in a splashing creek. Nearby the deer lay motionless where it had fallen upon the stones. It was a beautifully symmetrical creature, but it seemed to Frank smaller than he had expected. "A young black-tail," said Harry. "Anyway, that's what we call them, though I believe it's really the mule-deer. There's another black-tail. We've got the deer names kind of mixed up on the Pacific Slope."
