I was immensely interested with the way they got through the wire fences. A mule-deer is a great jumper; I have known them to clear with ease high timber corral fences surrounding hayricks. If the animals had chosen, they could have jumped any of the wire fences I saw; yet never in a single instance did I see one of them so jump a fence, nor did I ever find in the tell-tale snow tracks which indicated their having done so. They paid no heed whatever to the fences, so far as I could see, and went through them at will; but they always got between the wires, or went under the lowest wire. The dexterity with which they did this was extraordinary. When alarmed they would run full speed toward a wire fence, would pass through it, often hardly altering their stride, and never making any marks in the snow which looked as though they had crawled. Twice I saw bands thus go through a wire fence, once at speed, the other time when they were not alarmed. On both occasions they were too far off to allow me to see exactly their mode of procedure, but on examining the snow where they had passed, there was not the slightest mark of their bodies, and the alteration in their gait, as shown by the footprints, was hardly perceptible. In one instance, however, where I scared a young buck which ran over a hill and through a wire fence on the other side, I found one of his antlers lying beside the fence, it having evidently been knocked off by the wire. Their antlers were getting very loose, and toward the end of our stay they had begun to shed them.
