Perhaps I had been watching for half an hour, when from somewhere, in the rock-slide surely, though I could not tell, there sounded a shrill bleating whistle, not unlike the whistles of the ground squirrels and marmots that I had heard all through the mountains, yet more tremulous and not so piercing. I waited. Presently a little gray form crept over a stone, stopped and whistled, then disappeared. It was my cony! If you can think of Molly Cottontail turned into the shape of a guinea-pig about eight inches long, with positively no tail at all, and with big round broad ears, and with all four legs of equal length so that the creature walks instead of hopping,--if you can imagine such a rabbit,--you will get a pretty clear picture of the cony, or pika, or “little chief hare.” I kept as still as the stones. Presently the plaintive, bleating whistle sounded from nowhere again--behind me, beyond me, up the slide or down, I could not tell. The rocks were rough, rusty chunks two or three feet long, piled helter-skelter without form or order, so that any one spot in the slide looked precisely like every other spot. I could not tell just the piece the cony had crossed, once my eyes were off of it, nor into which of the cracks he had disappeared. I could only sit still and wait till I caught him moving, so completely did his color blend with the rusty brown tone of the slide. All the while the shrill, piteous call kept coming from anywhere in the slide. But it was not the call of several voices, not a colony whistling at once. The conies live in colonies, but, judging from the single small haycock which they had curing in the sun, I think there could not have been more than two or three pairs of them in this particular slide. Possibly there was only the single pair, one of which had been shot, for presently, when my eyes grew sharp enough to pick the little creature out against the rocks, I found that one was doing all the calling, and that for some reason he was greatly disturbed. Now he would stop on a slab and whistle, then dive into some long passage under the stones, to reappear several feet or yards away. Here he would pause to listen, and, hearing nothing, would call again, waiting for an answer to his tremulous cry which did not come. Under and over the stones, up and down the slide, now close to me, now on the extreme opposite edge of the pile he traveled, nervously, anxiously looking for something--for some _one_, I truly think; and my heart smote me when I thought it might be for the dead mate whose little bare foot-pads had left the bloody print upon the rock. Up and down, in and out, he ran, calling, calling, calling, but getting no answer back. He was the only one that showed himself, the only live one I have ever seen, but this one I followed, as he went searching and crying over the steep rock-slide, with my eye and with the field-glasses, until long past noon--with a whole camp down the cañon looking for me!
