I was equally afraid to make any farther advance—for that might be still more perilous. I had already noted the direction of the wind: it blew from the river, and towards the camp; and should I bring my horse opposite the line of the mustangs, I would then be directly to windward of them, and in danger from their keen nostrils. They would be almost certain to take up the scent of my steed, and utter their warning snorts. The breeze was light, but so much the worse. There was sufficient to carry the smell, and not enough to drown the plunging noise necessarily made by my horse moving through the water, with the occasional hollow pounding of his hoofs upon the rocks at the bottom.
If I raised my head over the bank, there was the danger of being seen; if I advanced, the prospect was one of equal peril of being scented.
For some moments I stood hesitating—uncertain as to whether I should leave my horse, or lead him a little farther. I heard noises from the camp, but they were not distinct enough to guide me.
I looked back down the river, in the hope of being able to calculate the distance I had come, and by that means decide where I was; but my observation furnished no data by which I could determine my position. With my eyes almost on a level with the surface of the water, I could not judge satisfactorily of distance.
I turned my face up-stream again, and scrutinised the parapet line of the bank.
Just then I saw an object over its edge that answered well to guide me: it was the croup and hip-bones of a horse—one of the mustangs staked near the bank. I saw neither the head nor shoulders of the animal; its hind-quarters were towards the stream; its head was to the grass—it was browsing.
The sight gratified me. The mustang was full two hundred yards above the point I had reached. I knew that its position marked the outer line of the encampment. I was in the very place where I wanted to be—about two hundred yards from the lines. Just at that distance I desired to leave my horse.
I had taken the precaution to bring with me my picket-pin—one of the essentials of the prairie traveller. It was the work of a moment to delve it into the bank. I needed not to drive it with violence: my well-trained steed never broke fastening, however slight. With him the stake was only required as a sign that he was not free to wander.
In a moment, then, he was staked; and with a “whisper” I parted from him, and kept on up-stream.
I had not waded a dozen yards farther, when I perceived a break in the line of the bank. It was a little gully that led slantingly from the level of the prairie down to the bed of the stream. Its counterpart I perceived on the opposite side. The two indicated a ford or crossing used by buffaloes, wild-horses, and other denizens of the prairie.
