At nightfall we reached Turkey Creek, as I had christened it from the great number of those birds I found here. It was still light enough to choose a good spot for our bivouac, where we were near water; we were tolerably hidden, and had very good grass for our cattle. This evening, however, Czar was hobbled, that is to say, a short line round his neck was hooked to a padded ring he always wore on his near forefoot, so that he was obliged to keep his head to the ground or his foot in the air, and hence could only walk. This was an invention of my own, suggested by the fear of losing my horse, and when fastened in this way, he could not be unexpectedly scared and driven off. I prefer it to binding the two feet, for this often lames a horse, and to tying it up with a lasso, because the horse can easily entangle its feet in the latter and be seriously injured. In this manner I could leap from my horse in the most dangerous neighbourhood, and renders it in an instant incapable of bolting. Lizzy was again picketed, and we kept a watchful eye on the animals during the two hours they were grazing; for I had nearly reached the end of my _terra cognita_ and the border of regions which had never yet been visited by Pale-faces. Ere we went to sleep, the logs were covered with ashes, the cattle fastened to trees close to us, and we lay down to rest after supper, but I could not sleep so soundly as when I had Trusty by my side; the slightest sound disturbed me, and it was always a long time ere I fell asleep again. About midnight I started up and fancied I had been dreaming about a storm; I looked up and saw that all the stars had disappeared; at the same moment the surrounding landscape was lit up by a flash of lightning, and a violent thunder-clap rolled down the valley. I sprang up, blew the fire into a flame, laid wood on it, and woke the snoring naturalist, who asked, in great alarm, about the cause of being disturbed. I advised him to do as I did, then broke off an armfull of bushes, laid them in a heap, put my pistols and bags on it with the saddle over them, covered them with the horse-rug, and laid the jaguar skin over all; after which I helped Kreger to put his traps in safety, in which he greatly missed the buffalo hide.
