I rode for about three hours in this labyrinth, passing from one buffalo path to another, until the ground began to grow more uneven, and here and there large masses of rock rose between the trees. I dismounted, and was leading my horse up a narrow path by the side of a great boulder, when I suddenly saw, on raising my head, the entire forest literally covered with wild cattle. I returned to the rock, as a meeting with these most dangerous animals on an impracticable path like this was not desirable, and hanging the bridle over a branch, I again ascended the height in order to convince myself in what direction the cattle were going. The herd passed me bound westward, and I am certain I saw over 300 head pass. These denizens of the desert are the most savage and dangerous animals in Western America. Like the horses of the first Spanish settlements they are runaways, and have now entirely returned to a state of nature. You never see a spotted or black head among them: they are all chestnut with black extremities, and a yellow stripe down the back, and are more lightly and gracefully built than our cattle, and as rapid as deer. They shun man, but when startled or excited, they attack with the most frightful courage and obstinacy, and I would sooner defend myself on foot with a bowie knife against a black bear than with a rifle against a furious bull of this description. I remained for about an hour behind the rock before the last of the herd had disappeared between the trees, after which I rode across their deeply trampled path, and soon found myself on the edge of the forest. From this point gradually rose a bald desolate mountain range that ran from east to west, and whose base was covered with bad grass and a few scattered granitic rocks. These mountains, the San Saba, are spurs of the Rocky Mountains, which I had already noticed from the elevation, where the granite follows on the limestone. I might calculate on wandering about there for weeks before again reaching watered valleys. Hence I resolved to alter my course and go farther east, until I reached the mountains which were the source of all the streams I had lately crossed, and return home along their base.
