There is one main range of hills, nearly two thousand feet in height, and composed of quartz rock, the rugged and barren crests of which gave us some trouble to cross. In the evening we came across a small herd. Then dropping his hat to mark the spot where the balls were left, while at full gallop, he uncoiled his lazo, and after a most severe chase, again came up to the cow, and caught her round the horns. Jago had some difficulty in killing the furious beast. But when on level ground it does not appear an easy job for one man to kill a beast mad with terror. This horse, however, was a young one, and would not stand still, but gave in to the cow as she struggled. Jago dodged behind the beast, till at last he contrived to give the fatal touch to the main tendon of the hind leg after which, without much difficulty, he drove his knife into the head of the spinal marrow, and the cow dropped as if struck by lightning. He cut off pieces of flesh with the skin to it, but without any bones, sufficient for our expedition. This is as superior to common beef as venison is to mutton. A large circular piece taken from the back is roasted on the embers with the hide downwards and is the form of a saucer, so that none of the gravy is lost. From the great number of cows which have been killed, there is a large proportion of bulls. These wander about single, or two and three together, and are very savage. It was very interesting to see how art completely mastered force. During our whole ride we saw only one troop of wild horses. It is a curious fact, that the horses have never left the eastern end of the island, although there is no natural boundary to prevent them from roaming, and that part of the island is not more tempting than the rest. Sulivan has taken much pains for me in this inquiry. Sulivan that he had watched a stallion for a whole hour, violently kicking and biting a mare till he forced her to leave her foal to its fate. Sulivan can so far corroborate this curious account, that he has several times found young foals dead, whereas he has never found a dead calf. Moreover, the dead bodies of fullgrown horses are more frequently found, as if more subject to disease or accidents, than those of the cattle.
