I am under the impression that the poisonous snakes are much troubled, at certain seasons of the year, by the poison-bladder becoming surcharged, and that thus, being anxious to rid themselves of this poison by biting something soft, and thereby pressing it out, they naturally seize the first thing which their instinct tells them will not injure their poisonous fangs. Two instances that occurred at Natal appear to bear out this theory. A Hottentot was crossing the Mooi river drift, another man following a short distance in the rear. The last man saw a snake dart out from some rocks, seize the first Hottentot by the leg, and glide back again; the bitten man died within a very short time of receiving the bite. There is at the present time a man in the Royal Arsenal at Woolwich, who, when far up the country with his master, and walking near the waggons, perceived a puff-adder spring at his face. He suddenly lowered his head, and the snake wound itself round his wide-awake hat. The man knocked the hat off, and the snake was immediately shot by a looker-on. The puff-adder always springs backwards, and can make extraordinary leaps. There is a very fine specimen now to be seen in the Zoological Gardens, Regent's Park. I have heard from both Dutchmen and Kaffirs that there is a snake which spits out its poison at any one who may approach, and makes capital shots. Blindness often follows if the victim is struck in the eyes, and a horrible disease of the skin if the face or hands are touched by the poisonous secretion. I am not aware of the appearance or name of this reptile. Besides the venomous snakes that I have mentioned as being common about Natal, there is also a species of boa-constrictor which grows to a considerable size; and although this snake is not dangerous, still it is slaughtered by man whenever met, as it is destructive to birds and small bucks. I shot six of these during my prowlings around the bush and swamps of Natal; the largest was shot when I was in company with an English gentleman who rarely went out shooting and was a prey to despair almost before he had commenced. As the whole of that day's proceedings serve to show that it is well never to give up or to throw away a chance, I will describe them in detail. We had for nearly four hours continually searched kloofs and ravines, but we had seen no game whatsoever. As we were riding over a little hill, I thought I saw something move on an opposite ridge, a little behind me and on my left hand. I would not look round, but rode steadily away until we had passed over the hill and were quite out of sight of whatever had caught my attention. I then mentioned to my companion that I fancied I had seen something more on the opposite hill, and that I purposed creeping back to have a second look. He voted for _riding_ over the hill, but this I would not hear of.
