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.

Keeping well down in the grass, I managed to peep through a tree, and there saw a fine reitbok looking after us. He stood up for about a minute as if he were watching to see if we had really gone away, when, seeming to think everything safe, he laid himself down again. I reported what I had seen to my impatient companion, and proposed that we should make a long round, and come upon the buck from the opposite side. We, therefore, left our horses, and crossed the ravine between the two hills on foot, taking care to keep well out of sight. I drew my charge of shot and loaded, so as to have a bullet in each barrel; my friend preferring two heavy doses of buckshot. All being in readiness, we approached the ground that I had marked as the reitbok’s lair, and were within fifty yards of it, when the buck got the alarm and bounded off. I had only a snap shot at him, my friend fired at the same instant, and the buck fell. We ran up, and, to the evident disappointment of one of the party, found that the buck had been killed by a bullet-wound which had passed close to the backbone. There was not a single shot-hole in him besides this one; there could be no mistake, therefore, about the arm which delivered the death-wound. We brought the horses to the spot, mounted the dead buck on my pony, and then took up a fresh line of country in hopes of finding another buck. We went some distance with no luck, when my dog flushed a covey of red-winged partridges. We dismounted, and walked about beating the bushes, when I suddenly noticed that he was pointing at a small clump of bush; he did not stand as though it were a bird, but occasionally drew his head back quickly. I called him away, fearing it might be a poisonous snake or a leopard, and, approaching the bush with caution, peeped through the branches, and saw the thick body of an enormous boa-constrictor moving very slowly away. I instantly sent a bullet through the part of the body that I saw, and sprang back, when the bushes were violently shaken as though the constrictor thought this sudden attack was anything but satisfactory. I now loaded the discharged barrel with a heavy dose of buckshot, and advanced to the bush. Holding my gun out at arm’s length, I pushed the branches gently on one side to get a peep at my antagonist and see how he liked what I had done. The snake was very artful, and waited quite quietly until I stooped a little to get a better view, when he darted out his head, making a sort of lunge at me; he opened his tremendous jaws as he came, and then suddenly drew back. I stepped away quickly to avoid this attack, and gave the boa my charge of buckshot between the eyes before he got out of sight. Turning his head round, he seized his body with his fangs, gave a wriggle, and died.

His mode of attack gave me an insight into the method by which this species of snake destroys animals. The teeth of boa-constrictors being long, bent, and turned back, something in the fish-hook shape, the snakes dart out in the manner I have just described, and seize hold of their prey. Then drawing their heads back again, they pull the animal to the ground at once, and, coiling round it, commence the crushing process. This power of squeezing must be enormous. On attempting to skin this animal, the muscles inside had the appearance of strings of rope extending from the head to the tail; these he seemed to have the power of contracting or extending, so that a part that might be three feet long as he coiled himself round your body, could be instantly reduced to about a foot, by this means giving any one in his embrace a very tolerable squeeze. I have before remarked that these snakes are not considered dangerous to man, as they are not poisonous; and if those attacked had a sharp knife, and managed to keep their arms free, Mr Snake would get the worst of it. If one happened, however, to be asleep, and a boa-constrictor then became familiar, he might so have wound himself round arms and body as to prevent a knife being used. I have no doubt that they have power sufficient to crush any man to death in a very few seconds, did they once get themselves comfortably settled round his ribs; but I never heard of such a case during my residence at Natal, although I made every inquiry from the Kaffirs. Formerly there was a great deal of superstition amongst the Kaffirs with regard to this snake, and a person who killed one had to go through a quarantine of purifying; now, however, the Kaffirs do not seem to care much about them. I saw an old fellow near the Umbilo River pinning a large boa-constrictor to the ground with several assagies to prevent its wriggling; he had about a dozen different ones stuck into its body, and seemed to think a few more would do no harm. He told me that the snake was a great rascal, and had killed a calf of his some time before; that he had long watched for an opportunity of catching it out of its hole, and at last found it so, when a smart race of some yards ended in the Kaffir assagying the veal-eater.

We tried to skin the boa-constrictor that I had shot, but found great difficulty in separating the skin from the muscles, and his odour was strong and disagreeable. Whenever we put in the knife so as to touch his nerves, he made a little sort of jump that was anything but pleasant. We contented ourselves, therefore, with a piece of his skin about six inches long, which remained our only trophy. The colours of this boa were very brilliant, and they had a bloom on them like a ripe plum; he was evidently up to good living, for he had breakfasted that day on a partridge, as was shown by the post-mortem. His length was 21 feet, and circumference about 1 foot 6 inches; he must have weighed about 200 pounds.

Our bag on this day was a reitbok, a boa-constrictor, and a brace and a half of partridges. I believe that we should not have obtained either of the larger animals, had it not been for a second examination of the suspicious moving grass in the manner that I have mentioned. Had we stopped at once to look at the object, the buck would have bounded away without a moment’s notice, but as it was, he fancied he was unobserved and secure.

I give these details to show on what small hinges success in South-African sport may turn.

The Kaffirs reported that a boa-constrictor lived in some long reeds near the Umganie, and they said it was an enormous animal, and fully fifty feet long. I once saw its spoor on the sand, and judged that it must be nearly thirty feet long. On several occasions I sought interviews with it, but was unsuccessful in finding it at home. It is always better to give all snakes a wide berth, and not to go out of one’s way to destroy them, unless they have taken up their residence in or near your house, or their destruction can be accomplished with ease and safety.

Many snakes of South Africa are not poisonous: a very good plan for telling them is to notice the shape of their head; anything approaching the form of the ace-of-clubs, or a breadth across the forehead as it were, is indicative of venom; while those with the narrow lizardlike heads are harmless.
