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.
