After this our journey was enlivened by all sorts of horrible accounts of adventures with caymans, till we neared the spot where we expected to find some buffaloes.  As we rode along we heard an extraordinary cry. "It is a wild boar," exclaimed our friend; "but I suspect a boa has got hold of him--a great _bore_ for him, I suspect."  We rode to the spot whence the sound came.  There, sure enough, suspended from the low branch of a tree was a huge boa-constrictor, some twenty feet long, perhaps, which had just enclosed a wild pig in its monstrous folds. While we looked he descended, and lubricating the animal with the saliva from his mouth, and placing himself before it, took the snout in his jaws and began to suck it in.  We had not time to wait, as our friend told us it would take a couple of hours before he got the morsel into his stomach.  This process is performed by wonderful muscular action and power of distension.
