[British Guiana, the land which seems so strongly inclined to extend its borders at the expense of Venezuela, is as yet very far from being the active and well-developed settlement which might be imagined from the aggressiveness of its rulers. Mr. Brown's story of it indicates a land of which nature is still largely the lord, and which is so little known that he, as late as twenty years ago, was able to discover a river and a cataract not previously heard of. The selection we append, descriptive of the wild animals of the country, is significant of an undeveloped land. Mr. Brown, in his "Canoe and Camp Life in British Guiana," describes a number of unsuccessful efforts to shoot jaguars, and continues:] One of the men happened to go a few yards behind one of our camping-places, when he heard a movement behind him; turning round he saw a jaguar leisurely surveying him. He fled to the camp with his story, and I went in search of the animal accompanied by one man armed with a cutlass. We did not go far before we saw its tracks in the sandy bed of a dry water-course, and concluded that it had gone off. We gave up all hopes of seeing it, and, turning round, were on the point of making our way back to camp, when my companion suddenly exclaimed, "Look! look! the tiger!" Glancing at the spot indicated I saw it crouching in a thicket with its head bent down, its body swaying from side to side, glaring at us with eyes of a greenish metallic hue. The brute had evidently been following us whilst we were searching for it, and was working itself into a rage. I took as good aim at its head as I could, and fired; but instead of seeing it lying dead, I heard it bounding and crashing through the forest at a fearful pace. One of my men got a shot at a jaguar on a sand-beach, where it passed within twenty feet of him, as he crouched on some rocks. The only effect the shot had on the animal was to make it gallop away a few yards, then turn for an instant and look at him. The men whom I left in charge on the New River cut open a hollow log containing young accouries, and took them out. Their squeals on being seized attracted a puma, which ran close up to the men, apparently wishing to get the accouries, when one of them fired at it and it made off.
