Naturally, under such conditions, the forest scenery is of the wildest imaginable character, and its flora and fauna flourish unchecked in the utmost luxuriance of tropical savage life; for the country lies but a few degrees from the equator, and is far more sparsely populated than even the surrounding tropical regions of Brazil and Venezuela. Fortunately, however, for those who for any reason have occasion to traverse this wild region, there is no lack of water-ways. Several grand rivers of great breadth lead from the coast in different directions, most of them being navigable (for canoes and small boats) for great distances, leaving only comparatively short stretches of forest land to be crossed by travellers desiring to reach the open plains and hills. Of these rivers, the Essequibo is one of the finest, and it was by this route that the two friends, Elwood and Templemore, set out, under Matava's guidance, to reach their destination. From this river they branched off into one of its affluents, the Potaro, noted for its wonderful waterfall, the Kaieteur, which they visited _en route_. Here their canoes were left and exchanged for lighter ones, hired from the Ackawoi Indians, who live at a little distance above the fall; their stores and camp equipage being carried round. So far the journey had been uneventful, save for a little excitement in passing the various cataracts and rapids; but the two young men knew their way fairly well thus far, having visited the Kaieteur with Matava some years before. When, however, the journey was resumed above the Kaieteur, the route was new to them; and, among the first things they noticed, were the alligators with which the river abounded. In the Essequibo they had seen none, and not many below the fall; but from this point, as far as they ascended the river, they saw them continually. Once they had a narrow escape. They were making arrangements for camping on the bank, and were nearing the shore in the last of the canoes, when a tremendous blow and a great splash overturned the boat, and they found themselves struggling in the stream. An alligator had struck the canoe a blow with its tail and upset it. Fortunately, however, it was in shallow water; and the Indians, seeing how matters were, made a great splashing, and thus frightened away the reptile. The contents of the canoe were partly recovered, not without difficulty; but some were damaged by the water. As they proceeded up the river, the rapids and cataracts became more frequent, and the negotiation of them more difficult, till they reached a spot where further navigation was impossible, and they had to take to the forest, their stores and baggage being henceforward carried by the Indians.
