“I have thought of forming a reed raft, on which we can ferry ourselves across the narrowest part of the stream towards the north shore.”

“But surely the current will carry us down?” he observed justly.

“I have thought of that; we must wait till a strong wind blows up the river, and then I have hopes that it will keep back the waters of the lake and probably greatly lessen the current. If so, and we can manufacture a mat sail, I think we shall be able to reach the nearest bank. It is dangerous, I grant, but I see no other way.”

“Nor do I, indeed,” he said; “but, by-the-by, I left our eggs near the river, and probably the mother crocodile will come to look for them and carry them off.”

Without waiting for my reply he climbed down the tree, and was soon back again with our provisions. “I think I saw a snout just coming out of the water,” he remarked; “and a minute later the creature would have got hold of them, I fancy. I did not stop to look a second time, however, for I was afraid that it would have caught me had I delayed.”

“I am very glad you have brought the eggs, and still more that you escaped the monster. It is evident that we must be careful not to stand carelessly by the side of the bank, or go into the water,” I answered. We were silent for some time.

“I think we should have prayers,” I heard Natty observe. “Will you say them, Andrew?”

“Gladly,” I replied; and to the best of my power I offered up a prayer for protection before we lay down to sleep. I was soon in the land of dreams, for I was thoroughly tired with the exertion I had gone through during the previous day. I was awaked by feeling Natty touch my arm.

“Look down there, Andrew,” he whispered. “See! it is just as well we are safe up in the tree!”

As I cast my eyes down on the ground below us, I saw three huge crocodiles crawling slowly about; and though they generally take their food in the water, I had no doubt that they would not have objected to seize us for their suppers had they found us unprepared for resistance. It was rather difficult to go to sleep again with the knowledge that such creatures were in our vicinity. However, after watching them for a time, I felt my eyes closing, and shortly forgot all about them and everything else present. When I awoke the sun was shining through the branches of the trees. The crocodiles had disappeared, the wind was light, the sky blue, and the smooth water shone in the beams of the rising luminary of day. Voices reached my ears. A faint hope rose in my heart that they might proceed from Leo and Mango. I quickly descended the tree, and made my way to the edge of the island on the side whence they appeared to come. There I saw, at some distance, a canoe with four blacks in her, engaged in combat with a hippopotamus. One of them, standing up, was about to plunge his spear into the animal’s neck. Several more animals were standing on the nearest reed-covered bank, while the heads of others protruded from among the reeds in the distance. Here was a means of escape, if we could make the blacks hear, and they were inclined to assist us. I called to Natty, who, descending the tree, was soon by my side. We shouted with might and main, but the blacks were so eagerly engaged in attacking the hippopotamus that they did not hear us. The monster, as he received the wound in his neck, turned round and attempted to seize the canoe; but the blacks, plying the paddles quickly, got out of his way, holding him, however, by a rope attached to the spear. Spear after spear was darted into his neck; and in a short time the blacks, taking him in tow, dragged him on shore, where, in spite of his struggles, they hauled him up, and several other people hurrying down to the bank, soon despatched him with their clubs. No sooner had they done so, than they set up loud shouts, and began dancing away in frantic joy at their success. I thought this was a favourable opportunity for again trying to attract their attention. We shouted and shouted, but still they did not hear us.
