“Suppose, though, we run against it. What shall we do then?” asked Leo.

“We must jump out and haul the boat up,” answered Natty. “The shore is not dangerous like that of the sea-coast, and we shall have no great difficulty in saving ourselves, even if we are driven on it.”

“We need not talk of such a contingency,” I remarked. “I hope we may keep clear of all dangers till the gale drops, or till daylight returns.”

Though I said this, I could not help feeling very anxious, particularly at the thought of being driven so far from home, for I knew that Kate would become alarmed should we not return at the time we proposed. Still we kept on; but often as I bent my head forward, trying to make out any object ahead, nothing could I see but the curling waves as before. I had no idea that the lake was so long, and expected every minute to find that we were approaching the end of it. Still on and on we went. Hour after hour passed by, and I calculated that morning must be approaching. The gale still increased, and as the light canoe flew over the foaming seas I dreaded every instant that they would break on board. She behaved beautifully, however, and though occasionally the top of a wave tumbled over her, we took in no great amount of water. At length, as I cast my eye towards the east, a faint light appeared in the sky. I hailed it as the harbinger of morning. At the same time the wind began to fall, and in a few minutes had evidently greatly decreased. I began to hope that our dangers were coming to an end, and that we should only have the trouble of paddling back again without visiting our Kabomba friends.

“I see the shore!” cried Leo, “on my right hand.”

“And I see it on the left!” exclaimed Natty.

Just then Mango, who had been sitting quiet at the bottom of the canoe, lifted up his head as if listening, and then pointed to the south evidently in a state of alarm. He uttered a few words, but what he meant to say I could not make out. There was still so much sea that I was afraid of hauling the boat up: to attempt to reach the north shore. I therefore stood on as before, and in a short time found that we were entering either a narrow part of the lake or the commencement of a river flowing out of it, and I hoped every instant to reach some point where we could safely land. We had stood on some little way further, when I began to suspect, by the rapid way we passed the land, that we must have a strong current with us as well as the wind. Scarcely had I made this discovery when the loud roar of waters reached my ears. It was the deep, solemn sound which proceeds from a cataract. Now for the first time the truth broke on me. We were in a rapid current, which was hastily hurrying us on towards a waterfall. Not a moment was to be lost. I told the boys to lower the sail and to endeavour to get the canoe’s head round so as to pull in for the shore; for as to making any way against the current and the wind combined, that I knew was impossible. They did their utmost, I helping them with my steering paddle, and Mango working away with a spare one; but still so heavy were the waves that they threatened every instant to capsize us, and I saw that we were being carried down almost as rapidly as before. In vain we paddled. We appeared to make no way. “Hope for the best, hope for the best!” cried Natty, exerting himself to the utmost. The perilous position in which we were placed pressed heavily on my mind. The loud roar of the cataract sounded louder and louder, and as daylight increased I made out in the distance a cloud of spray rising in the air. Down it there appeared every probability we should be carried, and what hope was there then of our escaping with life? I looked anxiously round on every side, and at length the increasing light revealed a small island a little way further down the stream. I trusted that by our exertions we might reach it. We continued straining every nerve. Rapidly the canoe was borne down sideways towards it. “A few strokes more and we shall be there,” I cried out. “Work away, boys, work away.” In spite of our exertions down glided the canoe, and the end of the island was passed. Still, we might reach some part of the side of the island. Had I been alone I might almost have leaped on shore. The moment was a fearfully anxious one. I could distinguish the southern end of the island. If we failed to reach that we must be lost. Trees overhung the banks. I gave a few more desperate strokes, and drove the canoe forward till her bows just touched the shore. “Leap out!” I cried. The canoe swung round. Natty seized the branch of a tree which hung down close to him, and swung himself up. I thought Leo and Mango had done the same, for I saw Leo clinging to a branch of a tree, and the black springing with the painter in his hand towards the shore. I therefore, seizing my gun and ammunition, leaped to the bank. What was my horror the next instant to see Leo fall back into the boat, the branch he had caught hold of breaking, and the black boy still holding on to the painter floating after the canoe. Leo seemed scarcely conscious of his own danger, but rushing to Mango, assisted to drag him in. My impulse was to spring into the water and try to regain the canoe, but just then Natty’s voice reached me, crying, “Oh, help me, Andrew! help me!” and I saw that, though clinging to a branch, he could not manage, laden as he was, to climb along it so as to gain the shore in safety. I hurried to assist him, my heart sinking at the thought of what would become of Leo and Mango. I clambered along the tree, and at length got hold of Natty, but it required some caution to prevent us both falling off into the water. I got him, however, safe on shore, and then we hurried together to the south point, anxiously looking for the canoe. Leo and his companion had got out their paddles, and were working away in what appeared an utterly vain attempt to reach the north bank before the canoe would be hurried down the cataract. Natty wrung his hands in despair.

“Oh, how could it have happened?” he exclaimed, “I would have done anything rather than let Leo go. What is to be done? what is to be done?”

I had no consolation to offer him. Still the increasing light showed me that there were other islands intervening between the falls and the one we were on. It was barely possible, however, that the canoe would drift against one of them. We stood watching them with the deepest anxiety as the canoe was carried further and further down the current. Already she appeared to be in the rapids, from her quicker movement; and gliding faster and faster away, she soon was almost out of sight. It must be understood that there was a considerable distance between us and the cloud of vapour which I supposed to mark the situation of the fall. At length the canoe was hid from us altogether by a tree-covered island; but whether Leo and his companion had managed to reach it or not we were left in fearful doubt. It was some time before I could rouse myself. Poor Natty sat down on the ground with his head resting on his hands, completely overcome.

“But perhaps, after all, they may not have been lost!” he exclaimed, starting up, “and they may manage to tow the canoe along the bank of the river and come back to us. What do you think?”
