We had to exercise the greatest care, having to jump out on small rocks which stuck up in the middle of the rapid in order to arrest the almost uncontrollable speed of the canoe. Had they missed their footing while jumping on those rocks and holding the ropes attached to the canoe, the men would certainly have lost their lives, as it was out of the question to save anybody in those diabolical waters. Therefore, when you considered the terrific speed at which the canoe was travelling, and that the men must have known that a mistake in judging the distance would have meant utter destruction, you could not but admire them for their really amazing self-confidence. On many occasions, indeed, I had to do the same thing myself, but I must say I never liked it much; although I was in a better position than they were, as I am a good swimmer—not that a swimmer would have much chance in those waters.
A number of islets were seen below the rapids and whirlpool. From that point we discerned on the right bank an elongated hill, 100 ft. high. Slightly beyond, preceded by a great mass of rock, was another island 200 m. long, dividing the stream in two. Two other islands, one 700 m. long—Leda Island—the other one Medea Island, of greater length but much narrower, were disclosed behind it.
Then came another great barrier of rocks extending from south-west to north-east, and more rapids to be negotiated. A series of elongated islets and sand-banks occurred in the basin which followed, 1,300 m. wide. Beautiful sand-beaches had formed on either side of that lovely bay. The river then narrowed again to a width of 500 m., and we saw a long flat island of sand, 200 m. long and 50 m. wide, enclosed by rocks in the centre of the stream.
We continued our journey, after the usual halt for taking astronomical observations, and had before us a small hill 100 ft. high at bearings magnetic 300°.
We came to a series of most dangerous rapids with terrific whirlpools, especially after the first and second rapid. Another great barrier of rocks with huge boulders spread across the stream from south-west to north-east. An isolated hill was to be seen on the left bank where this barrier was found. A strange coffin-shaped boulder of immense size was then reached on the right side of the stream, just after we had passed a delightful sand-spit 100 m. long enclosed within a stockade of pillar-like rocks.
From this point we had 4,000 m. of clear navigation to 280° b.m. It seemed heavenly to us to be in smooth waters again, and my men flattered themselves that we had now come to the end of the rapids altogether. But we soon arrived at innumerable rocks in a confused mass right across the stream, between which the river flowed with great force in a contracted neck. We passed between two islands, each 200 m. long, at the end of which was a rapid. An island 1,000 m. long was there formed—Bomfin Island. Dangerous rapids occurred half-way down its length on the right; then followed a mass of square columnar pillars of rock not unlike basalt. That was all very beautiful to look at, but we had endless trouble in extricating our canoe from among the numberless impedimenta which obstructed navigation.
At the August Falls.
Another most beautiful island, 520 m. long—Jessica Island—was passed just before getting to really formidable rapids, down which we had the greatest difficulty in letting the canoe, even by the judicious use of ropes. The navigable channel of the river—if navigable it could be called—swerved from north-west to due north. In a basin of immense size were a number of islands from 300 to 200 m. in length, and enormous boulders with cataracts of great height between. The roar made by the water falling over was so great that it resembled thunder. The difference of height between the top and the bottom of the rapid was not less than 10 ft. The water in the channel we followed went over a great slope of lava above which numerous boulders had accumulated.
