We started at one knot full steam ahead, and the Ariel creaked as she crept out into the lake. The rain and mist from the direction of the Cordillera had blotted out all sight of them, and were beating down on us steadily. The rain, however, was in reality favourable to our attempt, as it served to smooth the water. The short waves leaped up under every puff of wind, but the launch ran along past the mouth of the river, attaining to a quite respectable speed as she proceeded.

A nasty little squall struck us for a moment as we were broadside on, but it passed, and then, with her nose pointed toward the Cordillera, the launch described a large circle, and we allowed her to be slowly sucked stern first into the power of the fierce current of the Leona. At length it got hold of her, and, adopting a cautious policy, we gave her full speed ahead against the current, which had the effect of letting us drop down stream at about two knots an hour.

Just before we entered the rip of the current I saw a rock a couple of feet off on the starboard side; it was only a few inches under the surface, but luckily we slipped by without harm. We got on pretty well in this fashion through the whole afternoon; it was raining pitilessly all the time. Bernardo, who was acting as engineer, at one period ran the engine at a pressure of 30 lb. above safety, until it was explained to him that, if he continued doing so, it was probable he would see Sweden no more.

Towards evening the weather cleared into the most lovely blue afternoon, and we camped for the night at the spot we had before chosen, having some fifteen miles of our voyage behind us. We pitched the tent and I crawled into it and lit a pipe with a vivid question in my mind as to when I should do so again. You could hear the river growling and gulping at its banks. I felt I had never before realised how warm and comfortable that little tent was. The next day would decide the success of our expedition or otherwise, and all the worst of the river lay before us. I cannot deny that I disliked the thought of the morrow. Familiarity with the River Leona is not apt to breed contempt. Its channel was made up of sharp bends and curves, and if the launch by any untoward accident were to swing round, we should be forced to steam faster than the current, and at that speed she would certainly split herself from stem to stern if she touched. Besides, she answered her helm badly, and the river in places was very narrow.

But, for all this, our success so far had had its effect, and we resumed our voyage next morning in high spirits. We began by negotiating a nasty passage among the rocks with neatness. The river then became very erratic and winding in its course, and almost at once the current caught us, and it seemed as it some gigantic hand were pushing the panting launch slowly round. Steering was no easy matter, she was canted badly, and we discarded some of our heavy clothes, raw as the air was, preferring the cold to the chance of sinking should anything happen.

In places the rip was very strong and the curving pearl-grey water gave but a poor opportunity of observing any rocks that might lie in our course. We were by this time able to manage the launch better and were beginning to understand more or less her special peculiarities.

Then the dreaded event came to pass. We were sagging down with about 70 lb. of steam in the boiler, when a heavy squall, which had long been brooding darkly over the Cordillera, rushed suddenly upon us. The launch, under the fury of the wind, turned almost broadside on to the current, and it became necessary to give her her head.

Bernardo, who had had his orders as to what to do in case such an eventuality occurred, flung open the furnace-door and piled on wood to get a heavy head of steam on. The Ariel's powers had much improved with use, and she was able to race along ahead of the current, a fact which gave her steerage-way.

"She's steering a bit better," shouted Cattle; "if Bernardo can keep up the pressure it may be all right." Bernardo, evidently feeling that the moment needed commemoration, blew the whistle and grinned.

Now that she was turned prow-first, any attempt to get the boat back to her old position would have been more risky than to go forward, for the river at this part was much narrower and the current proportionately more rapid. Bernardo poked his head up from the engine-hatch and laughed, "She go fine this way," he remarked. At the moment a rock glimmered up close to the bows, but we slipped over it with a few inches to spare.
