They would, however, continue to watch for a while, and would know, from the direction which would shortly be taken, that the expedition was turning into the mountains. Their masters would know that no danger could threaten from that direction for a space of one or two days, as the distance to be covered was not less than five hundred miles, and part of it was over very difficult surfaces, whereas we were only about one hundred and thirty miles from their stronghold, if the direct course were taken, and the trenches which I have mentioned, which were well drained on the higher slopes, provided a road along which the Amphibians could have proceeded with great rapidity. The distances were, of course, conveyed to me visually and not by terms of measurement. The way through the mountains was, for the Amphibians, sufficiently hazardous, and would be, for me, impossible; and the Five had decided that it would be best for me to proceed with my one companion by the easier way, where it might be anticipated that my presence would not be suspected, and myself to attempt the rescue, by peaceful stratagem if possible, or by force if it should be necessary to do so. My companion would supply the nervous energy necessary to enable me to cover the intervening distance in the forty-eight hours which yet remained before sunset, while, if any physical violence were necessary to effect my purpose, I should be acting according to the laws of my own nature, and against creatures more or less on my own level of conduct. The enclosure which it would be necessary to enter I had already seen in the vision. It was the custom to place all the hunting weapons of the tribe during the night in a central building, which was not guarded, as no attack was ever anticipated from outside, particularly during the long night, when all the creatures on the earth’s surface rested. The building in which were the killing-pens was guarded day and night by one of the giant archers, lest its victims should attempt escape, and for other reasons which I could not follow. The main force of the expedition would arrive, if all went well, on the top of the great cliff which overlooked the enclosure, at the commencement of the second night. Had I found it impossible to attempt a rescue, or had I failed, they would then proceed by other methods. Should I succeed, I was to place myself under the orders of the one I rescued, who, being one of the Leaders, would naturally assume control of myself and my companion. I was given a few minutes to consider this plan, and to make any inquiries which might occur to me, while our course continued in the same direction.
