The problems were, therefore, first, to remove the body which lay in the tunnel entrance to a place of safety, where it could be repaired, and its owner could resume it; and second, to rescue her companion either by force or subtlety, bringing their faculty of thinking in unison, and of combined will-power, to operate against opponents who were not expecting attack, and who relied upon their savage strength and weapons to maintain their own security, and to hold the prey that they had captured; and third, to do these things, if either were possible, without the knowledge of the Dwellers, whose means of information were only vaguely guessed, but who were known to come out on the surface in the daytime. CHAPTER XII THE MARCH We were now clear of the covered way, under a sky of brilliant starshine, holding a course through the darkness that never wavered or slackened, even when the gorge was crossed by the invisible bridge. Here it occurred to me to ask how, if the country relied upon its girdle of strange growths for its immunity from the outside world, it could afford to risk invasion up so wide an unprotected channel as the gorge supplied, but I could learn nothing beyond the suggestion that its enemies would probably be too stupid to discover the gap, (if it really were unprotected), which seemed a strange supposition when applied to a power so dreaded, and the information that this gorge was remembered as the scene of a great battle before the protective girdle had been planted, in which the Dwellers had been destroyed in hundreds, but in which one of their enemies had also perished, and the remains of its body had blocked the channel for many years afterwards. I had thought of the Dwellers hitherto as dominating by their strength and size, as well as by their evident physical knowledge and engineering skill, in both of which my present companions appeared to take little interest, but I now had a vision as of a world in which a race of ants of superior intelligence might revolt successfully against mankind, and of a warfare in which they had been trodden down, as a man might stamp on an ant’s nest. But the truth, as I learnt later, was somewhat different. My companion now pressed for some account of myself, and I answered many questions, finding her more ready to believe that I was the product of an earlier civilisation than I should have anticipated, but that this information made it appear the more necessary that the Dwellers should be informed of my existence, and the less probable that they would regard it with complacency.
