board had I not fortunately grasped his ankle as he was already partially over.
Unguided, our vessel careened wildly in its mad flight, rising ever nearer the rocks above. It took but an instant, however, for me to regain the levers, and with the roof barely fifty feet above I turned her nose once more into the horizontal plane and headed her again for the black mouth of the shaft.
The collision had retarded our progress and now a hundred swift scouts were close upon us. Xodar had told me that ascending the shaft by virtue of our repulsive rays alone would give our enemies their best chance to overtake us, since our propellers would be idle and in rising we would be outclassed by many of our pursuers. The swifter craft are seldom equipped with large buoyancy tanks, since the added bulk of them tends to reduce a vessel's speed.
As many boats were now quite close to us it was inevitable that we would be quickly overhauled in the shaft, and captured or killed in short order.
To me there always seems a way to gain the opposite side of an obstacle. If one cannot pass over it, or below it, or around it, why then there is but a single alternative left, and that is to pass through it. I could not get around the fact that many of these other boats could rise faster than ours by the fact of their greater buoyancy, but I was none the less determined to reach the outer world far in
