Miela came down among us, and we went back to where we had lain hidden in the palmettos. There we had left a number of short lengths of rope. While we were tying the arms of these two prisoners behind them and fettering their ankles so they could not run Anina joined us. "Two--in water," she cried; and then added something to Miela. "Two were in the water. Now they are in the woods, running. Anina will show you." Miela stood guard in the boat over our first two prisoners, while Mercer and I rounded up the others. It was half an hour or more before we had them all trussed up, but none of the ten escaped. We were a long time reviving two of those we had injured, but finally we had them all lying or sitting in the boat. Mercer's head had stopped bleeding. He washed it, and I found his injury no more than an ugly scalp wound. "I fell and cut it on something," he explained lugubriously. "Couldn't see for the blood in my eyes. But we got 'em, didn't we?" Under Miela's direction Mercer and I shoved the boat out into the stream. I need not go into details regarding the propelling mechanism of this craft. Miela explained it hastily to me as we got under way. It used a form of the light-ray from a sort of strange battery. The intense heat of the ray generated a great pressure of superheated steam in a thick metal cylinder underneath the keel. This steam escaped through a nozzle under water at the stern of the boat, and its thrust against the water propelled the boat forward. The boat was constructed to draw very little water, and when going fast its bow planed upward until only the stern of the hull touched the surface. It was steered by a rudder not much different from some of those types we are familiar with on earth. When we got out into open water I found the boat was capable of great speed. This I attributed not so much to the efficacy of its propelling force as to the lightness of the boat itself. It was built of some metal that I may perhaps compare with aluminium, only this was far stronger and lighter. The boat was, in fact, a mere shell, extraordinarily buoyant. Miela sat in the stern, steering and operating the mechanism. I sat with her. Mercer was farther forward, beside Anina, talking to her earnestly. Our prisoners lay huddled in various attitudes--frightened, all of them, and obviously in no condition to give us further trouble. They were, I saw now, not ruffians by any means, but rather men of superior intelligence, selected by Tao evidently as those best fitted for spreading his propaganda among the people of the Great City. We made slow progress down the bayou. Some of its turns were so sharp and so overhung with trees, and obstructed by fallen logs, we could hardly get through. During the latter part of the trip the bayou broadened rapidly, dividing into many channels like a delta.
