"Two are running," she said. "They are together. Hasten."

We jumped out of the boat. Miela flew up, and we followed her guidance through the dense woods. We could make much better speed, I knew, than the Mercutians. "We'll get them all, Ollie," I shouted at Mercer. "They're not far ahead. See up there—Miela's evidently over them now."

We came up to them after a few hundred yards. It was the old man, and one of those whom I had first encountered. They did not wait for us to attack them, but stopped stock still, flinging their arms wide in token of surrender.

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.
