I had ordered that none of the rays be flashed at this time, and it must have been difficult for the men in the boats below to see us in the dusk, shrouded as we were in black. They sent up a rocket once; it mounted above us in a slow flaming arc, hung poised an instant, and then descended, plunging into the sea a mile or so away. We heard distinctly the hiss of its contact with the water, and saw, like a quickly dissipating mist, the cloud of steam that arose.

We were not armed with these rockets, for to discharge them from the platforms would have been impractical. But we did not fear them being used against us. Even if true aim had been possible, we could easily avoid their slow flight.

The protecting canopy below the sides of our platform made it difficult to see what was going on below us. Miela and I lay prone, with our heads projecting over its forward end. In this position we had an unobstructed, though somewhat limited, view. The girls carrying us could see nothing. They were guided by watching the other girls flying near them, and by Miela's constant directions.

For some ten or fifteen minutes we circled about over the leading boat. The Twilight shore was now almost over the horizon. The boats showed as little black patches on the gray‑black of the sea, but the lights flashing up from them were plainly visible.

The boat that led the line was quite perceptibly drawing away from the others. Already it was a thousand feet or more ahead of the nearest one following. We waited through another period. This leading boat was now beyond range of the others, and, being isolated, I decided to attack it.

"Miela," I said, "tell them all to maintain this level. You and I will go down at that first boat. Have them all remain up here. Tell Mercer if anything goes wrong with us to act as he thinks best."

We waited while these commands were circulated about. Mercer's platform swept close over us, and he shouted: "We won't stay up here."

I persuaded him finally, and then we directed our girls to circle slowly downward with our platform. I ordered a slow descent, for I was in no mind to rush blindly into range of their ray.

We drooped down in a spiral, until at about fifteen hundred feet I ordered the girls to descend no farther. So far as I could make out now, this boat was protected from above by a broad overhanging canopy. Its sides evidently were open, or nearly so, for we could see now the smaller rays flashing out horizontally.

The large projector was mounted in the bow beyond the canopy. Its beam obviously could be directed into the air, for it was now swinging up toward us. But in the horizontal position its range was limited to an arc in front of the boat. I saw then that our play was to attack from a low level, since only in that way could we expect to reach a vulnerable spot in the boat's armor. And I believed that if we could keep behind it they could not reach us with their larger projector.
