We cast away before the sound of the first gun had died, and another second saw us rising swiftly from the surface of the sea. I lay at full length along the deck with the levers and buttons of control before me. Xodar and the boy were stretched directly behind me, prone also that we might offer as little resistance to the air as possible.

"Rise high," whispered Xodar. "They dare not fire their heavy guns toward the dome--the fragments of the shells would drop back among their own craft. If we are high enough our keel plates will protect us from rifle fire."

I did as he bade. Below us we could see the men leaping into the water by hundreds, and striking out for the small cruisers and one-man fliers that lay moored about the big ships. The larger craft were getting under way, following us rapidly, but not rising from the water.

"A little to your right," cried Xodar, for there are no points of compass upon Omean where every direction is due north.

The pandemonium that had broken out below us was deafening.
