He would carry on the war to the end. As it stood on the beach below the cottage, the Omnimobile was a strange-looking machine. Gleaming like silver in the bright sunshine of those last days, it looked like a vast metal monster. It was bulky, almost clumsy looking; but it had somehow the air of an irresistible strength that could force a way through forests and surmount mountain peaks. In its resistless power, it suggested the old saurian lords of the jungle. With its low, thick body, and the massive strength of its construction, there seemed little doubt that it might go almost anywhere it chose, and be able to take care of itself upon arrival. The last day came. For two weeks we had been ready to move aboard whenever the alien force brought the frozen night again to earth. I had been living in it, while Sam spent most of his time in the laboratory. I whiled the time away by wandering on the beach, bathing in the surf, or dreaming idly.

I had a book in my hand, but it was closed, and I was gazing out at the sea. Sam was still at the house, although it was past our usual supper time. Suddenly my attention was attracted by a faint hail. I glanced toward the cottage and
