They were indeed; I could see them in all the towers underneath me. I was flying north-east; and at the moment, with a following wind, I was doing something over three-fifty.
"But they'll shut off your power," Grille warned. "You'll come down soon enough then."
Which was also true enough. The evening local-express for Boston and beyond was overhauling me. And when the green beam of a traffic tower came up and picked me out, I decided I had better obey. Dutifully I descended until the beam, satisfied, swung away from me.
At 8,000 feet, I went on. There was too much traffic for decent speed and the directors in every pilot bag and tower I passed seemed watching me closely. At the latitude of Boston, I swung out to sea, off the main arteries of travel. The early night mail for Eurasia,[4] with Great London its first stop, went by me far overhead. I could make out its green and purple lights, and the spreading silver beam that preceded it.
Alone in my pit, with the dull whir of my propellers alone breaking the silence of the night, I pondered the startling events of the past few hours. Above me the stars and planets gleamed in the deep purple of an almost cloudless sky. Venus had long since dropped below the horizon. But Mars was up there—approaching the zenith. I wondered what the Martian helio might be saying. I could have asked Greys back at the office. But Greys, I knew, would be too busy to bother with me.
What could Dr. Brende want of me? I was glad he had sent for me—there was nowhere I would rather have gone this particular evening. And it would give me a chance to see Elza again.
I could tell by the light-numerals below, that I was now over Maine. I did not need to consult my charts; I had been up this way many times, for, the Brendes—the doctor, his daughter Elza, and her twin brother Georg—I counted my best friends.
I was over the sea, with the coast of Maine to my left. The traffic, since I left the line of Boston, had been far less. The patrols flashed by me at intervals, but they did not molest me.
I descended presently, and located the small two-mile island which Dr. Brende owned and upon which he lived.
It was 10:20 when I came down to find them waiting for me on the runway.
