"Look here!" The sunset light was almost gone, but one could still see a snow-white cloud sailing high overhead.

Guy pointed. "Look" We went outside. A tiny dot was far up there, dropping out of the cloud. We knew it was not Tama. It came down like a plummet, resolved itself presently into a midget monoplane descending almost with a nose dive.

. ' "Jimmy's dragon," I said. "He must have been at fifty or sixty thousand feetdropping through those cloudsmaking sure nobody is trailing him here." Jimmy landed on the snow nearby. Climbing from his little pit, he was a shapeless bundle in his electrically warmed flying suit. In our living room he revealed himselfa short, stocky, redheaded little daredevil, with an unfailing grin.

"Hello, folks! A damned B.P.A. plane was after me when I left the city. Hope they had a good trip. I say, how about a cup of coffee?"

"Oh, 1m sorry," Rowena apologized. "Of course you'll want something. I'll tell Eliza." Eliza was our one servent, a middle-aged woman. She and Rowena returned presently with a hot breakfast for Jimmy.

"What brought you, Jimmy?" I demanded.

"Oh, )ust to see you. Don't I have to see my buried friends every so often?"-His grin faded. "I've got news, a message for you from Grenfell: We're definitely goingthe Cube is starting for Mercurythe tentative date is March thirtieth... . I say, Rowena, you do serve the most marvelous coffee." He took it as lightly as that I In two weeks we were leaving for Mercury. My heart pounded at the thought of it. We had been waiting here only for Grenfell's decision.

Jimmy went on: "Inferior Conjunction is the first week in.

Aprilthe shortest distance. I've been down to see the Cube.

They've got perfect equipment this time. Everything's about ready. Grenfell wants you in Trenton in about a week, say March twenty-second." The Flying Cube had been built and now was housed in the midst of the huge buildings of the Bolton Metal Industries near Trenton, New Jersey.
