both sexes, controls this planet. "Transportation is Civilization," our motto runs. Theoretically, we do what we please so long as we do not interfere with the traffic and all it implies. Practically, the A. B. C. confirms or annuls all international arrangements and, to judge from its last report, finds our tolerant, humorous, lazy little planet only too ready to shift the whole burden of private administration on its shoulders.

I discuss this with Tim, sipping maté on the c. p. while George fans her along over the white blur of the Banks in beautiful upward curves of fifty miles each. The dip-dial translates them on the tape in flowing freehand.

Tim gathers up a skein of it and surveys the last few feet, which record "162's" path through the volt-flurry.

"I haven't had a fever-chart like this to show up in five years," he says ruefully.

A postal packet's dip-dial records every yard of every run. The tapes then go to the A. B. C., which collates and makes composite photographs of them for the instruction of captains. Tim studies his irrevocable past, shaking his head.

"Hello! Here's a fifteen-hundred-foot drop at eighty-five degrees! We must have been standing on our heads then, George."

"You don't say so," George answers. "I fancied I noticed it at the time."

George may not have Captain Purnall's catlike swiftness, but he is all an artist to the tips of the broad fingers that play on the shunt-stops. The delicious flight-curves come away on the tape with never a waver. The Mark Boat's vertical spindle of light lies down to eastward, setting in the face of the following stars. Westward, where no planet should rise, the triple verticals of Trinity Bay (we keep still to the Southern route) make a low-lifting haze. We seem the only thing at rest under all the heavens; floating at ease till the earth's revolution shall turn up our landing-towers.

And minute by minute our silent clock gives us a sixteen-second mile.

"Some fine night," says Tim. "We'll be even with that clock's Master."

"He's coming now," says George, over his shoulder. "I'm chasing the night west."

The stars ahead dim no more than if a film of mist had been drawn under unobserved, but the deep air-boom on our skin changes to a joyful shout.

"The dawn-gust," says Tim. "It'll go on to meet the Sun. Look! Look! There's the dark being crammed back over our bow! Come to the after-colloid. I'll show you something."

The engine-room is hot and stuffy; the clerks in the coach are asleep, and the Slave of the Ray is near to follow them. Tim slides open the aft colloid and reveals the curve of the world—the ocean's deepest purple—edged with fuming and intolerable gold. Then the Sun rises and through the colloid strikes out our lamps. Tim scowls in his face.

"Squirrels in a cage," he mutters. "That's all we are. Squirrels in a cage! He's going twice as fast as us. Just you wait a few years, my shining friend and we'll take steps that will amaze you. We'll Joshua you!"

Yes, that is our dream: to turn all earth into the Vale of Ajalon at our pleasure. So far, we can drag out the dawn to twice its normal length in these latitudes. But some day—even on the Equator—we shall hold the Sun level in his full stride.

Now we look down on a sea thronged with heavy traffic. A big submersible breaks water suddenly. Another and another follow with a swash and a suck and a savage bubbling of relieved pressures. The deep-sea freighters are rising to lung up after the long night, and the leisurely ocean is all patterned with peacock's eyes of foam.

"We'll lung up, too," says Tim, and when we return to the c. p. George shuts off, the colloids are opened, and the fresh air sweeps her out. There is no hurry. The old contracts (they will be revised at the end of the year) allow twelve hours for a run which any packet can put behind her in ten. So we breakfast in the arms of an easterly slant which pushes us along at a languid twenty.

To enjoy life, and tobacco, begin both on a sunny morning half a mile or so above the dappled Atlantic cloud-belts and after a volt-flurry which has cleared and tempered your nerves. While we discussed the thickening traffic with the superiority that comes of having a high level reserved to ourselves, we heard (and I for the first time) the morning hymn on a Hospital boat.

She was cloaked by a skein of ravelled fluff beneath us and we caught the chant before she rose into the sunlight. "Oh, ye Winds of God," sang the unseen voices: "bless ye the Lord! Praise Him and magnify Him forever!"

We slid off our caps and joined in. When our shadow fell across her great open platforms they looked up and stretched out their hands neighbourly while they sang. We could see the doctors and the nurses and the white-button-like faces of the cot-patients. She passed slowly beneath us, heading northward, her hull, wet with the dews of the night, all ablaze in the sunshine. So took she the shadow of a cloud and vanished, her song continuing. Oh, ye holy and humble men of heart, bless ye the Lord! Praise Him and magnify Him forever.

"She's a public lunger or she wouldn't have been singing the Benedicite; and she's a Greenlander or she wouldn't have snow-blinds over her colloids," said George at last. "She'll be bound for Frederikshavn or one of the Glacier sanatoriums for a month. If she was an accident ward she'd be hung up at the eight-thousand-foot level. Yes—consumptives."

"Funny how the new things are the old things. I've read in books," Tim answered, "that savages used to haul their sick and wounded up to the tops of hills because microbes were fewer there. We hoist 'em into sterilized air for a while. Same idea. How much do the doctors say we've added to the average life of a man?"

"Thirty years," says George with a twinkle in his eye. "Are we going to spend 'em all up here, Tim?"

"Flap along, then. Flap along. Who's hindering?" the senior captain laughed, as we went in.

We held a good lift to clear the coastwise and Continental shipping; and we had need of it. Though our route is in no sense a populated one, there is a steady trickle of traffic this way along. We met Hudson Bay furriers out of the Great Preserve, hurrying to make their departure from Bonavista with sable and black fox for the insatiable markets. We over-crossed Keewatin liners, small and cramped; but their captains, who see no land between Trepassy and Blanco, know what gold they bring back from West Africa. Trans-Asiatic Directs, we met, soberly ringing the world round the Fiftieth Meridian at an honest seventy knots; and white-painted Ackroyd & Hunt fruiters out of the south fled beneath us, their ventilated hulls whistling like Chinese kites. Their market is in the North among the northern sanatoria where you can smell their grapefruit and bananas across the cold snows. Argentine beef boats we sighted too, of enormous capacity and unlovely outline. They, too, feed the northern health stations in ice-bound ports where submersibles dare not rise.

Yellow-bellied ore-flats and Ungava petrol-tanks punted down leisurely out of the north like strings of unfrightened wild duck. It does not pay to "fly" minerals and oil a mile farther than is necessary; but the risks of transhipping to submersibles in the ice-pack off Nain or Hebron are so great that these heavy freighters fly down to Halifax direct, and scent the air as they go. They are the biggest tramps aloft except the
