"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 un.o.bserved, but the deep airboom 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 bows! 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 ready 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 Yale of Ajalon at our pleasure. So far, we can drag out the dawn to twice its normal length in these lat.i.tudes. 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 follows 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 peac.o.c.k'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 G.o.d," sang the unseen voices: "bless ye the Lord! Praise Him and magnify Him for ever!"

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-b.u.t.ton-like faces of the cot-patients. She pa.s.sed 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 for ever."

"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 thing 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 in sterilized air for a while. Same idea. How much do the doctors say we've added to the average life of man?"

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

"Flap ahead, then. Flap ahead. 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 overcossed Keewatin liners, small and cramped; but their captains, who see no land between Trepa.s.sy and Lanco, know what gold they bring back from West Erica. 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 grape-fruit 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 icebound 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 Athabasca grain-tubs. But these last, now that the wheat is moved, are busy, over the world's shoulder, timber-lifting in Siberia.

We held to the St. Lawrence (it is astonishing how the old water-ways still pull us children of the air), and followed his broad line of black between its drifting iceblocks, all down the Park that the wisdom of our fathers--but every one knows the Quebec run.

We dropped to the Heights Receiving Towers twenty minutes ahead of time, and there hung at ease till the Yokohama Intermediate Packet could pull out and give us our proper slip. It was curious to watch the action of the holding-down clips all along the frosty river front as the boats cleared or came to rest. A big Hamburger was leaving Pont Levis and her crew, unshipping the platform railings, began to sing "Elsinore"--the oldest of our chanteys. You know it of course:

Mother Rugen's tea-house on the Baltic Forty couple waltzing on the floor!

And you can watch my Ray, For I must go away And dance with Ella Sweyn at Elsinore!

Then, while they sweated home the covering-plates:

Nor-Nor-Nor-Nor West from Sourabaya to the Baltic-- Ninety knot an hour to the Skaw!

Mother Rugen's tea-house on the Baltic And a dance with Ella Sweyn at Elsinore!

The clips parted with a gesture of indignant dismissal, as though Quebec, glittering under her snows, were casting out these light and unworthy lovers. Our signal came from the Heights. Tim turned and floated up, but surely then it was with pa.s.sionate appeal that the great tower arms flung open--or did I think so because on the upper staging a little hooded figure also opened her arms wide toward her father?

In ten seconds the coach with its clerks clashed down to the receiving-caisson; the hostlers displaced the engineers at the idle turbines, and Tim, prouder of this than all, introduced me to the maiden of the photograph on the shelf. "And by the way," said he to her, stepping forth in sunshine under the hat of civil life, "I saw young Williams in the Mark Boat. I've asked him to tea on Friday."
