"Consolidation, not Coöperation." There's a real phrase. And thanks to the great man who said it and insisted upon it, we defeated the common enemy.

MACHINE AGAINST MACHINE

The year stood at the threshold of the spring; a promise of warmth lay in the climbing sun; on land one might have heard the first songs of the birds. At sea, the mists of winter were lifting from the waters, and the sun, for many months shrunk and silver pale, shone hard and golden bright. A fresh, clear wind was blowing from the west, driving ahead of it a multitude of low foam-streaked waves. There was not a sign of life to be seen anywhere on the vast disk of the sea, not a trail, not a smudge of smoke on the horizon's circle, not even a solitary gull or diver. The destroyer, dwarfed by her world, ran up and down the square she had been chosen to guard. She had the air of performing a casual evolution. There was never anything to be found in this particular square. It lay beyond the great highways; even the sight of a coaster was there something of a rarity. Periscopes were never reported from that area, never had been reported, and probably never would be. Caressed by the sun, enveloped in the serenity of the day as in a mantle, the destroyer went back and forth on her patrol.

The emergence of the periscope a quarter of a mile ahead off the starboard bow had in it something so unattended that the incident had a character of abnormality ... much as if a familiar hill should suddenly turn into a volcano. It is greatly to the honour of the ship's discipline, that those aboard were not staled by months of unfruitful vigil, and acted as swiftly as if the destruction of a submarine were matter of daily practice. There it lay, going steadily along about two hundred yards away, ... a simple, most unromantic black rod rising two feet or so above the waves. A white furrow like a kind of comet's tail, streamed behind it, forever widening at the end. Later on, they asked themselves what the submarine could possibly have been doing. Seeking a quiet place to come up to breathe, to effect repairs, to send out a hurried wireless message?

It might have been a rendezvous between the two vessels. One felt that the gods had brought to pass there no careless drama, but a tragedy long meditated and skillfully prepared. The morning sun watched, a casual spectator, the duel between the two engines of violence.

There had been a command, a call of the summoning bell, a release of power carefully stored for just such an event, and the destroyer leaped ahead like a runner from the starting line. The periscope, meanwhile, continued to plough its way straight ahead almost into the teeth of the wind and the flattened, marbly waves. Presently, either because the destroyer had been seen or heard on the submarine telephone, the submarine began to submerge, sucking in a kind of a foaming hollow as she sank. Aboard the destroyer, they wondered if the keel would clear her, and waited for the shock, the rasping grind. But nothing happened. The first depth bomb fell into the heart of the submarine's swirl even as a well placed stone falls in the heart of a pool. Trembling to the roar of her fans, the destroyer fled across the spot, and turned. The wake of her passing had almost obliterated the platter-shaped swirl the submarine had left behind; one had a vision of the great steel cylinder tumbling, bubbling down through green water to dark, harmless as a spool of thread on the surface, but presently to be changed by the wisdom and cunning of men into monstrous and chaotic strength. One, two, three, four, five ... a thundering pound.... The submarine rose behind them, her bow on the crest of the geyser, an immense, tapering rusty mass, wet and shining in the placid glance of the day. From a kind of hole some distance up the side, a stream of oil ran much like blood from a small deep wound.... A gun spoke, and spoke again, a careening whizz, ... ugly hollow crashes of tearing steel ... the sub heeled far over on her starboard side ... those nearest heard, or thought they heard, screaming ... the bow sank, tilting up the great planes and propellers. A monstrous bubble or two broke on the tormented surface just before she disappeared ... and with her going, the calm of the spring morning, which had been frightened away like a singing bird, returned once more to the tragic and mysterious sea.

THE LEGEND OF KELLEY

Kelley, not Von Biberstein or Hans Bratwurst, is his name, Kelley spelled with an "e." The first destroyer officer whom you question will very possibly have never heard of him, the second will have heard the legend, the third will tell you of a radio officer, a friend of his, who received one of Kelley's messages. So day by day the legend grows apace. Kelley is the captain of a German submarine.
