"I can't get your message to the —— (another battleship), sir. I can't raise her. Been trying for ten minutes."

The officer who has been below at the detector comes up and hears the plight of the wireless man. He smiles.

"In exactly five minutes," he says, "you signal again." The radio man goes to his room and the officer descends to the detector. In precisely five minutes he hears the signal which had bothered the man on detector watch. He hurries to the bridge with the solution of the incident. The wireless had become disconnected and its signals had come in contact with the detector. So there was no submarine. Everything serene. The battleship settles down to her night routine.

The dark wears into dawn, and the early morning, with the dusk, is the favorite hunting-time of the submarine, for the reason that then a periscope, while seeing clearly, is not itself easily to be discerned. The lookouts, straining their eyes out over the steely surge, pick up what appears to be a spar. But no. The water is rushing on either side of it like a mill race. A periscope.

There is a hurry of feet on the bridge. The navigating officer seizes the engine-room telegraph and signals full speed ahead. While the ship groans and lists under the sudden turn at high speed, the ammunition-hoists drone as they bring powder and shell up to gun and turret. From the range-finding and plotting-stations come orders to the sight-setters, and in an instant there is a stupendous roar as every gun on the port side sends forth its steel messenger.

Again and again comes the broadside, while the ocean for acres about the periscope boils with the steel rain. It is much too hot for the submarine which sinks so that the periscope is invisible. From the plotting-stations come orders for a change of range, and on the sea a mile or so away rise huge geysers which pause for a moment, glistening in the light of the new sun, and then fall in spray to the waves, whence they were lifted by the hurtling projectiles. The shells do not ricochet. "Where they hit they dig," to quote a navy man. This is one of the inventions of the war, the non-ricochet shell. One may easily imagine how greatly superior are the shells that dig to those that strike the water and then glance. Then comes the cry:

"Torpedo!"

All see it, a white streak upon the water, circling from the outer rim of shell-fire on a wide arc, so as to allow for the speed of the battleship. With a hiss the venomous projectile dashes past the bow, perhaps thirty yards away. Had not the battleship swung about on a new course as soon as the vigilant lookout descried the advancing torpedo, it would have been a fair hit amidships. As it was, the explosive went harmlessly on its way through the open sea. A short cheer from the crew marks the miss, and the firing increases in intensity. The battleship so turns that her bow is in the direction of the submarine, presenting, thus, a mark which may be hit only through a lucky shot, since the submarine is a mile away. Accurate shooting even at a mile is expected of torpedo-men when the mark is a broadside, but hitting a "bow-on" object is a different matter.

Two more torpedoes zip past, and then over the seas comes bounding a destroyer, smoke bellying from her funnels. She is over the probable hiding-place of the submarine, and a great explosion and a high column of water tell those on the battleship that she has released a depth-bomb. Suddenly a signal flutters to the stay of the destroyer. The crew of the battleship cheer. There is no more to fear from that submarine, for oil is slowly spreading itself over the surface of the ocean—oil and pieces of wreckage.

The dawn establishes itself fully. The battleship resumes her course toward the appointed rendezvous.
