It was mid-December, and flurries of snow were being driven before a stinging north-westerly wind. The sea was moderate, but the heavy Atlantic swell caused the lonely patrol ship to sink sluggishly into the watery hollows, with only her aerials showing above the surrounding slopes of grey-green sea, and a minute or so later to be poised giddily on the bosoms of acre-wide rollers with nothing but the white mists obscuring the broad horizon. It was a wild wintry scene, pregnant with cold and hardship. The officer who had just come up from the warmth of the wardroom to relieve his "opposite number" on the bridge pulled the thick wool muffler closer round his neck and dug mittened hands deep into the pockets of his duffel coat. In the Marconi cabin, situated on the deck of the _sloop_, a young operator was sitting with the receiving instrument fixed to his head and the clean and bright apparatus all around. He was city born and bred, and felt keenly the monotony of life at sea, although to him came the many interesting wireless signals from the vast network of patrols which covered the Western Ocean--linking the sea-divided units into a more or less homogeneous fleet. Presently a message began to spell itself in Morse. Taking a pencil, the operator scribbled various hieroglyphics on the naval signal paper lying on the desk in front of him; then after a pause of a few seconds he pulled forward a tiny lever and began a rhythmic tap on an ebonite key. It was the "S.O.S." call and the reply that had flashed through the ether. A minute or so later the written signal, giving the appeal for help and the position and name of the torpedoed liner, was handed to the commander. A glance at the chart told that young but experienced officer that he could not hope to bring his ship to the scene of the disaster before dusk closed down, and a message was sparked across the eighty miles of intervening sea asking how long the crippled ship could be kept afloat. To this, however, there came no reply, and the engines of the sloop were put to full speed ahead. A heavy spray now commenced to sweep across the deck in drenching showers, and the snow haze thickened. The pitching of the ship increased as she raced over the ocean swell, driving her sharp bows deep into the masses of sea. The limbs of the watch grew stiff and numb, and a fine coating of wet salt stung their faces. Eyes ached from gazing into the bitter wind, and for over four hours the race against approaching night continued. If darkness closed down before that eighty miles of sea was covered all on board realised that the chances of finding any survivors would be greatly diminished. Even the strongest vitality could not long resist exposure to the intense cold, and there might be women and children in the sea ahead.
