"S.O.S. call, sir; H.Q.C.P. reports being in collision with a derelict—lat. 22°5'10" N., long. 15°50'20" W."

The thought flashed through the "old man's" mind that the message might be a decoy; yet the claims of humanity urged him to alter course and steam at full speed to the rescue.

Meanwhile Aubyn had referred to the "British Code List," in which he found that the signal letters H.Q.C.P. denoted the SS. "Corona," of West Hartlepool, of 2576 registered tonnage and of 720 horse-power. The "Corona," he knew, was a tramp engaged in running between the Tyne Ports and the Gold Coast.

Captain Ramshaw gave no inkling of the doubt that existed in his mind. He immediately ordered the "Saraband" to be steered towards the position indicated, although he would not allow the wireless to be made use of in order to acquaint the distressed vessel that help was forthcoming. This was one of the steps he took to guard against the base misuse of the hitherto inviolate S.O.S. call. In addition, as previously, the guns' crews stood by their two powerful weapons.

Hour after hour passed as the "Saraband" sped on her errand of mercy. Fitfully the S.O.S. was received as if the ill-fated crew of the "Corona," despairing at not having news that their message had been picked up, were still calling for aid from passing vessels.

Down below McBride's staff was working heroically. The firemen, stripped to the waist, were shovelling coal with rapid yet dexterous haste. Stoking is an art: it requires more than merely piling fuel into the furnaces; but there was no lack of capability on the part of the "Saraband's" stokehold staff. Quickly the old boat worked up to her maximum speed.

"Light on the port bow, sir," sung out the mastheadman. "Red flame throwing out red stars."

"That's the 'Corona' then," declared the "old man." "Starboard your helm, quartermaster: keep her at that. Mr. Lymore, see that the cutter is cleared away."

"Ay, ay, sir," replied the chief officer.

The signal of distress flare was calculated to be seen from twelve to fourteen miles off In three-quarters of an hour the "Saraband" would be on the spot, by which time daylight would have dawned.
