In a twinkling the first patch was ready. Dave himself helped with weighting what was intended for the lower edge of the patch, and with reeving in ropes at the sides and top.

"Over with it!"

Lowered down into place, the patch was fitted to the hole. It still had to be made fast.

Both port and starboard gangways had been lowered, and launches from the destroyer were alongside, receiving badly wounded men who had been taken over the side on stretchers. The "Grigsby's" cutters were also alongside, picking up such of the wounded men as could jump in life belts. The "Gloucester's" own boats swung out after being loaded. The mine-sweepers had come up and had lowered their boats and sent them to the rescue. Several hundred men and women were reasonably sure of being saved, but unless Darrin succeeded in what he was undertaking, from twelve to fifteen hundred other human beings were surely doomed.

Badly as boats were needed, Dave had to commandeer two of the smallest. Himself going in one of these, he superintended the making fast of the canvas patches below from the water. Seamen over the hull's side in slings, acting under the second mate, did valiant service at the same time.

With a single outside canvas patch over the forward hole, Darrin moved back to the second breach. Here, too, a patch was quickly put in place.

By this time the "Grigsby" and the mine-sweepers had received nearly as many rescued passengers as they could hold. The small boats were returning for more.

Up to Dave rushed Captain Senby of the "Gloucester."

"Captain," he called, addressing Dave Darrin by that courtesy title, "these Red Cross women ought to be saved while there's time, but they refuse to go over the side until their patients are safe."

"Did you expect they would desert their patients?" Darrin asked quietly, his gaze still on the work that he was directing.
