Yet the men at the oars did not falter nor turn their heads. They pulled evenly and well, with the short, deep-sunken stroke of the fisherman, and Stanhope, now that they were almost in the vortex where the waves lost their regularity, produced a paddle wherewith to twist the boat's head to meet each turn and swirl.
Stealthily the powerful tug-boat crept in the wake of the smaller craft, until it became clear to the girls' strained vision that watchful helpers, lashed in the vessel's bows, were manipulating another rope as a drag, thus helping the sailors' efforts to prevent his frail argosy from being swamped by a breaking sea.
Then a miracle did happen, a miracle of science. When the boat was yet two hundred yards away, Brand, looking out from the gallery in stony despair, suddenly behaved as one possessed of a fiend.
"Follow me!" he roared. "Come, every man!"
He rushed into the lantern. As if he wanted wings rather than limbs, he swung himself by his hands to the floor of the service-room.
Galvanized into activity, those who were with him on the ledge raced after him. They knew not what had happened. Their leader had spoken, and they obeyed.
Down, down, they pelted, taking the steep stairs with break-neck speed, until they reached the oil-room, with its thousands of gallons stored in great tanks.
Big empty tins stood there, awaiting the next visit of the tender, and Brand wrenched the cover off the nearest cistern. He scooped up a tinful of the oil.
"Bring all you can carry," he shouted, and was off again with an energy that was wonderful in a man who had endured the privations and hardships of so many hours.
They understood. Why had none of them thought of it earlier? In its cold granite depths the lighthouse carried that which had the power to subdue the roaring fury of the reef.
