The first man to reach the gallery after Brand was Pyne, who chanced to be nearest to him when the hubbub arose. He found the other man flinging handfuls of the oil as far to windward as the thick fluid would travel.

"Quick!" gasped Brand. "Don't pour it out! It must be scattered."

So the colza fell in little patches of smooth tranquillity into the white void beneath, and, before Stanhope had piloted his boat half the remaining distance, the wave-currents surging about the rock ceased to toss their yellow manes so high, and the high-pitched masses of foam vanished completely.

The seamen stationed in the entrance were astonished by the rapidity of the change. In less than a minute they found they were no longer blinded by the spindrift cast by each upward rush right into the interior of the lighthouse. The two nearest to the door looked out in wonderment. What devilment was the reef hatching now, that its claws should relax their clutch on the pillar and its icy spray be withheld?

Each wave, as it struck to westward of the column, divided itself into two roaring streams which met exactly where the iron rungs ran down the wall. There was a mighty clash of the opposing forces and a further upward rearing of shattered torrents before the reunited mass fell away to give place to its successor.

Full twenty feet of the granite layers were thus submerged and exposed whenever a big comber traveled sheer over the reef.

But these straight-forward attacks were spasmodic. Often the eddies created by the rocks came tumbling pellmell from the north. Sometimes they would combine with the incoming tide, and then the water seemed to cling tenaciously to the side of the lighthouse until it rose to a great height, swamping the entrance, and dropping back with a tremendous crash. There were times when the northerly ally disdained to merge with its rival. Then it leaped into the hollow created by the receding wave, and all about the lighthouse warred a level whirlpool.

Stanhope's plan was to rush the boat in when one of these comparatively less dangerous opportunities offered. He would spring for the ladder, run up if possible, but, if caught by a vaulting breaker, lock himself with hands and feet on the iron rungs and endeavor to withstand the stifling embrace of the oncoming sea. He was sure he could hold out against that furious onslaught, once at least. He was an expert swimmer and diver, and he believed that by clinging limpet-like to the face of the rock, he had the requisite strength of lungs and sinews to resist one if not more of those watery avalanches.

The rope around his waist was held from the tug. The instant he made his leap, the men with him were to back water, the crew at the drag to haul for all they were worth, and consequently pull the boat clear of the next wave 'ere it broke. That is why he selected a handy craft in place of the life-boat offered to him as soon as his resolve was whispered ashore. It was on rapidity, quick judgment, the utilization of seconds, that he depended. The unwieldly bulk of the life-boat not only detracted from these all-important considerations, but made it more than probable that she would be capsized or touch the reef.

For the same reason he timed his approach on the rising tide. He could venture nearer to the lighthouse itself, and the boat could be rowed and dragged more speedily into safety. With him, too, were men who knew every inch of the Gulf Rock. He knew he could trust them to the end.
