Villiers swept the edge of the cliff with the powerful light. Away to the right the land terminated in a low promontory certainly not more than twenty feet in height and a good three hundred yards distant. To the left the cliff rose still higher, terminating in a projecting crag a full two hundred feet above the sea. "We'll be with you in half an hour," he shouted. "Right-o; no immediate hurry," replied Dick cheerfully, for knowing that help was at hand his spirits rose accordingly. "What a ghastly spot," declared Beverley, as the men cautiously made their way round in the direction of the shelving promontory. "Looks as if there had been a volcanic eruption here not so very long ago." "Centuries ago, perhaps," replied Villiers. "Lack of vegetation doesn't help us much to fix a date. I'd like to explore this show in broad daylight." "We may have to," added Bobby. "How we are going to get that kid back to the ship in the dark puzzles me. We'd possibly find ourselves bushed." "It's a sad heart that never rejoices," quoted Jack. "Main thing is we've found your brother. Sprained ankle's nothing. Wonder what he meant when he said he was pushed? Look out--that's a nasty one." He pulled up just in time to avoid a deep and narrow fissure that ran practically at right angles to the general trend of the cliffs. "We can scramble down that," decided Bobby, "and save a long detour." "And perhaps find ourselves stranded on the next terrace. I'm not having any, old thing. If you want to indulge in a sprained ankle just to show sympathy to your brother, then that's your funeral." Beverley saw the force of the argument. "Right-o," he replied simply; but it occurred to him that for once at least the two chums were exchanging characteristics. He was usually cautious, while Villiers was of a boisterous, go-ahead nature. Now Villiers displayed caution, while he, Beverley, was decidedly impulsive. "I'd do it like a shot," continued Jack, "if there were any pressing necessity for it, but there isn't. Dick is in no immediate danger. If we slipped then Harborough would have three useless people on his hands. Stand by with that lamp." Guided by the beam of light Jack jumped the intervening gap, adroitly caught the bulky apparatus, and waited until Bobby had safely crossed the crevice. Beyond that point progress was comparatively simple, and presently they found themselves on the sandy shore of the lagoon. "Let's see the extent of the damage, Dick," said his brother, when the rescuers arrived at the shelving ground where the injured lad lay. "Nothing much," declared Dick. "Ankle twisted. It's quite all right when I don't move; when I do it gives me what-oh!" Bobby was busy wrapping handkerchiefs soaked in salt water round the swollen limb. "Tell us what happened," he invited.
