Whitney frowned as he looked about. He could see nothing except the black line of the bank a few yards away and the beam from the lighthouse on Southerness, though this had grown less distinct. There was no fog, but the air was filled with an obscuring moisture that wet his face and gathered upon the dinghy. Since the Rowan's canvas had been lowered she would be hard to see, and she lay at some distance from the water. He could not remember how long it was since he had seen the light, but it must have been some time, and he blamed himself for not keeping an eye on it.
Still, he ought to find the gutter near which she lay, and he knew the bearing of the Southerness light from there. He had guessed its distance, and if he took a new bearing now, the angle between it and the other would give him the length of the line he must follow to reach the neighborhood of the yacht. Taking out a small compass, he struck a match, but it went out. His hands were wet and the box was damp. He tried two or three more with no better success, and when he got the last to burn, the knife-blade he laid across the compass cast a shadow on the card. This prevented his seeing the points; and finding that he had no matches left, he paused to think.
If his friends had returned to the boat, they would certainly not have put out the lamp, and it was disturbing to imagine their wandering about the sands, particularly as Andrew might have to cross some hollows up which the tide would shortly flow. Whitney shouted, but got no answer, and after waiting a few minutes he began to row, because it was plain that he must relight the lamp as soon as possible. He kept out in the channel to get the help of the stream, which he thought was running with him, but he did not seem to be making much progress, when he passed a projecting tongue of sand. Stopping to get his breath, he saw that the dinghy began to drift slowly back, and this disturbed him. The tide had turned sooner than he expected.
Heading in toward the bank, he rowed savagely; but the flat-bottomed craft did not pull well. Her main advantage was that she could be folded up and stowed on deck. After a time bits of seaweed and flakes of scum drifted up to meet him, and he could hear the water ripple along the edge of the sand where the channel bent. The flood was beginning to run and he had not covered much distance yet. Sweat dripped from his face, his back ached and his hands blistered; but this did not matter. Dick should be able to follow the channel down; but Andrew was no doubt a long way from land, with his retreat to the beach perhaps cut off. Moreover, Whitney saw that his own position was not fortunate.
He had the dinghy, but her side was only a foot above the water and the tide would presently sweep her up the Firth. He could not row against it long, and the current would capsize or swamp the boat if he struck a shoal. Still, it would be slack for about an hour and he must make good use of the time. His arms got stiff, but he kept up the pace and edged inshore until he touched bottom, when he made a deep stroke. The temptation to turn round and look ahead was strong, but he resisted it. He must not relax his efforts for a moment. He ought to see the mouth of the gutter when he had gone far enough. Unfortunately, however, the edge of the bank began to be indented by shallow bays, and, as he must pull straight across in order not to lose time, their ends were not always visible. It was unthinkable that he should overshoot the gutter, but he imagined it was still some distance off.
At last he saw a bold ridge of sand that looked like the place where they had launched the dinghy, but on pulling close in, he could not distinguish the mark she must have made as they dragged her down. He rowed on for a hundred yards and stopped. There was no gutter, though he believed he had come far enough. The sound of the surf was ominously loud and a black-backed gull that fluttered overhead seemed to mock him with its hoarse, croaking laugh.
Whitney felt unnerved; but he pulled himself together. His friends' lives, and perhaps his own, depended on his keeping cool. He must have passed the gutter, but he might see the Rowan from the top of the bank. Running aground, he pulled the dinghy out. There was no grapnel, but she had a few fathoms of painter and he tied it to an oar, which he drove into the sand. This ought to hold her if she floated before he came back.
For a few minutes he walked rapidly away from the water, then turned and ran along the flat, but could not see the yacht; and when he dared stay no longer he came down to the channel. There was nothing that looked like the mouth of the gutter and the dinghy was afloat. Pushing off, he rowed a short distance and made another unsuccessful search. Whitney was now getting desperate, but he tried to think calmly what he should do. He could fold up the dinghy and carry her toward the Southerness light, shouting as he went; but the others would be in very grave danger if he missed them; besides, they would not both come the same way. The plan would not serve; he must try again to find the Rowan. Progress was difficult against the current; but he did his best, and landing again, he dragged the dinghy up. She would not float for some time because the bank was steep, but he dared not go far, lest he should lose his way in coming back.
Striking shoreward, he plowed breathlessly through soft sand, but saw nothing for some minutes. Then, when he was despairing, a black object emerged from the gloom. It might be only a hummock; but after he had gone a few yards, he knew it was the yacht and felt a thrill of relief that was unnerving in its keenness. Still, he must brace himself and decide between two courses. The dinghy might be needed to take his comrades off, and there was a risk of her going adrift before he got back; he ought not to lose a moment in returning to her. On the other hand, Dick and Andrew must be in danger of being cut off by the advancing tide and the lamp would show them where the boat lay; but it might take some time to light. Hesitation would be fatal: he must do one thing or the other at once.
Running to the yacht, he clambered on board and unfastened the lamp from the stay, and then groped about the cabin for matches. At last he found some and, shaking the lamp, heard the oil splash inside. The wick did not ignite readily and he had to rub the charred edge off, but by and by the flame began to spread and he scrambled on deck, striking his head against the hatch. When he reached the bow, he found himself shaking and scarcely able to tie the lamp to the stay, but he jumped down on the sand and ran with all his speed toward the channel. He could not see the dinghy and feared that she had gone, but he found her safe, afloat and straining at the rope.
