"That's Southerness; they'll light up, soon," Andrew said. "I know one of the light-keepers and I'll walk across and ask him about the entrance to Rough Firth. There's a flock of duck up the channel, Jim, and you might get a shot at them from the dinghy when it's a bit darker. Will you stay on board, Dick?"
"Not much! There's nothing more melancholy than sitting alone in a stranded boat. I'll go with Jim."
Andrew went below and trimmed the anchor-light; then fastened it firmly to the forestay, and set off across the sands. Half an hour later, Dick and Whitney carried the small, folding dinghy to the channel and pushed her off. The current was now slack and they made progress until Dick shipped his oars and, kneeling down, took up the small hand paddles; but he let her drift for a few moments while they looked about. It was dark and the shore-line had faded, but some distance up the channel a small black sail was visible across the bank, and a steady bright beam marked the Southerness lighthouse. Half-seen birds were wading about the water's edge, but Dick said these were oyster-catchers and not worth powder and shot. A curlew's wild whistle fell from overhead and the cry of a black-backed gull came out of the obscurity like a hoarse laugh. It was rather dreary; and their clothes and the dinghy were getting damp; so, dipping the paddles, Dick drove the boat ahead.
After a while they distinguished a cluster of small dark objects some distance in front, and made toward them cautiously. The ducks did not seem to get much plainer, and Whitney thought they were swimming away. Stopping a few minutes to allay suspicion, Dick paddled again; but the ducks vanished as they crept on. Then he turned in toward the bank and pushed the craft along the bottom, hoping the dark background would hide their approach. Presently they saw the ducks again and Whitney raised his gun.
There was a red flash, smoke blew into his face, and the air was filled with the clamor of startled wildfowl. Still, they had heard a splash and Dick got out the oars and rowed ahead. As he picked up a floating mallard, they heard a flutter and knew there was a crippled duck not far off. Rowing out into the stream, they saw it rise awkwardly from the water. Whitney fired, and missed. After this, they spent some time in trying to get into range before he brought down the bird. Then they ran the dinghy ashore and Dick landed with his gun.
"I'll walk up the bank and try the soft places about the pools," he said. "If I don't turn up soon, it will be because I've gone back to the Rowan."
Whitney lighted his pipe while he waited to allow the birds to recover from their alarm, but he had to strike several matches because his hands were wet, and he was annoyed to find that he had not many left. It was very dark, and a cold wind was blowing. Whitney lay down on the floorings, for shelter and to hide the glow of his pipe. The birds were quiet, but a dull, throbbing roar came out of the distance, and he supposed it was the splash of the surf on the seaward edge of the shoals. When his pipe was empty, he got up, intending to step overboard and drag the dinghy down to the receding water; but he found that this was not needful, as the ebb had nearly run out. Paddling up the channel he heard the whistle of curlew, and for a time followed the invisible birds. He could not get a shot, and, deciding that he had had enough, he laid down the paddles. Hitherto, he had been looking ahead, but when he put the oars in the crutches he was facing aft.
Grasping the oars firmly, he looked for the twinkle of the Rowan's light. In his surprise he almost dropped an oar. The Rowan had disappeared.
