Dick began to think about Carrie as he set out across the flats. He liked her much, and admitted that it cost him an effort not to fall in love with her; Carrie had made him feel that this could not be allowed. Sometimes he wondered why, and sometimes he thought he knew; but then he suspected that Jim would marry Evelyn. Dick approved Jim, but doubted if he was altogether the man for Evelyn. Perhaps, however, when he came to think about it, he really meant that Evelyn was not the girl for Jim. There was a difference——.

He pulled himself up. He was fond of Evelyn, although he knew her faults; besides, the fog was thick and he must keep his proper course. He ought to strike the big gutter soon and was anxious about the tide: it would soon run up the hollows in the flats. He wondered where Mordaunt was, because Lance had told him he was going out on the sands and he had not heard his gun.

Shortly afterwards, Dick went down the bank of the gutter and began to wade across. The water did not come much above his ankles; but it was moving; slowly yet, although it would soon run fast. He got across and saw Jim's punt on the muddy sand. The fog was low and drifted about in belts, clearing now and then, and when he stopped by the punt the moon shone through.

Dick was puzzled. The punt had been moved since Jim pulled her up the bank. It was prudent to leave her where one could get on board when the tide rose, but Dick could not see why Jim had afterwards moved her down. He had, however, done so, because the rollers he used had made a rut in the sand in advance of her present position. Then the anchor had been carried up to higher ground, for one could see where the line had dragged, although it now lay close to the punt. Dick began to examine the footsteps about the spot. He was something of a naturalist and a good wildfowler and had studied the tracks of animals and birds.

Jim had obviously come up the gutter and another man had joined him. The other was barefooted and the marks seemed to indicate that he had helped Jim to run down the punt. Then a third man had arrived and Dick thought this was Lance, because he wore nailed fishing brogues. Lance often used brogues; he was cautious and did not like soft mud. Dick imagined Lance had reached the spot after the others and was somewhere about; he would not go far from the gutter when the tide was rising. The thing was strange, but since Jim had moved the punt back, there was no reason why Dick should meddle. Jim had probably gone to the scar and no doubt knew how long he could stay. Moreover, Dick's business was to find Carrie, and he set off again.

He followed a small creek that joined the big gutter. Its channel was narrow and cut rather deep into the sand. Although a belt of fog rolled up he could see fifty or sixty yards, and presently distinguished a hazy figure near a bend of the creek. He thought it was about Lance's height, and shouted; but the fellow did not answer and vanished next moment. It looked as if the fog had rolled nearer and hidden him, although he might have gone down into the creek. Dick went to the edge, but saw nobody, although he crossed a row of steps. This was puzzling. He imagined the other had heard his shout and was in the hollow, where his shooting-clothes would melt into the background. The sand, however, was soft and the marks had begun to fill up. Dick did not see why he should follow them, since the man might have meant to hide until the geese flew over. He gave it up and pushed on.

The fog crept towards him and did not look as if it would soon roll away. For all that, he knew the sands and had the noise of the advancing surf for a guide, which was lucky because speed was important. A stream ran through the flats near the other shore, and if Carrie and Jake had started they would have crossed its channel and now be on the long peninsula of sand that went up the middle of the bay. When the water rose they could not get across the main gutter, and it would be hard to reach the land from the end of the peninsula because it was traversed by a number of little creeks, up which the tide forced its way.

After a time, Dick stopped and fired the gun. He heard nothing but the echoes that rolled across the waste and the roar of the sea. The latter was ominously loud and he began to run. When he had gone some distance, he tried another shot and disturbed two black-backed gulls that made a noise like hoarse laughter as they flew overhead. This was all, and he felt that the gulls were mocking him. He was getting anxious, and ran on until he was forced to stop for breath, as the fog began to lift. It rolled back before a little puff of wind, the moon shone through, and he saw glittering water in front.

Dick began to run the other way. He could do no more, and it looked as if Jake and Carrie were not on the middle sand. After all, he had not much ground for imagining they had meant to cross the bay; if there was no room at the village, they might have walked to a station four or five miles off and gone to the market town. He must save himself, and since he hardly thought he could reach Jim's punt before she floated, he headed up the middle sand. One could cross the gutter farther on, if one knew the right spot, but it would mean wading some distance and he must be quick. He got through, and then ran back along the edge of the channel. He wanted to see if Jim had returned to the punt.
