Merefleet glanced at her helplessly. He did not think she realised the gravity of the situation, but something in the little smile that twitched her lips undeceived him.

"The sea was full of boats a little while ago," he said. "They have probably gone in for the lunch hour. But they will be out again presently. We shall have to drift about for a while and then run up a distress signal. It will be all right."

She nodded to him and laughed.

"Splendid, Big Bear! You talk like an oracle. I guess we'll run up my red parasol on the end of an oar for a danger sign. Bert could see that from the terrace." She glanced shorewards as she spoke, and he saw her face change momentarily. "Why," she said quickly, "I thought we were close in. What's happened?"

Merefleet looked round with sullen perception of a difficult situation.

"The wind is blowing off shore," he explained. "It was north when we started. But it has gone round to the west. It will be all right, you know. We can't drift very far in an hour."

But he did not speak with conviction. The sea tumbled all around them, a mighty grey waste. And the shore seemed very far away. A dismal outlook in truth. Moreover it was beginning to rain.

Mab sheltered herself under her sunshade and began to laugh. "It's just skittles to what it might be," she said consolingly.

But Merefleet did not respond. He knew that the wind was rising with every second, and already the little boat tipped and tossed with perilous buoyancy.

Mab still held the rudder-lines. She sat in the stern, a serene and smiling vision, while Merefleet toiled with one oar to counteract the growing strength of the off-shore wind. But she very soon put down her sunshade, and he saw that she must speedily be drenched to the skin. For the rain was heavy, drifting over the water in thick, grey gusts. They were being driven steadily eastwards out to sea.
