He must now grapple with a fresh problem. The _Rowan_, drawing little water when her centerboard was up, would shortly be afloat. Andrew had not laid out an anchor, for it might be dangerous. If the anchor failed to hold, she would sheer across the current before her keel was quite off the bottom, and the leverage of the taut chain might help the rush of water to press her down into the sand or roll her over. One could take no chances with the Solway tide. Still, if left unmoored, she would drive across the flats, away from his comrades.
Whitney could not determine what to do; and while he waited in tormenting indecision, the boat rose upright and the water swirled furiously round her bilge. Then his heart leaped as a cry came out of the dark, and soon afterward two indistinct figures appeared at the side of the gut.
"Be quick! She'll be off in a moment and the anchor's on board," he shouted, pulling up the dinghy to row across.
"Stay where you are!" Andrew called. "We can wade it. In with you, Dick!"
They were soon knee-deep and Whitney saw the current boil about their legs when they stopped as the water got deeper, but Andrew encouraged Dick, and they went on again and reached the yacht. Dick was panting, but Andrew seemed quite cool.
"I don't know about the anchor yet; we'll wait," he said, and stood watching the tide ripple past.
"It was lucky I met Andrew when I lost the channel," Dick said to Whitney in a resentful tone. "You might have waited for me."
"Hold on, Dick," interrupted Andrew. "Perhaps you'd better go below and change your clothes."
Dick left them; and soon afterward the boat began to move uneasily.
"The stream's getting slack; the water must be coming through from the other end," Andrew said.
In another minute she slowly floated away and he threw the anchor off the bow.
"She'll ride to it, but as we needn't make sail until the flats are covered, we'll go down and get supper."
He changed his clothes while Whitney lighted the stove.
"How did the lamp go out?" he asked presently.
Whitney related his adventures, and Dick turned to him with a smile.
"Sorry I was huffed, but I dare say you can make allowance for my feelings. They'd got rather harrowed while I wandered about in the dark. You did the right thing, of course, in going back."
