No one on board the houseboat noticed the approach of Tom's motor launch until he blew the automatic whistle. Then, with one accord, the four girls rushed to one side of the boat. They made frantic signals, then all began to talk at the same time.

"What's up? Where's your tug?" demanded Tom. "Here you are, as peaceful as clams, while we have been scouring the coast for you."

"Don't scold, Tom," laughed Madge, "and don't refer to us as clams. We are stuck in the mud. Our wretched little tug brought us too near the shore, piled us up here and then went away two hours ago for help. We were so afraid you would go on without us. What can we do?"

While the girls talked Tom, Jack and David had been quietly at work. They had secured the houseboat to the launch by means of their towing ropes. Tom put on all speed. His motor launch tugged and strained forward. The "Merry Maid" did not move. She was a fairly heavy craft, with her large cabin and broad beam. Miss Betsey Taylor and Miss Jenny Ann joined the crowd of anxious watchers on the houseboat deck. Instead of gliding up a peaceful river, gazing at fruitful orchards and lovely old Virginia homesteads through the oncoming twilight, the houseboat crew would have to remain ignominiously on a sand bank until a larger boat came along to pull her off.

Tom tried again. Once more the "Sea Gull" went bravely forward—the length of her towing rope.

The girls were almost in tears. Suddenly Madge laughed. Eleanor and Lillian looked at her reproachfully.

"I don't see anything to laugh at," expostulated Eleanor.

"I don't either, Nellie," agreed Madge. "We ought to cry, we are such geese. Tom! David!" she cried. "You have never pulled up our anchor. Of course we can't get off the sand bank. We forgot to tell you that the captain on the little tug anchored us here to keep us from drifting away. I am so sorry."

In a little while Tom Curtis's motor launch, followed by the "Merry Maid," entered the Rappahannock from the Chesapeake Bay. It was Tom's intention to tow the houseboat along several of the Virginia rivers during their vacation. It looked as though they might have a peaceful excursion with nothing to mar its serenity. But there were five boys and four girls aboard the boats, besides the two older women.

The voyagers did not journey far the first day. It was about sundown when they came along shore near a wonderful peach orchard and it was here that they decided to spend the night. The crew of the "Merry Maid" entertained the crew of the "Sea Gull" at dinner, the young folks spending the evening together. As Tom was about to bid Madge good night she said almost timidly, "Thank you so much, Tom, for being so good to David. I hope he hasn't disappointed you?"
