"What?" asked Mr. Ramsay, who had seated himself on a log on the wharf.

"You will lay down the keel of the boat for Mr. Rodman on Monday—won't you?" repeated Donald.

"Yes, if I am able; I don't feel very well to-day." And the boat-builder doubled himself up, as though he was in great pain.

The young man in the standing-room of the Sea Foam was Samuel Rodman, a schoolmate of Donald, whose father was a wealthy man, and had ordered another boat like the Skylark, which had been the model for the new yacht. He had come down to see the craft, and had been invited to take a sail in her; but an engagement had prevented him from going as far as Turtle Head, and the boat-builder and his son had returned to land him, intending still to make the trip. By this time Captain Patterdale had reached the end of the wharf. He went on board of the Sea Foam, and looked her over with a critical eye, and was entirely satisfied with her. He was invited to sail in her for as short a time as he chose, but he declined.

"By the way, Donald, did you see the green tin box when you were in my library this afternoon?" he asked, when all the topics relating to the yacht had been disposed of.

"Yes, sir; I saw you take some money from it," replied Donald.

"Then you remember the box?"

"Yes, sir."

"Did you notice it when you came out—I mean, when you left the house?"

"I don't remember seeing it when I came out," answered Donald, wondering what these questions meant.
