"How could I, when he was rigged up so different, with his head all covered up?" replied Hasbrook, impatiently. "The man was about the captain's height, but stouter."

"He was dressed for the occasion," added the sheriff, as he walked to the shore, where the skiff lay.

They dragged it down to the water,—for it was low tide,—and got into it. Beardsley had traced to the cove the print of the heavy boot, which first appeared in some loam under the window where the ruffian had entered Hasbrook's house. He found it in the sand on the shore; and he was satisfied that the perpetrator of the outrage had arrived and departed in a boat. He had obtained from the captain's boot-maker a description of his boots, but none corresponded with those which had made the prints in Northport and Lincolnville.

At the cove all clew to the ruffian had been lost; but now it was regained.

The sheriff paddled the skiff out from the shore in the direction of Seal Island. The water was clear, and they could see the bottom, which they examined very carefully as they proceeded.

"I see it," suddenly exclaimed Hasbrook, as he grasped the boat-hook.

"Lay hold of it," added the sheriff. "I knew I was right."

"I have it."

Hasbrook hauled up what appeared to be a bundle of old clothes, and deposited it in the bottom of the skiff. Mr. Beardsley had worked up his case very thoroughly, though it was a little singular that he had not thought to ask Donald any questions; but these investigations had been made when the boat-builder was at home all the time, and the detective did not like to talk about the case any more than was necessary. He had ascertained that Captain Shivernock wore his usual gray suit when Donald saw him after the outrage, and he came to the conclusion that the ruffian had been disguised, for Hasbrook would certainly have known him, even in the dark, in his usual dress. They returned to the shore; and the bundle was lifted, to convey it to the beach.

"It is very heavy," said Hasbrook. "I suppose there is a rock in it to sink it."
