The owner of the bag examined the label.

"I know who put that on there," he remarked to himself, "well, I … why … no, I am going to the island, I suppose, to see a Mr. Kidd. Relation of the pirate, I hope. He didn't say anything about it in his letter. Whether he was related to Captain Kidd, I mean."

"You can find out tomorrer," said our skipper, "now we're headin' for Pingree's Beach to see if we can get a mess of clams of old man Haskell. Then we'll have dinner, and we can run over to the inlet at Little Duck in an hour, any time this afternoon."

The breeze was still light, and the "Hoppergrass" made only fair progress. Soon we were out of the river, and entering Broad Bay. The sun was high by this time, the air cool and pleasant. Everything seemed so clear and fresh, that it made us think the land a poor place in comparison with the water. How hot and dusty the streets of the town must be at this same minute! We felt sorry for the people who had to stay there. We had only the clean white hull of the boat between us and the sparkling water of the bay. Toward the sky the great white sail of our boat soared up, like the wing of a giant sea gull, and we went forward as easily and smoothly as one of the gulls who were gliding through the air, and dipping to the water a few hundred yards ahead of us. The grass covered river-banks were far astern now, and the only land ahead was some low sand-dunes and beaches, hardly to be seen in the distance.

"Here goes the chocolate," said Mr. Daddles, tossing it overboard, "once it might have saved my life, but I don't care for it now. Chocolate flavored with salt-water is pretty poor stuff."

"What made yer say p'r'aps this feller named Kidd was a relation of the pirate?" asked Captain Bannister. "You'd heard 'bout Fishback Island, hadn't yer?"

"No, I never heard the name, even."

"What about Fishback Island, Captain?" asked Ed Mason.

"You never heard all them yarns, an' all that diggin' that went on over there?"
