"We'd better get there first," went on Captain Ross, still chuckling at his riddle. "Cast off, Bunker Blue!"
Bunker loosed the ropes that held the Fairy to the wharf, and the boat slowly drifted away.
"Oh, we've really started!" cried Sue, as she saw the open water between the rail and the string-piece of the wharf.
"We'll go faster than this!" exclaimed Bunny. "Wait till Bunker Blue starts the motor."
As there was not enough wind to allow the sails to be used, it was needful to start the motor, and soon it was chugging away, sending the Fairy swiftly along through the water.
Bunny and Sue were delighted with the trip. They sat in camp-chairs on deck and watched the different sights. They expected to cruise about on the boat for perhaps three days before going to the Cove. They could sleep in the little bunks with which the boat was provided.
"It's a funny way to go to bed," said Sue, after looking at the bunks for the tenth time.
"Well, I guess you can sleep here just as well as at home," answered her brother.
"You'd better not walk in your sleep, Bunny, 'cause you might walk overboard."
"I ain't going to walk in my sleep any more," answered Bunny. "I told daddy I wasn't."
