All four ran to look over the rail of the upper landing, and saw a strange-looking craft anchored at the dock. On the dock were two boys and Mr. Hickox; the latter gentleman apparently much excited and interested.

"It's Jack Harris!" cried Leicester, "and another fellow with him; and, oh, I say, girls, they've got a motor-boat!"

"What's a motor-boat?" cried Fairy; but as all four were then flying down the steps at a rapid speed, nobody answered her.

Wondering who the second boy could be, and filled with delightful curiosity as to the wonderful motor-boat, the Dorrances reached the dock with astonishing rapidity.

"Hi, Jack," cried Leicester, "thought you were coming up by train. What a dandy boat! Yours?"

"No," said Jack, whipping off his cap, and shaking hands with Dorothy; "it belongs to my chum here, Bob Irwin. I've brought him along, Dorothy, and I hope you can take us both in. Less said you had plenty of room. I would have written, but Bob only decided to come at the last minute, and we were so busy and excited getting the boat off, that I forgot to telegraph, though I meant to do so."

Bob Irwin was a big, jolly-looking boy, of about seventeen or eighteen, and his smile was so broad and comprehensive that the Dorrances felt acquainted at once.

"Indeed we have plenty of room," said Dorothy, answering young Irwin's greeting; "and we're very glad to have you both,—and your boat too," she added, still looking with a sort of fascination at the trim little affair.

"She is a jolly little craft," said Bob Irwin, frankly; "I've only had her a few weeks. I named her Shooting Star, because she goes like one. We came all the way up from Jersey City by the canal."

"All the way!" exclaimed Lilian; "what fun you must have had coming through the locks!"
