"Give him a shove," said Jake, addressing Frank. "When he gets up on deck, pitch him in."

Frank turned toward the dog, and then stopped abruptly when it showed its teeth and growled.

"It looks as if he meant to go along," Jake remarked with a grin. "Prod him with the boathook if he won't move."

Frank was dubious, as he imagined the dog might resent the prodding. At that moment Harry, who had been too busy to notice what was going on, hauled up the weather sheet of the jib.

"I'm clear," he called to his father. "I'll cant her head to lee when you're ready."

Mr. Oliver put the helm up as the bows swung around, and when the sloop slanted over Jake made a futile grab at the dog. Then shouting to Frank, he dropped into the canoe and clutched the rail as the sloop forged ahead, but the boy was busy with the mainsheet and did not look up. In another moment Jake let go. Almost immediately afterward the sloop came round, and when she stretched away toward the mouth of the cove the canoe dropped astern.

"Stand by your jibsheets," called Mr. Oliver. "We'll have to come round again."

They were very busy during the next few minutes, for the cove was narrow and the wind was blowing in. When at length they swept out into the open water the dog crawled up to Harry and licked his hands. Harry looked at his father, who made a little sign of assent.

"I suppose he'll have to stay," he sighed. "When that dog decides on doing anything it's wise to let him do it. Now we'll square off the mainboom."

They let the sheet run until the big mainsail swung right out, and the sloop drove away, rolling viciously. Short, foam-flecked seas came tumbling after her, but as the tide was running the same way under them, lessening the resistance, very few broke angrily. Frank had learned enough by this time, however, to realize that it would probably be different when the stream turned. In the meanwhile the boat was sailing very fast, with a little ridge of frothing water washing by on either side when she lifted, and a thin shower of spray blowing all over her. Now and then the great sail with the heavy boom beneath it swung upward in an alarming fashion. Frank noticed that Mr. Oliver's eyes were gazing intently before him, and that his hands were clenched tightly upon the tiller.
