After they had trimmed sail Frank sat still for a while to recover his breath and, if possible, his composure. He felt that it was necessary to demand an explanation from his companion. Though they had once or twice had a difference of opinion, this was the first time that Harry had been insulting, and Frank found it impossible to pass over what he had said. When he felt able to speak clearly he looked his companion in the eyes.

"Now," he began, "I'll admit that you can shoot and sail a boat rather better than I can, but that doesn't entitle you to talk as you did just now."

"I don't know if it matters, but I've a notion that I did shout," Harry answered calmly.

"That only makes it worse," Frank burst out warmly. "You couldn't call it shouting either. I once heard a coyote on the prairie, and it had a much sweeter voice than you have."

To his astonishment, Harry grinned.

"Oh, well," he said, "but won't you get down under the mainboom before you go on? I don't want those fellows astern to see there are only two of us on board the sloop."

Frank did as he suggested, whereupon Harry waved his hand and smiled graciously.

"Now," he added, "you can go ahead."

Frank found it harder than he had expected. His anger was beginning to evaporate and Harry's good humor was embarrassing. Still, he made another effort."In the first place," he resumed, "there are just as smart and capable folks in Massachusetts as there are anywhere else."

"That's quite right," assented Harry. "I don't see why there shouldn't be, but I suppose you're not through yet. You want to call me down?"

"When you say things of that kind—you—" Frank stammered, and stopped when he observed his companion still smiling.

"Sure!" said Harry, "I ought to be pounded with the boathook if I'd meant them."

Frank gazed at him in bewilderment. "You didn't mean them?"

"No," said Harry. "Not a word of it."

"Then why did you say them?"

"Well," replied his friend, "that's a reasonable question. Now it was mighty important that you should get alongside before our friends astern came into sight, and though you weren't making very much progress it seemed to me you were doing all you knew."

"I was," Frank assured him.

"Still, I had an idea that if I could make you jumping mad you might do a little more. It's hard to tell what you're capable of until you're real savage, and I thought I'd whip you up a bit where you were most likely to feel it."

Frank's indignation vanished, and he changed the subject with a laugh.

"Do you think those fellows suspected anything?" he asked.

"No," said Harry. "They were too busy getting sail on her to notice exactly how far ahead we were when we ran out of the bay, and it will probably only strike them that they're not quite so far astern as they expected. All we have to do now is to lead them along toward Bannington's. I'd rather keep them sailing than have them prowling round the depot asking questions and, perhaps, sending telegrams, and I've a notion we can leave them when we like. She's drawing away from them now and we've only a small jib on her."

His surmise proved correct, for an hour later the other boat had diminished to a dusky patch of sail far astern. Dusk soon commenced to fall and the wind seemed to be freshening, but as they swept around a rocky point Harry changed his course and told Frank to make a stout rope fast to the bucket and pitch it over.

"It will hold her back and let the other fellows come up," he said with a grin. "They'll probably figure their boat's faster in any weight of wind, and we don't want to run out of sight of them."

It grew dark and for a while the sky was barred with heavy clouds until the moon broke out, when they saw the pursuing craft sweeping up close astern in the midst of a blaze of silvery radiance. She had now, however, a mass of canvas swung out on either side of her, and Frank wondered what sail she was carrying.

"They've boomed out a jib as a spinnaker," Harry explained. "I don't see why we shouldn't do the same, particularly as it will make them keener on following us to Bannington's. One of them means to go south with the steamer if dad gets on to her. Now we'll heave in that bucket, and when it's done they'll open their eyes."

It was not easy to haul in the bucket. Indeed, once or twice it was nearly torn away from them, but at length they accomplished the task.

"It's awkward running a boat with a spinnaker unless you have a crew," remarked Harry with a somewhat puzzled look. "Still, I feel we ought to give those fellows a run for their trouble and I can't get clear of them with only the mainsail drawing. A jib set in the ordinary way is no use when you're before the wind."

The other boat had drawn almost level with them and came surging along some forty yards away, rising and falling, with the foam piled up about her bows, and a great spread of canvas that swung up and down as she rolled on either side.

"Hello!" shouted Harry. "Where are you going?"

"North," was the laconic answer.

Harry chuckled as he turned to Frank. "Well, as dad will be in Everett by this time, I don't see why they shouldn't come along with us as far as they like, but we'll let them draw ahead before we get up the spinnaker. I'd rather they didn't notice I had to set it alone."

The other boat forged past them, and she was growing dim ahead when Harry pulled out a bundle of canvas from beneath the side deck.

"It's an extra big jib we carry in light winds, but it makes a good spinnaker," he said. "You'll have to keep her straight before the wind, because it's a mighty awkward thing to set."

Frank took the helm and watched his companion as he shook the big sail out all over the boat, after which he led a rope fastened to one corner of it through a block at the end of a long spar that lay along the deck. He thrust this out over her side and made its inner end fast to the foot of the mast.

"A spinnaker boom always goes forward of the shrouds and you lead the guy aft outside them," he said. "Get hold of it and stick fast. It's easy so far, but in a minute the circus will begin. You want two pairs of hands to set a spinnaker in a breeze of wind."

Frank glanced at the short seas which surged by, glittering in the moonlight flecked with wisps of snowy froth, and it struck him by the way the boat swung over them with the foam boiling about her that she was carrying sufficient canvas in her mainsail. Then Harry, calling to him to mind his steering, hauled on a halliard and a mass of thrashing canvas rose up the mast. It blew out like a half-filled balloon, lifting up the boom, which was run out on the opposite side to the mainsail, and seemed bent on soaring skyward over the masthead. After that the boom swung forward with a crash, the mast strained and rattled, and Frank feared that the great loose sail would tear it out of the boat. He saw Harry lifted off his feet and flung upon the deck, after which the forward part of the boat was swept by flying ropes and billowy folds of canvas, among which his companion seemed to be futilely crawling to and fro. Presently his voice reached Frank hoarse and breathless.

"Haul on the guy!" he cried. "She'll pitch me over or whip the mast out if this goes on."

Frank dragged at the rope with all his might, but he could not get an inch of it in, and he dared not take his right hand off the tiller for fear of bringing the big mainboom over upon the spinnaker, which would probably have caused a catastrophe. Indeed, he fancied that one was inevitable already, since it seemed impossible that Harry could control the big loose sail which was now wildly hurling itself aloft.

"I can't move it!" he shouted.

Harry came aft with a jump and grasped the guy.

"Now," he said, "together! Get both hands upon it. Hold the tiller with your elbow."

For the next half minute there was a furious struggle, and as the boom went up again Frank felt that they were beaten. His companion, however, hung on desperately, panting hard, and by degrees the boom swung down and back across the boat and the sail flattened out.

"Make fast!" cried Harry breathlessly. "I can manage the sheet."

He floundered forward to the foot of the mast, and when he came back the spinnaker was drawing steadily and the sloop had changed her mode of progress. She no longer rolled viciously or screwed up to windward as she lifted on a sea, but swayed from side to side with a smooth and easy swing, and Frank could steer her with a touch upon the tiller. In spite of that, steering was ticklish work, for the mainboom and the spinnaker boom went up and came down until they raked the glittering brine alternately, and Frank realized that it would be singularly easy to bring one crashing over upon the other. There was no doubt that the boat was sailing very fast, and he hazarded one swift glance over his shoulder at the canoe. She was surging along astern, hove up with her forward half out of the water, and a seething mass of foam hiding the rest of her. Harry, however, glanced forward somewhat anxiously.

"That boom's lifting too much," he said. "One of us ought to sit on it. Do you feel able to steer her?"

Frank said that he believed he could manage it.

"Well," said Harry, "if you jibe either sail across you'll either pitch me in or break my leg, even if you don't roll the boat over. Sing out the moment you feel her getting too hard upon the helm."

Scrambling forward, he crawled out along the spinnaker boom, to which he clung precariously, lifted up high one moment and the next swung down until his feet were just above the foam. Sometimes they splashed in, and Frank, bracing himself until every nerve was strung up, felt horribly uneasy. In spite of that, the wild rush through the glittering water which boiled about the boat was wonderfully exhilarating. She seemed a mass of straining sail which swayed in the moonlight above an insignificant strip of hull half buried in snowy foam. Over her black mainsail peak dim wisps of clouds went streaming by, and from all around there was a tumult of stirring sound—the clamor at the bows, the swish of water as the canoe came charging up to her, and the splash of tumbling seas. Everything ahead, however, was hidden by the sail, and he was wondering where the other boat was when Harry called to him.

"Slack the guy a foot or two and let her come up a little. Don't let it get the run of you or you'll pitch me in."Frank was very cautious as he eased the rope out around a cleat, after which, when the spinnaker boom had drawn forward, he found that he could luff the boat. When she had swerved from her course a trifle he could see the other boat close ahead, and it gave him some idea how fast both craft were traveling. She seemed nothing but sail. Indeed, except for the torn-up track of foam that marked her passage, she looked much less like a boat than some wonderful phantom thing flying at an astonishing speed across the sea. Swiftly as she sped, however, there was no doubt that the sloop was creeping up on her, and Frank felt himself quivering all through as the distance between them lessened yard by yard. Then suddenly the contour of her canvas changed and she swung around from leeward across the sloop's bows. Frank's heart gave a sudden leap as he wondered what he must do and his nerve almost deserted him, until Harry called again.

"More guy!" he sang out. "They're trying to luff us. We must keep their weather."

Although fearful that it might overpower him, Frank slacked the guy out inch by inch, and as the sloop came up a little farther he saw the whole of the other boat again. The sloop's bowsprit was level with her quarter. She was scarcely a dozen yards away, leaping, plunging, swaying through a flung-up mass of foam, but they were steadily drawing up with her, and the boy could have shouted in the fierce excitement of the moment. Two or three minutes later they were clear ahead. He could no longer see the other boat, and he dared not risk a glance back at her. Indeed, it was a relief to him when Harry came scrambling aft.

"We'll get that guy in again," he said. "Unless something gives out, those folks won't catch us up."

They had a desperate struggle with the guy, but Harry laughed gayly when they had made it fast.

"They'll follow us on to Bannington's, sure," he said. "We should be there in half an hour, and I don't mind allowing that I'll be glad to get some of this sail off her."

After a while a black bank of cloud spread across the moon, and Frank wondered anxiously how much of the half hour had gone. He had now only the pull on the tiller to guide him as they drove on furiously, and the strain of concentrating all his faculties on his task was beginning to tell on his strength. Once or twice he imagined that he came perilously near to bringing the mainboom over, and he would have called Harry to the helm if he had felt certain that he could cling to the slender lurching spar as well as his comrade could. He was getting nervous, and the seething rush of water past the boat was becoming bewildering.

At length, however, he made out a dark and hazy mass over the edge of the mainsail, which he supposed was land, and in another few minutes a blinking light appeared. He called to Harry, who merely twisted himself around on the boom with the object of looking out beneath the sail and then told him to keep her heading as she was. After that the land rose rapidly, growing blacker, and a second light appeared. This was closer to them and Frank, thinking he saw it move, noticed a green blink beneath it.

Presently both lights disappeared behind the sail, and some minutes later Frank almost let go the tiller as the deep blast of a steamer's whistle rang out close ahead. On the instant Harry swung himself down from the boom.

"Let go your guy!" he shouted. "Down helm; get the mainsheet in!"

Frank could never clearly remember all that followed in the next two or three minutes during which he was desperately busy. He let the spinnaker guy run, and the big sail which heaved up the spar beneath it swung wildly forward. Then he shoved down his helm, and the mainboom slashed furiously as the boat came up toward the wind. The sheet blocks seemed to be banging everywhere about him as he hauled at the rope, and he could hear nothing but the savage thrashing of loosened canvas. Harry was struggling forward with a mass of billowing sail that threatened to sweep him off the narrow deck, while flying ropes whipped about him. Presently, out of the din, there rose another sonorous blast of the steamer's whistle.

The next moment Frank saw her, heading, it seemed, straight for them, blazing with tiers of lights, and in almost nerveless haste he pulled up his tiller. The bolt fell off, he saw Harry flung down with the spinnaker rolling about him, and he scarcely dared to breathe as the rows of lights ahead lengthened and the black wedge of the steamer's bows faded from his sight. It was now her side he was gazing at, and it was evident that she was swinging around. In less than another minute she had forged past them, and leaving the helm he scrambled forward to aid his companion. For a moment they had a brief struggle with flying ropes and billowing sail, and then they clambered back into the well, where Frank sat down with a gasp of fervent satisfaction.

"Well," he panted, "I'm glad that's over, and you had better take the helm. I've had enough."

Harry glanced toward the steamer, which was growing less distinct.

"A close call!" he remarked. "It looked as if she was going slap over us. I couldn't see her sooner because of the sail. She's running into Bannington's."

They heard her whistle a little later, but they were then close in with a shadowy point of land, and looking back Frank made out a faint blur on the water far behind them which he knew must be the other boat. When he pointed it out Harry laughed.

"They can't see us against the land, but I've an idea they'll be in soon enough to learn the steamer didn't pick one of us up," he said. "That will start them wondering why we drove her so hard and where we've gone. Now you had better get the stove lighted and the supper on."
