Shielded from the wind by the high sh.o.r.e, the dory sped on east by south. The island was over a mile long. When they emerged from the protection of the ledges on its eastern end they could see that the breeze had increased in force. Up to windward in the direction of Isle au Haut Bay occasional white-caps were breaking.

Spurling stopped rowing and took a long look around. Then he pulled off his sweater, settled himself firmly on the thwart, and braced his heels against the timber nailed across the bottom of the dory. His oar-blades caught the water with a long, steady stroke.

"We'll head north of the island," he said to Percy, after a few minutes of vigorous rowing. "The flood'll be running for the next three hours, and that'd naturally set us toward the north; but before we get to Tarpaulin the wind'll be blowing us the other way. We've got to allow for both."

Fifteen minutes went by, thirty, a full hour. Little by little Seal Island sank behind them and the familiar outlines of Tarpaulin loomed clearer and higher. The increasing breeze, blowing against the ocean current, kicked up a lively chop, on which the dory danced skittishly.

It took all Spurling's strength and skill to drive her onward.

At four o'clock they still had between four and five miles to go. The sea was alive with white horses. As the boat fell into the trough Percy momentarily lost sight of the island. He now recognized Spurling's wisdom in heading so far north of their goal. But for that they would inevitably have been blown off their course.

Jim was buckling to his task like a Trojan. Bare-headed, shirt open at the neck, sleeves rolled up above his elbows, he swayed to and fro, a tireless, human machine. His blades entered the rough sea cleanly and came out on the feather. Admiringly, almost enviously, Percy watched the play of the banded muscles on his brawny forearms. He would have given anything to be as strong as his dory-mate.

Past five o'clock, and still over two miles to the island. It was growing rougher every minute. The gale had fairly begun. It sheared the crests off the racing billows and flung them over the boat in showers of spray. Now and then a bucketful came aboard. It kept Percy busy bailing.

Occasionally Jim brought the dory head to the wind and lay on his oars to rest. After all, human muscles, powerful as they may be, are not steel and india-rubber.

"Pretty rough, isn't it?" said he, at one of these intervals. "Seasick, old man? You look a little white around the gills."

Percy shook his head. The situation was too serious for seasickness. In spite of the jocularity of his words, Jim's voice sounded hollow. Both of them knew that it meant a hard fight to reach Tarpaulin.

Silence, gray and leaden as the misty sky, settled over the dory.

Spurling was throwing all the strength he possessed into every stroke; Percy bailed continuously. It took considerably more than an hour to make the next mile and a half. A rainy haze, driving down from the north, had shrouded the island, and Brimstone Point was barely visible.

Jim's strokes were slower; they lacked their earlier force. His face showed the strain of the last hour. Uneasily Percy noted these signs of weariness.

"Tired, Jim?"

"Yes."

The brief monosyllable struck Percy with dismay. If Spurling's strength should give out, what would happen to the dory?

"Don't you want me to row awhile?"

"You can take her for a few minutes."

Scrambling forward, Percy grasped the oars and took Jim's place on the thwart. The latter lay down flat on his back in the bottom of the dory.

Apparently he was not far from complete exhaustion.

"Keep her up into the wind as well as you can," he directed.

Percy did his best; but he found it a hard job. The gale, now far stronger than the tide that flowed against it under the surface, was forcing them steadily southward. Brimstone Point could just be seen, a half-mile to the northeast.

Though he pulled his heart out, Percy could tell that he was losing ground, or rather water, every second. The wind mocked his efforts. He could not keep the boat on her course. Big rollers swashed against the port bow and broke aboard. Jim raised a drenched face, haggard with weariness, and took in the situation.

"Harder, Perce!" he urged. "Hold her up till I can get my breath. It's the ocean for us to-night, if we don't hit Brimstone."

Spurred by this exhortation, Percy jerked at the oars savagely and unskilfully. As he swayed back there was a sharp snap, and the starboard oar broke squarely, just above the blade.

Round swung the dory, head to the south. Up started Spurling with a cry of alarm, his fatigue forgotten.

"You've done it now!"

Wrenching the port oar from his horrified mate, he sprang aft, dropped it in the notch on the stern, headed the boat once more for the island, and began sculling with all his might.

It was a hopeless attempt. However strong he might be, no man with only one oar could make headway into the teeth of such a gale. For a time his desperate efforts held the dory in her place. Then little by little she began to go astern.

With sinking heart Percy watched Spurling's shoulders rack and twist as he threw his last ounce into his sculling. By degrees his motions became slower and more painful. Suddenly he pulled in the oar and dropped it clattering aboard.

"No use!" he groaned as he toppled backward and collapsed in the bottom of the dory.

BUOY OR BREAKER

Consternation seized Percy. Never before had he known Jim to acknowledge himself beaten. Their plight must be serious indeed.

The dory swung side to the sea and sank into the trough. A half-barrel of water slopped aboard. Percy bestirred himself. Setting the oar in the scull-hole, he brought the boat's head once more into the wind. He was not strong enough to drive her against it; but he could at least keep her pointed into the teeth of the gale and prevent her from swamping. He dropped to his knees, for it was too rough for him to keep his balance if he stood upright.

How far off was Tarpaulin? As he looked back a red glare sprang up northeast. Budge and Throppy had fired the driftwood beacon on Brimstone Point. Small good it would do Jim and himself to-night.

They could not reach the island with one oar, and it was now too dark for their friends on Tarpaulin to make out the drifting dory.

Percy began sculling frantically.

"Hi! Hi! Hulloo-oo!" he yelled. "Oh, Budge! Oh, Throppy! We're going to sea! Come out and get us!"

It was like shouting against a solid wall. His cries were whirled away by the gale. Presently he became silent, realizing that he was wasting his breath.

Rapidly the dory drifted seaward. The fire dimmed to a misty red glow. A smart shower burst, and great drops spattered over the dory.

Jim sat up. He turned his face toward the island, and Percy knew his eyes had caught the dying beacon. He said nothing; there was nothing to say. In a little while all was black, north, east, south, and west.

Then Jim spoke, and his voice was as calm and deliberate as if he were in the cabin on the island, instead of a mile to leeward, driving to sea before a norther.

"Well, Perce, we're in for it! I'm sorry I spoke so sharp when you broke that oar. It's an accident liable to happen to anybody. Let's take account of stock! We're in for a night and more on the water, and we want to do our best to keep on top of it, and not under it, until the gale blows itself out. The prospect isn't exactly rosy; still, it might be a blamed sight worse. We're in a good dory, and that's the best sea boat that floats."

"Aren't we likely to be picked up before morning?"

"Pretty slim chance. Everything small has scooted to harbor long before this. We haven't any light, and a vessel or steamer large enough to pay no attention to the storm would be as liable to run us down as to pick us up. So about the best we can hope for is to have everything give us a wide berth until daylight."

"Will the gale last as long as that?"

"Longer, I'm afraid. 'Most always we have one good, big norther in August that blows two or three days. I'm really the one to blame for getting us into this mess. I know the sea, and you don't. I ought to have had brains enough to stop on Seal Island. Well, it's no use crying over spilled milk. The only thing now is to try not to spill any more."

The rain was descending in torrents. Storm and night drew a narrow circle of gloom about the reeling boat.
