Betsy had had so many years' intimate acquaintance with her master that this encouragement to greater speed had long ago lost its real meaning to her. She had come to regard its gentle reiteration as a sort of pleasant lullaby, and jogged along more peacefully than ever.

They slowly rounded a curve in the road and came into view of their home, the little weather-beaten house facing the lake, with Aunt Kirsty's garden a glory of sweet-peas, the long rows of neat vegetable beds sloping down to the water, the straggling lane with the big oak at the gate. And there was Collie bounding down the lane, uttering yelping barks and twisting himself almost out of joint in his efforts to wag his tale hard enough to express his welcome. The Lad leaped down and ran to open the gate; Collie knocked him over in his ecstasy, and his father smiled indulgently as the two rolled over and over on the grass.

"Run away in to Aunt Kirsty and tell her we are home, Lad," he cried, as he drove past to the barn. The boy put the pin in the old gate and went frolicking along the lane, the dog circling about him. The lane ran straight past the house down to the water, hedged by an old rail fence and fringed with raspberry and alder bushes. From it a little gate led into Aunt Kirsty's garden, which surrounded the house. The boy paused with his hand on the latch of the gate, looking down at the water. And then he gave a loud, ecstatic "Oh!" that made Collie bark, and stood perfectly still. He could see Lake Algonquin spread out before him, stretching away to the north in lovely curves like a great river. Its gleaming floor was dotted with green, feathery islands. To the west, in a silver haze, lay the town; to the east, a low, wooded shore where the spire of the little Indian church pointed up like a shining finger out of the green. Great masses of clouds were piled high in the west, where the sunset was turning all the world into glory. But it was not the beauty of the scene that was holding the little boy spellbound. Down there, straight ahead of him, was a most marvellous thing, the fulfilment of his dreams. Across the radiant water, stretching from some fairy island in the heavens, far over to the opposite shore, hung a rainbow! And more wonderful still, right down there at its foot, just beyond Wanda Island, gleaming and beckoning, hung the pot of gold!

The Lad's heart gave a great leap. There it was, just as Peter Fiddle had described it! Why should he not go after it, right now, and bring it home to his father? He went tearing down the hill, Collie leaping at his side. Peter Fiddle had said that the reason more folks did not get the rainbow gold and be rich and happy ever after, was because they did not go after it right at once. For the pot of gold did not hang there very long, and might slip into the water with a big splash any minute, and be gone forever. So the Lad ran in frantic haste, and the dog bounded ahead and nearly rushed into the water, in his mistaken idea that he was to catch the gulls that came swooping so near and were off and away before he could snap. The old green boat belonging to his father was lying on its side half in the water; the Lad tugged at it madly without moving it an inch. He glanced about him and spied with delight Peter Fiddle's canoe lying upside down under the birches. Peter worked for his father, when not away fishing or playing the fiddle or spinning yarns; and when he went away by land his canoe was always at home, and sometimes the Lad had paddled out in it alone. He pulled and tugged at it manfully, and after great exertions that left him panting, he managed to launch it. Collie, just returned from a mad charge after the gulls, leaped in beside him. The boy seized the paddle and pushed off hurriedly. He seated himself on the thwart and looked out to get his direction. Yes, there it still hung, away out there at the end of the island, gleaming bigger and brighter than ever. The canoe was large, and the paddle clumsy, but he was filled with such a passion to get that gold that he made wonderful progress. He leaned far over the side, splashing the heavy paddle into, the water, until, what with his unsteady stroke, his dangerous position on the thwart, and Collie's mad attempts to catch the passing gulls, the wonder was that the rainbow expedition did not come to grief as soon as it was launched. But the Lad had been brought up on the water, and had already had many a lesson in canoeing from Peter Fiddle, and, after the first excitement, he realised his mistake. So he slid to his knees and ordered Collie to the bottom of the canoe in front of him. Then, gazing intently ahead, he paddled, in a zigzag course, out towards the wonderful golden haze.

Somehow it had a strange, elusive way of seeming to be in one place and then appearing in another. The canoeist grew hot, and panting with his efforts. The perspiration stood out on his round, rosy face, and the curls on his forehead became wet. He flung off his hat, and redoubled his efforts. He bent his head to his task, as his paddle bumped and splashed its way into the water. When he looked up again, he found, to his dismay, that Wanda Island lay right between him and his shining goal.

This little garden of spruce and cedar had heretofore marked the bounds of his excursions. His father had often allowed him to go out alone in the boat or Peter's canoe, but only when he was watching from the fields or the shore, and then he was permitted to go only up and down in the shelter of the island. But he did not hesitate to go farther, fearing the magic gold might vanish while he lingered. He revived his flagging energies by picturing his father's joy and wonder when he returned and came staggering up the path with the money. And then his father could wear his Sunday blacks every day in the week, and never work any more, but just ride to and from town all day long in a new buggy, a painted one like Doctor Blair's. And they would hire Peter Fiddle and young Peter every day in the year to hoe the fields, and they would give away everything they grew. And the people in Willow Lane would all be good and happy ever after. Oh, there would never be any trouble of any kind when he came home with that pot of gold!

He paddled manfully round the island, pushing through the reeds of the little bay and just skimming the rocks at the western extremity. But his arms ached so, that he had to pause a moment to rest. As he did so, he heard a loud whistle, and the steamer, Inverness, came round a far point and turned her long bowsprit towards the town, lying off to the left in a shining mist. The boy grabbed his paddle again and redoubled his efforts. Peter had gone down to Barbay that morning on the Inverness, and was in all likelihood on board, and although the young adventurer intended to reward Peter liberally for the use of his canoe, he felt it would be safer for him to have it on shore before its owner returned. He took one tremendous splashing stroke, and, as he did so, he felt a strange, sharp pain in his right arm. It made him cry out so loud that Collie turned quickly to him with a whine of grieved sympathy. The boy dropped the paddle across his knee and caught his arm. Gradually the pain left and he took up the paddle again. But somehow the glory of the expedition seemed to have vanished. He wanted Aunt Kirsty when that pain came into his arm, more than he wanted all the gold of all the rainbows he had ever seen. He bent to his paddle with much less vim, and slowly and painfully round the island he came, and out into the open lake. And then,—where, oh, where, was the pot of gold? And where was the rainbow? He seemed to have come out with one stroke of his paddle from a world that was all colour and light to one that was cold, grey and dreary. He looked about him amazed. All the beauty of the lake had faded into mist. The rainbow was gone! A chill, damp breeze fanned his hot face, coming down from the north, where the clouds had grown black. The little mariner sat on his heels in the bottom of his canoe and looked about him in dismay. Surely the pot of gold had not gone. Perhaps it was hidden away behind those dark clouds and would come gleaming out again right in front of him. But though he sat and waited, the world only grew greyer and darker. Collie stood up again and barked defiance at a heron that sailed away overhead, but his little master sharply bade him lie down. The pain in his arm gave another twinge, and slowly and sadly he took up his paddle and turned his canoe homeward.

As he did so he felt a light breeze lift him. It came from the north, where those dark clouds had swallowed up his rainbow. A strange, weird thing was happening up there in those clouds, and the boy paused to watch. Down the shimmering floor of the lake, sweeping slowly towards him, came a great army. Stealthy, hurrying shapes, with bent, grey-cowled heads, and trailing garments, rank on rank they stole forward, mystery and fear in their every movement. Many a time, on an autumn evening, the boy had watched the fog start away up the lake and come stealing down, until the islands and the town and the forest were covered as with a blanket. But he had never seen anything so awesome as this. The strange shapes into which the light gusts of wind had driven the mist made them look like an army of ghosts driven out of the haunts of night. They were bringing night in their train, too. For as they swept silently onward, everything in earth and lake and sky was blotted out. One by one the islands vanished; the far-off eastern shore was wiped away as if by some magic hand. The tower of the little Indian church stood out for a moment above the flood and then sank engulfed; and the next moment the great host had swept over the little sailor and he was walled in and cut off from land and water, alone in a cloudy sea with neither shore nor sky nor surface. The boy turned swiftly towards his home, and when he saw that it, too, was gone, he uttered a cry of terror. "Daddy, oh, Daddy!" he wailed. Collie came close and licked his face and whined, then looked about him and growled disapprovingly at the weird thing that surrounded them. The boy put his arms tight around the dog's neck and hugged him. "Oh, Collie!" he cried, "we're lost, and I don't know where home is and where Daddy is." It was not the loss of gold that troubled him now. He stared about him in the greyness, striving to make out some object. The fog was so thick that he could see only the length of the canoe, but a big, darker mass of shadow in a world of shadows, told him where Wanda Island lay, and grasping his paddle, he started in what he believed to be the direction of home. He paddled until he was out of breath, rested a moment, then went at it again with all his might. The pain in his arm returned, but he dared not stop. And as he worked madly in his efforts to reach home, the gentle wind was slowly but surely carrying him out to the open lake.

Every few minutes the thought of his father would overcome him and he would drop his paddle and, sinking down beside Collie, would sob aloud. Then he would rise again bravely and go at his task, but each time with feebler efforts. The pain in his arm, which kept returning at intervals, was sometimes so bad he had to stop and nurse it. He was wet to the skin now, and Collie's hair was dripping. Whenever he rested, he spent the interval calling loudly for his father, while Collie helped him by barking, but though he listened till his ears were strained, only the soft lap, lap, of the waves against the canoe answered. As night came on the thick pall grew heavier and blacker, and at last he could not see even the length of the canoe.

The sore arm became almost helpless at last, and he could paddle only a few strokes at long intervals. He slipped down beside Collie, hugging him close, and sobbed out on his sympathetic head his sorrow for the rash venture. He even confessed that he wished he had left his friend at home. "Aunt Kirsty and Daddy will be that lonesome, Collie," he wailed, "without either of us. But I couldn't do without you at all, Collie!" he added. And Collie licked his face again, and whined his appreciation of the compliment. They seemed to drift on and on for hours and hours. The boy's imagination, fed by the wild tales from Peter Fiddle—tales of shipwrecks at sea, and dead men's bones cast upon haunted islands—, became a prey to every terror. There were ghosts and goblins out here, and water fairies, that might spirit you away to a land whence there was no returning; and there were those other creatures so terrible that Peter had not dared even to describe them, called "Bawkins." He shivered at the thought of them, and clung to the dog, too frightened to cry out. He had been trying to pray in broken snatches, but now, in his extremity of fear, he felt he must put up a petition of more force. He scrambled to his knees and tried to get Collie to join him by bowing his head. But Collie seemed of an altogether irreverent nature, and only licked his little master's face all the more. So the Lad gave it up, and, putting his hands together behind the dog's head, whispered: "Oh, dear Lord, we're lost, me and Collie. Please send Father and Peter Fiddle with the boat to find us. Please don't let us get drownded or don't let the Bawkins get us. And please don't mind Collie not prayin' right, 'cause he's only a dog, but he's lost, too; and please bring us safe home. And oh, Dear Jesus, I'm sorry I came out alone to hunt for the pot o' gold, but I didn't know it was so far, and please won't you make Daddy and Peter Fiddle hurry, 'cause I'm so cold and so hungry and my arm's awful sore and I can't paddle no more. And please, if Peter Fiddle ain't home yet and has gone off and got drunk, won't you please send young Peter with Daddy. And please send them in a hurry." He paused, but felt he must end in a more becoming way. It was his first extemporaneous prayer of any length, and he scarcely knew how to close. Then he remembered how Dr. Leslie, in the church where he went every Sabbath with his father, was wont to bring his morning petition to a close, so he added, "Only please, please, don't let Peter Fiddle get drunk to-night—world wifout end. Amen."
