Equipped with baskets and hoes, the boys set to work, with jackets off and trousers rolled up. In two hours’ time, each one of them had filled a bushel basket to the brim, for the clams were thrown out by dozens at every turn of a hoe. “That’s enough bait for a start,” said Harvey, wiping his forehead. “We can buy more of the fishermen if we run short.” “My!” exclaimed Henry Burns, straightening himself up with an effort. “My back feels as though it had nails driven into it. I don’t wonder so many of these old fishermen stoop.” The day was very hot, and the boys went in for a swim. Then, when they had eaten, they stood out of the little harbour; but the wind had dropped almost entirely away, and, with the tide against them, they scarce made headway. “I’m afraid we won’t make Loon Island to-day,” said Tom. “Oh, perhaps so,” said Harvey. “See, there’s a line of breeze way down below.” A darkening of the water some miles distant showed that a southerly breeze was coming in. They got the first puffs of it presently, and trimmed their sails for a long beat down the bay. The _Viking_ was a good boat on the wind, the seas did not roll up to any great size, as the wind had come up so late in the day, and it was easy, pleasant sailing in the bright summer afternoon. Still, the breeze was too light for any good progress, and they had only reached Hawk Island, on which the lighthouse stood, and which was fifteen miles from Loon Island, by two o’clock. They were going down a long reach of the bay now that rolled some six miles wide, between North and South Haven on the one hand, to starboard, and a great island on the other. Back and forth they tacked all the afternoon, with the tide, turning to ebb just after three o’clock, to help them. By six o’clock they were two miles off the southeastern shore of South Haven, with great Loon Island, its high hills looming up against the sky, four miles across the bay. “Well, shall we try for it?” asked Harvey, eagerly scanning the sky. It looked tempting, for there had come one of those little, deceptive stirrings of the air that happen at times before sundown when the wind makes a last dying flurry before quieting for the night. The sun, just tipping the crests of the far-off western mountains across the bay, had turned the western sky into flame. Loon Island looked close aboard. So they kept on. Then by another hour the glow had faded from the sky and the waters blackened and the shadows began to die away on the hills of Loon Island, and all the landscape grew gray and indistinct. They were two miles above the harbour, when the bluffs that marked it blended into the dark mass of its surroundings and there was no guide left for them to follow. The wind had fallen almost to nothing. “We can’t miss it,” said Harvey, stoutly. “I’ve been in there once before.”
