"Comrades," he said in a whisper, "I have heard rumors that there is a clue to the treasure hidden in the sign-tree." It was enough. With one accord the Band sprang upon that defenceless tree. Some searched among its gnarled roots. Others examined the lower branches. It was Henny-Penny, however, who boosted by Alice-Palace, fumbled back of the threatening old sign and drew out a crumpled slip of grimy paper. On it had been laboriously inscribed in some red fluid, presumably blood, a skull and cross-bones. Underneath, in a very bad hand, was written: "By the roots of the nearest black-walnut tree. Captain Kidd." There was a moment's check. It was Honey who recognized the tree by its crooked clutching twigs, and found at its roots a crumpled piece of paper which said: "Go to the nearest tulip tree. Blackbeard the Pirate." It was Trottie who remembered that a tulip tree has square leaves, and it was he who found the message which read: "I am buried under a stone which stands between a spice-bush and a white-ash tree." They all knew the spice-bush, with its brittle twigs and pungent bark which was made to be nibbled, and under the stone they found a note which said: "Look in the crotch of a dogwood tree. If you will listen you will hear its bark"; which made the Band laugh like anything. The last message of all read: "I am swinging in a vireo's nest on the branch of a sour-gum tree." That was a puzzle which held the Band hunting like beagles in check for a long time. Corporal Alice-Palace at last spied the bleached little basket-nest at the end of a low limb. Inside was a bit of paper which, when unfolded, seemed to be entirely blank. So were the face of the Band as they looked. It was the Captain again who saved the day. "I have heard," he whispered, "that sometimes pirates write in lemon-juice, which makes an invisible ink that needs heat to bring it out. Like the Gold-Bug, you know." It was enough. In less than sixty seconds, sun time, the Band had built a tiny fire after the most approved Indian method, and as soon as it began to crackle, the paper was held as close to the blaze as possible. The Captain had the right idea. As the paper bent under the heat, on its white surface brown tracings appeared, which slowly formed letters and then words, until they could all read: "I am in the hidey-hole of the chimney of the Haunted House. The Treasure."
