He paused here, for often he had been told by Grandpa Horner that there were treacherous bogs in this part of the wood, which were so covered with mosses and ferns that the ground seemed solid enough to walk upon. But woe to the unlucky traveler who stepped unawares upon their surface; for instantly he found himself caught by the clinging moist clay, to sink farther and farther into the bog until, swallowed up in the mire, he would meet a horrible death beneath its slimy surface. His grandfather had told him never to go near these terrible bogs, and Jack, who was an obedient boy, had always kept away from this part of the wood. But as he paused, again that despairing cry came to his ears, very near to him now, it seemed: "Help!" Forgetful of all save a desire to assist this unknown sufferer, Jack sprang forward with an answering cry, and only halted when he found himself upon the edge of a vast bog. [Illustration: Jack Horner] "Where are you?" he then shouted. "Here!" answered a voice, and, looking down, Jack saw, a few feet away, the head and shoulders of a man. He had walked into the bog and sunk into its treacherous depths nearly to his waist, and, although he struggled bravely, his efforts only seemed to draw him farther down toward a frightful death. For a moment, filled with horror and dismay, Jack stood looking at the man. Then he remembered a story he had once heard of how a man had been saved from the bog. "Be quiet, sir!" he called to the unfortunate stranger; "save all your strength, and I may yet be able to rescue you." He then ran to a tall sapling that stood near and began chopping away with his axe. The keen blade speedily cut through the young but tough wood, and, then Jack dragged it to the edge of the bog, and, exerting all his strength, pushed it out until the sapling was within reach of the sinking man. "Grab it, sir!" he called out, "and hold on tightly. It will keep you from sinking farther into the mire, and when you have gained more strength you may be able to pull yourself out." "You are a brave boy," replied the stranger, "and I shall do as you tell me." It was a long and tedious struggle, and often Jack thought the stranger would despair and be unable to drag his body from the firm clutch of the bog; but little by little the man succeeded in drawing himself up by the sapling, and at last he was saved, and sank down exhausted upon the firm ground by Jack's side. The boy then ran for some water that stood in a slough near by, and with this he bathed the stranger's face and cooled his parched lips. Then he gave him the remains of his bread and cheese, and soon the gentleman became strong enough to walk with Jack's help to the cottage at the edge of the wood.
