When they had crossed the wall, Mr. Ogden bent down and put the shoe on the ground, and called the dogs. The pointers understood him at once, and went rapidly on the scent, whilst the little party followed them as fast as they could. It led out upon the open moor. When they were nearly a mile from the house, Mr. Ogden told Sarah to go back and make a fire in little Jacob's room, and warm his bed. The two men then went forward in silence. It was bitterly cold, and the wind began to rise, whistling over the wild moor. It was now eleven o'clock; Mr. Ogden looked at his watch. Suddenly the dogs came to a standstill; they had reached the edge of a long sinuous bog with a surface of treacherous green, and little black pools of peat-water and mud. Mr. Ogden knew the bog perfectly, as he knew every spot on the whole moor that he was accustomed to shoot over, and he became terribly anxious. "We must mark this spot," he said; but neither he nor Jim carried a stick, and there was no wood for miles round. The only resource was to make a little cairn of stones. When this was finished, Mr. Ogden stood looking at the bog a few minutes, measuring its breadth with his eye. He concluded that it was impossible for a child to leap over it even at the narrowest place, and suggested that little Jacob must have skirted it. But in which direction--to the right hand or the left? The dogs gave no indication; they were off the scent. Mr. Ogden followed the edge of the bog to the right, and after walking half a mile, turned the extremity of it, and came again on the other side till he was opposite the cairn he had made. The dogs found no fresh scent; they were perfectly useless. "Make a noise," said Mr. Ogden to Jim; "make a noise with that horn." Jim blew a loud blast. There came no answering cry. The wind whistled over the heather, and a startled grouse whirred past on her rapid wings. An idea was forcing its way into Mr. Ogden's mind--a hateful, horrible, inadmissible idea--that the foul black pit before him might be the grave of his only son. How ascertain it? They had not the necessary implements; and what would be the use of digging in that flowing, and yielding, and unfathomable black mud? He could not endure the place, or the intolerable supposition that it suggested, and went wildly on, in perfect silence, with compressed lips and beating heart, stumbling over the rough land. Old Sarah warmed the little bed, and made a bright fire in Jacob's room. When Ogden came back, he went there at once, and found the old woman holding a small night-gown to the fire. His face told her enough. His dress was covered with snow. "Th' dogs is 'appen mistaken," she said; "little Jacob might be at Milend by this time."
