A WONDERFUL DOG. — On Sabbath last two local preachers, belonging to the Primitive Methodists at South Shields, went to preach at Usworth, a colliery villabe some eight or nine miles off. They finished the labors of the day a little after 8 o'clock, and soon after set their faces homeward. The evening had passed, and night, robed in her starry stillness, had approached, giving the two preachers an opportunity of conversing on the sublimities of the stellar regions. They had not proceeded far in their interesting conversation when they were overtaken by a large Newfoundland dog, and some time elapsed before they took any particular notice of the animal. They pursued their way and still the dog followed, when they thought it necessary to drive him back, as he appeared to be a valuable animal, and his owner might come to some loss should he stray from home. Notwithstanding all the means employed, the dog followed, keeping the two preachers ahead at a respectful distance. They continued on their way, and came through some fields which lead to the main road. When coming through one of those fields, the dog passed them, making a whining noise as he came by, which, by their interpretation, sounded like a mark of disapprobation at their driving him back. Before they came to the hedge at the bottom of the field they heard the dog growling and barking, and upon advancing a few steps further, they were terror stricken at beholding three men in the hedge ready to pounce upon them. Two leaned back in the hedge, and the other slunk down, as the dog snarled and the two preachers passed by. The preachers went on quickly, leaving the dog in front of the rascals. After they had got about a mile further the dog came up to them again, and appeared pleased, as if he had found his master. They determined that he should follow, and that, when they separated, the one he followed should take him home, give him his supper and a night's lodging, and take him back the next day. They went on and down the railway, and as soon as they turned off the line to come onto a lane leading into the town, the dog turned round and took his departure home, leaving the two preachers in safety, and thankful for his sagacity and protection.
