There were shade trees all along that street, that you could climb if you wanted to, or that you could lie down under when you had run yourself out of breath, or play mumble-the-peg. My boy distinctly remembered that under one of these trees his elder brother first broached to him that awful scheme of reform about fibbing, and applied to their own lives the moral of "The Trippings of Tom Pepper;" he remembered how a conviction of the righteousness of the scheme sank into his soul, and he could not withhold his consent. Under the same tree, and very likely at the same time, a solemn conclave of boys, all the boys there were, discussed the feasibility of tying a tin can to a dog's tail, and seeing how he would act. They had all heard of the thing, but none of them had seen it; and it was not so much a question of whether you ought to do a thing that on the very face of it would be so much fun, and if it did not amuse the dog as highly as anybody, could certainly do him no harm, as it was a question of whose dog you should get to take the dog's part in the sport. It was held that an old dog would probably not keep still long enough for you to tie the can on; he would have his suspicions; or else he would not run when the can was tied on, but very likely just go and lie down somewhere. The lot finally fell to a young yellow dog belonging to one of the boys, and the owner at once ran home to get him, and easily lured him back to the other boys with flatteries and caresses. The flatteries and caresses were not needed, for a dog is always glad to go with boys, upon any pretext, and so far from thinking that he does them a favor, he feels himself greatly honored. But I dare say the boy had a guilty fear that if his dog had known why he was invited to be of that party of boys, he might have pleaded a previous engagement. As it was, he came joyfully, and allowed the can to be tied to his tail without misgiving. If there had been any question with the boys as to whether he would enter fully into the spirit of the affair, it must have been instantly dissipated by the dog's behavior when he felt the loop tighten on his tail, and looked round to see what the matter was. The boys hardly had a chance to cheer him before he flashed out of sight round the corner, and they hardly had time to think before he flashed into sight again from the other direction. He whizzed along the ground, and the can hurtled in the air, but there was no other sound, and the cheers died away on the boys' lips. The boy who owned the dog began to cry, and the other fellows began to blame him for not stopping the dog. But he might as well have tried to stop a streak of lightning; the only thing you could do was to keep out of the dog's way. As an experiment it was successful beyond the wildest dreams of its projectors, though it would have been a sort of relief if the dog had taken some other road, for variety, or had even reversed his course. But he kept on as he began, and by a common impulse the boys made up their minds to abandon the whole affair to him. They all ran home and hid, or else walked about and tried to ignore it. But at this point the grown-up people began to be interested; the mothers came to their doors to see what was the matter. Yet even the mothers were powerless in a case like that, and the enthusiast had to be left to his fate. He was found under a barn at last, breathless, almost lifeless, and he tried to bite the man who untied the can from his tail. Eventually he got well again, and lived to be a solemn warning to the boys; he was touchingly distrustful of their advances for a time, but he finally forgot and forgave everything. They did not forget, and they never tried tying a tin can to a dog's tail again, among all the things they tried and kept trying. Once was enough; and they never even liked to talk of it, the sight was so awful. They were really fond of the dog, and if they could have thought he would take the matter so seriously, they would not have tried to have that kind of fun with him. It cured them of ever wanting to have that kind of fun with any dog.
