“Will you be kind enough to make that statement again?” asked the farm-dog, marching up to the bull-dog with his legs and tail very stiff, and a ridge of hair standing up straight on his back.

“As many times as you like,” replied the bull-dog, who had risen to his feet and had begun to walk in a wide circle around the farm-dog.

“Now look here,” said the Fire-Dog, “fighting isn’t allowed on our premises. If you want to fight, you must do it somewhere else. For my part, I don’t see any occasion for fighting. I’ve led such a busy life that I haven’t had any time to waste in that way, even if I had had the inclination for it.”

“This is a question of honor,” replied the farm-dog, “and there is only one way for dogs of spirit to settle it. Your friend there has insulted a friend of mine, and unless he takes back his words we will fight it out.”

“Take back my words?” growled Boxer. “What do you take me for?”

At this point a sudden and unexpected interruption came. The gong in the engine-house struck sharply. The three grays came rushing out of their stalls, and took their places in front of the engine. The harness was let down from the pulleys that held it, and fastened into place. The fire under the boiler was lighted, the driver was in his seat, the men on the engine, and with a clatter of hoofs out they dashed, Jack barking his maddest and bounding ahead in such excitement that all other thoughts were driven out of his head.

As for the two dogs who a moment before were ready to engage in mortal combat, they were so engrossed by the sudden interruption and the excitement, that for the time everything else was forgotten. To the farm-dog this was a novel sight, different from the way they did things in his quiet town, and not a particle of the scene escaped him. The bull-dog, with his natural pertinacity, was the first to return to the subject of their late quarrel; but the farm-dog’s owner, who had missed him, came back to hunt him up, and led him off, much to his disappointment and the bull-dog’s also.

“Wait till the next time!” he snarled as he was led away.

“You’ll find me on hand!” growled Boxer.

Boxer was not usually so ill-natured as he appeared in this episode, but it is true that he was of a peppery disposition, and not averse to picking a quarrel. He would have given anything to have been a fire-dog like Jack, and his disposition had become rather soured in consequence. He was a steadfast friend, on the whole, and would have given his life, if necessary, for his old friend Jack, whose good disposition made him beloved of all.
