That was clearly the time for interference, but I regret to say that instead of interfering, the boys grouped themselves about with feelings of not unpleasant anticipation. I further regret to say that Ernest Whipple was one of the most interested.

Suddenly Mr. O'Brien, recovering from his surprise, returned to the attack with an impetuous rush which nearly bowled Mike over. But Mike was heavier than Mr. O'Brien and stood very solidly on his four outspread feet. He merely turned about and presented a terrifying front to his more active antagonist. Again Mr. O'Brien rushed, seeking a hold on Mike's big, muscular neck.

For a time Mr. O'Brien seemed to be having the best of it. He took the offensive and seemed to be on all sides of Mike at once. The bulldog's ear was bleeding and Harry urged him to retaliate.

Suddenly Mike raised his huge bulk and bore down the lighter dog beneath his weight. Then he began methodically seeking the vice-like hold that would have meant the last of Mr. O'Brien.

Just at that moment, however, a diversion occurred.

"Here, there, what are you doin'?" demanded a man's hoarse voice, and Sam Bumpus came striding into the thick of it. Without the slightest fear or hesitation, though such an act was decidedly not without danger, he darted in and seized the dogs by their collars, one in each hand, and displaying wonderful strength of arm he dragged them apart. If Mike had succeeded in getting his hold, if Sam had come up a minute later, he could not have done it. As it was, he held the snarling, struggling dogs at arm's length, shook them, and then ordered their masters to take them in charge and keep them apart.

Ernest had never seen Sam angry before; he was usually the embodiment of even-tempered good humor. But he was angry now. His jaws snapped and his eyes flashed, and he seemed to be itching to give somebody a good spanking. At last he spoke.

"I thought you boys was fond of dogs," he said. "I thought you made a great fuss about bein' kind to animals. You ought to be ashamed of yourselves, settin' two good dogs on to fight each other. Don't you know no better? Dogs are built to fight, and they ought to know how to when it's necessary, but any man or boy that starts 'em fightin' for sport is a coward."

Without another word he turned and vanished into the woods. The boys made no comments, either, and I am glad to say that most of them were about as ashamed of themselves as boys can be. By common consent the afternoon's expedition was abandoned and the company dispersed.
