Then once again he would have passed Master Barney.

The would-be detective was not brave save where he believed he had a decided advantage, and the fact that Seth seemed eager to avoid an encounter gave him great confidence in his own abilities.

He stepped up menacingly, brandishing his fists directly under Seth's nose, and Dan cried sharply to his partner:

"Why don't you knock his head off?"

"He don't dare to so much as raise his hands, except he's up 'round Ninety-four's house, where he thinks some of the firemen will back him!" Sam cried derisively as he redoubled his efforts to provoke the amateur.

Seth's cheeks were flaming red, and he clenched his fists until the knuckles were white, in the effort to restrain himself.

If he had been alone there is every probability he might have forgotten his determination to avoid such encounters, for the would-be detective was doing all he could to provoke a quarrel; but Dan Roberts, understanding full well why his partner remained inactive when the temptation to strike at least one blow was very great, took it upon himself to put an end to the scene.

Sam was standing directly in front of Seth, brandishing his fists, and indulging in such epithets as "coward" and "sneak," when Dan sprang forward suddenly, striking the bully a blow under the ear that sent him headlong into the gutter.

Then, after looking quickly around to make certain there were no policemen within ear-shot, he leaped upon the discomfited detective, seizing him by the coat-collar in such a manner that it was impossible for Sam to raise his head.

"You're awful keen on havin' a row, an' I'm goin' to give you the chance! You knew Seth wouldn't put up his hands, because he don't count on havin' any black marks against him when he goes into the Department; but I ain't figgerin' on anythin' of that kind, an' can stand a little bit of a bad name for the sake of servin' you out."
