This happened four times, and the negro was red from the neck up. The fifth time his small round head dropped suddenly as Garvin launched another terrific blow. The fist and black poll met with a sharp crack. The negro was flung back on his haunches, but Garvin grasped his right hand and swore futilely. Garvin looked up at the bridge, holding forth his hand.

“Hey! Call ’im off; take a look at me meathook!” he shouted.

“You still have your feet,” said Brack.

The fight raged again. Garvin was on his back now, kicking furiously. At last a kick favored him; he knocked the negro down. But this was his undoing, for Black Sam in falling landed full length upon Garvin, and in an instant his short, thick fingers had closed upon the white man’s throat.

After awhile Brack gave a signal to Mr. Riordan, the chief engineer, who was standing below. Without any hurry or excitement, Riordan walked over and kicked the negro in the temple. The stunned black released his hold. With another kick Riordan lifted him clear off Garvin.

Brack turned toward Chanler.

“Well, are they worth keeping?”

“Oh, I s’pose so,” said Chanler, yawning as he rose. “Rather amusing. Suit yourself, cappy.”

“Come ’long, Gardy,” said Chanler, leading the way off the bridge. He chuckled a little pointing back toward the combatants. “Conceited scum, those. Fighting men. Bad men. Be interesting to see Brack make ’em behave.”

“Chanler,” I said, “do you mean to tell me that you found any pleasure watching that bestial fight?”
