"Oh, it's all right! Bonded stuff, I'm tellin' you, brother! Go far's you like; more where this comes from. Can't fool me on liquor, you bet! Here, take a li'l sample, just to prove you'n me—"

He thrust the flask under Wren's nose. Irritated beyond endurance, Wren angrily struck it aside; there came a shivering crash of glass and an odor of raw whisky as the flask shivered on the brass guard-rail.

"Hey!" cried Slosson's indignant voice. "Now look what you've done! What's matter with you, eh?"

His hand clamped down suddenly on Wren's shoulder. Wren took the cigar from his mouth and shoved the glowing end into Slosson's hand.

"Get to hell out of here," he snarled.

A howl of agony burst from Slosson, then his fist drove into Wren's face and sent him sprawling. A long train of sparks flew out into the night from the cigar as it shivered; the train clattered over a crossing and the brakes screeched slightly, slowing down for a stop at a large town ahead.

To everything except each other, the two men on the observation platform were blinded.

Wren rose and hurled himself on Slosson, lashing out in wildcat fury. Every restraint was gone from him, swept away by a whirlwind of rage; he forgot everything except that detested face, and slammed his fists into it frantically.

It was well for Jimmy Wren that Slosson's muddled brain could not exert its usual keen cunning. Aghast before the unexpected passion of this attack, Slosson was slow to answer it in kind, until the sting and batter of Wren's blows hammering into his face roused him to response. Then, bearing forward with a storm of oaths, he beat back the more slender figure of Wren, his arms working like piston-rods. Both men were too beside themselves to hit vitally for the body; they struck only for the face, for punishment, insensate with mutual madness and battle-fever.

Wren had the worse of this slugging-match. Backed into a corner of the guard-rail, he received terrific punishment—until he seized an opening and got in a whip-crack blow to the mouth whose impact staggered Slosson. Enraged afresh, the latter flung himself bodily at Wren; the two men clinched, and went reeling back and forth across the narrow platform to the lurches of the train.
