The day was done, and the merrymakers had nearly all departed.  But as Martin and Lizzie emerged from the trees they found the gang waiting for them.  Martin knew immediately the meaning of it.  Trouble was brewing.  The gang was his body-guard.  They passed out through the gates of the park with, straggling in the rear, a second gang, the friends that Lizzie’s young man had collected to avenge the loss of his lady.  Several constables and special police officers, anticipating trouble, trailed along to prevent it, and herded the two gangs separately aboard the train for San Francisco.  Martin told Jimmy that he would get off at Sixteenth Street Station and catch the electric car into Oakland.  Lizzie was very quiet and without interest in what was impending.  The train pulled in to Sixteenth Street Station, and the waiting electric car could be seen, the conductor of which was impatiently clanging the gong.

“There she is,” Jimmy counselled.  “Make a run for it, an’ we’ll hold ’em back.  Now you go!  Hit her up!”

The hostile gang was temporarily disconcerted by the manoeuvre, then it dashed from the train in pursuit.  The staid and sober Oakland folk who sat upon the car scarcely noted the young fellow and the girl who ran for it and found a seat in front on the outside.  They did not connect the couple with Jimmy, who sprang on the steps, crying to the motorman:-

“Slam on the juice, old man, and beat it outa here!”

The next moment Jimmy whirled about, and the passengers saw him land his fist on the face of a running man who was trying to board the car.  But fists were landing on faces the whole length of the car.  Thus, Jimmy and his gang, strung out on the long, lower steps, met the attacking gang.  The car started with a great clanging of its gong, and, as Jimmy’s gang drove off the last assailants, they, too, jumped off to finish the job.  The car dashed on, leaving the flurry of combat far behind, and its dumfounded passengers never dreamed that the quiet young man and the pretty working-girl sitting in the corner on the outside seat had been the cause of the row.

Martin had enjoyed the fight, with a recrudescence of the old fighting thrills.  But they quickly died away, and he was oppressed by a great sadness.  He felt very old—­centuries older than those careless, care-free young companions of his others days.  He had travelled far, too far to go back.  Their mode of life, which had once been his, was now distasteful to him.  He was disappointed in it all.  He had developed into an alien.  As the steam beer had tasted raw, so their companionship seemed raw to him.  He was too far removed.  Too many thousands of opened books yawned between them and him.  He had exiled himself.  He had travelled in the vast realm of intellect until he could no longer return home.  On the other hand, he was human, and his gregarious need for companionship remained unsatisfied.  He had found no new home.  As the gang could not understand him, as his own family could not understand him, as the bourgeoisie could not understand him, so this girl beside him, whom he honored high, could not understand him nor the honor he paid her.  His sadness was not untouched with bitterness as he thought it over.
