"And some are sulky..."

''And some are sulky, while some will plunge.
(So ho! Steady ! Stand still, you!)
Some you must gentle, and some you must lunge.
(There! There! Who wants to kill you?)
Some—there are losses in every trade—
Will break their hearts ere bitted and made,
Will fight like fiends as the rope cuts hard,
And die dumb-mad in the breaking-yard."
