" Black" Burton, a man evil-tempered and malicious, had been picking a quarrel with a tenderfoot at the bar, when Thornton stepped good-naturedly between.

当时，桑顿在酒吧好言相劝“黑”伯顿，——一个脾气暴躁、心狠手家伙，——不要老是欺负一个新来人。

No wonder he's like a boot, hard on the outside, giving shape to a pulp of tenderfoot.

难怪他就像一只靴子，外表坚硬，形成一团嫩脚。
