Mart was a peaceable soul, and in the approaching crisis Luck knew he would climb hurriedly upon the fence of neutrality and stay there; and Luck could fight or climb a tree as he chose.

He measured him mentally from pigskin puttees to rakish, stiff brimmed Stetson with careful dimples in the crown and a leather hatband stamped with horses' heads and his initials.

In a picture, Luck would have cast Bently Brown, costume and all, for a comedy mining engineer or something of that sort.
