He moved with a majesty only achieved by royalty and master craftsman. He was a jerkline skinner, the prince of the ranch, capable of driving ten, sixteen, even twenty mules with a single line to the leaders. He was capable of killing a fly on the wheeler’s butt with a bull whip without touching the mule. There was a gravity in his manner and a quiet so profound that all talk stopped when he spoke, His authority was so great that his word was taken on any subject, be it politics or love. This was Slim, the jerkline skinner.
– John Steinbeck
Of Mice and Men, Chapter 2. Slim, in his first real appearance to George and Lennie, is described as a man of authority, and having inherent dignity and majesty to him.
