Read it through once

There were thirteen mules in the first heat; all sorts of mules, they were; all sorts of complexions, gaits, dispositions, aspects. Some were handsome creatures, some were not; some were sleek, some hadn't had their fur brushed lately; some were innocently gay and frisky; some were full of malice and all unrighteousness; guessing from looks, some of them thought the matter on hand was war, some thought it was a lark, the rest took it for a religious occasion. And each mule acted according to his convictions. The result was an absence of harmony well compensated by a conspicuous presence of variety--variety of a picturesque and entertaining sort.
