[24] Pony riders often alternated "runs" with each other over their
respective divisions in the same manner as do railroad train crews at
the present time.

[25] "Wild Bill" Hickock was one of the most noted gun fighters that the
West ever produced. As marshal of Abilene, Kansas, and other wild
frontier towns he became a terror to bad men and compelled them to
respect law and order when under his jurisdiction. Probably no man has
ever equaled him in the use of the six shooter. Numerous magazine
articles describing his career can be found.

[28] Indians would sometimes gaze in open-mouthed wonder at the
on-rushing ponies. To some of them, the "pony outfit" was "bad medicine"
and not to be molested. There was a certain air of mystery about the
wonderful system and untiring energy with which the riders followed
their course. Unfortunately, a majority of the red men were not always
content to watch the Express in simple wonder. They were too frequently
bent upon committing deviltry to refrain from doing harm whenever they
had a chance.
