I do not believe your habitual customers have their ideas more enlarged than one of your coach-horses.

They KNOWS the road, like the English postilion, and they know nothing besides.

They date, like the carriers at Gadshill, from the death of Robin Ostler; [See Act II.

Scene 1 of the First Part of Shakespeare's Henry IV.] the succession of guards forms a dynasty in their eyes; coachmen are their ministers of state; and an upset is to them a greater incident than a change of administration.
Their only point of interest on the road is to save the time, and see whether the coach keeps the hour.

This is surely a miserable degradation of human intellect.
