The ufual height of wheels extends to five feetfix inches, and are divided in four proportions,to contain from eight to fourteen fpokes, and only-half that number of fellies; and are reckonedeights, tens, twelves, or fourteens, which are thenumber of fpokes in a wheel, or fellies in a height, which regulates the number, is, for aneight-fpoked wheel, not to exceed three feet twoinches; for a ten, four feet fix inches; for a twelve^five feet four inches ; for a fourteen, five feet fixor eight inches. Thefe are the extreme heightsfor the different number of fpokes to each wheel,which fliould be rather more than lefs, in parti-cular to the fore wheel of a four-wheeled carriage, vhich.

There are three defcriptions of wheels, viz. theftraked, the hooped, and the patent rim : the dif-ference of either is only in the rim ; fo that inwheels there are four heights, and three forts,which make twelve different prices in the whole,fuppofing them all of one fize ; but as they aremade lighter for phaetons and chaifes than forcoaches and chariots, the prices vary accordingly.
