Is it of the same breadth as the two hind ones?—It is broader, being four inches and a half.
Is the centre wheel a guiding wheel?—It is.
What portion of weight is upon that as compared with the others?—That must vary a little, but generally about one-third.
Is yours a coach?—No, it is a treble-bodied phæton.

Vehicles drawn by horses of equal weight, have usu-
