8. The wheels and the carriage, after having received one coat of paint, are sent to the blacksmith to be ironed. The hub is bound, at each end with hoops of iron, commonly plated with brass or silver, and the outside rim or felloes are bound with an iron _tire_, and fastened with strong nails or spikes. The tires are made red-hot before they are applied, that they may be made to fit in every part with accuracy. 9. Bands, bolts, or strips of iron, are applied to those parts of the wood-work which may be exposed to friction, or which require additional strength. The axles are also made of wrought iron, either by the blacksmith who executes the other iron work, or by persons who manufacture them by the quantity for sale. The same remark is applicable to the _thorough-boxes_, which are inserted into the hub to prevent injury by friction, and to cause the wheel to revolve with freedom and accuracy. 10. The painting, varnishing, and polishing, of the body of the coach, when done in the best manner, comprise a tedious process. It is first covered with a coat of paint; the grain of the wood is then filled up with putty, and the surface is again covered with paint. Five coats of _filling_, composed of ochre, japan varnish, and spirits of turpentine, are next successively applied. After the surface has been rubbed with a solid piece of pumice-stone, it is again painted, and rubbed with sand-paper. Several coats of paint are next laid on, and the work is finished by the application of a few coats of copal-varnish, and by the use of pumice-stone. The painting and varnishing of the wheels and carriage part, is far less expensive and tedious. 11. The nature of the trimmings, and the manner in which they are put together and applied, need not be described, since a few moments' inspection of a finished vehicle of this kind, will give any one a clear conception of the whole of this branch of the business. So far as trimming the inside, and the manufacture of cushions are concerned, the operations are similar to those of the upholsterer. 12. Wheel carriages may be classed among the primitive inventions, although the first authentic notice we have of their use, we find in the scripture history of Joseph, the son of Jacob, in which it is related, that this great and good man "was made to ride in the second chariot" of the king's, and that he sent wagons from Egypt to convey thither his father and family from the land of Canaan.
