3. The principal kinds of wheel carriages made in this country, are the cart, the wagon, the gig, and the coach; and of each of these there are various sorts, differing in strength and mode of construction, to suit the particular purposes to which they are to be applied. The business of making these vehicles is divided into a number of branches; but, as the manufacture of the coach embraces a greater variety of operations than any other species of carriage, we have selected it as affording the best means of explaining the operations of the whole business. 4. In large establishments for making coaches and other vehicles of the best workmanship, the operators confine their attention to the execution of particular parts of the work; for example, one man makes the wheels, another the carriage and body, another fashions and applies the iron, another does the painting and polishing, and another the trimming. In smaller establishments, a greater proportion of the work is executed by one person. 5. The wheels of the coach, as well as those of every other vehicle in which they are used, are composed of a _hub_, and several _spokes_, and _felloes_. The hubs are commonly made of a kind of tough wood, called _gum_, which is reduced to the desired form in the lathe. The hole through the centre is made with a common auger, and enlarged with one tapering towards the point, and having through its whole length two cutting edges. The mortices for the spokes are made with a chisel driven with a mallet. 6. The spokes are made of white oak, and the felloes, of ash or hickory; and both are brought to the required form and smoothness with the saw, axe, drawing-knife, spoke-shave, chisel, and sand-paper. The constituent parts of the _carriage_, or _running gears_, are the _axles_, _perch_, and _spring_-_beds_, or _bolsters_, to which are added the _tongue_, or _pole_, and some other parts connected with it. 7. The joints in this part of the vehicle are made perfectly tight by the application of putty; whereas, in the body, glue is used for this purpose. The latter substance will not answer in the former case, since it cannot bear exposure to water. The wood generally employed for the carriage part, as well as for the frame of the body, is ash; and the several parts are sawn from planks of suitable thickness. In this part of the work, the operator is guided by patterns made of thin pine boards. The panels of the body are made of thin boards of poplar or bass-wood. The manner in which the several parts are dressed and put together is too obvious to need description.
