BEFORE Commencing this chapter, I here give Oliver W. Holmes's views on coach-building, as evidenced by his wonderful verses on the still more wonderful One-hoss shay." "THE ONE-HOSS SHAY." Have you heard of the wonderful one-hoss shay, It ran a hundred years to a day, And then of a sudden it—ah! but stay, I'll tell you what happened without delay: Frightening people out of their wits- Now, in building of chaises, I tell you what, THAT ONE-HOSS SHAY. Above or below, or within or without, With an "I dew vum," or an "I tell yeou"), It should be so built that it couldn' break daown. Is only jest T' make that place uz strong uz the rest." The cross-bars were ash, from the straightest trees; But lasts like iron for things like these; The hubs of logs from the "settler's ellum," Never an axe had seen their chips, And the wedges flew from between their lips, Found in the pit when the tanner died. "There!" said the deacon, "naow she'll dew." She was a wonder, and nothing less! Children and grandchildren, where were they? 359 First of November-the earthquake day- That there wasn't a chance for one to start. First of November, "fifty-five," Then something decidedly like a spill; All at once, and nothing first, O. W. H. Having spoken so much about coaching, I do not think it is out of place to make some remarks about coach-building; as there are some owners of carriages and gentlemen who are fond of driving, who, I should imagine, would feel interested in knowing something of their construction, which knowledge, I feel assured, will be of service to them in more ways than one. Before a carriage is put in hand careful drawings have to be made of it to scale, and although the designing of a carriage does not necessitate any very profound mathematical knowledge or calculations, yet carriage architects, when scale-draughting, require to do their work very carefully and skilfully. In addition to a reduced drawing, full-sized diagrams have frequently to be made in chalk on a blackboard, for the workmen to work to; these are placed up against the wall so that the various timbers used in the construction of the carriage may be compared with such drawings. As a carriage is composed of various parts, and as all these parts must exactly correspond with one another, it is absolutely necessary that a working draft of the full size be completed before a carriage can be made. In the first place, it depends upon the construction of a coach what difference will be required betwixt the heights of the fore and hind wheels, to bring the perch to a proper level; the depth from front to back of the body; and the height which it is to be hung from the ground is next required, in order to ascertain the proper length of the carriage, that is, what distance the fore and hind axle-trees are to be from one another; the particular manner in which the body is to be hung upon the carriage must also be fixed, in order to give the springs a proper degree of curvature. To obtain these particulars a draft is made of the entire machine, and from it the master-coachbuilder at once sees what effect will be produced. In making these drafts, the coachbuilder is limited, in a certain degree, by the fashion of the day; at the same time he has it in his power to display taste and judgment in the construction. His object should be to combine elegance with strength, and that one part of the vehicle shall be so in character with another, that the carriage shall not want anything that it ought to have, and not have anything that it could do without. He, also, has to be careful not to make any part heavier than absolutely necessary, and must be particular to make it easy of draught, by having the best finished axles set in such an exact manner, that the wheels may run perfectly free, following one another in the same track. There is no earthly reason why a gentleman of education and intelligence, who is fond of driving, and passes much of his time on the box, or the bench, as it used to be called, should not make a study of carriage-building, just in the same way as the owner of a yacht acquires a knowledge of yachtbuilding. I even knew an Admiral, who, when in command of the Channel Squadron, expressed a very strong wish to be thoroughly acquainted with iron ship-building and marine engineering; and it appears to me that when one passes so much of one's time making use of a particular thing, or having anything under one's entire charge, it is only natural and creditable that one should manifest some anxiety to become acquainted with its construction. In the event of any accident happening on the road or a carriage being out of repair, an owner would benefit considerably if he possessed some knowledge of coach-building; besides which, a coach-builder's account is, to any one not initiated into the mysteries of coach-building, as difficult to understand as a house-builder's account; in both cases it appears as |
