It may in this place be observed, that no stage-coach should be permitted to travel the road with wheels secured only by the common linchpin. It is in consequence of this that innumerable accidents have happened to coaches from wheels coming off; and in these improving and fast times, such chances should not be allowed to exist. It may not be uninteresting to the uninitiated to learn from the same clever and experienced writer how a coach is worked. Suppose a number of persons to enter into a contract to horse a coach eighty miles, each proprietor having twenty miles; in which case he is said to cover both sides of the ground, or to and fro. At the expiration of twenty-eight days a settlement takes place, and if the gross earnings of the coach be £10 per mile, there will be £800 to divide between the four proprietors, after the following charges have been deducted, viz., tolls, duty to government, mileage (or hire of the coach to the coach-makers), two coachmen’s wages, porters’ wages, rent or charge of booking-offices at each end, and washing the coaches. These charges may amount to £150, which leaves £650 to keep eighty horses, and to pay the horse-keepers for a period of twenty-eight days, or nearly £160 to each proprietor for the expenses of his twenty horses, being £2 per week per horse. Thus it appears that a fast coach properly appointed cannot pay, unless its gross receipts amount to £10 per double mile; and that even then the proprietor’s profits depend on the luck he has with his stock. COACH-HORSES. A great change has lately taken place as to the English coach-horse; and this is the foundation of many other accompanying changes. Fifty years ago, the putting a thorough-bred horse into harness would have been deemed preposterous. In the carriages of gentlemen, the long-tailed black, or Cleveland bay--each one remove from the cart-horse--was the prevailing sort; and six miles an hour was the extent of the pace. Now, however, this clumsy-barrelled, cloddy-shouldered, round-legged animal, something between a coach and a dray horse, as fat as an ox, and, with all his prancing at first starting, not capable of more than six miles an hour, and rendered useless by a day’s hard work, is no more seen; and, instead of him, we find a horse as tall, deep-chested, rising in the withers, slanting in the shoulders, flat in the legs, with more strength, and with treble the speed.
