These must be regulated by the ground. A good driver avoids all quick and sharp turnings. In town, it is much better to drive on a little further, where another street may allow the ample room requisite in turning. If a carriage do not pass quite across a channel without turning, the perch must be twisted according to the descent, because one wheel falls as that at the opposite angle rises. By such a wrench, especially when going fast, the main or perch bolt is frequently broken, and every part strained. A loaded coach should never be turned short, even at a slow pace, for the coach is never safe when there is not an even bearing on the transom beds. If turned short, at a quick pace, the higher and looser part of a coach must go over, because all bodies put in motion by one power will proceed in a straight line, unless compelled to change their course by some force impressed. Hence a horse at full speed is with difficulty turned to right or left; and, if he turn suddenly, and of his own accord, he puts his rider’s horsemanship to the test. So with a coach, a sudden turn to one side the road allows the body to swag towards the other, and the centre of gravity is lost. In a turn, a coachman must point his leaders well, that is, take proper ground for them to make the turn, and let his wheelers follow them. Moreover, as wheel-horses are always in haste to make the turn, the driver must shoot them out on the opposite side, just as he has pointed his leaders. Thus, if the turn be to the right, he must catch up his near wheel rein, and hit his off wheel-horse; and _vice versâ_. This will keep the head of the pole (which he should have his eye upon) just between the leaders, and the wheelers will follow, as if they were running on a straight road. This will also secure him against danger, by clearing his coach of posts, gutters, &c. No man can make a neat turn with four horses, unless he shoot his wheelers, at the same time that he points his leaders. In turning, the wheelers must rather be kept up, and the leaders be tight in hand, to avoid the corner; for, if the wheelers flag, and the leaders draw, the carriage must be brought against it. THE RANKS IN TOWN. These must never be broken, either in driving through crowded streets, or in setting down at crowded places. As to admitting others into the rank, every driver should do as he would be done by. STOPS. It is a good plan to use horses to stop by notice, as it may prevent accidents. In pulling up, the driver must pull the reins equally, but rather those of the wheelers first. If this is attended with difficulty, take the wheelers’ reins in the right hand, and pull till they hang well on the breeching, or on the pole chains, thus increasing the leaders’ draught so much that they will easily be pulled up.
