As originally designed, the dog-cart seems to have been built high, and, as its name implies, for the purpose of carrying dogs. Such a vehicle would seat four, a roomy, comfortable trap “with space under the seats, where a brace of pointers or other dogs could lie at ease.” As I have said in a preceding chapter, the sides of the cart “were made with Venetian slats to provide ventilation.” Such a cart, however, proved so agreeable that no long time elapsed before its original purpose was lost sight of, and it became one of the commonest of country carriages. Built on a small scale it was admirably suited for pony or cob. Numerous varieties exist. In the _tandem cart_, as generally constructed, the driver’s seat is high—the only cart, indeed, of the kind to maintain any height at all. In the _Ralli cart_ two seats are placed back to back, the foot-rest to the latter closing on the body when required. (Built somewhat on the lines of the ralli, by the way, is the Indian _tonga_, “a rather low, hooded vehicle ... furnished for draught by a pair of ponies on the curricle principle with pole and bar.”) The _Battlesden_, _Bedford_, and _Malvern carts_ are other varieties. More popular, perhaps, than any of these is the _governess cart_, which, while really in a class by itself, may be mentioned here. This is a low and particularly safe carriage, in which the seats are placed at the sides, as in the waggonette, and the door is at the back. An improvement on the governess cart, though not nearly so popular, is the _Princess car_, first designed in 1893. Here the back door is dispensed with, the entrance being in front. “The driving seat is arranged on a slide, whereby it can be moved forwards or backwards to adjust the balance; and it also enables the driver to sit facing the horse instead of sitting sideways as in the governess cart.”
