Sledges of many shapes and fashions are in use during the winter in most countries where snow lies for any length of time upon the ground, as sledges glide more easily over its surface than do wheels. The Esquimaux and the Laplanders habitually use sledges, all more raised from the ground than the sledge that carries the casks of the brewers. The Swiss and other inhabitants of mountain districts use sledges to bring down hewn timber and faggots to the valleys; and a hundred years ago, when carts were not so numerous, it was common in England to load the new-made hay or sheaves of wheat on light high sledges for transport to the farm yard. In North America and Northern Europe, sledges of elegant shape are every year in use; and in Holland and Belgium, during some winters, not only do the gentry ride in sledges two or three months, but the meat, bread, and vegetables are run through the streets daily on hand sledges. Egypt is the chief of the countries of which we have any record of the arts and manufactures introduced by the progress of civilisation. Egypt had, at an early period, buildings composed of very large stones; in moving these the sledge and the roller were used; and it is natural that these should be combined to form a low truck or platform moving on rollers. Later on, wheels and axles were substituted for rollers; at first wheels were slices of the trunk of a tree, all solid pieces of wood, and firmly wedged to the axles. Thus the wheels and axle revolved together below the cart or truck, and were retained in their position by strong wooden pins like the thole-pins or rowlocks of a boat. The wheels and axle revolve together in tramway cars and in railway carriages. Carts are made in this way now in Portugal, Spain, and in South America. All the earlier carts seem to have been fitted only with a pole, and at least two animals seem always to have been yoked together to the vehicle. The objection to the wheels and axle in one piece is, that it is difficult to turn a vehicle thus fitted in a small space. Any one using a garden-roller round a corner may easily convince himself of this, for whilst the outer edge of the roller is going over the necessary sweep, the inner edge is sliding on and crushing the gravel walk; it should be moving independently. It was soon discovered in Egypt that it was better to have a fixed axle-tree, and allow the wheels to revolve independently of one another. A wheeled carriage appears to have been in very general use in Egypt at an early period, called a car or chariot: in the Bible it is usually translated “chariot.” There are paintings and sculptures upon the walls of the temples and tombs of Egypt which have lasted four thousand years, and from those we learn precisely the appearance of these chariots. They are of great interest to us, as they formed the chief means of conveying man for two thousand years before Christ, and were more or less the type of all other vehicles of the ancient world.
