The pebbles of Shropshire and Staffordshire, are of a hard substance, and only require a prudent application to be made good road materials. On the other hand, the Scottish roads, made of the very best materials, which are abundant and cheap in every part of that country, are the most loose, rough, and expensive roads in the United Kingdom, owing to the unskilful use of the material. The _formation_ of roads is defective in most parts of the country; in particular the roads round London, are made high in the middle, in the form of a roof, by which means a carriage goes upon a dangerous slope, unless kept on the very centre of the road. These roads are repaired by throwing a large quantity of unprepared gravel in the middle, and trusting that, by its never consolidating, it will in due time move towards the sides. When a road has been originally well made, it will be easily repaired. Such a road can never become rough, or loose; though it will gradually wear thin and weak, in proportion to the use to which it is exposed; the amendment will then be made, by the addition of a quantity of materials prepared as at first. As there will be no expense on such road, between the first making and each subsequent repair, except the necessary attention to the water-ways, and to accidental injuries, the funds will be no longer burdened with the unceasing expenditure, at present experienced, from continual efforts at repairing, without amendment of the roads. There cannot be a doubt, that all the roads in the kingdom may be made smooth and solid, in an equal degree, and to continue so at all seasons of the year. Their durability will of course depend on the strength of the materials of which they may be composed, but they will all be good while they last, and the only question that can arise respecting the kind of materials, is one of time and expence, but never of the immediate condition of the roads. The anxious provisions of the Legislature for _preservation_ of the roads have unfortunately taken precedence of measures for making roads fit to be travelled upon, or worth the care of being preserved. Will it be deemed presumptuous to propose, that some regulations may be adopted, for encouraging and promoting a better system of making roads, by eliciting the exertion of science, and by creating a set of officers of skill, and reputation, to superintend this most essential branch of domestic economy?
