We build in this country more of brick than of stone, because brick-earth is found almost everywhere, and stone fit for building is found only in particular districts. Bricks used to pay the state a duty of five shillings and ten pence a thousand; and yet at the kilns they were to be bought under forty shillings a thousand, which is less than a halfpenny apiece. The government wisely resolved, in 1850, to repeal the excise-duty on bricks. In 1845 the duty on glass was repealed. In 1847 the timber-duties were reduced; and in 1848 they were further reduced. The ever-present necessities of the people--the absolute want of house-accommodation for a population increasing so rapidly--rendered it a paramount duty of the government no longer to let tax interfere with the cheap building of houses. Every invention that adds to cheapness acts in the same direction; for although the direct taxes cease to press upon the various trades of building, the constant demand keeps bricks and timber at a price almost as high as before the removal or mitigation of the tax. But bricks, regarded as the production of a vast amount of labour, are intrinsically cheap. And why? Because they are made by what is truly machinery; as they were made three thousand years ago by the Egyptians.
The clay is ground in a horse-mill; the wooden mould, in which every brick is made singly, is a copying machine. One brick is exactly like another brick. Every brick is of the form of the mould in which it is made. Without the mould the workman could not make the brick of uniform dimensions; and without this uniformity the after labour of putting bricks together would be greatly increased. Without the mould the workman could not form the bricks quickly;--his own labour would be increased ten-fold. The simple machine of the mould not only gives employment to a great many brickmakers who would not be employed at all, but also to a great many bricklayers who would also want employment if the original cost of production were so enormously increased.

There is another material for building which was little used at the beginning of the century. The consumption of slate in London alone was, in 1851, from thirty thousand to forty thousand tons per annum. The quarries of Wales principally supply this immense quantity; but some slates are shipped from Lancashire and Westmorland, and from Scotland and Ireland. In the production of this one material, eight thousand quarriers are employed in Great Britain. Slates are not only used for roofing houses, but in slabs for cisterns and chimney-pieces. The great increase of the supply of water to houses by machinery led to a demand for a safer and cheaper material than lead for cisterns; and slate supplied the want.
