That the present methods of working the quarries admit of vast improvement is universally acknowledged. The recent invention of Mr Munro, which so far warrants the belief that the cost of quarrying will now be reduced one-half, is one step—only one—in the right direction. In carrying on operations on a more extensive scale, it is impossible, however, to estimate the extent to which steam power and other improved appliances may economise labor. Your Committee have, however, had abundant evidence, that at every stage, from the quarries to its final destination, the larger operations of a Company, with improved methods, would materially diminish the cost of the material.
