The crowds of visitors who during the Royal Show week in Melbourne inspected the elaborate exhibit by Mr David Mitchell of reinforced concrete or “raonier" manufactures, received (states the Leader) a vary vivid impression with regard to the precedence that this new combination is evidently destined to assume as the coming building material. Reinforced concrete is steel wire and concrete scientifically worked up together in due proportions, so that the peculiar properties of both these materials are secured to the utmost advantage- in combination. Steel is very strong, but it will bend. Concrete is very strong, but it will snap. All steel is very costly, and all concrete cheap. The science of the combination is in securing the highest possible breaking strain, and the lowest possible cost, together with a number of other small properties not possessed by either timber or bricks. Amongst these is its fireproof character. Buildings of all kinds, including houses, barns, silos, cither for ensilage or grain, culverts, mid an almost unlimited number of other purposes, are absolutely fireproof. It is also rot proof, not being liable to decay i n any form, and equally it is smut proof, being unaffected by either dampnoss or dryness. Another property of particular value in connection with agricultural uses is that it is proof against the attacks of mice, ants, grubs, or other pests, while as to its permancy, it is practically everlasting. Last, but not least, it puts in the claim of being cheaper than any other form of permanent construction.
