The materials used in the construction of arches in this country have been confined in the past to stone, bricks, iron, and steel ; and it is seldom that any other materials are used, unless it be for arches of very small spans, many engineers and architects, for reasons of extreme caution and safety, being indisposed to use concrete. But the use of Portland cement concrete is more satisfactory, not only as regards strength, but also as to first cost, an item which, at the present day, has in many instances to be seriously considered.

The subject of reinforced concrete has been dealt with from the technical point of view in many interesting papers which have been read before Institutions abroad and in England, but its commercial aspect, which is not without importance, appears to have escaped attention. Lucien Serraillier
