ARMORED CONCRETE.

The professions of architect and engineer overlap so broadly in these days, that we may be excused for speaking of the progress of armoured concrete under the head of civil engineering. Indeed the development of this material of construction, or combination of materials, is proving to be as fully useful to the civil engineer as it is to the architect In the first place, it has served greatly to broaden the scope of masonry arch construction, the imbedded steel rods serving to give that tensional strength which uneven loading renders necessary in all arches and particularly those of long span. For subway it has taken the place of the steel column and concrete arch for walls and roofs, and when the steel is judiciously distiibuted it is doing good service, where formerly the massive steel column and the plate girder had come to be the standard construction on pier and viaduct work. The too frequent failures of armoured concrete aie always traceable to poor design or careless workmanship, never to any inherent fallacies in the principles of construction.
