The present remarkable development in the use of cement is the direct outcome of the careful and persistent observations and experiements of our engineers, mechanical, chemical and civil. There is not a structure of modern times built of natural stone or forms of burned clay that has not been duplicated in cement, and the latter is now meeting structural requirements hitherto impossible except by the use of iron, steel and timber and its advantages over the latter materials in the matter or cost, durability and freedom from injury by fire and water is only just coming to be known. Time has shown when cement is carefully selected and treated intelligently in the practical work of construction, enduring monuments are founded to the honor and credit not alone of the designer and builder, but, in justice, be it said, to the pioneers and courageous supporters of this important industry in our country, who have persevered in face of many discouraging and adverse conditions until the American product is recognized as standard the world over.
