Some 4,000,000 barrels have been sold and used and its reputation for uniformity and reliability has been firmly established. To meet the continually increasing demand for Security Portland Cement it has been necessary to increase the capacity of the plant three times. The last additions, made in 1916, gave 833 per cent increase in output and brought the total capacity to over 1 ,000,000 barrels per year. Security is classed among the high silica Portland cements and for this reason is pre-eminently permanent, there being not the slightest tendency toward retrogression with age as is sometimes the case with high alumina cements. (See Bulletin No. 331 U. S. Geological Survey, page 27, and Taylor's Practical Cement Testing, page 103.) Security Cement is made under the strictest chemical supervision and every barrel is guaranteed to meet the Standard Specifications as adopted by the American Society for Testing Materials and approved by the American Society of Civil Engineers, and also by the U. S. Government Specifications. As a matter of fact. Security far exceeds these requirements. During the year ending June 30th, 1912, 35,925 barrels of Security Cement were used by the Commissioners of the District of Columbia and 3,592 samples were tested by the Engineer's Department. Every sample passed the specifi¬ cations, and not a single barrel was rejected—a record performance. Of other brands of cement used, nearly 2 per cent was rejected. Security has been tested and approved by many well-known testing labora¬ tories and has received the endorsement of many prominent architects and engineers, including the engineers of the U. S. Government, City of Baltimore, and of a large number of railroads. Security is regularly used by many of the largest and most critical users of cement in the country. Among others, the following: United States Government, in all departments (Treasury, War, Navy, total requirements of District of Columbia for several years, etc.) City of Baltimore, for all purposes (Sewerage, Water, Harbor, Electrical and City Engineer's Departments) State of Maryland Highways Department, etc. State of Pennsylvania Highways Department, etc. Baltimore & Ohio Railroad Company Cumberland Valley Railroad Company Norfolk & Western Railroad Company Western Maryland Railway Company Southern Railway Company Atlantic Coast Line Railroad Company Richmond, Fredericksburg & Potomac Railroad Company Charlottesville & Albemarle Railway Company Washington Southern Railway Company United Railways Company of Baltimore Security has been used in some of the most important work in the United States. For example, approximately: 40,000 barrels in harbor and dock improvements by City of Baltimore 425,000 barrels in sewerage system by City of Baltimore 18,000 barrels in City of Cumberland, Md., street paving, etc. 13,000 barrels in City of Waynesboro, Pa., street paving, etc. 23,000 barrels in City of York, Pa., street paving, etc. 5,000 barrels in City of Carlisle, Pa., street paving and general requirements 3.500 barrels in City of Staunton, Va., streets and general requirements 7,000 barrels in City of Easton, Md., for streets, bridges, etc. 6,000 barrels in City of Winchester, Va., for streets, bridges, etc. 30,000 barrels in Roland Park, Md., improvements 225,000 barrels in Government work in District of Columbia 50,000 barrels in Connellsville Extension of Western Maryland Railway 175,000 barrels in Maryland State Road work 30,000 barrels in Paw-Paw Cut-off of Baltimore & Ohio Railroad Company 50,000 barrels in Curtis Bay Piers of Baltimore & Ohio Railroad Company 20,000 barrels for double tracking requirements of Southern Ry. Co. 23,000 barrels for bridges, etc., to Norfolk & Western Ry. Co. 31.000 barrels for general uses of Cumberland Valley R. R. Co. 7.500 barrels in American Ice Company's Plant, Baltimore, Md. 148,000 barrels in work at plant of the Maryland Steel Company and Penn Mary Steel Co. (Branch of Bethlehem Steel Co.), Sparrows Point, Md. After all, the best guarantee of quality is that given by the multitude of structures built of Security Portland Cement, which stand as monuments to its permanency. Illustrations from actual photographs of a few' of these structures, selected as typical of a large number, are showm in the following pages. Mayor James H. Preston and Chief Engineer Cal¬ vin \\ .
