Station entitled "Tests of Bond between Concrete and Steel." These tests, which were niude by Professor D. A. Alliums, then Associate in Theoretical and Applied Mechanics at this University, and now Professor in Charge of the Structural Materials Research Laboratory, Lewis Institute, Chicago, have been a valuable contribution of science in furthering a number of the industries dependent upon Portland cement. In a class by themselves stand the group of bulletins, monographs or whatever you choose to call them, that has been issued by the Bureau of Standards in its series of Technologic Papers. These constitute ft contribution of inestimable value to those studies which have made many of the Portland cement industries realities, or have advanced them to a higher plane of efficiency than would have otherwise been possible. Among the Technologic Papers of the Bureau of Standards are these reporting: Results of Tests on the Strength of Reinforced Concrete Beams. Tests of Absorptive and Permeable Properties of Portland Cement Mortars and Concretes, together with Tests of Dampproofing and Waterproofing Compounds and Materials. The Effect of High-Pressure Steam on the Crushing Strength of Portland Cement Mortar and Concrete. Action of the Salts in Alkali Water and Sea Water on Concrete. Special Studies with a View to Preventing the Action of Electrolysis.

the Buropenn war, recovery of potash is likely to be a profitable side issue of cement manufacture The pioneer experiments of this kind were made by the Riverside Portland Cement Company in its plant at Riverside, Cal. Experiments have been carried on also by the Security Cement & Lime Company, near Hagcrstown, Md., and were made the subject of a quite comprehensive article in the Manufacturers' Record of May n t h , this year. While the recovery of potash from cement manufacture is in itself so new a development that its possible significance is not yet generally appreciated, it has, however, gone far enough to arouse many cement manufacturers to its possible importance. T refer to it only for the purpose of citing one more instance to prove that unthought-of possibilities in industry lie dormant awaiting the magic touch of the scientist. To-day we find that concrete has attained a point where its application is almost universal in the construction field because of its practically unlimited usefulness. Yet those who are familiar with the cement industries realize that there is still need for the scientist to advance further our knowledge of the properties and uses of this material. I believe that to-day we stand only on the threshold of concrete's possibilities. I have no doubt that those who are most active in the cement and allied industries to-day will, ten or fifteen years from now, look back

Variations and Results of Sieving with Standard Cement Sieves. The Standardization of Cement Sieves. Studies on the Hydration of Portland Cement. Investigation of the Durability of Cement Drain Tile in Alkali Soils. Strength and Other Properties of Concrete as Affected by Materials and Methods of Preparation, etc. Some of these studies are being extended at the present time with a view to reaching more nearly definite or final conclusions. Without the studies and tests that have been made of concrete and reinforced concrete with a view to determine the resistance of this material to fire and other destructive agencies. there would be no reinforced concrete buildings, no concrete roads, streets nor alleys, no concrete sewers, no cement drain tile—none of the many other structures and products of concrete which science has made possible Among the latest achievements of science in the Portland cement industry itself are experiments tending toward conservation of resources, in the possible recovery of potash as a byproduct of Portland cement manufacture. Experiments which have been made within the past year or two indicate that since our supply of potash from Germany has been cut off, because of

on our present practices with cement and concrete with pity for the little we really know of their wonderful possibilities.

THE MANUFACTURERS' DEPENDENCE ON CERAMIC RESEARCH

By W. D GATES

AH things* in all times, change. It is the law, the established order of things. Progression, speeding up, higher achievement, better wares and better service are strictly and rigidly demanded in each and every line of work. He who does not heed, who holds that what was good enough for his father is good enough for him, will be distanced, cast out, and left behind in the intense rush of the business life of to-day. It is absolutely the survival of the fittest. Prom the days of the Cave Man, in the matter of maintaining personal rights, the bare fist gave way to the war club, that to the flint arrow, to the flint musket, to the breech loader, the machine gun, and the mammoth cannon of to-day. Man grew from killing retail to killing wholesale; from killing closely by personal touch, to killing at twenty miles, men that he could
