THE question of economy in reinforced concrete design may be discussed with regard to: 1. The engineering structure, 2. The architectural structure, and the two sets of conclusions may or may not coincide. John A Davenport

In reading a paper on "Reinforced Concrete Beams; and Posts," I realize fully that I should apologize to the members of the Institute and also to mining engineers, since I am neither a specialist in reinforced concrete nor a mining engineer. Stephen H. Dixon

THE following inquiry letter was issued to all members of the Concrete Institute at the end of June, 1909 :-

It is a great honour to me to be asked to read a paper before the Concrete Institute, particularly as this is, I believe, the first paper on the subject of steelwork construction which has been presented to it. S Bylander

Having been asked by your Secretary to contribute a paper on the above subject, I have much pleasure in placing before you the following notes. The limit of time at my disposal, however, makes it impossihle to give more than a brief outline; but fuller details may be found in my papers before the Royal Geographical Society, Research Department (see Geographical Journals, January, 1911, and March, 1912; before the British Association in Dundee last September (see Engineering, December 20th last); and a paper before the Society of Engineers of March 1, 1909. The last deals especially with the application of the principles of settlement to a works test for efficient mixing of concrete. To these I would refer any who wish to go farther into the matter than it is possible to do here to-night. Dr J S Owens

THE main object in writing this paper is to show the wide range of strengths as indicated by these tests. H C Johnson
