Mr. L. SCOTT WHITE (Vice-president), in proposing a vote of thanks to the Author for his paper, said Mr. Ramsay Moon had presented the meeting with a great array of achievements accomplished during the war years.

After indicating his pleasure at being given the opportunity of having his work discussed at the Institution, the author pointed out that the range of size covered in his experiments so far was limited by the testing equipment available, the majority of columns tested being of 3.5 by 3.5 inches cross-section, with a core having 2.5 inches over main steel. A limited number of larger columns had been tested at the Building Research Station, some of which were geometrically similar, and some dissimilar, the results indicating that departure from similarity, and even departure from size, in some instances, were both liable to affect the laws governing the crushing load.

During the past two years, several papers have described different engineering aspects ofghe war effort in which the constructional steelwork industry has been concerned. The paper by Major W.J. Hodge, R.E., in January, 1946, on the Mulberry Harbour, and the paper by Lt.-Col. S. K-Stewart, R.E.in Nbvember, 1946, on Military Bridging, described two of the outstanding engineering successes of the war. Both these papers were of special interest to the welding enthusiast because they described work which was mainly welded, and could not have been built except by welding. For the design and operation of the equipment described in these two papers, the honour belongs to the Services and the Service Departments, but for the construction of the equipment much credit is due to the constructional steelwork industry.
