The reservations that Professor Heyman expresses regarding the relationship of loads assumed in simple plastic design to real states of loading have some justification, particularly in view of the dubious nature of stochastic calculations in relation to extreme loading conditions. I find it, however, more difficult to follow his arguments in relation to deflexions and stability calculations. Professor M.R. Horne
For nearly thirty years, including seven years of war-time, I had no contact with the Institution headquarters except by post and through reading-or trying to read-the journal. In early days I knew only one name: Major Maitland, and I wondered but never understood what went on at 'headquarters'. How did 'they' decide whether or not I was to achieve my ambition to become a fully-fledged structural engineer? One realized that Major Maitland did not do all the work himself and that even given a President, elected yearly, the two of them must have a large body of assistance, both from the members themselves and from some sort of secretariat, to handle all the business-not fully understood by me of a major professional institution.

Mr. K. Kretsis (F) : I would like to ask a question with regard to tube combination by internal sub-division. The horizontal beam members of the external tube sides have a considerable stiffness, how is a comparable stiffness achieved in the horizontal beam members of the internal sub-divisions of the tubes so that they may have a substantial effect on the shear lag within the external cross-planes of the tubes?
