Copper Refinery Tankhouse, Northern Canada: Design and Construction Features

A compliment and a complaint Mr. J. N. Barber has this to say about the journal and about certain observations in the Annual Report (April 1979): As an outsider who is nevertheless fortunate enough to see The Structural Engineer regularly, may I assure you that the present format and content of your journal is far superior to the fare served up in other places.

In dealing with the development of science and technology, historians are interested in identifying original idea5 or concepts and their subsequent diffusion and elaboration as well as in biographical information on famous scientists and engineers. From Samuel Smiles to L T. C. Rolt the biographical tradition has been a popular and powerful influence on the history of technology. This approach has tended to produce history on the heroic scale with little emphasis on the development and interchange of ideas or the continuity of technological change. On the other hand, an economic historian might well view certain aspects of the Industrial Revolution without more than a mention of those engineers responsible for particular technological developments. For example, one could view the history of the steam engine in terms of the number of units produced, their geographical distribution and resulting influence on the expansion of the factory system. This paper, however, is concerned with the ideas and leading engineers behind the development of the modern suspension bridge. E.L. Kemp

Mr. D. R. R. Dick (Past President): In 1940, when the Ministry of Works requisitioned Queen Anne's Mansions for the Admiralty, I was the structural engineer heading up the team resgonsible for maintenance in Central London. The maintenance surveyor asked me to go along there and give some guidance as to their structural soundness. I was therefore responsible for the figures that you quoted concerning floor loads and strengths-but I did not do them in kilonewtons!
