AT the General Meeting of the Institution, held on Thursday, the 21st February, the following paper was read by DR. E. H. SALMON:-
I. That Euler’s limiting load merely implies passage from one type of stable equilibrium to another, and does not involve the failure of the column. (Quoted in "Popular Fallacies Explained and Corrected,” by A.S.E. Ackermann, BSc. Engineering), 3rd edition, p. 884, in the inverse form, from a review by L.N.G.F. in "Nature,” June 24, 1920.)
AMONGST the interesting developments expected in the Provence of Mozambique (Portuguese
East Africa) is the completion of it works to produce Portland Cement at Lourenço, Marques. At the present time a £9,O00,000 loan to the Provence is being negotiated and irrigation and other works will benefit. To find cement on the site as it were is therefore a matter of interest. The factory itself is interesting in that of its kind it is probably the last word in up-to-date manufacture, and a high class cement is expected. The construction stage has now terminated and production is likely to commence this month.

HOUSING is not a subject with which the Structural Engineer is generally concerned, but it is one which would benefit greatly by his attention. The principal object of this article is to present the case, from an engineering point of view, for the use of concrete for the present day building requirements, particularly in so far as the housing problem is concerned, and having regard to the shortage of bricks and skilled labour.
