THE American Concrete Institute has recently published an analysis of the number of rigid frame bridges built during the last decade, and these figures show in a striking fashion the remarkable and steady increase in this type of construction in the United States. In 1926 the number of portal frame bridges built was seven, in 1931 it had risen to 39 per annum, and the number constructed in 1936 was 81. About 70 per cent. of the portal frame bridges since 1922 have been of a single span.

The Effect of Concrete Encasement on the Behaviour of Beam and Stanchion Connections. Discussion on

The CHAIRMAN (Mr. M. B. Buxton, M.C., M.A., A.M.Inst.C.E., Vice-president) said that Professor Batho needed no introduction to members of the Institution, for his work at Birmingham University was well known, and his name appeared in many scientific reports. This paper on the effect of concrete encasement was of the greatest interest to members.

Masonry Construction. Discussion on Mr. S. B. Hamilton's Paper.

Mr. W. H. WOODCOCK, A.I.Struct.E., in proposing a vote of thanks to Mr. Hamilton for his excellent paper and for the way in which he had presented it, said that he had been specially interested in the account of the tests which Mr. Hamilton had described at the end of the paper. He had himself watched the bricks crack under the tests, and he remembered that on one occasion the stress was so great that the steel joist buckled up and left the bricks standing. One of the things that had impressed him in connection with the lecture was the enormous amount of trouble Mr. Hamilton must have taken in getting the slides and presenting them in such an able way.
