Mr. W. T. HALCROW, who described the sea wall dealt with in the paper as a most interesting piece of work, said he had not known until recently that the work was carried out by Major Du-Plat-Taylor, although he was an old friend. One thing he had learned from the paper was the method evolved by the contractors to drive the sheet piling so that it would not creep and stand over at the top. He intended to remember that method, and if he ever came up against a similar problem he would try it. He expressed indebtedness to the author for the paper.

The PRESIDENT proposed a hearty vote of thanks to the authors for their papers, and to Dr. Ezer Griffiths for having presented, on behalf of his brother, the paper on pre-cooling facilities for the fruit export trade. He intimated that the Institution would convey its thanks by letter to Mr. Edgar Griffiths, of South Africa.

The PRESIDENT proposed a very hearty vote of thanks to Mr. Waters for having taken so much trouble to prepare, and for having travelled to London to present an extremely interesting exposition of a very important part of our civilised life. He personally had had no idea that so much ingenuity could be applied to the disposal of ordinairy sewage.
The scope of this paper is limited generally to the construction of bridges in steel, up to a limit of 250-ft. span. This range covers by far the majority of bridges which have been and will be undertaken in this country. T.C. Grisenthwaite
DURING the discussion of the paper on “The Effect of Existing Regulations on Pillar Design in Steel-framed Buildings,” the writer promised to give particulars of some tests which were made at the L.C.C. School of Building on the side-buckling of a steel beam. These particulars and results should have appeared in The Structural Engineer for April, but owing to illness, the writer was unable to prepare them. F.E. Drury
