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.
