Mr. T. N. W. Akroyd (Associate-Member) said Mr. Sutherland’s paper was mostimely. As the author had said in his introduction, whilst they had reached a state of relative complexity in the sampling and testing of clay soils, there had not, unfortunately, been the same progress during the last decade in the testing of cohesionless soils; but this paper, which was a thorough review of the subject, should stimulate interest and thought. But whilst they had been relatively inactive in the Western world, it appeared from recent literature that Russian activity might have provided some new ideas, which Mr. Akroyd would refer to later.
