33 per cent of sand capable of passing a sieve of 100 meshes per square inch (sand grains practically inch diameter and under), and that when freed from sand the interstitial spaces in the shingle were found to amount to 35.5 per cent. Hence it is evident that the sand originally fully filled the interstices of the shingle. This agrees with my own observations on the material immediately below the surface of the beach.

Six sections of the beach were published with my last paper, and on each was shown the level attained on 13 July, 1903, this being the date of highest foreshore subsequent to the dredging. On 12 July, 1907, I again surveyed these same section lines; this was the date on which the Committee of the Royal Commission on Coast Erosion visited Hallsands; and on 12 December, 1908, I once more surveyed the four northern sections. Time was not available to enable me to examine in detail the southern sections (5 and 6). On both these dates the beach had attained, and for some time previously maintained, positions of maximum elevation. Especially was the shingle at its greatest foreshore development on 12 December, 1908, when the low-water gradients toward the southern end of Hallsands were steeper than ever previously recorded.

The annexed sections give the comparison 1903-19071908. As a general result of these surveys I find that the shingle is rearranging its distribution to a slight extent, and the beach at Greenstraight is growing or has grown at the expense of the beach in front of the village. In 1903, as is now evident, the excavation made by the dredgers off Greenstraight had not yet robbed the beach lying southward to the full extent that was yet to be. If we say that Greenstraight has since recovered an additional 1 ft. 3 in. in height, and the extreme south of the village has consequently lost about 1 ft. 9 in. in height of beach, this would probably be a fair statement of fact. And one conclusion from my sections admits no question: between 13 July, 1903, and 12 December, 1908, no addition, even of the smallest, has been made to the total quantity of shingle between the Hare Stone and Tinsey Head. Five years and five months have passed without any indication of a recovery of the loss at Hallsands.

The sections above referred to are: Sec. 1, sixty feet south of bridge at Greenstraight; Sec. 2, in line of
