We did a certain amount of screening, where it seemed to be desirable, but although one does not profess to find everything, this did not actually result in our finding anything more than we had already secured in raking the soil over. There only remains to me the pleasant duty of expressing the indebtedness of the club to the Epping Forest Committee of the Corporation of London for permission to carry out the excavations. The work has been assisted by many volunteer observers, who have relieved me of my duties when other engagements have necessitated my absence. Among these I would specially name Mr. Percy Thompson, Mr. W. H. Ryde, Mr. G. C. Dunning, Mr. Leigh Hunt, and my wife. I was especially fortunate in securing the co-operation of Mr. G. C. Dunning, who stayed with me in September, 1927, and who devoted him- self daily to the work, and whose observations on the pottery are appended. REPORT ON POTTERY FRAGMENTS FROM AMBRESBURY BANKS, LOUGHTON CAMP, AND THE PILLOW MOUNDS AT HIGH BEACH, ESSEX. By Gerald C. Dunning, B.Sc. The excavations directed by Gen. Pitt-Rivers at Ambresbury Banks in 18814 and at Loughton Camp in 18825 brought to light some fragments of pottery from the bottom of the ramparts, on the old surface line of the ground. These fragments are of the greatest value—indeed, they are the only sure evidence—in indicating the date of construction of these camps. Two qualities of ware are represented, coarse and fine, and both are hand-made. The coarse pottery is rough to the touch, very hard, red or reddish-brown on the outer surface, with a fair amount of crushed flint in the paste ; all the fragments are too small to give any reliable idea of the shape of the vessels, but they were evidently large cooking-pots with thickened out- bent rims. The second class of pottery is a striking contrast to the coarse ware ; it is slightly soapy to the touch, about one-half 4 Trans. Essex Field Club, ii. (1882), 55. 5 Trans, Essex Field Club, iii.
