A carefully executed full size drawing of these stakes was made by me directly they were found, and the accompanying illustrations have been photo- graphically reproduced from the original sketches. On dry- ing, the stakes became greatly shrivelled, twisted, and split, and the pointed ends hardly recognizable. However, they were sent in their shrunken and cracked condition with various other things to the British Museum, Bloomsbury.

It is taken looking north, from Stoke Newington Com- mon, Middlesex, on the west; to the south of Walnut Tree House,andsoto Mover's Lane, Leyton, Essex, on the east.
