time sand diggers had cut through the sandbank, the cliff was divided into sections by their activities, and objects could be and were photographed in groups. A sketch of the section was made showing the relative position of each object, its number in the group, and its depth; each piece was extracted; its number, depth, reference letter of the section, and date of the photo were recorded on the wrapping paper, and later in Chinese ink on each object. The sketch-map at Fig. 1 shows the relative positions of the sections, lettered from A to Q.
OBJECTS FOUND:
A. IMPLEMENTS AND OTHER OBJECTS OF STONE (See Plate 3) 1. Found at known levels:
Triangular hand hoe very roughly flaked to shape, and worn on one point. Made from a water-worn pebble of quartz-felsite, imported to the island. From sector K, depth 132 cm.
Part of ring of dark gray dyke rock, roughed out but unfinished: either broken in the making, or put with a corpse as a cheap substitute for a well-made ornament: too small for a bracelet except for a small child. From west cliff, depth 107 cm.
Part of quartzite ring, polished, levelled at edge of perforation, and with vertical outer edge, 7 mm. thick. From sector C, 89 cm.
2. Found loose: sectors known:
From sector I; grooved piece of hard reddish sandstone, evidently for smoothing such objects as arrow shafts. All grooves are 7 mm. in diameter, and are found on all surfaces of the stone. It could have been obtained from the coast of Lantau near Tai O.
Broken portion of large polished and shouldered adze: 4 cm. of the tang and 3 cm. of the body on one side remain. The shoulder has been hollowed out in part by pecking. The material is a fine-grained acid rock, probably from one of the many dykes of that type in the Lantau hills; it appears to have abundant small muscovite crystals.
From sector K: part of a roughed-out 'blank' for making what may have been intended for a shouldered adze. The edges appear to have been hammered to produce a secondary flaking, and possibly an unlucky blow split the stone and the worker threw it away.
From hillside above sector L: an implement originally formed as a polished adze, with curved edge making an angle with the rounded sides, and later blunted by wear and discarded. Later
