NOTES AND QUERIES
ground; they are not apparently built-up structures. Two possess shafts connecting the holes with the upper air and each has an entrance through which a man could crawl. Perhaps they are ancient charcoal ovens or equally ancient coral-lime kilns; but if so why so high up on the mountain side? If charcoal ovens they must be very old for it is many years since there was enough wood on this hillside to provide wood for kilns. In other parts of the Colony, similar holes have been found; there was one in a bank near Tai Tam reservoir and another was found when Aberdeen reservoir was constructed.'
The last reference is interesting. Only recently I was given several notebooks belonging to the late Walter Schofield (1888-1968), formerly of the Hong Kong Civil Service and a gifted amateur geologist and archaeologist. They contain the following reference to structures recorded at and near the Aberdeen reservoir in 1931:
"Aberdeen Reservoir, 14.3.31. Valley trending north from main valley, behind dam lies a flat open area with old paddy terrace walls. At north end of first patch of cultivation from mouth of valley is an oval structure of pounded earth, or chunam, mixed with small stones, 6' from E to W and 8' from N to S. Walls 3" thick and variable. No sign of roof or window. Floor uneven, of rough earth and stones. Two feet below it is a built-up field, triangular, each side about 8 yds long.
In main valley east of the dam, close to point where upper valley branches off, and on a southern slope, is a fairly well-preserved hut with part of the dome remaining. It is circular about 8' in diameter, and of chunam. It is on a steep slope, 15' above bottom of valley, where there are at present no signs of cultivation. On its inner side is a narrow square chimney-like groove in the wall, vertical, and with a stone wedged in the bottom almost like a grate front. The outer wall is broken by a gap not over one foot wide.
A third hut of similar type, preserving part of the dome, was seen in valley below Aberdeen New Road, north of the reservoir headquarters. This hut faces west and is on the eastern side of stream 8' or 10' above it. It was not closely examined."
These structures, particularly the second, seem to me very likely to have been charcoal kilns. These apart, there are two pits
