Graig Lwyd stone from Penmaen-mawr Mountain (Group VII). Other finds of interest were reported to me by Mr. T. J. Evans, Geography Master at Aberdare County Grammar School for Boys, having been found by a pupil on Mynydd Aberdar. The first is a fragment from a fine arrow-head of willow-leaf form, and adds to the evidence of Neolithic occupation of the Glamorgan uplands. It was found on a recently constructed Forestry Commission path at SO 028034. About 200 yards north-north-west part of a trapeze- shaped flint arrowhead was found in a similar position. This type is rare in south-east Wales and much commoner in the central Marches: no doubt its use is related to the spread of the Secondary Neolithic cultural group from the English Midlands (I. LI. Foster and L. Alcock (ed.), Culture and Environment, 31). Other surface finds have been made by members of the Rhondda Society, on the ridge between Blaen Clydach and Gelli and near the head of the Rhondda Fach and an account will be given of these when fuller details are available. The only prehistoric excavation during the past year was that carried on, after preliminary work in 1970, by members of the Cardiff Archaeological Society at an unrecorded round cairn north- west of Maes-yr-hwyaid Farm, Welsh St. Donats (ST 03657555). The work so far has not gone beyond careful trenching to establish the structural characteristics of the cairn, and this has firmly established the character of the site as a well-preserved occupation surface, with small sherds of Beaker, and more than one burial pit. It is hoped to explore the main features in 1972. H. N. Savory
