The discovery and initial excavation of an unenclosed, timber platform settlement site of Late Bronze Age date is described. The site is located in open Fen just off the Fen-edge at Fengate in an area of well-known prehistoric activity. The site includes the remains of a remarkably well-preserved three-aisled rectangular building, with at least two floor levels still intact. Finds include items of pottery, flint and wood. Current environmental research is outlined and the report concludes with a discussion of the site's role and status.

The megalithic tombs of the Tramore group in County Waterford, south-eastern Ireland, are described and reconsidered. Three are confirmed as passage-tombs, but two are now identified as wedge-tombs. The passage-tombs have their best parallels not in Ireland, but in the Scilly Isles and Cornwall.

An extensively plough-damaged oval barrow of the third millennium bc was excavated. The entire mound had been removed by ploughing. No burials were found under the site of the mound but disarticulated human skeletal material was found in the ditches. The main flanking ditches appear to have silted in naturally with evidence of Beaker activity and Romano-British agriculture in the higher levels. Some evidence of deliberate back-filling, including the burial of carved chalk objects, was found in the ditches at the east end. A single Saxon hut was excavated in the north-east corner of the barrow and a rubbish deposit containing Middle Saxon pottery was found in the upper levels of the ditch in the south-west corner of the barrow.

Eight ring-ditches and several stretches of pit alignment have been excavated between 1981 and 1985, as part of the investigation of an extensive cropmark complex on a gravel terrace in the Upper Severn valley at Four Crosses, northern Powys. Excavation of the ring-ditches, which form part of a more scattered barrow cemetery, has revealed a long and complex pattern of development of barrow types and burial forms in the period between the Middle Neolithic and the Middle Bronze Age. This is compared with the recently published sequence from the neighbouring upland barrow cemetery at Trelystan, and subdivided into four hypothetical phases. There is evidence of activity in the vicinity of some of the sites in the Iron Age, Romano-British, and possibly the early post-Roman period.

The suitability of diatom analysis for provenancing British late neolithic and early Bronze Age ceramics is examined. The Milfield Basin, Northumberland, was chosen for a test programme, as an area with well documented clay sources, defined geology and available pottery samples. The bulk of the pottery sampled was of local origin, or at least need not have been made elsewhere; one sherd, the only possible Beaker sherd sampled, seems to be an import. It is concluded that it is possible to use diatoms in this way, and some of the problems of the technique are discussed, together with possible solutions. Sampling and counting strategies are also discussed.

The pottery of the later prehistoric period in the Western Isles of Scotland displays a variety of decorative styles and forms not found elsewhere on the Scottish mainland. Traditional approaches have attempted to define stylistic sequences or to identify wares to which chronological and cultural labels may be attached. In this study neutron activation analysis was utilized to examine if the distinctions which had been drawn were mirrored by chemical composition. Analysis of clay beds had indicated that the analytical and statistical techniques which were employed were sensitive enough to identify patterns which existed within the data. The results for the later prehistoric ceramics indicated that pottery was probably locally produced and locally distributed and that the clays involved in the manufacture of metalworking moulds and crucibles were different in terms of source or method of preparation from those employed in the manufacture of the more mundane range of domestic vessels.
