SynopsisThe Riccarton and Raeberry Castle beds in Kirkcudbrightshire have hitherto been regarded as Wenlock in age, and the Hawick Rocks as Llandovery. Detailed mapping and revision of the graptolite faunas shows that the Raeberry Castle beds are Llandovery and the Riccarton beds Wenlock in age. On structural evidence the Hawick Rocks south of Kirkcudbright are considered to be younger than the Riccarton beds. The Riccarton beds in the area are formally defined as the Ross Formation and the Raeberry Castle beds as the Raeberry Castle Formation. Directional data suggest that the sediment forming the Raeberry Castle Formation was derived from the west and the sediment forming the Ross Formation and Hawick Rocks was derived from the north-east.

Early in 1963 much of the land occupied by the Roman building at Fishbourne was purchased by Mr. I. D. Margary, M.A., F.S.A., and was given to the Sussex Archaeological Trust. The Fishbourne Committee of the trust was set up to administer the future of the site. The third season's excavation, carried out at the desire of this committee, was again organized by the Chichester Civic Society.1 About fifty volunteers a day were employed from 24th July to 3rd September. Excavation concentrated upon three main areas; the orchard south of the east wing excavated in 1962, the west end of the north wing, and the west wing. In addition, trial trenches were dug at the north-east and north-west extremities of the building and in the area to the north of the north wing. The work of supervision was carried out by Miss F. Pierce, M.A., Mr. B. Morley, Mr. A. B. Norton, B.A., and Mr. J. P. Wild, B.A. Photography was organized by Mr. D. B. Baker and Mrs. F. A. Cunliffe took charge of the pottery and finds.

This paper is devoted to a study of the horned-cairns of the North-east of Ireland and their associated artifacts. The term ‘horned-cairn’ is used to describe those segmented gallery-graves set in a long cairn and entered from a semi-circular forecourt delimited by an orthostatic facade. It is realized that this term is not altogether satisfactory, but it has the virtue of brevity and its usage is now well established. Some contemporary Irish prehistorians, notably Professor Ruaidhrí de Valéra, have suggested the term ‘court-cairn’ for all the manifestations in Ireland of the segmented gallery-grave having elaborate structural forecourts. This would include cairns in the West of Ireland with completely enclosed courts (described as court-cairns in this paper) as well as horned-cairns proper. The confusion which might arise from the use of such terms as ‘full court-cairn’, ‘half court-cairn’, ‘forecourt-cairn’ and the like have decided the present writer to retain in this paper the simple terms ‘horned-cairn’ and ‘court-cairn’.This study is divided into two main sections. The first is descriptive, being concerned with horned-cairns and associated artifacts and the second attempts to place the Carlingford Culture as a whole in its context in prehistory. In view of the paucity of detailed information about court-cairns, particularly the almost complete lack of excavation, no detailed study is made of these. At the time of going to press it is understood that a paper by Professor de Valéra on the court-cairns of the west is about to be published in the Proceedings of the Royal Irish Academy.

The surviving plaster on the walls of this entranceway consisted of a high pink socle, delineated in red, with a white zone above. Ling observed that this overlay an earlier First-Style decoration on the east wall and that it had been patched in antiquity. Breaches are found in both the east and west walls. Outside the entrance, to either side, is a masonry bench (east bench: l.: 2.1 m, d.: 380 mm; west bench: l.: 2.4 m, d.: 460 mm), both much damaged. Finds within the entranceway consisted of bronze and iron studs, undoubtedly from the house door. Remains of plastered decoration survive on the south wall. Elia recorded a yellow dado, surmounted by a red band, with white plaster above. There is a breach in the north-west corner through to Unit no. 9, above a blocked doorway. At the centre of this front hall is a tufa impluvium (2.4 m × 2.1 m). In the north-west corner, 1 m above the pavement, were found: a small bronze ring; a bronze stud, similar to those in the entranceway and probably also from the front door; a fragment of a stone mortar or hand-mill; some glass beads; a small shell; and two bronze quadrantes, one of Nero dated ad 64. The fragmentary or loseable nature of these items suggests that they were disturbed from the ground level. Other small loseable items were found in the north-east corner: a small glass bottle, probably a toilet item; and possibly five more coins. One metre from the west side of the impluvium were found: another part of a hand-mill; two large stone weights; at least fifty-three lead weights, probably from a loom; and two other spherical stones, possibly also weights. The large number of lead weights is comparable with the quantity found under the stairway in room i of the Casa del Principe di Napoli. Another comparable group of forty loom weights was found together in a pit at Zugmantel. As Jongman noted, this amount would be equivalent to that required for one or perhaps two warp-weighted looms. It is therefore commensurate with the existence of such a loom, or looms, in this area, or of replacement loom weights, for domestic use.

In November 1926 the excavators recorded moving lapilli from in front of this house and from the entrance but no finds were reported in these areas. On 8 July 1932 they recorded removing disturbed volcanic deposit from the middle levels in the northeast area of this insula. A breach (min. h.: 2 m), now patched, in the south end of the west wall of room 2 and 1.05 m above the floor, presumably penetrated into this space and documents disturbance after ad 79. Elia observed that the room had been covered and had been divided for all or part of its length by a ‘tramezzo ligneo’ which Ling interprets as a wooden partition to screen the stairway. In the north-east corner, are three masonry steps from a stairway which Ling argued ascended along the east wall. Ling argues that the installation of this stairway would have put out of commission the recess and lararium painting (dimensions: 0.55 m × 0.4 m) behind it. The remains of a late Third Style decoration are found on the walls. The loose finds from near the north entrance of this space and from near the entrance to room 3 were predominantly door-fittings, with the possible exception of a small marble base. A small key reported in the latter location may originally have been from storage furniture but was unlikely to have been in use as no other remains of such furnishings were recorded. The only other find in this area was a glass vessel of unknown type. Elia called this room an ‘atrium’. The finds are not particularly diagnostic but, even if this area was disturbed, they hint that it had been relatively unencumbered with furnishings, probably serving predominantly as a reception and access area for the rest of the house. The breach in the south end of the west wall of this room implies that it may have been disturbed after ad 79. The walls had a simple painted decoration but this room had no evident fixtures. According to Elia it was an ‘oecus’. The limited ceramic finds (a jug, a terra sigillata dish, and a lamp) are associated with lighting and probably with the serving or storage of foodstuffs.

The area embraced in this paper consists of that part of Pembrokeshire which lies to the north and north-east of St Bride's Bay. Bounded on the west by St George's Channel and on the north by Cardigan Bay, it extends to the north-east as far as the mouth of the river Teifi, near Cardigan.That part of the country which lies in the immediate neighbourhood of St David's has, through the laborious researches of the late Dr Hicks and others, become well-known to geologists, and may now be regarded as classic ground. The solid geology of this promontory has given rise to much discussion, and has, perhaps, attracted more attention than that of any other part of the Principality. The reason for this great interest is to be sought in the facts that the rocks of this area are of a very great antiquity, and that the sedimentary series contain the remains of some of the earliest organic forms yet found in the earth's crust, whilst the igneous rocks are also displayed in great abundance and variety, and present us, in the words of Sir Archibald Geikie, with “the oldest well-preserved record of volcanic action in Britain.”

The West Sulu Basin lies in the western portion of the Sulu Sea. Republic of the Philippines. It occupies an area in excess of 26,000 square miles (67,000 km2) and is bounded to the west and south by the cordilleran arc extending from the island of Palawan through Sabah and along the Sulu Archipelago to the island of Mindanao. To the north-east, the basin probably extends beyond the edge of the continental shelf in Philippine territorial waters.The basin may be broadly divided into a western platform and an eastern deep: the latter is subdivided by northeast-trending basement ridges into three sub-basins. Sediments deposited in these sub-basins are of Tertiary to Recent age and have been affected by several orogenies and by contemporaneous movements of fault-controlled blocks. This has resulted in truncation and the development of marked erosion surfaces and onlap within the Upper Tertiary section. Many anticlinal features mapped within the basin have resulted from drape over basement highs or from penecontemporaneous growth of these highs.Major unconformities associated with Upper Tertiary tectonic events have been recognized onshore. Extrapolation to offshore areas where these events can be seismically mapped has enabled an interpretative geologic model to be built up. Provisional identification of stratigraphic units and their nature have been made using this model.The Upper Tertiary section within the eastern deep is expected to consist of deltaic and paralic reservoir sands interbedded with, grading into and transgressed by deeper water shale and mudstone with good hydrocarbon source potential. Some limestone lenses may be present.The presence of Lower to Middle Miocene diapiric shale and Plio-Pleistocene intrusives coupled with data of variable quality makes seismic interpretation difficult in some areas. However, several large anticlinal features and a number of stratigraphic and combination traps have been located.A non-commercial discovery of oil and gas has been made in the basin.

About 10 metres south-west of the sixth-century temple of Hera Akraia at Perachora, and nearly due west of the little harbour lies the small courtyard previously known as the ‘Agora’. Since its purpose is not known, it will here be non-committally referred to as the West Court. It was first excavated in 1932, and more fully, under the supervision of J. K. Brock, in 1933, but it was not entirely cleared until 1939, and it was at that time that the Roman house which stood in the middle of the court was demolished. The West Court is discussed briefly (under the name of ‘Agora’) in Perachora 1 and in the preliminary reports of the Perachora excavations. Short supplementary excavations were carried out in 1964 and 1966 to examine certain points of the structure.In shape the West Court is an irregular pentagon, about 24 metres from north to south and the same from east to west (Fig. 1; Plate 91 a, b). It is enclosed on the west, north, and on part, at least, of the east side by a wall of orthostates on an ashlar foundation. For a short distance on either side of the south corner, the court is bounded by a vertically dressed rock face which is extended to the north-east and west by walls of polygonal masonry. At the south-west corner the west orthostate wall butts against the polygonal wall, which continues for about 0·80 m. beyond it and then returns north for about 8 metres behind it.

This discovery was made as a result of rescue excavation in advance of road improvements by the Dorset County Council in the autumn of 1962. The site (NGR SY/99789918) now lies in the north verge of the A31 trunk road, 500 feet towards Wimborne Minster from the new Lake junction to Corfe Mullen, but in 1962 it was still included in field No. 7924, belonging to Lake Farm. Here the land, which forms part of the flood-plain of the Stour, is crossed by a spur of slightly more elevated ground extending north from Willetts Lane. There is a gentle slope westwards from the site towards the Chillwater Stream, which flows north to the Stour after descending from higher ground. The lowlying terrain to the west of this low spur used to be marshland until its reclamation, accounting for the name ‘lake’ given to the locality. The subsoil of the valley-bottom is composed variously of gravel, shingly stones and brown alluvial loam. The original vegetational cover would have been woodland of deciduous type, extending from the floor of the valley up the slope to the south and thinning out to scrub and heath on the gravel plateau 150 feet above the Stour. Today, pasture dominates the scene, with oak prominent only in hedgerow or isolated clumps.The pit to be described below lay just over half a mile to the north-east of the site of one similar in shape and contents that was discovered in a quarry in Corfe Mullen parish some twenty-five years ago.

The following remarks, being the result of a careful examination of a small district of country characteristic of the relations of the trap formations, are perhaps worthy of being recorded; although the general features of the county of Roxburgh have been very clearly stated in a paper by Mr Milne, published in the 15th volume of the Edinburgh Transactions.The outburst of porphyritic trap forming the conspicuous small group of the Eildon Hills, may be stated to be surrounded by the characteristic greywacke of the south of Scotland. It forms an elongated patch on the map, extending from the west end of Bowden Muir in the direction of the town of Selkirk, and running from west-south-west to east-north-east (true) towards Bemerside Hill, on the north bank of the Tweed. The breadth is variable, probably less than is generally supposed; but it cannot be accurately ascertained, owing to the accumulated diluvium which covers the whole south-eastern slope of this elevated ridge. On this account, my observations on the contact of rocks have been almost entirely confined to the northern and western boundaries of the trap, although the other side was examined with equal care.
