B. G. J. Upton

ABSTRACTIn the early Carboniferous, the portion of continental crust that now constitutes Scotland lay within the hinterland of a large continent that extended westwards to what is now the western parts of North America, eastwards to what is now the Urals and northwards towards what is now Arctic Canada, Greenland, Scandinavia and Russia. Open ocean probably lay at between 600 and 1000 km to the south. Whereas mountainous terrane lay to the north of the Highland Boundary fault, the Scottish Midland Valley, like the Northumberland Trough further south, was a region of low relief subject to periodic marine incursions.A period of block faulting and concomitant basaltic volcanism commenced at the beginning of the Carboniferous at c. 350 Ma. This had manifestations in various regions of the British Isles from the south-west of England to the west of Ireland and as far north as the Midland Valley (Francis 1978, 1991; Upton 1982; Cameron and Stephenson 1985).

Five deer species occupy North America: caribou (3.6 × 106individuals), moose (1.1 × 106), white-tailed deer (28.5 × 106), mule deer (5.0 × 106) and wapiti (1.1 × 106). Caribou characterise the north of the boreal forest and the tundra, whereas moose dominate in coniferous and mixed forests growing further south. White-tailed deer are typical of the deciduous forests of the east while mule deer replace them in the mountainous terrain of the west. Wapiti possess the smallest range, mostly adjacent to the prairies to the west. The two large obligate carnivores preying on deer show a reduced distribution: wolves are almost restricted to Canada, and cougar to the mule deer range. We determined the current status of each species with the help of a questionnaire mailed to all jurisdictions harbouring deer. Most reports of threatened populations concerned caribou whereas many jurisdictions declared overabundance of white-tailed deer and wapiti. Hunting was allowed for all species when they abounded in a jurisdiction. Hunters harvested annually 7.0 × 106deer on the continent, 87% being white-tailed deer. The two species that caused most conflicts with humans had the highest harvest rate: 16-17%. In terms of biomass, white-tailed deer and wapiti yielded the highest harvests, with 55 and 39 kg × km-2of range, respectively. The average standing biomass of deer in winter ranged between 28 kg × km-2in Nevada to 901 kg × km-2in Indiana. The lowest standing biomasses occurred in the boreal forest (predators), in the prairies (agriculture) and in the south-west (aridity), and the highest ones in the south-east, where only white-tailed deer is present. The current abundance of deer in North America parallels, in general, the primary production of the landscape (r2= 0.38; P < 0.0001), but predators and human activity modify this pattern.

In view of the importance of a pure milk supply, we considered that it might be of interest to examine chemically, microscopically, and bacteriologically, a number of specimens of milk coming into the Metropolis for which purpose we decided to select samples from the various counties, the milk of which is consigned to London. We found that milk so consigned comes from about twenty-six counties extending from Derby in the North, to Hampshire and Devonshire in the South and South-West, and from Hereford in the West, to Norfolk in the East.

The Somerset Levels are the largest area of low-lying ground in south-west England, covering an extensive region between the highlands of Exmoor, the Brendon Hills and the Quantock Hills to the west, and the Cotswold and Mendip Hills to the east (Pl. XXIII, inset). The Quantock Hills and the Mendip Hills directly border the Levels themselves, and reach heights of over 250 metres above sea level. The valley between extends to 27 metres below sea level, but is filled to approximately the height of the present sea by a blue-grey clay. The Levels are bisected by the limestone hills of the Poldens, and both parts have other smaller areas of limestone and sand projecting above the peat deposits that cap the blue-grey clay filling. In this paper we are concerned with the northern part of the Levels, an area at present drained by the River Brue.The flat, peat-covered floor of the Brue Valley is some six kilometres wide and is flanked on the north by the Wedmore Ridge, and on the south by the Polden Hills (Pl. XXIII). In the centre of the valley, surrounded by the peat, is a group of islands of higher ground, Meare, Westhay, and Burtle. These islands, which would always have provided relatively dry ground in the Levels, are linked together by Neolithic trackways of the third millennium B.C. Several of these trackways formed the basis of a paper in these Proceedings in 1968 (Coles and Hibbert, 1968), which continued the work of Godwin and others (Godwin, 1960; Dewar and Godwin, 1963).

The huasteca region in northeastern Mexico covers sections of the six states of Tamaulipas, Veracruz, San Luis Potosí, Hidalgo, Puebla, and Querétaro. Its boundaries are approximately the following: to the north the river Soto la Marina, known in the sixteenth century as the Rio de las Palmas; to the south the Rio Cazones; to the east the Gulf of Mexico and to the west the mountainous section of the eastern Sierra Madre.The Christian conversion of the Huasteca began, no doubt, in 1518 with the expedition of Juan de Grijalva, who actually sailed as far north as Tuxpan and Tamiahua in the Huastec region of the state of Veracruz. John Diaz, a priest, accompanied this expedition. In 1519 Francisco de Garay, then in Jamaica, sent Alonso Alvarez de Pineda to Tampico and the Río Panuco, where he stayed some time and made contact with the Huastecs who belong to the great Maya family.

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.

Among over 1800 boxes of Sir Arthur Evans's finds now stored in the Stratigraphical Museum at Knossos, at least 150 contain Greek pottery from Subminoan to Classical. A systematic study of this material, in relation to its recorded find spots, throws new light on the eastern part of the early Greek town, bordering the site of the Minoan Palace. Above the Palace itself, fresh evidence is produced, and fresh interpretation offered, for the Greek sanctuary described by Evans. In its immediate surroundings, there are signs of busy domestic and industrial life in the early Greek town above the South-West Houses, the West Court, the Theatral Area, and the Pillared Hall outside the North Entrance to the Palace. Greek occupation is also noted above the House of Frescoes, the Little Palace and the Royal Villa. A wider aim of this article is to trace the limits of the early Greek town of Knossos, both of its original Early Iron Age nucleus surviving from Late Minoan times, and of its spacious extension towards the north in the late eighth and seventh centuries BC.

An unusual occurrence of ultrabasic material was located in the eastern Sukkertoppen region during the reconnaissance mapping programme of 1977, the findings of which were described by Allaart et al. (1978). It occurs on a small exposure on the west side of a north-pointing peninsula in the middle of the large nunatak Majorqap alangua (65°53'N, 50°40'W), to the north-east of the Majorqaq valley (Hall, 1978, fig. 21). The area is composed predominantly of a suite of granulite facies granitic gneisses which contain numerous enclaves of pyroxene-bearing amphibolites, and locally anorthositic and gabbroic rocks similar to those seen in the Fiskenæsset anorthosite complex (Myers, 1975). The gneisses in the centre af the nunatak are highly irregular in orient at ion, occupying the complex interseclion af closures af at least two major fold phases. A belt af amphibolitcs forms the cliff at the south-west tip af Majorqap alangua. Related rocks occur in arnphibolite facies in the acea around the lakc Qardlit taserssuat immediately to the soulh (Hall, 1978).

The casa degli amanti (house of the lovers), at the south-west corner of the insula, falls into two fairly distinct halves: the atrium complex, oriented on the street to the west, and the peristyle with its surrounding rooms, oriented on the street to the south and on the property boundary to the east. In the atrium complex, the atrium is misplaced to the south of the central axis, allowing space for two large rooms to the north, one of which was possibly a shop or workshop (5.50 m. × 4.70 m.), with a separate entry from the street (I 10, 10), while the other (5.80 m. × 4.50 m.), decorated with mythological wallpaintings and provided with a wide opening on to the peristyle, must have been a dining-room or oecus (room 8). Each of these had a segmental vault rising from a height of about 3.50 m. at the spring to slightly over 4 m. at the crown. In the first the vault is missing, but the holes for some of its timbers are visible in the east wall and a groove along the north wall marks the seating for the planking attached to them; at a higher level, in the north and south walls, are the remains of beam-holes for the joists of the upper floor or attic (see below). The arrangements in room 8 are now obscured by the modern vault constructed to provide a surface for the reassembled fragments of the ceiling-paintings; but the shape of the vault is confirmed by the surviving plaster of the lunettes, while a beam-hole for the lowest of the vault-timbers is visible above the corner of the western lunette in an early photograph (Superintendency neg. C 1944). The shop I 10, 10 had a small window high in the street wall to the south of Its entrance; whether there were any additional windows above the entrance, it is impossible to say, since this part of the wall is a modern reconstruction. Room 8 was lit by a splayed window cut in the angle of the vault and the eastern lunette, opening into the upper storey of the peristyle.
