Rock Specimens

The new material on which this paper is based has lately been received through Mr. D. Ferguson, who recently investigated the geology of the island, and collected the rocks described in an earlier paper. It consists of twenty-seven rock specimens from the south-eastern end of the island, between Cape Disappointment and Cooper Island, and nine specimens from Gold Harbour on the north-east coast between Cooper Island and Royal Bay. All these were collected by the staff of the South Georgia Co., Ltd., under the instructions of Mr. Th. E. Salvesen, managing director, of Leith.

The East Coast of North Island, New Zealand, is the site of subduction of the Pacific below the Australian plate, and, consequently, much of the basin is highly deformed. An exception is the Raukumara Sub-basin, which forms the northern end of the East Coast Basin and is relatively undeformed. It occupies a marine plain that extends to the north-northeast from the northern coast of the Raukumara Peninsula, reaching water depths of about 3,000 m, although much of the sub-basin lies within the 2,000 m isobath. The sub-basin is about 100 km across and has a roughly triangular plan, bounded by an east-west fault system in the south. It extends about 300 km to the northeast and is bounded to the east by the East Cape subduction ridge and to the west by the volcanic Kermadec Ridge. The northern seismic lines reveal a thickness of around 8 km increasing to 12–13 km in the south. Its stratigraphy consists of a fairly uniformly bedded basal section and an upper, more variable unit separated by a wedge of chaotically bedded material. In the absence of direct evidence from wells and samples, analogies are drawn with onshore geology, where older marine Cretaceous and Paleogene units are separated from a Neogene succession by an allochthonous series of thrust slices emplaced around the time of initiation of the modern plate boundary. The Raukumara Sub-basin is not easily classified. Its location is apparently that of a fore-arc basin along an ocean-to-ocean collision zone, although its sedimentary fill must have been derived chiefly from erosion of the New Zealand land mass. Its relative lack of deformation introduces questions about basin formation and petroleum potential. Although no commercial discoveries have been made in the East Coast Basin, known source rocks are of marine origin and are commonly oil prone, so there is good potential for oil as well as gas in the basin. New seismic data confirm the extent of the sub-basin and its considerable sedimentary thickness. The presence of potential trapping structures and direct hydrocarbon indicators suggest that the Raukumara Sub-basin may contain large volumes of oil and gas.

British School

In June and July of 1954 a team often divers spent just over four weeks exploring the east coast of Chios. The team was based on Emporio in the south-east, where the British School was excavating under the direction of M. S. F. Hood and J. Boardman, and was thus able to rely on the archaeologists there for expert guidance. Most of the underwater work took place in this area, but the team was also able to spend some time exploring the north-east coasts of the island, thanks to Mr. Tom Dupree, who put his yacht Kerynia at their disposal.The main diving equipment consisted of three twin-cylinder aqualungs with three spare twin-cylinder air-tanks, and a compressor to recharge them with air, belonging to the British School at Athens. The purchase of this expensive equipment had been made possible by the great generosity of Lord Kelmsley and the Sunday Times newspaper. Miss Dilys Powell, as representative of the Sunday Times, joined the expedition for two weeks and took an active part in the work.

The principal biological question examined by the investigation was whether the resource of P. ornatus fished in Papua New Guinean waters was the same as that fished in Australian waters. In all, 11 932 specimens of Panulirus ornatus were tagged in Torres Strait and on the north-east coast of Queensland over a 3-year period from February 1980 to March 1983. By June 1984, 300 tagged P. ornatus had been recaptured. Of the 9632 P. ornatus tagged on the east coast of Queensland, none was recaptured in Torres Strait, while most of the 24 recaptures showing movements occurred to the south of the tagging sites. Of the 2300 P. ornatus tagged in Torres Strait, 8 were recaptured at sites to the north-east of the tagging sites in September and October 1980, coincident with the annual breeding emigration of P. ornatus from reefs in Papua New Guinean waters in northern Torres Strait, across the Gulf of Papua to breeding grounds near Yule Island. Results of this tagging study showed that P. ornatus from western Torres Strait also emigrate into Papuan New Guinean waters, where they are fished by both Australian and Papua New Guinean fishermen. However, recapture data also indicated that the population of P. ornatus in south-east Torres Strait and on the east coast of Queensland does not take part in this breeding emigration and may be a separate resource. During the study, 39 berried female P. ornatus were found on the north-east coast of Queensland but none in Torres Strait. The breeding stock near Yule Island may be the source of recruitment to both the Torres Strait and north-east coastal Queensland fisheries.

Basaltic Lavas

Hareøen is an island north-west of Disko in western Greenland. It has the form of a plateau, whose highest point - 512 metres - is found near the south coast. Like the neighbouring parts of Nugssuaq and Disko, Hareøen consists chiefly of Tertiary basaltic lavas. The island first attracted attention on account of the presence of interbasaltic, coal-bearing sediments on the north-east coast. These were already examined by Giesecke in 1811 (Giesecke, 1910) and later among others by Steenstrup (1874) and B.E. Koch (1959). A petrographie investigation of the basalts was first undertaken by Holmes (1919), who described loose fragments rich in K2O. Lavas from the south coast, colleeted and analysed by Pedersen (1970), also have a high content of potash. V. Miinther in the years 1948-49 untertook geological mapping of the island, on which the present investigation is supported (Miinther, in press).

The City

In 1870 the Government of the day had behind it the stronger party in the country; and among its followers in Parliament were the two members for the City of London. Pass a quarter of a century, and come to the Government brought into power by the general election of 1895. Exactly the same two things may be said of it; it too had behind it the stronger party in the country; it too numbered among its followers in Parliament the members for the City of London. Only, whereas the Government of 1870 was Liberal, the Government of 1895 was Conservative. That quarter of a century had witnessed the transfer of the City of London's political allegiance from Liberalism to Conservatism; and therein the City's opinions corresponded to those of the business and moneyed classes generally. So it was, not only in the south of England, but also in the Midlands and Lancashire; though not yet at all to the same extent in Yorkshire, the north-east coast, or Scotland.
