The cash revenues and imputed incomes from country food harvests were calculated from interviews with eight full-time hunting and ten wage-earning Inuit for 1984 at Holman, Northwest Territories. Using a substitution value of Can$10.56/kg ($4.79/lb) for country food harvests, the combined income (cash + imputed food value) of the two groups was very similar. Full-time hunters produced country food at $1.01/kg ($0.46/lb). while wage earners spent $5.7 I/kg ($2.59/lb) on their harvest. Full-time hunters harvested surpluses of food which would feed another fourpeople outside their immediate family. Wage earners ended the year with almost twice the cash balance of full-time hunters, whose main monetary revenuecomes from guiding trophy hunters. The precarious cash economy of the full-time hunters who provide a significant part of the food for the village should be a subject of concern and attention when considering the future well-being of the northern economy.

During Leg 119 of the Ocean Drilling Program, between December 1987 and February 1988, six holes were drilled in the Kerguelen Plateau, southern Indian Ocean, and five in Prydz Bay at the mouth of the Amery Ice Shelf, on the East Antarctic continental shelf. The Prydz Bay holes, reported here, form a transect from the inner shelf to the continental slope, recording a prograding sequence of possible Late Paleozoic to Eocene continental sediments of fluvial aspect, followed by several hundred metres of Early Oligocene (possibly Middle Eocene) to Quaternary glaciallydominated sediments. This extends the known onset of large-scale glaciation of Antarctica back to about 36–40 million years ago, the sedimentary record suggesting that a fully developed East Antarctic Ice Sheet reached the coast at Prydz Bay at this time, and was more extensive than the present sheet. Subsequent glacial history is complex, with the bulk of sedimentation in the outer shelf taking place close to the grounding line of an extended Amery Ice S helf. However, breaks in the record and intervals of no recovery may hide evidence of periods of glacial retreat.

Stomachs of 171 vertebrates (two species offish, eight of birds and twoof seals) from Hornsund, Svalbard, were collected between 7 September and 5 October 1984. Arctic cod Boreogadus saida and the amphipod Pamthemisto libellula were the main prey species of black guillemots Cepphus grylle, little auks Alle alle, puffins Fratercula arctica, Brunnich's guillemots Uria lomvia, kittiwakes Rissa tridactyla and ringed seals Phoca hispida. Fulmars Fulmarus glacialis preyed mainly on the squid Gonatusfabricii and the polychaete Nereis irrorata. Eiders Somateria mollissima preyed mainly on bivalves and on the amphipod Gammarellus homari. G. homari and Gammarus oceanicus were the most important prey species of striped snailfish Liparis liparis, while shorthorn sculpin Myoxocephalus scorpius mainly preyed upon G. homari and Anonyx sarsi. Glaucous gulls LOTUS hyperboreus took many different prey including birds and tundra plants. Only one bearded seal Erignathus barbatus stomach with content was available for this study.

Many northern regions of North America have come to rely heavily on extraction of non-renewable resources for their income, at the expense of traditional land-based economies. Such extraction leads to boom and bust income, destructive to long-term planning for sustainable development. Natural resource trust funds, as exemplified in Alberta, Alaska, Montana, Wyoming and New Mexico, would help to provide the stability that is currently lacking in Yukon and the Northwest Territories. Maintained by setting aside part of the current income from non-renewable resources, they yield capital and income that can be used to encourage the mixed, self-sustaining local communities appropriate for the North.

This research bibliography gives a brief ecological account of lies Crozet (Terres Australes et Antarctiques Francaises) and lists over 370 studies in terrestrial and freshwater ecology (including laboratory studies) under five headings — history and general aspects, earth sciences, botany, invertebrate fauna, vertebrate fauna.

In 1956 the United States government allowed the Territory (now State) of Alaska to select 404,695 hectares of land to provide specifically for mental health services for Alaskans. State legislatures have since tried to place this land into private ownership because of the ‘highest and best use principle’ of land management. ‘Strict usage principle’ opponents have countered with legal action, the result of which is to place the land in a status where it serves neither proponent groups. The question raised by this piece of land history is whether, in a federalism such as the United States, it is possible to use land to serve dedicated social needs.

This article seeks to explain the doctrine concerning sovereignty in Antarctica articulated by Charles E. Hughes, a former US Secretary of State, and to account for its persistence in underpinning US Antarctic policy. The doctrine was part of the New Imperialism — the surge of colonial expansion and spheres of influence that occurred in the late 19th and early 20th centuries. US imperialism sought to establish an ‘open door’ international order to exploit America's growing economic power; the Hughes doctrine extended this policy into Antarctica, preserving US access to all of the region by denying recognition of claims by other countries.

We regret that, in the article by Yakushkin and Barr on ‘The introduced musk-oxen of Poluostrov Taymyr’ (Polar Record 24 (151): 321–24, 1988), a passage was lost in transcription from the paragraph on p. 323 headed ‘Herding and population’. The following replaces lines eight and nine:

expanded enormously. By the start of wintera typical herd expands to 40–65 individuals. Adjacentherds, groups and single bulls merge with the main herd; as a result it now includes several dominant and subdominant bulls. No serious conflict occurs between the bulls during winter, however.
