    The paper aims to discuss the ethnic play and games of Inuit of Inuqujuak village, Quebec, Canada, from the view point of acculturation. The date is mainly the oral information given by Inuit informants when the anthropological field work was done by the author in December 1995. Followings were obtained, 1. 12 out of the 30 items (boxing, archery, wrestling, rope skipping with a float, vertical jumping in a Igulu, keep away games, jumping high kick, finger pulling, ear pulling, mouth pulling, arm pulling and neck pulling) disappeared from 1960s to 1980s. 2. Most of the disappeared items related strongly to the hunting which was a main traditional economics of Inuit, so the disappearance seems to have followed the economic change. 3. In those days when the Inuit traditional life operated, homes and regional play meetings worked as a transmit medium of play and games among generations. As the permanent residing proceeded, however, they worked no more effectively, and TV took the place partly instead. The alternative transmit mediums were not created yet in Inuqujuak when the author did his field work.

    Japanese fresh-water mysids are treated in this paper and their ecology is compared with that of a glacial marine relict Mysis relicta.
    Japanese relict Mysidacea shall be identified with either of Neomysis awatschensis and N. nigra. Those from Etorohu-Sima of the Kurile Islands, Hokkaidô and the Kwantô Plain belong to the former, and those from the Japan Sea coast of southern Honsyû are refered to the latter.
    The Neomysis-l ?? kes are all shallower than 22.5m, lying at lower altitude than 10m., within 18km. from the nearest sea. They are accepted as relict lakes, and neither any effect of glacial process nor any active migration of the animal are necessary for Neomysis to reach them, since it is nothing other than the original marine fauna adapted to the change of salinity in them.
    The Neomysis-lakes of Etorohu-Sima were nearly homothermal at less than 15°C in July-August of 1932. In Tôro-ko, Hokkaidô, the temperature may reach 27.5°C at the surface and was 22°C at all strata in October. In Honsyû, the surface water may rise above 30°C and the bottom water above 20°C in summer. Thus N. awatschensis and N. nigra seem to have a wide temperature range, being contrasted to M. relicta which is a typical stenothermal organism. M. relicta is a steno-oxybiont appearing in Tanytarsus-lakes. If it appears in Chironomus-lakes, it keeps off the hypolimnion with insufficient oxygen to be restricted to the cool well-aerated middle strata. Japanese Neomysis-lakes are all eutrophic plumosus-type, and in. some of them the oxygen in the hypolimnion may become absent in summer. There is no relict lake of Tanytarsus-type in Japan
    Both N. awatschensis and N. nigra seem as M. relicta to multiplicate in winter season.

    北米大陸における冬季の降水量分布と気流系の関係,および最近の気候変動の実態を明らかにすることを試みた. 1951~1978年の1月と2月の月降水量を主成分分析した結果,合衆国東部と北米西岸部における降水量の変動をそれぞれ説明する第1,第2成分,すなわち四つの主要な降水量偏差分布型が得られた.一方,同期間の月平均500mb面高度の主成分分析によっても,四つの主要な成分と四っの主要な気流型が得られた.各降水量偏差分布型が卓越した時の500mb面高度分布合成図を用いて,これらの型の関係を検討し,各降水量偏差分布型は,それぞれ四つの主要な気流型と対応関係のあることがわかった.
    冬季における気流系の変動傾向としては, 1950年代前半は東西流が卓越し, 1960年代前半と1970年代後半は南北流が卓越した.また, 1963年頃以降,高緯度の寒冷域(極うず)が北米において拡大した.対象期間を通して,降水量は合衆国東部で減少傾向にあった.

    In this paper, the administrative aspects of Aboriginal issues are discussed. Constitutionally, the federal government is responsible for the status Indians and Inuits because of the British North America Act of 1867. Section 91 (24), and one particular department, the Department of Indian Affairs and Northern Development (DIAND) has this responsibility. However, on careful examination, this perception is not entirely correct. Administrative interaction is extremely complicated, and any single generalization may not illustrate the entire picture.
    First, when we study the relationship between governments and the aboriginal peoples, we can point out at least seven types of government administration. For example, the status Indians could benefit from government programs such as free education and medical care as long as they reside on Indian reserves. And a band government, which is recognized by DIAND as a legitimate political unit on a reserve, is responsible for policy initiation and implementation. In this case, we can find a bilateral relationship between Ottawa and the band government, and the BNA Act recognizes this interaction constitutionally. However, due to federalism (division of powers between federal and provincial governments) there are different types of exceptions to aboriginal administration in Canada.
    Second, at least three policy trends in recent aboriginal policy can be identified: functional decentralization, federal-provincial coordination and native participation. In the past decades, only DIAND was responsible for the status Indians and Inuits. But since the early 1970's, several federal departments and agencies began to provide their services to native Canadians. Approximately, one-third of the budget for the native program is implemented by non-DIAND departments. The federal-provincial coordination covers many areas of service such as policing, education and health care. The Native Canadians also began to assert their views and demands when the native programs were implemented. As these trends indicate, the administration of native policy in Canada cannot be carried out without referring to the transformation of Canadian federalism.
    Third, several provincial governments began to establish native branches such as SAGMAI in Quebec.
    How do we evaluate the Canadian situation theoretically? Here, it is possible to identify two approaches to aboriginal (or ethnic) administration: liberal integration and pluralism (or special status). The liberl integration approach indicates the eliminations of a special status — no ethnic group would be given special programs or rights by a government, and equality of all citizens as well as all ethnic groups is assumed. While the second approach may not abandon liberal-integrationism completely, a group could possess a special status or right as a result of historical and geographical reasons. In Canada, many Native peoples support a theory of “citizens plus, ” which recognizes the Aboriginal Canadians' unique historical status in North America.
    While this paper deals with only the Canadian situation, it seems relevant to examine administrative/policy aspects of ethnic/minority problems comparatively.

     The Earth is the only planet where liquid water and life have existed through geologic time. Therefore, it is important to investigate the surface environments of the early Earth to understand its early life. However, little is known about the environments of the early Earth because of a lack of geologic evidence. Recently, > 3.95 Ga supracrustal rocks including carbonate rocks, named Nulliak supracrustal rocks, were found in the Saglek Block, northern Labrador. The seawater composition of the early Earth and vestiges of life from the oldest supracrustal rocks are investigated. The carbonate rocks occur in four areas of the Saglek Block, and are accompanied by meta-chert and meta-pelitic rocks or metamorphosed banded iron formation and meta-basalt. They all are regionally metamorphosed under the amphibolite or the granulite facies conditions (> 500°C) to yield metamorphic minerals such as amphibole and pyroxene. The whole-rock compositions of major, trace, and rare earth elements of the carbonate rocks are assessed. The carbonate rocks are composed of CaO, MgO, FeO, and SiO2 with trace amounts of Al2O3, Zr, and Ba. Carbonate rocks with low Al2O3 (< 0.2 wt.%), Zr (< 2 ppm), and Ba (< 5 ppm) contents are selected to avoid the influences of detrital and volcanic materials on their compositions. Post-Archean Australian Average Shale (PAAS)-normalized Rare Earth Element (REE) patterns of detritus-free samples show flat to slightly light REE-depleted patterns with positive La, Eu, and Y anomalies and without a Ce anomaly. The positive La and Y anomalies indicate that the carbonate rocks originated from chemical sediments precipitated from seawater. The lack of the Ce anomaly indicates that Eoarchean seawater was anoxic. Because the carbonate rocks accompanied by the pelitic rocks have obvious Eu anomaly, even seawater near a continent had the Eu anomaly and was widely dominated by hydrothermal influx. Pelitic rocks, conglomerate, carbonate rocks, and chert nodules within the carbonate rocks in St. John's Harbour South, St. John's Harbour East, Shuldham Island, and Big Island contain graphite, whereas no graphite is found in the sedimentary rocks in Pangertok Inlet. Some of the pelitic rocks and conglomerate have low δ13Corg values with a nadir of −28.2‰, which is comparable to the minimum value of δ13C values of graphite in the Isua supracrustal belt. The δ13Corg values of graphite in the politic rocks show a weak negative correlation with total organic carbon contents. On the other hand, carbon isotope values (δ13Ccarb) of carbonate in the carbonate rocks range from −2.6‰ to −3.8‰. The δ13Corg values positively correlate with the metamorphic grade and negatively with total organic carbon contents. The correlation indicates that the variation in δ13Corg values is possibly due to carbon loss during metamorphism. It is concluded that the large fractionation between the δ13Ccarb and δ13Corg values, up to 25‰, provides the oldest evidence for organisms over 3.95 Ga.
