Energy-dispersive X-ray fluorescence (EDXRF) was used to determine the minor and trace element composition of 54 sherds of pottery dating from the Final Jomon to Okhotsk periods. The majority of the sherds came from Rishiri Island, Japan. Principal component (PC) scores were calculated using the log transformed concentration values, and groups were sought in the PC scores using kernel density estimates (KDEs). Two main groups were found in the data; linear and quadratic discriminant analysis classified both groups successfully. Significant differences in the concentrations of Cu, Fe, K, Nb, Pb, Rb, Th and Zr were found to exist between the two groups. The lack of correspondence between chronological ware types and geochemical groups implies that the same raw materials and paste recipes were in use during the Epi-Jomon and Okhotsk eras on Rishiri Island. One possiblity is that the EpiJomon and Okhotsk potters used the same clays and tempers, since no other alternatives were available. Alternatively, the Okhotsk potters could have adopted the same paste recipes as the Epi-Jomon potters, or the Okhotsk pottery tradition could be descended from the Epi-Jomon pottery tradition.

Federation in Central America. The organization of an international court in Central America was greatly facilitated by the fact that since their independence began the five Central American states have had a tradition of solidarity. This tradition has persisted in spite of frequent dissensions, and it has been expressed in numerous attempts at federation. Under the Spanish régime, the Vice-royalty of Guatemala included in its five provinces the territory of what is now the five states. It was this dependency which declared its independence in 1821. Two years later the Republic of the United States of Central America was formed, and it continued for some years. Later attempts at union were made in 1835, 1842, 1847, 1852, 1889, and 1895, all of them more or less abortive, as was the latest attempt in 1921. Unanimous agreement of the five states was always difficult to achieve; distances were great and communications difficult; and no pressing need made union imperative. Yet the attempts at federation were renewed from time to time, over a period of a century. They had the effect of encouraging cooperation in many fields, and led to the efforts in 1902, 1907 and 1921 to create a judicial agency for the handling of disputes between the five states.
We are now approaching the end of the first decade following the World War. Perhaps we are sufficiently removed from the heat and passion of that struggle to attempt to gauge the progress which the world has made in the development of international law since it was ended. Ten years is a brief period in any field of history; but before this decade was begun, most of us felt that it was going to see great things accomplished toward broadening and strengthening and extending the law by which the relations of states are governed. The war brought a challenge to our international legal order which could hardly have failed to create for our generation an opportunity to leave an impression on international law, such as has been left by no other generation in the three hundred years since the time of Grotius. As the decade is ending, and as our generation begins to find its energies so absorbed in other tasks, an appraisal of the progress we have achieved may enable us to judge the use we have made of our opportunity and the extent to which it still exists.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
