Alaska and its Resources. Boston, 1870. The classification followed is practically the same as is given in the author’s article in the Proceedings of the American Association for the Advancement of Science. 1877. Dall (William Healey). Tribes of the extreme northwest. In Contributions to North American Ethnology (published by United States Geographical and Geological Survey of the Rocky Mountain Region). Washington, 1877, vol. 1. This is an amplification of the paper published in the Proceedings of the American Association, as above cited. The author states that “numerous additions and corrections, as well as personal observations of much before taken at second hand, have placed it in my power to enlarge and improve my original arrangement.” In this paper the Orarians are divided into “two well marked groups,” the Innuit, comprising all the so-called Eskimo and Tuskis, and the Aleuts. The paper proper is followed by an appendix by Gibbs and Dall, in which are presented a series of vocabularies from the northwest, including dialects of the Tlinkit and Haida nations, T’sim-si-ans, and others. 1877. Gibbs (George). Tribes of Western Washington and Northwestern Oregon. In Contributions to North American Ethnology. Washington, 1887, vol. 1. This is a valuable article, and gives many interesting particulars of the tribes of which it treats. References are here and there made to the languages of the several tribes, with, however, no attempt at their classification. A table follows the report, in which is given by Dall, after Gibbs, a classification of the tribes mentioned by Gibbs. Five families are mentioned, viz: Nūtka, Sahaptin, Tinneh, Selish, and T’sinūk. The comparative vocabularies follow Part II. 1877. Powers (Stephen). Tribes of California. In Contributions to North American Ethnology. Washington, 1877, vol. 3. The extended paper on the Californian tribes which makes up the bulk of this volume is the most important contribution to the subject ever made. The author’s unusual opportunities for personal observation among these tribes were improved to the utmost and the result is a comparatively full and comprehensive account of their habits and character. Here and there are allusions to the languages spoken, with reference to the families to which the tribes belong. No formal classification is presented. 1877. Powell (John Wesley). Appendix. Linguistics edited by J. W. Powell. In Contributions to North American Ethnology. Washington, 1877, vol. 3. This appendix consists of a series of comparative vocabularies collected by Powers, Gibbs and others, classified into linguistic families, as follows: Family. 1. Ká-rok. 2. Yú-rok. 3. Chim-a-rí-ko. 4. Wish-osk. 5. Yú-ki. 6. Pómo. 7. Win-tūn´. 8. Mūt´-sūn. 9. Santa Barbara. 10. Yó-kuts. 11. Mai´-du. 12. A-cho-mâ´-wi. 13. Shaś-ta. 1877. Gatschet (Albert Samuel).
