Note 1254 — Chapter VI · (continued 2)

Dr. Kohl’s studies on the course of geographical discovery along the Pacific coast were never published. He printed an abstract in the United States Coast Survey Report, 1855, pp. 374, 375. A manuscript memoir by him on the subject is in the library of the American Antiquarian Society (Proceedings, 23 Apr. 1872, pp. 7, 26) at Worcester. So great advances in this field have since been made that it probably never will be printed. There is a chronological statement of explorations up the Pacific coast in Duflot de Mofras’ Exploration du territoire de l’Orégon (Paris, 1844), vol. i. chap. iv.; but H. H. Bancroft’s Pacific States, particularly his Northwest Coast, vol. i., embodies the fullest information on this subject. In the enumeration of maps in the present paper, many omissions are made purposely, and some doubtless from want of knowledge. It is intended only to give a sufficient number to mark the varying progress of geographical ideas.
