INTRODUCTION. The bibliography of North American geology, including paleon tology, petrology, and mineralogy, for the years 1921 and 1922 con tains publications on the geology of the Continent of North America and adjacent islands and on Panama and the Hawaiian Islands. It includes textbooks and papers of general character by American au thors, but not those by foreign authors, except papers that appear in American publications. The papers, with full title and medium of publication and explanatory note if the title is not fully self-explanatory, are listed under the names of their authors, which are arranged in alphabetic order. The author list is followed by an index to the literature listed. The bibliography of North American geology is comprised in the following bulletins of the United States Geological Survey: No. 127 (1732-1892); Nos. 188 and 189 (1892-1900); No. 301 (1901-1905); No. 372 (1906-7); No. 409 (1908); No. 444 (1909); No. 495 (1910); No. 524 (1911); No. 545 (1912); No. 584 (1913); No. 617 (1914); No. 645 (1915); No. 665 (1916); No. 684 (1917); No. 698 (1918); and No. 731 (1919-1920). A cumulation of these bulletins down to 1918, inclusive, consisting of an author list giving titles of papers and brief citations and an index, has been recently issued under the general title "Geologic literature on North America, 1785-1918," in two parts Part I, Bibliography (Bulletin 746), and Part II, Index (Bulletin 747). 1
