By JOHN M. NICKLES. INTRODUCTION. The bibliography of North American geology, including paleon­ tology, petrology, and mineralogy, for the year 1915 follows the plan and arrangement of its immediate predecessors. It includes publications bearing on the geology of the( Continent of North America and adjoining islands; also Panama and the Hawaiian Islands. Papers by American writers on the geology of other parts of the world are not included. Textbooks and papers general in character by American authors are included; those by foreign authors are excluded unless they appear in American publications. As heretofore, the papers, with full title and medium of publica­ tion and explanatory note when the title is not fully self-explana­ tory, are listed under the authors, arranged in alphabetic order. The author list is followed by an index to the literature listed. In this index the entries in one alphabet are of three kinds first, sub­ ject, with various subdivisions, to enable the specialist to ascertain readily all the papers bearing on a particular subject or area; sec­ ond, titles of papers, many of them abbreviated or inverted, under their leading words; and third, cross references, which have been freely used to avoid too much repetition. The subjects have been printed in black-faced type, the titles of papers and cross references in ordinary type. As it may not be always obvious which subject headings have been adopted, an outline of those used immediately precedes the index. Miss Isabel P. Evans has given efficient assistance in the work. 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); and No. 645 (1915).
