Book excerpt: Excerpt from North American Geologic Formation Names: Bibliography, Synonymy and Distribution This work not only presents a list of formation names, and their synonymy and correlations as given by authors, but-also serves as a bibliography of the literature describing each formation. Mere men tions of occurrence were not entered, but it was intended to include descriptions of a formation which defined it either wholly or in part. It is probably true that the discrimination as to what is a sufficient description to entitle the reference to be included in this catalogue has not been of such a uniform character as it would have been if the prep aration of the catalogue had been wholly the work of one person; but it is not considered less valuable 'on this account, since all the really important descriptions are believed to have been included. No attempt has been made to indicate the synonymy or taxonomic value of any formation except as it was given by the author of the reference cited. It is intended to refer the investigator to the litera ture of any North American geologic formation name, and he must exercise his own judgment as to its value and standing as a formation name. The work of preparing this bulletin has been in progress for nearly three years. It has been interrupted from time to time by other office and field work of the-author. During the winter of 1899 - 1900 it became evident that this work must be completed at once for the use of members of the United States Geological Survey in assigning names to the formations which were being delineated on the folios forming the Geologic Atlas of the United States. The Director of the Survey requested the following geologists to assist in completing the work: Messrs. M. R. Campbell, N. H. Darton, J. S. Diller, G. H. Girty, C. W. Hayes, F. H. Knowlton, F. L. Ransome, G. O. Smith, A. C. Spencer, T. W. Stanton, J. A. Taff, T. W. Vaughan, and David White. The literature that then remained to be examined was apportioned among these gentlemen, and since that time the material has been brought down to January 1, 1901, by the author. The methods of preparing this material, previously adopted, were followed with as much uniformity as was possible, and the author, as well as geologists in general, is greatly indebted to these gentlemen who assisted in bringing the work to an early completion.
