Twenty-Second Annual Report of the Director of the United States Geological Survey, 1900-1901: Part I - Director's report and a paper on asphalt and bituminous rock deposits
The work of the Geological Survey during the fiscal year 1900-01 was mainly a continuation of that of previous years, described in former reports. The organization was changed somewhat (see p. 48), but in a general way similar results were reached, which added materially to the sum of geologic and geographic knowledge. The detailed record of accomplishment, both in field and in office, will be found on later pages, under the heading " Work of the year" (p. 53). In this introduction some subjects of special interest will receive consideration.
