From letter of transmittal: The report contains 63 contributions from 37 members of the Survey who have been engaged more or less continuously throughout the year in economic work, together with brief statements by the geologists in charge of the section of metalliferous ores and the section of nonmetalliferous economic minerals, of the extent and character of the economic work being carried on in the Survey.
From introduction: The aim of this paper is to present the substance of what is known concerning the distribution, occurrence, and development of the oil and gas of the quadrangle, and to note briefly the more important industries growing out of these natural resources or depending on them within the territory considered.
From letter of transmittal: This manuscript is based on geologic and topographic reconnaissance survey, made during the summer of 1903, of an important placer-gold district in the northeastern part of Seward Peninsula.
From letter of transmittal: This report contains the economic results of a reconnaissance of these gold fields of the Yukon basin which was carried out in 1903.
From letter of transmittal: It is believed that this report will stimulate the mining industry by making available, in compact form, the accumulated results of the experience of mining men in this field and by directing attention to those mining methods developed in older districts which appear to be adapted to the conditions prevailing in Alaska.
From introduction: The aim of the present paper is to put on record such observations relating to the general geology of the region traversed as it is thought may be of interest, more particularly to the people of Idaho and Oregon, and also in certain instances serve to supplement the report referred to on artesian conditions.
From introduction: This report is made in response to a general demand for information a reconnaissance of the petroleum and coal fields in the vicinity of Controller Bay and Bering River and of the petroleum fields on the west shore of Cook Inlet and at Cold Bay made during 1903 and 1904.
From letter of transmittal: The report contains fourteen papers, prepared by ten members of the geologic corps, who have been engaged in Alaskan investigations during the last year. In this report an attempt has been made to summarize the economic results of last season's field work. Geologic matter has been entirely excluded, except where it has a direct bearing on the subjects under discussion. While such a report can have no permanent value, other than as a record of mining conditions during the year, it is believed that its prompt publication will help the mining industry of Alaska.
From introduction: This report contains papers on summaries of progress in various phases of the mining industry during the last year, preliminary accounts of investigations in progress or completed, and statements of the results of minor investigations not to be published elsewhere.
From introduction: From introduction: The present report upon the work of this field season is accompanied by topographic and geologic maps of the vicinity of Juneau, and of a mainland strip extending approximately 200 miles along the coast.
From introduction: This report contains the results of the primary triangulation and primary traverse executed by the USGS during the fiscal year 1902-3.
From introduction: This report contains the results of primary triangulation and primary traverse in the eastern and western divisions of the United States.
From introduction: It is the purpose of this bulletin to combine the results obtained by the USGS parties that have visited the region, together with the information derived from a study of specimens of tin ores and associated minerals recently brought from the York region by outside parties.
From preface: In planning the surveys and investigations of Alaska, the attempt was made to cover first those regions which were of the greatest economic importance.
From introduction: The subject of this paper is the district of the extreme northwestern portion of Illinois, included in the upper Mississippi Valley containing zinc and lead.
