Meridian-Projecting Instruments And Methods, Albert Babbitt Bartlett
Meridian-Projecting Instruments And Methods, Albert Babbitt Bartlett
Bachelors Theses
"The writer's attention was called to the necessity of knowing the accuracy attainable in surveying which must depend upon the Meridian, and therefore be subject to the accuracy of it, in seeking information by which to decide what would be the most desirable transit to use in the West, particularly for United States Deputy Mineral Surveying. Descriptions of the manipulation, adjustments, and the cost, etc., of the various appliances are plentiful in the text-books on surveying and in the various catalogues; but there was no very definite information in regard to the actual probable and average accuracy, especially in the …

Efficiency Of Mill Practice In The Joplin District, Ira Lee Wright
Efficiency Of Mill Practice In The Joplin District, Ira Lee Wright
Bachelors Theses
"Milling in the Joplin District is, compared with the practice in other zinc fields, seemingly very crude. To one unacquainted with the peculiar conditions of this district, the amount of ore which goes into the tailing pile seems unnecessarily high. There are several things which account for the low saving made"--page 1.
