Present condition of topographic surveys of the United States, and new areas surveyed in 1905-6-Continued. During the season topographic surveying was carried on by 67 parties working in 26 States, namely, Alabama, Arkansas, Georgia, Illinois, Indiana, Iowa, Kentucky, Louisiana, Maine, Maryland, Michigan, Minnesota, Mississippi, Missouri, Nebraska, New Hampshire, New York, North Carolina, North Dakota, Ohio, Pennsylvania, South Carolina, Vermont, Virginia, West Virginia, and Wisconsin. The survey of 49 new quadrangles and the resurvey or revision of 11 reconnaissance sheets were completed. In addition, 60 new quadrangles were partly surveyed and 8 were partly resurveyed. The total new area mapped was 14,863 square miles, of which 3,076 square miles were for publication on the scale of 1:125,000 and 11,787 square miles were for publication on the scale of 1:62,500. There were resurveyed or revised 1,296 square miles on the publication scale of 1:125,000 and 1,883 square miles on the publication scale of 1:62,500. In connection with this work 33,590 linear miles of spirit levels of all grades were run, and 1,317 permanent bench marks were established along the routes run by precise and primary methods. Along the remainder, of secondary order, temporary bench marks were set at distances of about 1 mile. Primary control was carried on during the season by 6 parties working in portions of 19 States. They controlled 19,130 square miles lying within 77 quadrangles. Topographic surveys in eastern division from May 1, 1905, to April 30, 1906. a One square mile of the above was mapped on Kenesaw Battlefield Special, on scale of 5 inches to 1 mile, with contour interval of 10 feet. Eighty square miles were mapped on Dahlonega Special, on publication scale of 1:36,000, with contour interval of 20 feet. Included in this area are 37 square miles, embracing suburbs of Louisville, on scale of 1:24,000. d Blue Mountain Special, covering 29 square miles of this area, has been mapped on publication scale of 1:24,000. DETAILS OF TOPOGRAPHIC FIELD WORK, BY STATES. Alabama.-One party was engaged in field work in the State during the season. The resurvey of the Bessemer Special quadrangle, in Jefferson and Shelby counties, and of the Leeds quadrangle, in Jefferson, St. Clair, and Shelby counties, was completed. This work was on the publication scale of 1:62,500, with a contour interval of 20 feet. A partial resurvey was made of the Bessemer quadrangle, in Bibb, Chilton, Jefferson, and Shelby counties, which was originally intended for publication on the scale of 1:125,000, with a contour interval of 50 feet, but it has been decided to publish the results on four 15-minute sheets, with a scale of 1:62,500. In the course of this work 364 square miles were resurveyed, during which 669 miles of spirit levels were |
