nent bench marks and 1,256 elevations were determined; and 692 miles of road traverse were run.

Minnesota.-One party was engaged in completing the survey of the Lake Minnetonka quadrangle, in Carver, Hennepin, and Scott counties, for publication on the scale of 1:62,500, with a contour interval of 20 feet. There were mapped 224 square miles within the quadrangle, and in addition 12 square miles beyond the quadrangle limits. There were 592 miles of spirit levels run, in the course of which 24 permanent bench marks and 4,794 elevations were determined, and 797 linear miles of road traverse were run.

Mississippi.-One party was engaged in the field during the fall on the survey of the Jackson quadrangle, in Hinds, Madison, and Rankin counties, which was completed. A partial survey was made of the Florence quadrangle, in Copiah, Hinds, Rankin, and Simpson counties, and of the Raymond quadrangle, in Hinds and Madison counties. This work is for publication on the scale of 1:62,500, with a contour interval of 20 feet. There were 404 square miles of the State's area mapped. Spirit levels to the extent of 355 miles were run, in the course of which 21 permanent bench marks and 1,523 elevations were determined, and 284 linear miles of road traverse were run.

Missouri.-Two parties were engaged in field work in the State during the season. The survey of the Nebraska City (Nebraska-IowaMissouri) quadrangle, in Atchison County, was completed, and partial surveys were made of the following quadrangles: Forsyth, in Christian, Stone, and Taney counties; Atlanta, in Knox, Macon, and Shelby counties; Macon, in Macon, Monroe, Randolph, and Shelby counties; Shelbina, in Monroe and Shelby counties, and Shelbyville, in Knox and Shelby counties. The above work is for publication on the scale of 1:62,500, with a contour interval of 20 feet, except the Forsyth, which is for publication on the scale of 1: 125,000, with a contour interval of 50 feet. In the course of these surveys 932 square miles were mapped; 98 trigonometric points were located; 1,324 miles of spirit levels were run, in the course of which 56 permanent bench marks and 5,457 elevations were established, and 4,190 linear miles of road trayerse were run. Besides the foregoing, the revision of 4 square miles of the De Soto quadrangle, with 82 miles of road traverse, was accomplished, and an addition of 45 miles of spirit levels, with 15 permanent bench marks and 200 elevations, was made.

Nebraska.-One party was engaged in field work in the State in the fall. The survey of the Nebraska City (Nebraska-Iowa-Missouri) quadrangle was completed in Nemaha and Otoe counties, for publication on the scale of 1:62,500, with a contour interval of 20 feet. This work resulted in the mapping of 200 square miles. There were run 290 miles of levels, in the course of which 18 permanent bench marks
