Cooperative Topographic Survey of New York. DEPARTMENT OF THE INTERIOR, UNITED STATES GEOLOGICAL SURVEY, WASHINGTON. March 21, 1911. Hon. J. A. BENSEL, State Engineer and Surveyor, Albany, N. Y.: Dear Sir. In reply to your letter of March 15: I have the honor to make the following report of the results of the cooperative topographic survey of New York from January 1 to December 31, 1910: Allotments. The agreement signed by the Director of the United States Geological Survey on June 25, 1910, and by the State Engineer and Surveyor of New York on June 28, 1910, provided for the continuation of the coöperative topographic survey of the state and for the expenditure of $10,000 by each of the contracting parties during the Federal fiscal year ending June 30, 1911. Of the sum provided for coöperative surveys during the preceding fiscal year there remained on May 1, the beginning of the field season of 1910, $3,551.78, making the total sum available to June 30, 1911, $23,551.78. Of this sum there had been expended on January 1, 1911, $18,444.55, leaving a balance on the part of New York State. of $1,599.66 and on the part of the United States Geological Survey of $3,507.57, a total balance of $5,107.23, to be expended for the payment of office salaries involved in the drafting of maps and for the preliminary field work of the season of 1911. Results. The coöperative topographic survey of New York was continued under the immediate supervisory charge of Mr. Frank Sutton, geographer in charge of the Atlantic Division, the general charge of all such work of the United States Geological Survey being under Mr. R. B. Marshall, chief geographer. During the season of 1910 surveys were made in St. Lawrence, Delaware, Jefferson, Otsego, Chenango, Herkimer, Oneida and Lewis counties, and resulted in the completion of the Hartwick and Hammond quadrangles, the complete survey of the Canton, New Berlin and McKeever quadrangles and the partial survey of the Lowville quadrangle. Preliminary work was started on the Number Four quadrangle. The total area mapped during the season was 831 square miles, for publication on the scale of 162,500, with a contour interval of 20 feet. For the control of the above areas, 236 miles of primary levels and 914 miles of secondary levels were run, in connection with which 48 permanent and 197 temporary bench-marks were established. In addition, 84 miles of primary traverse and 1,491 miles of secondary traverse were run, in connection with which 667 traverse stations were located and 11 were permanently marked. Progress to Date. Prior to the season of 1910-11 there had been surveyed and mapped 215 quadrangles and two quadrangles had been partially surveyed. At the conclusion of the field season of 1910-11, therefore, 220 atlas sheets of New York state had been completed and one partially completed, representing the topography of 40,870 square miles. The total area of the state is 49,204 square miles, thus leaving 8,334 square miles yet to be mapped. Field Work in 1910. Field work was commenced in May by Mr. C. E. Cooke, topographer, and Mr. J. M. Whitman, assistant topographer, and later by R. C. McKinney, topographer, Messrs. J. I. Gayetty and S. P. Floore, assistant topographers, and Mr. J. H. Lee Feaver, junior topographer, who completed the survey of the quadrangles named. Primary traverse control work was done by Mr. D. H. Baldwin, topographer, and primary leveling by Mr. C. H. Semper, assistant topographer. Office Work. The final drawings of the Hartwick, Hammond, Canton, New Berlin, and McKeever topographic sheets will be completed during the spring and will then be transmitted to the engraving division for publication. These, with the Antwerp, Delhi, Monticello and Neversink topographic sheets, for which advance photolithographic sheets have already been issued, are the only atlas sheets completed in New York that have not been engraved. The Bath and Stony Creek atlas sheets were published during 1910. Very respectfully, H. C. RIZER, Acting Director. |
