Mohave County miner., 1906-02-24
Arizona.


 A party that included Messrs. T. M. Bannon, c. H. Birdseye, and s. s. Stahl, was engaged in the topographic work in Arizona on the Desert Well, Fort Mcdowell, Camels Back, and part of the Sacaton quadrangles, for publi- cation on the scale of 1:62,5OO, with contour interval of 50 feet. Mr. R. H. Sargent worked on map of the Tomb stone Special quadrangle, which will be published on the scale of 1:24,0O0 with a contour interval of 50 feet.
 In order to bring the leveling of the Geological Survey to higher stand ard of accuracy, it was decided in the fall of 1901 to adopt the Coast and Geodetic Survey methods and instru- ments for the most important lines of levels. With this purpose in view, a precise level outfit was purchased, in- cluding two velocipede cars for use along the Southern Pacific railroad, and Mir. M. s. Bright, levelman, ran the first line from Yuma to Tucson.
 In all, the Geological Survey map ped 7S7 square miles in Arizona, ran 2S3 miles of spirit levels and l60l miles of traverse lines, and established 9l bench marks.
 Topographic surveys of forest re- serves in this state were also made, including work on the Shinumo quad rangle. To secure additional control for this quadrangle and adjacent areas a line of levels was run from Apex Sid ing to Williams, along the Grand Can yon railroad, and by way of Ash Fork to Jerome Junction along the Santa Fe railroad. Between Williams and Jerome Junction the precise level was used. Early in January, 1905, MT. John P. Walker, United States sur veyor, began to survey the boundary of the Chiricahua Reserve. He con tinued the work until the early part of May, when the entire line, consist ing of 92 l-2 miles, was completed and marked with iron posts. In connection with the establishment of the boun- diary, 10 l-2 miles of public land lines were run.
 Secondary triangulation was extend ed over. three 15-minute quadrangles in Maricopa county by Mir. T. M. Ban non. Six secondary and three point stations were located by intersections. Owing to the exceptionally bad wealth CT, topographic work in Arizona was much delayed last winter.
 No geologic field work was done in Arizona during the last fiscal year, but MT. Waldemar Lindgren spent considerable time completing the Cliff ton folio.
 The measurement of streams in this territory was confined to localities in- vestigated for irrigation purposes. Mr. w. A. Parish was in charge of hydro graphic investigations, with head quarters at Phenix, Ariz. Gazing sta- tions were maintained at Yuma, Gila City, San Carlos, Mcdowell, Roose- welt, Alma, and Charlestown.
 The principal investigations in this Territory was conducted by MT. Willis T. Lee, in the valley of Colorado river, from the mouth of the Grand Canyon to Yuma. Most of the valleys and mountain ranges in this area were eX- amined and a report was prepared and submitted for publication. Prog ress was also made with the prepara- tion of the report on the underground waters of the high plateau area of the northern-central and northeastern DOT tions of the Territory. A paper on the underground waters of Gila Valley by Mr. Lee was published and one on the underground waters of the Salt River
