THE MEASUREMENT
 OF THIS TERRITORY
What the United States Geological
 Survey Is Doing.

The magnitude of the work of the L. S. Geological survey is pretty well known but 1t is doubtful if many people stop to consider what an important branch of the government that bureau is to Arizona. The following from a recent bulletin issued by the survey, sets forth the achievements of the sur vey in Arizona during the year 1905.
 A party that included Messrs. T Nj. Ramon, c. II. Birdseye. and s. :. Stahl was engaged in topogra.p .phic work in Arizona on the Desert syel}. Fort Mcdowell. Cancels Back and par of the Sacaton quadrangles for publi- cation on the scale of 1: :62.5OO, with a contour interval of 50 feet. MT R. II Sargent worked on a camp of the Tombstone Special quadrangle which
 will be published on the scale of 1:24,- GOO. with a counter interval of 50 feet.
 In order to bring the leveling of the geological survey to a higher standard of accuracy. it was decided in the fall of 1904 to adopt the coast and GeOdetic survey methods and instruments for the most important lines of levels
 With this purpose in view a precise level outfit was purchased, including
 two velocipede cars for use along the
 Southern Pacific railroad. and MT Nj 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 1901 miles ot 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 F. railroad. Between Williams and ter ome Junction the precise level was used. Early in January. 1905, Mr. 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. consisting of 92 1-2 miles. was completed and marked with iron posts. In connec- ton with the establishment of th= boundary. 10 1-2 miles of public land lines were run.
 Secondary triangulation was extend ed over three 15 minute quadrangles in MaricOpa county by MT. T. NJ Ban- non. Six secondary and three point stations were located by intersections. Owing to the exceptionally bad wealth
 er topographic work in Arizona was
 much delayed last winter.
 No geologic field work was done in
 Arizona during the last fiscal year, but Mir. Waldemar Lindgren spent consid erable time completing the Clifton fo- Iio.
 The measurement of streams in this
 territory was confined to localities in vestigated for irrigation purposes. MT. w. A. Parish was in charge of hydra graphic investigations, with headquar- ters at Phoenix, Arizona, Gauging sta
 tions were maintained at Yuma, Gila City. San Carlos, Mcdowell, Roosevelt, Alma 2nd CharlestOwn.
 The principal investigations in this
 territory were conducted by Mir Will lis 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 examined 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
