Show 8 Time- signals were transmitted free of charge over the wires of the Western Union Telegraph Company from Las Vegas and Cimarron, N. Mex., and over those of the Atlantic . and Pacific Telegraph Company from the other localities upon the Union Pacific Eailroad. The results of the observations taken at Julesburg, near the station ou the Union Pacific Eailroad, and on the southern side of the railroad-track, show this point to be south of the forty- first parallel of north latitude, or in Colorado instead of Nebraska, as it has heretofore been shown upon some of the published Government maps. The situation of the station in relation to the Union Pacific Railroad and boundary is shown below. J^ LHl; Kansas lG187Miles. O L O R A D O The usual meteorological observations have been kept up by the party operating at these points. A comparison of times was had between the survey observatory at Ogden, and United States Naval Observatory at Washington, D. C, by Assistant John H. Clark, and Prof. James K. Eastman, United States Navy. The necessary sets of observations for a determination of the difference in longitude were made, and thus a third comparative result for the longitude of the east pier in the west obseiving- room at the Ogden observatory has been obtained; those previous having been by connection with the United States lake survey at Detroit, Mich., and with the pier establised by the United States Coast Survey in the Mormon Temple grounds in Salt Lake City, Utah. Another set of observations was also taken to serve as a comparison with the latitude previously obtained for the position of the instrument upon this pier. In addition to the positions above given, the astronomical station occupied by Lieut. E. H. ltuffuer, Corps of Engineers, at South Ptfeblo, Colo., in 1873, and of which no latitude had been published, was rebuilt, and a set of zenith- telescope observations made thereat. The report, with result, is herewith. PUEBLO, COLO. Longitude: 104^ 36' 57" Latitude: ,53. 3Soi5' 42". 84± 0" 17. The station is situated on the top of the bluff near the railroad- station in South Pueblo. The instrument was the same used at the previous stations of Las Vegas and Cimarron, N. Mex. The longitude as given above is derived from geodetic work, in connection with our primary astronomical stations at Labran, Colorado Springs, and Trinidad, Colo., executed in the seasons of 1873- 74. |
