Show RECONNAISSANCE IN THE UTE COUNTRY. 7 Appendix E contains meteorological record- tables of altitudes, and data for profiles of several passes. The plan of the organization of the field- party was as follows: A first civil assistant engineer in charge of the whole field- work, and who should personally do the instrumental work of the main stadia line and the astronomical work; a second civil assistant to do such work as might seem desirable; two recorders of instrumental work; one geologist, who should also, with his recorder, keep the meteorological and hypsometricai records5 a geologist's recorder; a photographer, and such rodmen, packers, and laborers as might be necessary. It was expected that enlisted men would do much of the work not requiring technical skill. On the night of April 30th, in obedience to your letter, I left Fort Leavenworth for Pueblo, accompanied by Eecorders Samuel Anstey and Donald W. Campbell. I was followed 24 hours later by Geologist F. Jlawn and Geologist Eecorder L. Hawn. The whole party arrived in Pueblo in the evening of May 5th, having been delayed 72 hours by a snow- blockade on the Kansas Pacific Eailroad. At Pueblo I was joined by Second Civil Engineer James Basstfl. We were occupied until May 7th in various preparations for the field. On the morning of May 7th we left Pueblo, beginning the line from Pueblo to Fort Garland. The longitude of Pueblo was being determined by telegraph, working in connection with Denver, and in order to determine the longitude of Fort Garland with the greatest accuracy possible to our methods, and also tofcobtain some tests of the closeness of our work, I was instructed to run, between Pueblo and Fort Garland, two entirely independent lines over the same ground. The working party was accordingly organized as follows: First Assistant Prout and Eecorder Campbell ran one instrumental line; Second Assistant Bassel and Recorder Anstey the other, and the stadia rods were carried by enlisted men from Fort Garland ; these parties were on foot. The geologist and his assistant were provided with a spring- wagon. The instruments and methods used in this portion of the survey were essentially the same as those used throughout the summer, described in Appendix A. The lines were begun at the longitude post at Pueblo, and the first meridian was taken from that of the astronomical transit used in your longitude work. The true meridian was obtained at the second and fourth camps, respectively, 18.14 miles and 46.83 miles from Pueblo, and at Fort Garland by observing with a sextant the altitude of a star at the instant when the theodolite was set upon it. At first two stars were observed, one east and one west, but owing to the practical difficulties of observing with instruments of small field, defective illumination, and no finding-circles, we soon came to rely altogether for meridians upon observations, of Polaris, his deviations being computed from known altitude or time. Two instrumental lines were run through from Pueblo to Fort Garland, entirely independent and without break, except that Mr. Bassel lost his azimuth on the first day out, and was obliged to correct his assumed azimuths from Mr. Proutfs line at the first camp. We reached Fort Garland on the afternoon of May 13th. The line run in these seven days was 85 miles, an average of 12.14 miles a day, of careful instrumental line. The longest distance run in one day was up the Sangre de Cristo, from Badito to the summit, 13\ miles. With almost no exception the country was open, and usually the only limit to the length of sights was the capacity of the instrument. Nevertheless, it was found to make these days' work on foot involved steady, smart work, and no little fatigue. Afterward we found that in open country, |
