LETTER OF TRANSMITTAL.
Unirep Srates ENGINEER OFFICE, GrocrapHicaL Surveys West or THE 100TH MERIDIAN, Washington, D. C., March 1%, 1877.
Grnera: I have the honor to submit herewith, for publication, the reports to constitute Volume II of those authorized by acts of Congress, approved June 23, 1874, and February 15, 1875.
The volume consists of the several reports upon determinations at main astronomical stations, with lists of geographical positions and altitudes of prominent points, together with results from the barometric work.
The necessity for astronomical determinations at points in the western interior, contiguous to the fields of survey, became apparent at an early stage of the work, since the principal longitudes in the region occupied were necessarily approximate for want of telegraphic communication, and other essentials of accuracy. The latitude determinations have been found to possess a much greater degree of accuracy, and are the only ones which could be relied upon, except an extremely limited number of longitudes. It is believed that the methods adopted for the observations and their com- putation have proven adequate for the requirements of standard field astronomical work, and the results are so grouped as to show in each case their greater or lesser probable values. The importance of these astro- nomical determinations with stations and meridian lines usually marked with permanent monuments in the prosecution of extended geographical surveys cannot be overestimated. In regions remote from railroad com- munication, more portable instruments and different methods, similar to
those adopted in 1869, can be used with efficiency. xI
XII LETTER OF TRANSMITTAL.
Prior to the establishment of a survey covering the entire interior of the country, it is not presumable that more elaborate means will be used for the fixing of geographical positions, so necessary in the construction of detailed topographical maps, since the cost of the establishment, in the rough mountain interior, of geodetic points of the highest order of accuracy is not justified by the uses to which they may be applied in the present development of connected surveys of this region. When topographical results are acknowledged as a want more frequent and wide-spread, a great geodetic survey of the entire territory of the United States may be begun; meanwhile, the geodesy of the mountains as it is now conducted, demanding primarily the determination of initial points at which measured and devel- oped bases and subsequent schemes of triangulation may be laid out, such as shall meet present requirements, must be confined to such as are needed more particularly for mapping purposes, and for such geodetic points as may be required by the surveys of the public lands.
The observatory at Ogden, Utah, remains incomplete, but the impor- tance of it, and such others as have been recommended to be established, suggests mention.
This volume will be found not without value to the future compiler, because of the geographical positions and altitudes that it contains, and serves to show the operations and results in this section up to the close of the season of 1874.
Lieut. William L. Marshall, Corps of Engineers, in charge of the baro- metric reductions from December 1, 1874, to August 8, 1876, submits the results of the labors of this section that had been previously carried on under the direction of Lieut. R. L. Hoxie, Corps of Engineers, after the plan of organization as laid down by the officer in charge.
It was at one time contemplated to extend the scope of the hourly observations so that the results would have been more widely distributed, but the additional force required in observations for altitude determinations and the temporary cessation of the annual occupancy of main astronomical stations, have led to their abandonment in other than exceptional cases. His report is a summary of the barometric and hypsometric observations, and
results to date; other than those submitted in the regular annual reports.
LETTER OF TRANSMITTAL. XI
The methods followed in the reduction of the barometric observations for altitudes have, with some slight modification in case of the aneroid readings, been those given in the invaluable treatise upon this subject by Lieut. Col. R. 8. Williamson, Corps of Engineers, and forming Professional Paper No. 15, of the Engineer Department, United States Army.
The gradual and constant improvement in this section of the survey has been noticeable and merits approval. I take this occasion to signify appreciation of the great industry, often exhibited under the most trying circumstances, of the astronomical and meteorological observers, most of whose names appear in the several reports, while the results as shown are, in a measure, the test’ of their success.
All of which is respectfully submitted.

Ogden is a Mormon town of nearly 2,000 inhabitants, the junction of the Union Pacific and Central Pacific Railroads. The astronomical station is situated on a low hill west of the town, near the Utah Central Railroad, about 2,000 feet from the Weber River, which flows by in a southerly direction; the niveau of the stream being about 100 feet below the flecr of the observatory.
DESCRIPTION OF OBSERVATORY.
The foundation of this building is of granite and sandstone, and rises 34 feet above the ground, inclosing a cellar, which has a depth of 4 feet from the floor. The structure consists of three parts: the eastern wing, which is intended for the use of the officer in charge; the western wing, occupied as an observing transit room; and the center, which will contain a solid pyramidal pier to support an equatorial. The dimensions of the two wings are the same, being 11 feet by 15 feet on the ground and 94 feet in height. The central compartment is 15 feet square, and will have two floors. The eastern room is lighted by six windows, each 2¢ feet by 63 feet, which, in size and position, are similar to the apertures which are cut into the western wing for purposes of meridional observation. The latter openings extend to the top of the wall and thence across the roof, and are
closed by vertical shutters upon the side of the building and a horizontal 7

pair upon the top, by which the interior is sheltered from the dust and rain. The observing room contains two piers of solid sandstone, which are planted 6 feet below the floor, and protrude 2 feet above the same. A third pier, which is of brick-work, insulated, and intended to carry a clock, has been erected in the southeastern corner of the observing room. Chronographic and telegraphic apparatus are placed on separate stands. The whole building is covered with a heavy tin roof.
CONNECTIONS—-OBSERVERS—METHODS.
The longitude of Ogden observatory was determined in three different ways: first, Ogden was connected with Salt Lake City observatory in 1873, by Dr. F. Kampf and Mr. John H. Clark, observers; second, Detroit was connected with Ogden in 1873 by Mr. O. B. Wheeler, assistant in the United States Lake Survey, and Dr. F. Kampf, observers; and, third, the United States Naval Observatory at Washington, D.C., was connected with Ogden in 1874, by Prof. J. R. Eastman, of the Naval Observatory, and Mr. John H. Clark, observers. In all cases, observations were recorded at both places by means of the chronograph, and the longitude was deter- mined by automatic signals of the chronometer, as well as by arbitrary breaks on the chronograph.
In reference to the first determination, it should be stated that each observer reduced his own observations, after leaving the field, by means of the method of least squares.
A description of the second determination will be found in the report of the Chief of Engineers for 1874, page 434 et seg. The observations taken at Detroit have been computed in a different way from those made at Ogden, and have afterward been recomputed by the method employed in this office. The result thereby attained is taken for the comparison of the final results.
The last determination, which was obtained in 1874 by a direct con- nection with Washington, is based upon the computations made by Professor Eastman and those of Dr. F. Kampf, who reduced the corresponding Ogden observations.
OBSERVATORY STATION—OGDEN, UTAH—1873~74. g) INSTRUMENTS—TELEGRAPHIC COMMUNICATION.
In the season of 1873, the Wiirdemann combined transit-instrument No. 28 was used. This had been previously employed in the determination of Colorado Springs, and is described, with its values, in the report on that station, published in 1874. In 1874, observations for latitude were made with the same instrument, but the time observations were taken with the 32-inch astronomical transit Wiirdemann No. 29.
All telegraphic signals were transmitted over the wires of the Western Union Company. The length of cireuit from Ogden to Salt Lake was 37 miles; from Ogden to Detroit, 1,800 miles; and from Ogden to Washington, 2,365 miles. Signals were dispatched in 1873 by means of a battery of three Grove’s cells, belonging to the Survey; in 1874, a Hill battery of two cells was used. On the eastern routes, there were repeaters at. Cheyenne, Omaha, Chicago, Pittsburgh, and Harrisburgh.

GEOGRAPHICAL POSITION OF STATION.
Longitude, . .... . . 1129388! 35’.90 + 0.26 west from Greenwich. 35° 35! 34/’.10 west from U.S. Naval Observ- atory, Washington, D. C. uatitude, - . . .. =. « . 38°16! 23.25 + 0.06 north. Barometric altitude of observatory above sea-level, 5915.6 feet.
This station was situated in the main plaza of the town, a short distance east of the church, which is used by religious societies other than the Mormon, and between this building and the main street running from north to south. The town of Beaver is laid out on a bench or tongue of land which inclines to the south, and is bounded by North Creek and the dry - bed of Beaver Creek, whose water is turned from its course for purposes of irrigation before it reaches the settlement. Directly northward, no mount- ains are visible; in that direction, however, the valley, if such it may be called, is much broken. On the west is a chain of mountains which has the same general direction as the Beaver Range on the east. In the south, the broken character of the general country is fully maintained.
METEOROLOGICAL CONDITIONS.
While at Beaver, a succession of storms, which, preceded by heavy winds, commenced about the middle of August, came up from the south, sometimes bringing torrents of rain, and interfering much with the astro- nomical operations. By the time any given storm had passed beyond Beaver, leaving weather fit for observations, it had reached Salt Lake City, interrupting the observer there, so that, out of 21 nights, there were only 10 that could be used in common for time and signal exchanges. Obser- vations for clock-error were made on August 10, 11, 12, 13, 14, 15, 16, and September 2, 3, 4, 5, 6, 7, and it took all of that time to succeed in making three exchanges. The nights of August 18, 19, 20, 21, 23, 24, 25, 27, 30, were given to the determination of latitude; on a majority of these, there were only partial observations, in consequence of interruption from rain and

OBSERVATORY—PARTY—TELEGRAPH.
A simple wall-tent constituted the observatory. John H. Clark was principal astronomical observer, and was assisted by W. W. Marryatt. An hourly meteorological record was kept by F. R. Simonton and C. Herbert. The telegraph-line employed was the Deseret of Utah. ‘The operator was Robert, son of Bishop Farthingham, of the Mormon Church.
INSTRUMENTS.
The observations were made with the zenith meridian instrument, Wiirdemann, No. 16. Its focal length was 26 inches; its aperture, 1} inches. It was mounted on a block of wood 7 feet in length, which was planted in the ground to a depth of 4 feet. The Negus chronometer No. 1499 was used.
CONNECTIONS—COMPUTERS
The longitude was obtained by the exchange of arbitrary signals with Brigham Young’s observatory at Salt Lake City, where E. P. Austin was observer. These exchanges, which were received and sent by sound, were made on three different nights. They consisted of 42 signals in a series, 21 being transmitted each way every night. The observations for longi- tude were computed by John H. Clark and Dr. F. Kampf; those for latitude were reduced by Wm. A. Rogers and by Dr. Kampf.
INSTRUMENTAL VALUES.
One division of the striding-level had the value of 1.14. For each division of the zenith-telescope level there was a value of 1’.44. One revolution of the zenith-micrometer was equal to 81.00. The telegraphic circuit was upward of 200 miles in length. There was a battery at Beaver where the line branched. There was no attempt to use a register or chro- nograph here, and the signals were obtained by taking the chronometer to the telegraph office.

GEOGRAPHICAL POSITION OF STATION.
Longitude, . . . . . . - 114° 2618.27 4 1.12 west from Greenwich. 37° 23! 16.47 west from U.S. Naval Observ- tory at Washington, D. C. Matituder: 9. a <j) ns 800.50! 26.07 = 0.07 north.
Barometric altitude of observatory above sea-level, 5942.3 feet.
The astronomical station is 120 feet to the left of the road leading from Pioche to Bullionville. Its distance from the church on the corner of Cedar and Meadow Valley streets is 3,050 feet in a line whose direction is south- west by west. About 1,250 feet from this church, on the summit of the divide, where it is crossed by Meadow Valley street, and near the Gold Hill Mine, there stands a very conspicuous telegraph-pole; the astronomical mouument is situated 1,060 feet south and 1,470 feet east of this.
The city lies on the northeastern declivity of hills which form a spur of the Ely Mountains. The surrounding country slopes gradually down to the plains in the same direction.
OBSERVATORY—INSTRUMENTS—MISCELLANEOUS.
A description of the instruments used, with the values pertaining to them, will be found in the report on Beaver, which precedes this. Much general information on this station, including a description of the observatory and methods of observation, is given by Mr. Maryatt, on page 46 of the Progress Report of 1872.
This was the first of the series of stations occupied in 1872 by the late Wm. W. Maryatt, who died in 1873, at Bozeman, Montana. This gentleman took the greatest care to secure results as satisfactory as possible, as will
be seen from the observations made. 75
