(8.) INSTRUMENTAL VALUES. 



The values of the implements pertaining to zenith-instrument No. 28 are, for one 

 division of the micrometer-screw, o".622; of the striding-level A, i".2i; and of the 

 zenith-level, i". 10. The wire which made the circuit between the stations Salt Lake 

 and Cheyenne, counting the distance along the railroad, is some 550 miles, and does 

 not include any battery or repeating-office. At Cheyenne there was a repeating-office ; 

 but as the observatory, as elsewhere stated, was situated west of it, the signals did not 

 work through any repeater; and at the time these observations were made Salt Lake 

 itself was only a relay-office ; but there was a switch at Ogden, which had always to be 

 called to "straighten" the wire before the work of exchanging could be commenced. 

 Powerful batteries have always been kept at both places, and lately the repeating-office 

 at Corinne has been removed to Salt Lake, and the latter has not only become a re- 

 peating-office but also the headquarters of the western division of the main or eastern 

 branch of the company.
