PACIFIC SECTION OF TOPOGRAPHY. 
In this section, under the direction of Mr. Richard IT. Goode, geog- 
rapher in charge, spirit leveling was continued for the control of the 
regular topographic work executed during the year in the various 
localities, as follows: 
IDAHO-MONTANA. 
SHOSHONE AND MISSOULA COUNTIES.. 
Cceur D'Alene Mining Reg-ion. 
The elevations in the following list are in continuation of leveling 
reported upon in the Appendix to the Twenty-first Annual, and are 
based on an aluminum tablet in the top of the latitude pier in the 
grounds of the county court-house at Spokane, Wash., accepted as 
1,890.954 feet above mean sea level. These elevations depend 
directly upon that of a bench mark at Lane, Idaho, as published on 
page 522 of that Appendix. 
The leveling was done, under the direction of Mr. Van II. Manning, 
topographer, by Mr. F. E. Washburn, levelman. 
All bench marks depending on this datum are stamped with the 
letter "S" in addition to the figures of elevation.
