to precipitation than the atmosphere in general, and it confers on the eastern 
shore of the lake a climate of exceptional humidity. 
The character of this climate is clearly indicated by the assemblage of 
the observed facts in regard to precipitation. Through the kindness of 
Prof. Joseph Henry I have been permitted to examine the rain records 
accumulated by the Smithsonian Institution, including not only those which 
have been embodied in the published “Tables,” but the more recent data 
to be included in the forthcoming second edition. The following table 
shows the mean annual precipitation for all stations in Utah, Nevada, 
Wyoming, and Colorado, which have a record two years or more in extent, 
together with certain other facts for comparison. The temperature means 
are taken from the Smithsonian Temperature Tables and the United States 
Signal Service Reports.
