32 EXPERIMENT STATION EECOED. 



"The meteorological conditions prevailing flaring the year 1895 present several 

 features of unusual interest. The Aviuter months were excei)tionally severe, and 

 minimum temperatures occurred in the mountainous sections of the State lower than 

 any previously recorded. The mean temjierature for February is the lowest for any 

 month of any year since 1872, excepting only January, 1893, which was 1.9 degrees 

 colder. 



"During the summer there were two periods of iinusual heat, one extending from 

 May 29 to June G; the other from September 18 to September 26, during both of 

 which maximum temperatures (above 100 at many places) occurred, breaking all 

 previous records at those seasons of the year. Nevertheless, the cold of winter kept 

 the annual mean temperature for the State below the normal. 



"Following a period of excess of rainfixll (March, April, May), the 7 months from 

 June to December were notable for the continued prevalence of droughty conditions, 

 all 7 months being below the normal in rainfall, and September particularly so. 

 Yet the annual deficiency was not very great. Since 1872 there have been 7 years 

 with a less annual total of rainfall than 1895 ; while this year there were no months 

 so dry as December, 1889, November, 1890, and October, 1892. There has probably 

 never before occurred so extended a period of deficiency in precipitation." 



Meteorological observations in Wyoming, 1891-'96, J. D. Con- 

 ley ( Wyoming Sta. Bui. ^7, ])P- ^^)- — General notes are given on the 

 weather of Wyoming, and on the character and history of the meteor- 

 ological observations made by the station since 1891, with descriptions 

 of apparatns and summaries of observations at the station at Laramie, 

 and at the substations at Lander, Saratoga, Sheridan, Sundance, and 

 Wheatland.
