Meteorological observations in Nebraska during the year 1901, (i. D. 

 SwEZEY {Xebraska State Bd. Ae/r. Rpt. 1901, ]>p. iiOl-238). — The general characteristics 

 of the weather of each month of the year are discussed and detailed data of obser- 

 vations on temperature, precipitation, cloudiness, and direction of the wind at 159 

 places in Nebraska are given in tables. "The average atmospheric pressure for the 

 State was 30.02 in., which is 0.04 in. below the normal. . . . The mean animal tem- 

 perature for the State was 50.1°, which is 1.7° above the normal. . . . The average 

 total precipitation over the State for the year was 22.76 in., which is 0.46 in. l)elow- 

 the normal. . . . The prevailing direction of the wind was from tlie northwest.'; 

 The most remarkaljle feature of the weather of the year was the almost unbroken 

 record of high temjierature during July, "100° being recorded at some place in the 

 State on ever}' day of the month, and several stations reported 100° or over on 20 to 

 28 of the 31 days of the month."
