May, 1888 — Many persons considered May very cold, yet, when we com- 

 pare the daily and monthly temperature with the former months of May, 

 I find there was less variations and extreme changes between the highest 

 and lowest temperature than any of the months mentioned. For instance, 

 May, 1887, the highest temperature was 102°; lowest, 39°; average, 63°. 1888, 

 highest, 90°; lowest, 51°; average, 69°; and yet the mean monthly temper- 

 ature of this month was less than three fourths of a degree below the aver- 

 age of the last five years. The mean temperature was 69°, maximum, 90°; 

 minimum, 51°; and the mean of the maximum was 77.1°, and of the min- 

 imum, 57.1°. Highest barometer, 30.02; lowest, 29.71; mean, 29.931. There 

 were 21 clear, 6 cloudy, and 4 fair days. Rain fell on part of 5 days and 

 a trace on 2. Rainfall for the month, .38 of an inch; season to date, 16.60. 

 Prevailing winds, southerly. No frost. At 10 p. m. on the twelfth a light 

 thunder storm passed over the town; course, from southeast to northwest; 

 precipitation .05 of an inch. Also on the thirteenth at 4:30 p. m. ; course, 

 from east to west; rainfall, .05 of an inch.
