Meteorological Report for 1888. 



The following meteorological report for the year 1888 was compiled for 

 the "Republic," by J. E. Lewis, Signal Service Agent at this city. The 

 record is from January 1 to December 31, 1888: 



Number of clear days, 221; number of cloudy days, 117; number of fair 

 days, 28. Highest temperature, 96°; lowest temperature, 27°. Greatest 

 velocity of wind, 32 miles per hour. Number of days in which .01 of an 

 inch or more of rain fell, 42; amount of rain in year, 11.38 inches; amount 

 for season of 1887-88, 18.33 inches. Highest barometer, 30.098; lowest 

 barometer, 26.251. 



The rainfall for the season was not as favorable for vegetation as its 

 quantity would indicate, from the fact that heavy rains fell in September 

 and October, 1887, which were of no benefit whatever. There were but 

 very light rains after January. 



During January the weather was colder than ever before recorded in this 

 section, the record of lowest self-registering thermometer being 27°, and 

 numerous outdoor water pipes were frozen and bursted, an unprecedented 

 occurrence. The highest thermometer was 96°, in October.
