AGRICULTURAL EXPERIMENT STATION. 



Wind and Rain. 



151 



The velocity of the wind has been determined by a Robinson's 

 Anemometer attached to the Experiment Station building, and the 

 amount of rain by means of a guage, signal service pattern, 

 located in the same plat as the soil thermometers.

For the full year 1890, the mean monthly velocity of wind was 

 211.16 miles, and the mean hourly velocity, 8.90 miles. The 

 rain-fall in May, 1890, amounting to 10.13 inches was larger than 

 in any other month in twenty-two years. 



Conclusion. 



This report covering simply the growing periods of two years, 

 is based upon and contains summaries of more than twenty thous- 

 and independent observations. In order to show more definitely 

 the nature and daily requirements of the meteorological work in 

 progress, I append the records for one month, selecting the month 

 of July, 1890. Their examination will disclose many points of 

 interest which cannot be incorporated into a brief report. 



By lapse of time such records and their antecedent observations 

 become increasingly valuable, and their thorough discussion, as 

 expressed in my former report, "adds to the sum of available 

 knowledge and furnishes rules for guidance useful alike for the 

 scientist and the farmer."
