Amount ov Sunshine. 

 The amount of sunshine as an essential factor in crop produc- 

 tion is worthy of observation and record. Observations were 

 commenced May 1, 1890, and the table below furnishes the sum- 

 mary for the six months following and for seven months, April to 

 November, 1891.

During the period covered by the above table, the average hours 

 of bright sunshine per day were G.3 or 46 per cent, of the possible 

 amount. 



"Wind and Rain. 



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

 Anemometer, with electrical recording apparatus, attached to the 

 Experiment Station building, and the amount of rain by means of 

 a gauge, signal service pattern, located in the same plat as the 

 soil thermometers.
