From June 1 to the midrtle of Sppti-iiiljer the aver.itjc soil moisture was several per 

 cent less than that of the same soil at tlic same period laSt year. The dronth this 

 year was very considerable, as is shown by the weekly crop rejiorts presented in a 

 later table. As in 1889, the percentages of nioistnro were mnch lower than those of 

 1888. As last winter was also an open one, it still remains to be seen whether the 

 difference in the absorptive power and rctentivencss of the soil for moisture pro- 

 duced by the freezing of a severe winter, is sutiicient to explain the observed varia- 

 tion.
