good, about 80 per cent of the crop showed the rows across the field, and 

 cultivation was making good progress in the drier counties. The cold, 

 cloudy, rainy weather of the first week prevented proper pollination of 

 cherries and plums thereby greatly reducing the crop. Pastures, clover, 

 timothy and alfalfa are in the best condition for several years, except 

 where injured beyond recovei-y by drouth and grasshoppers in the south- 

 west portion last season. Winter wheat made rapid growth and be- 

 came so rank generally as to be subject to damage by lodging.
