 ings, field crops, etc., and assisted in the work of cow-testing and 

 bull associations, and in work with fairs.

 plants, with particular attention to the sanitary condition of the 

 factory, quality of packing stock, manufacturing processes, and 

 moisture content of the finished product. The output was 4,003,403 

 pounds, a decline of more than 25 per cent from the preceding year.
