 general interest to the farming community, to the full extent of exist- 

 ing resources. Requests for analyses of substances — as fodder 

 articles, fertilizers, etc., — coming through officers of agricultural 

 societies and farmers' clubs within the state, will receive hereafter, 

 as in the past, first attention, and in the order that the applications 

 arrive at the office of the Station. The results will be returned with-
