At a meeting of the State Board of Agriculture held in Lansing, Dec. 1, 

 1885, the undersigned was appointed the agent of the Board to make the 

 analyses of commercial manures contemplated in the foregoing act. The 

 object of the law is to protect the purchasers and honest manufacturers, 

 and to prevent or to punish fraud in commercial fertilizers. 



The specimen for comparison of any fertilizer, with affidavit, and the fee 

 for analysis, must be deposited with the secretary of the Board on or before 

 the first day of May each year. 



Any manufacturer or importer who desires to avail himself of the benefits 

 of the proviso in Sec. 3, should notify me of the names of agents selling the 

 fertilizers in this State, and the place where they are offered for sale. 



Specimens for analysis will be selected in the open market, and not 

 received from the manufacturer or his agent. 



For the sake of uniformity in the certificate required in Sees. 1 and 2 to
