used for fertilizing purposes the price of which exceeds $10 

 per ton, and to lime, marl and wood ashes intended for fertil- 

 izing purposes at whatever price they are sold. 



For many years the sale of materials other than mixed goods 

 was so small that no notice was taken of it. As time went on, 

 however, with the propagation of the ideas of home mixing, 

 the demand for chemicals increased. For the last few years 

 the most common chemicals such as acid phosphate, ground 

 bone, nitrate of soda and the various potash salts are regularly 

 registered by the companies handling them. In the case chiefly 

 of companies manufacturing in the State it happens that other 

 fertilizing constituents are sold in small amounts and primarily 

 for experimental purposes. While the law is explicit there will 

 until further notice, be no prosecutions made by the Commis- 

 sioner of Agriculture for the sale without registration of small 

 amounts of these more unusual fertilizing constituents, pro- 

 vided the company can show that these goods were sold in 

 good faith for experimental purposes. As a part of the indi- 

 cation that the goods were thus sold it should be explained to 

 the customer exactly under what conditions the goods are sold; 

 that they are unregistered ; that they have not been or are not 

 likely to be analyzed by the Director of the Maine Experiment 

 Station and that the Commissioner of Agriculture holds himself 

 in no way responsible for the quality of these unlicensed goods 

 sold for experimental purposes. Their sale is allowed because 

 the Commissioner of Agriculture does not regard it as the 

 purposes of the law to either hamper ordinary business or 

 hinder experiments on the part of the farmer. Whenever any 

 goods thus offered experimentally come to be sold in consid- 

 erable amount they must be registered the same as other fer- 

 tilizing materials.
