Il8 MAINE AGRICULTURAL EXPERIMENT STATION. I912. 



exposing for sale, distribution or transportation, any materials 

 used for fertilizing purposes the price of which exceeds $10 

 per ton. 



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 

 licensed 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 Director of 

 the Maine Agricultural Experiment Station for the sale with- 

 out license of small amounts of these more unusual fertilizing 

 constituents, provided the company can show that these goods 

 were sold in good faith for experimental purposes. As a part 

 of the indication that the goods were thus sold it should be 

 explained to the customer exactly under what conditions the 

 goods are sold; that they are unlicensed; that they have not 

 been or are not likely to be analyzed by the Director of the 

 Maine Experiment Station and that the Director holds himself 

 in no way responsible for the quality of these unlicensed goods 

 sold for experimental purposes. Their sale is allowed because 

 the Director 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 ofTered experi- 

 mentally come to be sold in considerable amount they must be 

 licensed the same as other fertilizing materials.
