large warehouses or through the hands of large distributors. 

 These small lots are oftentimes used up at once upon receipt 

 and it thus becomes very difficult to obtain a sample of every 

 brand which may possibly be used in the State. If any reader 

 of this report has used fertilizer not here listed he is invited 

 to communicate with the Station and if he should have any of 

 the goods in stock and properly stored, we will send directions 

 for sampling the same and will be glad to make an analysis 

 free of charge. Directions for sampling should be asked for 

 before samples are sent. 



Activity of Organic Forms of Nitrogfn. 



Concerning the activity of the various forms of organic nitro- 

 gen used for fertilizing purposes there has lately been much 

 discussion, and it is realized that this is an important question 

 both to the manufacturers and to consumers. In all of the 

 New England States and in New York and in New Jersey the 

 experiment stations have been working for some time to obtain 

 a method by which comparable results could be arrived at. A 

 method has been devised under which work of this kind is now 

 being done by two stations. The increased funds which will 

 next year become available to the Maine Experiment Station, 

 owing to the increase in the fertilizer license fee, will allow for 

 considerable work along this line and it is now planned to issue, 

 after this year, a report in which the activity and availability 

 of the different forms of nitrogen will be discussed.
