than during the past season, and the collection and analysis 

 of samples reach the highest nuniher ever attained dnring the 

 history of fertilizer insj)ection work in Massachnsetts. 



(a) Fertilizers licensed. 

 Dnring the year 431 distinct brands of fertilizers and agri- 

 cnltnral chemicals have been licensed in Massachusetts. Li- 

 censes have been secured during the year by 78 manufacturers, 

 importers and dealers, counting each branch of the American 

 Agricultural Chemical Company as a separate company. Two 

 more licenses were issued and 22 more brands were licensed than 

 f<n' 1008. The brands licensed this year may be classed as 

 follows : —

Fertilizers furnishing potash and phosphoric acid, . . 9 

 Ground bone, tankage and dry ground fish, ... 51 

 Agricultural chemicals and organic compounds furnish- 

 ing nitrogen, ......... 65 



Total, ......... 431 



{h) Fertilizers collected. 

 An effort was made during the season to cover a larger terri- 

 tory than heretofore, and to procure, so far as possible, repre- 

 sentatives of every brand of goods sold in the State. As a 

 general rule, fertilizers cannot be found plentifully in the open 

 markets in IMassachusetts until after Ajudl 1. Some of the 

 fertilizer is used on early crops by the 15th or 20th of April, 

 and by May 1 considerable of the fertilizer is in the ground. 

 Our collecting season being relatively short, an extra man was 

 delegated to gather samples during that portion of the season 

 when the fertilizer was found most plentiful. The samples 

 were in all cases taken by an authorized agent from the ex- 

 periment station. Mr. James T. Howard, the assistant usually 

 delegated to this work, assisted by ]\fr. C. W. Gaskill, covered 

 the eastern portion of the State, while Mr. E. C. Hall looked 

 after the collection in the Connecticut Valley and the central 

 portion of the State. Samples were taken from over 280 

 different agents, and over 110 different to^\^ls were visited.
