Composition of Raw Materials. — In order to form a correct idea 

 of the cost per pound of the fertilizer constituents of these ma- 

 terials, it is needful to determine their composition; or, in other 

 words, the quantities of valauble constituents each contains. The 

 folloAving table shows the composition of the raw materials used 

 in the manufacture of fertilizers. Very few analyses of these 

 materials, with the exception of ground bone and dissolved rock, 

 have been made in Pennsylvania. The figures in the following 

 table include the averages of the results of analyses made in Con- 

 necticut, Massachusetts, New Jersey and Pennsylvania during the 

 past year, except in the case of ground bone and dissolved rock 

 phosphates, where Pennsylvania results alone are included.
