Composition of Kaw 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 valuable constituents each contains. The 

 following table shows the composition of the raw materials used 

 in the manufacture of fertilizers. No analysis of these materials, 

 with the exception of ground bone and dissolved rock, have been 

 made in Pennsylvania. These figures in the following table include 

 the averages of the results of analyses made in Connecticut, New 

 Jersey and Massachusetts during the past year, except in the case 

 of ground bone and dissolved rock phosphates, where Pennsylvania 

 results alone are included.
