 sale deliveries of the year are contracted for. The prices fixed are

Composition of Paw Materials. 



In order to form a correct idea of (he cost per pound of the fertiliz- 

 ing constituents of these materials, it is needful to determine their 

 composition; or, in other words, the quantities of valuable materials 

 each contains. With the exception of ground bone and dissolved rock 

 phosphates, very few of the single ingredients of fertilizers have been 

 analyzed in Pennsylvania during the past year; in the following 

 table, the averages include the results of analj'ses made in Massa- 

 chusetts, Connecticut, New Jersey and Pennsylvania, except in the 

 case of ground bone and dissolved rock phosphates, where Pennsyl- 

 vania results alone have been included.
