ANALYSES. 213 



We have shown what 136*60 Ibs. of the ton is 

 worth to the farmer, as ammonia, nitrogen, pot- 

 ash, and soluble phosphoric acid. Hence, he 

 pays $28.02 for 1863-4 Ibs. of water, sand, and 

 other inert substances, which is over li cents 

 per Ib. 



We give the following quotations from the 

 circular of the wholesale agents of this Fertilizing 

 Company 



1. "A beneficent Providence has aggregated the crude ele- 

 ments of fertility in exhaustless quantities all over the world 

 upon islands of-the sea, arid in the sea and elsewhere. Nature, 

 however, does not yield her treasures without an equivalent. 

 Coal is found embedded in mountains ; the precious metals are 

 held bound in the quartz rock, and are adapted to the uses for 

 which nature designed them, only at the cost of labor, enterprise 

 and capital. So also these deposits in their natural state are 

 not in condition for practical utility, but modern science has 

 developed methods by which they are capable of the highest 

 utility to the most important of all interests. Hence, while 

 nature furnishes the crude material, and science the method, 

 still capital, skill, enterprise and labor are required to adapt 

 them to the purposes designed by nature." 



2. " An intelligent pursuit of this business requires a know- 

 ledge of the science of chemistry, especially as applied to 

 agriculture; a knowledge of the physiology of plants, their vital 

 forces, their structure and organism ; a knowledge of the con- 

 stituent elements of vegetable nutrition, of their natural sources 

 of supply, as to whether they be of organic or inorganic origin ; 

 a knowledge of the constituents of the atmosphere and their 

 relations to cultivated plants, of the nature of soils and the 

 conditions in which the elements of fertility may exist; a 

 knowledge of the nature and character of the elements which 

 should enter int'o the composition of a concentrated fertilizer, 

 their relative proportion etc, ; n, knowledge of the difference
