88 MODERN HIGH FARMING. 



home-made chemical manures as the natural outcome of practical 

 experiment. 



The manufacturer who has suitable works, and produces on the 

 large scale; who has the needful knowledge and practice, and the 

 needful implements at hand, buys his raw material by cargoes to the 

 best advantage. He can therefore very easily furnish well-made com- 

 pound manures, and guarantee them by chemical analysis to contain 

 the elements desired, at a price which, all things considered, will be 

 less than the cost of home fabrication. 



With soluble or precipitated phosphates as the basis of operations, 

 we can now obtain complete manures for every culture, made accord- 

 ing to any formula, and containing in a readily available and 

 assimilable form all the ingredients called for. 



The raw materials having already been dwelt upofa, and their 

 attributes and chemical composition described, it is only needful to 

 atdd that when the due proportions of each kind have been accurately 

 weighed, they are all mixed up together by special machinery, and 

 so carefully ground, sifted and blended, as to make it impossible to 

 distinguish with the naked eye that any mixture has taken place.
