PART VII. 



METHODS OF ANALYSIS 



CHAPTER CXXXII. 



REMARKS. 



'"PHE sciences mainly helpful to agriculture are Geology, 

 Mechanics, Botany, Chemistry, Veterinary Science, 

 Zoology and Bacteriology. It is not expected that an agricul- 

 turist or scientific farmer should be an expert in all these 

 sciences, In treating the subject of agriculture in a systema- 

 tic manner it is impossible to ignore the geological, mechani- 

 cal, botanical, zoological, physiological, bacteriological or 

 chemical aspects of various questions with which the agricul- 

 turist has to do, and in the preceding Parts of this book facts 

 culled from these sciences which are intimately related with 

 agriculture, have been freely made use of in explaining the 

 reasons and principles underlying those questions. We have 

 already dealt with the chemical aspect of soils, crops, manures, 

 &c., and in this Part, therefore, we will deal only with the 

 methods that an educated farmer may follow for himself, 

 without going to a chemist in analysing soils, manures and 

 food-stuffs. 



1,387. The main purpose of a knowledge of agricultural 

 chemistry on the part of the agriculturist, is to enable him to 

 analyse soils, crops, manures, purchased food-stuffs, milk, and 

 industrial products, such as indigo, tea, sugar, dyes and tans.
