IN the study of agriculture an acquaintance with 

 a number of sciences is necessary. Promi- 

 nent among these are chemistry and botany, some 

 knowledge of chemistry being necessary in order 

 that the changes taking place in soils under tillage 

 and cropping may be understood and the require- 

 ments of the crops economically supplied. The 

 sugar grower, being also as a rule a sugar manu- 

 facturer, requires to know some chemical facts in 

 order that he may understand the changes to which 

 sugar is liable, and how to promote advantageous 

 ones while preventing those which are harmful. A 

 knowledge of the fundamental principles of plant 

 life and nutrition is quite invaluable to all engaged 

 in agriculture. 



One of the most important facts which chemistry 

 has taught us is the indestructibility of matter : 

 nothing is created, nothing is destroyed in the con-
