EDITOR'S NOTE 



THIS little text has been prepared in the belief that 

 boys attending high schools in farming communities and 

 those taking short courses in agricultural colleges should 

 receive instruction in the chemistry applying to farm prac- 

 tice. For such students, there is neither time nor oppor- 

 tunity for the usual formal course in General Chemistry, 

 followed by technical Agricultural Chemistry. A single 

 elementary course combining the two is possible, in which 

 the information furnished is definite, practical and reason- 

 ably adequate. 



In such a combined course, the essential principles of 

 Chemistry naturally come first, to be followed by their 

 applications to the problems which arise in the life on a 

 farm, in the growing of farm crops, or in the feeding and care 

 of farm animals. This order has been followed by the author 

 in the present text. It is believed that teachers in high 

 schools attended by boys living on farms and in agricultural 

 colleges giving short courses will find in The Chemistry of 

 Farm Practice the text-book best suited to their needs. 

 It should prove especially valuable, also, as a reference 

 book for those interested in farming.
