If the contributions of chemical science to modern civilization 

 were suddenly swept away, what a blank there would be ! If, on 

 the otlier hand, every person were acquainted witli the elements of 

 chemistry and its bearing upon our daily life, what an uplift human 

 efficiency would receive ! It is to further this latter end that this 

 book has been prepared. Designed particularly for use by students 

 of agriculture and home economics in secondary schools, its use will 

 do much to increase the efficiency of the farm and the home. In 

 the language of modern educational philosophy, it " functions in the 

 life of the pupil." 



Useful facts rather than mere theory have been emphasized, 

 although the theory has not been neglected. The practical char- 

 acter of the work is indicated by the following selected chapter 

 headings :
