If the contributions of chemical science to modern civilization 

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

 other hand, every person were acquainted with 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 character 

 of the work is indicated by the following selected chapter headings: 



II. The Composition and Uses of Water. 



IV. The Air, Nitrogen, Nitric Acid and Ammonia. 



IX. Carbon and Its Compounds. 



XII. Paints, Oils and Varnishes. 



XIII. Leather, Silk, Wool, Cotton and Rubber. 



XV. Commercial Fertilizers. 



XVI. Farm Manure. 



XX. Milk and Its Products. 



XXI. Poisons for Farm and Orchard Pests.
