First Principles of Soil Fertility 
By AtrreD Vivian. There is no subject of more vital 
importance to the farmer than that of the best method 
of maintaining the fertility of the soil. The very evident 
decrease in the fertility of those soils which have been 
under cultivation for a number of years, combined with 
the increased competition and the advanced price of labor, 
have convinced the intelligent farmer that the agriculture 
of the future must be based upon more rational practices 
than those which have been followed in the past. We 
have felt for some time that there was a place for a 
brief, and at the same time comprehensive, treatise on 
this important subject of Soil Fertility. Professor Vivian’s 
experience as a teacher in the short winter courses has 
admirably fitted him to present this matter in a popular 
style. In this little book he has given the gist of the 
subject in plain language, practically devoid of technical 
and scientific terms. It is pre-eminently a “First Book,” 
and will be found especially valuable to those who desire 
an introduction to the subject, and who intend to do subse- 
quent reading. Illustrated. 5x7 inches. 265 pages. Cloth.
