8 MODERN HIGH FARMING. 



sulphuric acid and fertilizer manufacture in this country ; but there 

 still remains an immense majority of farmers great and small, high 

 and low, in north, south, east and west, who have made no study 

 of scientific agriculture ; who have not kept pace with the times ; 

 who even look with suspicion and distrust upon those who would 

 enlighten them ; and who are to-day unable to understand why their 

 annual crops, though perhaps rotatory, are no longer so abundant, 

 nor of so good a quality as they were wont to be thirty or forty 

 years ago. Ours being essentially an age of thought and progress, 

 the time has come when every man must realize that agriculture can 

 only remain a profitable pursuit, on the condition of yearly obtain- 

 ing from every acre a maximum and cheap return, and that in order 

 to succeed in this he must restore to the soil those elements which 

 it once contained, but which in the process of nourishing the plants, 

 have been absorbed and taken away.
