38 HANDY-BOOK OF HUSBANDRY. 



Having in the foregoing remarks struck what I believe to be 

 the key-note of the scientific practice of agriculture, and indicated 

 the points which seem to me to be of the most vital importance to 

 every farmer who would regulate his operations, so far as is possi- 

 ble, by what is positively known of the fundamental laws of fer- 

 tility and growth, I proceed to the consideration of the daily de- 

 tails of his business, the " How to do it" of practical farming ; 

 — and I shall, whenever the occasion offers, recommend that the 

 treatment of the soil and its products, of the live stock of the farm, 

 and of manures, be based on what has already been shown to be 

 the very groundwork of true economy in agriculture.
