Remember that each year tons of ■wood pruned away, of fruit harvested, and of leaves cut 

 by frost, and by winter winds blown from the vineyard, are the heavy tax the land bears, that 

 you may pocket from $50 to several hundred dollars per acre annually according to your deserts 

 as the owner. Fortunately, any good soil contains the many other elements necessary for good 

 growth in sufficient supply for all time; but these three, — nitrogen, phosphoric acid and potash, 

 — will soon be used up and production cease unless they are replenished from time to time. The 

 French vinegrowers appreciate these economies so well, that the best cultivators run all the prun- 

 ings of their vineyards through a mill which cuts the brush into short bits and crushes them into 

 pulp, and all is returned to the vineyard and spread over the ground and cultivated in. Also 

 the drifted leaves are piled, rotted and returned to the soil. Americans will soon have to learn 

 and practice such economics, or come to serious want.
