ON VINERIES. 



twenty-five pounds weight of fruit, depending on the 

 variety as well as the health and strength of the plant. 

 It is easy to understand the weight mentioned above may 

 often be produced in four, five, six, or seven bunches. 

 Nothing further need be said, I think, relative to the 

 cropping of the vine than this, that it seems necessary 

 to study and cling closely to nature. It can only be by 

 careful attention, and taking especial pains, that we can 

 arrive at perfection in the cultivation of the grape vine. 



Everything appertaining to the sound basis on which 

 Sir Humphry Davy worked should be well studied. 

 Notice the time when he discovered the metallic base 

 of potash (potassium), which was the principal cause of 

 the field being opened to horticultural and agricultural 

 inorganic chemistry. No sooner did he accomplish this, 

 in 1807, than a German chemist — evidently trying to steal 

 a march over him — by experimenting on soda discovered 

 that the metallic base of it was sodium, by the same 

 process as Sir Humphry Davy discovered the metal called 

 potassium. After this, Davy discovered all the principal 

 alkaline bases by the same means as he made use of for 

 potash. 



If the inexperienced gardener or amateur will care- 

 fully study and follow the above instructions, I have no 

 hesitation in saying that he will meet with success, and 

 I hope to his satisfaction. I have dwelt rather long on 



this branch of the subject; but I think it an invaluable
