THE GRAPE. 



For private gardens where ground is scarce, th<5 vine should be 

 well supplied at its roots with liquids hereafter named, and permitted 

 to run or ramble upon lofty trellises. Spur pruning, which consists 

 in training the old, or main stem, and yearly cutting back the late- 

 rals to two or three good buds, must here be pursued ; care should 

 be taken, however, not to cut back, and preserve the same side 

 branches or spurs from year to year, lest by so doing they soon be- 

 come enfeebled, and the fruit ripens imperfectly ; but new side shoots 

 should be yearly selected of the strongest growth, and cut back to 

 the two or three bearing buds, while that of last year's bearing is cut 

 away. 



Manures. The analysis made by Prof. Emmons, of the common 

 wild grape vine is as follows : 



Wood. Bark. 



Potash 20.84 1.77 



Soda 2.06 .... 9.27 



Chlorine 0.02 0.40 



Sulphuric acid 0.23 trace 



Phosphate of lime 15.40 5.04 



Phosphate of peroxide of iron 1.2C 5.04 



Carbonic acid 34.83 . . . 



Lime 17.33 ... 



Magnesia. 4.40 ... 



Silex 280 ... 



Soluble silica 0.00 ... 



Coal and organic matter 2.20 ... 



100.21 



100.86 



From this, any one moderately conversant with the components of 

 soils can readily see what is required for his vines. Burying the 

 refuse cuttings and leaves, sprinkling on gypsum (plaster of Paris), 

 and supplying freely the soap-suds, and wash-water of a family, with 

 animal (or barn-yard) manures, and wood ashes, are most advisable, 

 aside from the specific application of potash and bone dust. 



Insects and Diseases. The aphis and slug, described fully in 

 " Harris's Treatise,'' appear in the months of May and June. They are
