 down that it will not hold the stock firmly. The suc- 

 cess of the operation depends mainly on a close junction 

 of stock and cion from the top to the bottom of the clef fc. 

 The third man follows, drawing well-pulverized earth

 soon after the operation. It serves as a protection to 

 the young graft, and the young, tender growth, when it 

 appears, should at frequent intervals be tied to the stake. 

 Suckers from the stock should be promptly removed.

SELECTION OF VARIETIES. 



The whole success of the vineyard may depend on a 

 proper selection of varieties. It is, however, almost im- 

 possible to give general rules, as some soils are especially 

 adapted for producing the choicest red wines, while 

 others will give that delicacy of flavor, that sprightliness 

 and fullness especially admired in the Hocks and Stiu- 

 temes, of which the Riesling and the Semillion may be 

 considered the leading types. Generally we expect the 

 finest red wines from soils rich in iron, to give them the 

 fine, violet color, the tannin and fine bouquet, while the 

 finest white wines are generally produced on lighter col- 

 ored, gravelly soils. That there is an immense difference 

 in soil and location goes without saying. The cultivator
