 culiar topographical features. Thus a range of hills 

 or a belt of woods, may so deflect the prevailing 

 winds, as to completely change the condition of two 

 localities situated within even a very short distance 

 of each other. 



In general, it will be found necessary to secure pro-

 be afforded either by natural local features, as by a 

 range of hills, or it may be derived from artificial 

 sources, as woods or fences. No defence is better 

 than a good belt of Norway spruce, and if they form 

 a crescent in which the vineyard is embowered, but 

 little danger need be apprehended from violent winds. 

 Even high fences, which may be single, double or 

 triple, afford aipnle protection in ordinary cases, and 

 as trees, even of the fastest growing kind, take a con-
