126 DESTRUCTIVE INSECTS OF VICTORIA: 



"Lenoir" has been growing rapidly in favour in California, 

 because of its rapid development and easy grafting. It 

 proves difficult to root, but is preferred over the "riparia" 

 and some others, because it furnishes a wine suitable for 

 blending as a direct producer. But grafting is both ex- 

 pensive and slow, and, in fact, the value of carrying on any 

 warfare may be somewhat altered by the present depressed 

 condition of the wine-making industry and the popularity 

 and improved value of other branches of agriculture. 



A very practical series of conclusions have been arrived 

 at by the California State Viticultural Commissioners, 

 1882-83 and 1883-84, as under : 



We have learned sufficiently already to be able to 

 make public certain conclusions, viz. : 



First. That the ravages of the Phylloxera do not 

 threaten rapid destruction of vineyards in this State. 



Second. That, by using wise precautions in disinfect- 

 ing cuttings before planting, and avoiding the use of 

 rooted vines from infected districts, new plantations may 

 be made with little danger of infection, except in the 

 direction of prevailing summer winds that blow from 

 diseased places. 



Third. That whenever infection is discovered in a 

 vineyard, prompt action in substituting resistant stocks 

 for those diseased will not only check the evil, but will 

 result in such a gradual reconstitution of the vines that 

 the extra expense and losses will not be severely felt by 

 the proprietors. 



Fourth. That in all cases of new plantations in the 

 direction of known contagion, only resistant stocks should 

 be planted. 



Fifth. That fear of future trouble from this pest may 

 be avoided in any case by planting resistant stocks, even 

 though present infection is not feared. 



Sixth. That grafting upon resistant stocks may be 

 easily accomplished without extraordinary expenses, and 

 that the cost is more than compensated for by the in- 

 creased vigour and fruitfulness of the vineyards so treated. 



Seventh. That, in substituting resistant stocks of 

 those diseased, efforts should be made to eradicate as
