and Verdal. These three varieties, in many cases where they looked 

 very bad last year and even this spring, appear to be recovering. 

 Other varieties show little or no damage. The chief of these noticed 

 were Trousseau, Cabernet-Sauvignon, Pinot (?), Verdot, Robin noir, and 

 Herbemont. This list indicates that the heaviest bearers are the most 

 seriously affected and that all the immune varieties are light bearers. 

 This difference in varieties was so marked that several Trousseau vines 

 growing in a Mataro block were apparently perfectly healthy and 

 vigorous, while the Mataro were all dead. This is shown in the photo- 

 graph (plate 2). The recovery of less susceptible varieties, such as 

 Grenache, was in several cases very remarkable. Two adjacent blocks, 

 one of Grenache and the other of Mataro, showed a remarkable contrast

when examined in August of this year. Both blocks had made very 

 short growth in 1900, but this year all the Mataro were dead, while 

 none, so far as could be seen, of the Grenache had died, and though the 

 block had looked sickly in the spring, when examined in August it 

 showed a fine growth of luxuriant foliage (see plate 3). 



To recapitulate; the main facts ascertained are: 



1. All the dying vines are old. 



2. All the serious cases are in gravelly soil. 



3. The varieties most injured are all heavy bearers. 



4. Vines grafted before the drought are healthy. 



5. Vines showing serious mechanical injuries succumb first. 



6. Vines which have not become too weak appear now to be recov- 

 ering.
