Summary of Reports from Growers. 



STOCKS FOR THE FRESNO REGION. 



In 1903 five plots of resistant vines were planted in the neighborhood 

 of Fresno on land kindly placed at our disposal for that purpose by 

 various growers. 



The great importance of the raisin and wine industries in the upper 

 San Joaquin Valley, and the special climatic and soil conditions of 

 that region, make it very necessary that we should, as soon as possible, 

 obtain some reliable information regarding stocks that will succeed 

 there. European experience can be relied on less in this region than 

 in the coast valleys. No part of France resembles the San Joaquin 

 Valley, and in the parts of Spain which show the most nearly similar 

 conditions the problems of resistant stocks are hardly more advanced 

 than in California. 



The five plots were planted primarily to determine the vigor of the 

 most promising stocks in the region, and to provide cuttings for dis- 

 tribution to enable growers to make tests on their own places. 



The following varieties, which include nearly all those which have 

 given the best results in Europe, were planted : 



Pure American Varieties.

3. Rupestris Martin.
