The foregoing remarks apply to hill vineyards as well as to those 

 in the different valleys in the county. Napa Valley, with its surround- 

 ing hills, has not alone suffered in this matter, though vineyards in 

 other valleys in the county are few in number and of limited extent. 

 In Gordon Valley, within the last two years, vineyards have been 

 devastated by phylloxera. In Berryessa Valley little attention has 

 been paid to the cultivation of the vine. The small vineyards of Pope 

 Valley are growing smaller. In Wooden and Capelle Valleys there are no 

 vineyards worthy of note. These smaller valleys are so difficult of access 

 and the mountain roads leading to them are so long and rough, that 

 land owners have been deterred from planting vineyards. Perhaps it 

 is as well. Foss Valley vineyards, all of limited area, are still in fair 

 condition. On the Suscol hills, since my last report, whole vineyards 

 have been uprooted, because of the rapid devastation by the ubiquitous 

 phylloxera. 



Very many vineyardists fully appreciate the efforts of the Commission 

 to spread information regarding the success that has attended the plant- 

 ing of resistants. They will gladly avail themselves of published facts 

 and the experience of those who have planted resistants to any extent. 

 It is evident this useful information will be of great practical benefit to 

 all concerned. The last reports of the California Viticultural Commis- 

 sion, issued this fall, have been extensively circulated in this county, 

 and, by a large majority of vineyardists, were gladly received. 



I have endeavored to carefully and conscientiously follow the instruc- 

 tions given me. I have made a complete canvass of the vine-growing 

 districts of the county. The results of my observations and inquiries are 

 embodied in this report and contained in the blanks furnished. While 

 I would not act the pessimist, but w r ould give as hopeful a report as 

 possible, it is useless to hide the fact that our vineyards are melting 

 away, as the mist before the morning sun. 



In resistant stocks the only remedy for preserving our vineyards has 

 been found. It has already been stated that vineyards so rooted will be 

 comparatively few. I think an investigation of the matters submitted, 

 made two or three years hence, will prove the facts stated and forecasts 

 made to have been true. 



I trust my efforts to follow and carry out your instructions will meet 

 with your approval and will give complete satisfaction. 



Respectfully submitted. 



A. W. ROBINSON. 



The above report is indorsed and submitted to the Commissioners.

 Commissioner for the Napa District. 



SUPPLEMENTAL REPORT. 



NAPA, December 10, 1892. 



It would be exceedingly difficult for any one to accurately judge of 

 the amount of vineyard acreage in this county now infested by phyl- 

 loxera, even approximately. Some vineyards, and they are not a few,
