OFFICIAL REPORT OF THE PROCEEDINGS OF THE 



sun. In September after the graft has taken, remove the mound and 

 any roots that may have grown from the cion. Now the vine is perfect. 

 Where grafting has been done below the surface it will be necessary to 

 dig around the plant yearly and remove roots that will form on the cion, 

 or else these roots will draw nourishment from the leaves to the detri- 

 ment of the resistant roots below. Phylloxera will then kill the upper 

 roots and the vine sickens and dies. Apart from the cost, Mr. Dresel 

 further states that they met with no serious drawback in replanting one 

 hundred and fifty acres, and it would require a tedious search to find 

 a single dead vine. 



In 1890 this vineyard produced 50,000 gallons of wine. Last year it 

 was still thrifty and productive, amply repaying superior care and 

 cultivation. 



Riparia stock has been used to advantage upon the Senator Fair 

 estate near Lakeville. When the phylloxera made its appearance there 

 a decade ago, the situation was thoroughly canvassed and arrangements 

 were perfected to replace with resistants the old vines as they suc- 

 cumbed to the ravages of the pest, and add enough to bring the vine- 

 yard up to a round five hundred acres. A visit there this year showed 

 that the Riparia is making a vigorous growth and that the new vines 

 are entirely healthy. Grafting goes on yearly as extensively as the 

 season will permit. Blocks of vines grafted in 1898 yielded upward of 

 a ton per acre this poor year. 



Certain varieties of the Riparia are especially adapted to the deep 

 black loam or adobe soils of the Bay region, where the beneficent fogs 

 are almost equal to a succession of showers, but the wine-growing center 

 has steadily receded from the bay and the phylloxera has just as per- 

 sistently followed the movement in quest of its preferred food. 



While the Riparia strikes diagonally into the rich soils of the Bay 

 region, it quickly resumes its natural habit of lateral rooting when it is 

 planted inland. In its Missouri home it is found growing along the 

 river bank, from which it takes its name. 



The Lenoir and Tokay do very well in deep alluvial soils. 



The Rupestris St. George, a rock-climber, is a favorite for the drier 

 upland soils of the interior, on account of its deep-rooting qualities. 



The Rampendahl Vigorosa was first named " Vigorosa " on account 

 of its vigorous growth, and later "Rampendahl" was affixed in honor 

 of its discoverer, Prof. A. C. Rampendahl, of St. Helena, who found 

 the vine on the side of a mountain ravine, while on a hunting trip in 

 1885. He was attracted by the beauty of its long, uniform, reddish 

 trunk, which was from 35 to 40 feet in length, with an average diameter 

 of four inches. Napa County was sadly in need of a reliable resistant 

 stock to renew her fast failing vineyards and restore land values by 

 making the ground profitable. This vine was something entirely new.
