fertile it will of course thrive the better, although under these 

 circumstances the Riparia will excel it. Thus speaks Professor 

 Viala, a recognised authority on viticulture, on Rupestris : " Among 

 the diverse forms of Rupestris, we recommend the following from 

 a strictly practical point of view as the most valuable in i-eplanting 

 vineyards : Rupestris Monticola (Du Lot or St. George), Rupestris 

 Martin, Rupestris Mission, and Rupestris G-anziii. These alone 

 should remain under culture. The others, though possessing a 

 certain undoubted value, are inferior, because they lack resistance 

 or all-round adaptability. The Rupestris Martin, on account of its 

 great resistance to the Phylloxera, should always be used in poor, 

 silicious, gravelly soils, with or without a considerable amount of 

 lime. The Rupestris St. George replaces actually the Leiioir and 

 Solonis in poor calcareous soils where formerly the Vialla, Lenoir, 

 etc., were used. The ungrafted Rupestris will frequently show an 

 alarming number of black spots on the leaves, so abundant in some 

 cases as to cause the dropping of a few of them. This is due to 

 the Melanose, a disease of the vine that never does any harm at all 

 and should alarm no one. As soon as the Rupestris is grafted this 

 will disappear from the vineyards, as it can scarcely live on the 

 Vitis Vinifera, but takes more kindly to the American vines." 



The Rupestris have a low, bushy growth, with young wood, 

 reddish brown. Tendrils discontinuous and leaves small, light 



Bupestris Moiiticola.
