soils it appears that it also g'ives excellent results on decomposed 

 granite (hillside), resting on Malmesbury slate as we find at Elsen- 

 burg. In one instance in Agter (iroenberg, Hanepoot grafted both 

 on this stock and on -huquez stood side by side on the same deep, 

 cool, ])iountain land and were trellised ; the former showed more 

 vigorous g-rowth, better wood, had a much better colonr (late in 

 January, 1920), and had a better crop than the ^ines grafted on 

 Jacquez, although the latter was l)y no means poor. 



Near llobertson we came across an interesting instance where 

 Hanepoot on Riparia Gloire de Montpellier, twelve years old, has 

 proved an immense success on stiff red Karroo soil. The surface soil 

 is a heavy red loam, only 5-10 inches deep, and lesting" on a hard 

 lime bank, which, however, does not contain sufficient lime to produce 

 chlorosis (leaf yellowing;). This vineyard is irrigated in the summer. 

 At the time of the inspection (about the middle of January) the vine- 

 yard had last been irrigated a month previously, and the vines were 

 still shooting and in the pink of condition. They were laden with 

 well developed grapes with sweet Hesliy berrie-s, wliich were ripe 

 eight to fourteen days earlier than the Hanepoot on Jacquez. The 

 vineyard on Jacquez, on the same type of soil, had a much worse 

 colour and was showing no signs of sprouting", altliough it had been 

 irrigated after the Hanepoot on Riparia. Complaint is sometimes 

 made that Riparia does not support its scion because of its compara- 

 tively slower growth and the tendency to produce top-heavy vines. 

 Although there is sometliing in this statement it applies to Rip. Gloire 

 de Montpellier only in its first few years, that is when it is ])lanted on 

 suitable soil. 



Mourvedre and Rupcsiris A'o. 1202. — -This is ])robably the most 

 luxuriant grower amongst the American stocks in use here. It is 

 only during the jjast ten years that it has been grown to any appreci- 

 able extent, and more particularly as a stock for Hanepoot. It is 

 used mostly in the Constantia area and in the Districts of Robertson, 

 Montagu, and Worcester. The oldest established Hanepoot on 1202 

 which the commission encountered was fifteen years old., and was still 

 doing well. Because of its vigorous growth Hanepoot grafted on it 

 has a tendency towards non-setting. The grapes usually ripen eight 

 days later than those grafted on Jacquez when planted on the same 

 soil. During the first three years Hanepoot grafted on the stock will 

 show odd failures, but later, however, the vines do well. It is not 

 regarded as a very suitable stock for Hanepoot, but with other 

 varieties of grapes this difficulty is not experienced. On most soils 

 it generally does well, excepting in sandy soils, especially those which 

 are damp, in which it is easily destroyed by root eels. On clay soils 

 and Karroo soil it is a very suitable stock. On account of its vigorous 

 growth it is very useful for poor soils, although in such a case it must 

 receive a liberal treatment of manure in view of the fact that, 

 according to European experience, it is less able to withstand 

 phylloxera than Aramou, but is better in this respect than Jacquez. 



101-14, 3300, 3309. — These three hybrids of Riparia and Rupestris 

 are not used to any great extent. 101-1-1 is the best, and up to the 

 present is most popular. In a large measure it has a Riparia 

 character. In the Commission's experience it was a complete success 

 everywhere. Hanepoot (ten years old and sometimes older) on this
