CEP AGES. 195 



The Othello has certainly been too much propagated in 

 France, for the different reasons above-mentioned, and actu- 

 ally it must now always be discarded. 



It has been noticed that, when ungrafted, Othello 

 possessed a certain resistance to chlorosis. B. Chauzit 

 pointed out this fact that Othello grew without becoming 

 attacked by chlorosis in soils containing up to 50 per cent, 

 of carbonate of lime. Similar facts have been noticed else- 

 where. The writers were the first to point out that this 

 resistance to clorosis was due to its relationship with V. 

 Vinifera. Othello has been known to remain green in 

 chalky and marly soils where Noah, Riparia, Rupestris, and 

 Vialla quickly become yellow and stunted. If, however, 

 these soils are favorable to the action of phylloxera, it only 

 lives a few years. Let us remember this fact that Othello 

 resists chlorosis ; it is the only quality it inherits from V. 

 Vinifera. 



Canada, Brandt, Secretary, Cornucopia, Autuchon. The 

 same phenomena of adaptation to calcareous soils which 

 have been pointed out for Othello also apply to these cepages. 

 This is again due to the influence of V. Vinifera. 



We have shown, at the beginning of this work, a special 

 case with reference to Cornucopia. Let us notice that the 

 Secretary, the most influenced by Vinifera and therefore the 

 least resistant of these hybrids, is also the least affected by 

 chlorosis in calcareous soils. Canada, Brandt, and Autuchon 

 have the same faculties of adaptation as Othello. 



Autuchon is the most resistant of all of these to phyllox- 

 era (7) ; this explains its greater vigour in certain marly 

 calcareous rather poor soils. It bears white non-foxy grapes, 

 with a special agreeable taste, but has very slight produc- 

 tiveness, and is therefore without cultural value. 



The Secretary derives from the Muscat Hamburg large 

 fruit, juicy, with a slight Muscat taste; it is fructiferous, 

 but its resistance is only slightly superior to that of varieties 

 of V. Vinifera. Canada and Brandt are less resistant, and 

 less resistant than Othello, but their fruit has a clean taste. 



As for the Cornucopia, it not only produces less than 

 the latter (Othello), but its fruit is almost as foxy; it is, how- 

 ever, the most vigorous of all. 



None of these cepages can render any service ; their culture 

 should be entirely abandoned everywhere.
