CEPAGES. 151 



with reason, that these are ternary hybrids, into which 

 Rupestris also enters. The Rupestris is not to be found in 

 regions where the Novo-Mexicans grows, but Millardet gives 

 an instance of Solonis seedlings with Rupestris characters. 

 A forr$ of Novo-Mexicana, the Mobeetie, has very decided 

 characters of V. Rupestris. 



The Novo-Mexicana and Solonis have been found growing 

 together on the banks of the Red River, extreme north of 

 Texas, in cretaceous soils. The soils of the banks of the 

 Red River are generally rich, red, sandy, often moist, and 

 always fresh ; the subsoil is composed of white calcareous 

 concretions, fairly hard, fissured, through which the roots 

 penetrate. T. V. Munson has observed the Novo-Mexicana 

 in lithographic limestones and in rather hard chalky soils, 

 covered with a layer of rich blackish soil, of a thickness 

 of 14 to 16 inches. The Solonis and Novo-Mexicana grow 

 naturally in soils containing a moderate percentage of car- 

 bonate of lime. 



The Solonis is the only form of Novo-Mexicana experi- 

 mented upon in France since the invasion of phylloxera, that 

 is to say, since 30 years, and is one of the American vines 

 which succeeded best in calcareous soils, with relatively low 

 percentages of carbonate of lime, which accounts for the 

 importance it had at the beginning of the reconstitution. In 

 chalky, soft, and white limestone it generally develops well, 

 as long as it remains ungrafted. It never becomes chlorosed 

 to any extent, but when grafted it rapidly becomes stunted. In 

 ground, the soil of which is calcereous, but fresh and deep ( 16 

 to 20 inches), resting on a chalky or white marly subsoil, where 

 all other vines (Rupestris, Riparia, Vialla) become chlorosed 

 and die rapidly, the Solonis has always given good results. 

 Upon the whole, many calcareous regions have been recon- 

 stituted with success on Solonis, regions which it would have 

 been impossible to reconstitute with any other then known 

 cepage. Such were the Blayais, Charentes, south of France, 

 Dordogne, etc. In moderately calcareous, but fresh and 

 fertile soils, its grafts are fine, very fructiferous, ripening 

 early. Many vineyards planted under these circumstances 

 have now been grafted for nineteen to twenty-one years. And, 

 moreover^ it is the best graft-bearer for damp or brackish 

 soils; in the latter soils no other graft-bearers are superior. 

 Graft-bearers are actually in existence (Riparia X Rupestris, 

 Rupestris du Lot) almost equal to the Solonis so far as
