It [Antoine Rivoire] is a sort, too, that does not readily take mildew, although I cannot say it is mildew-proof. It is the scourge upon some of the Hybrid Teas, such as Killarney and Mme. Abel Chatenay, that so sadly mars their beauty, and that makes one wish there were more Roses like Mme. Edmée Metz, which is practically mildew-proof. I am glad to see that this mildew-proof quality seems perpetuated in a seedling of Mme. Edmée Metz named Anne Marie Soupert, so that we may hope that by using as seed parents those Roses that are mildew-proof we shall in time obtain some considerable number of this character.
