Oct. 5. — Vibert's Nursery, at St. Denis, was commenced in 1828; M. Vibert having been driven from his former situation at Paris by the ravages of the ver blanc.* The only article which he cultivates is the rose, of which he has several hundred varieties, a great many of which were raised by himself from seed. When he has procured a new and valuable sort, especially if it belongs to the Indian species (Rosa indica and semperflorens), he buds it on the current year's shoots of a stool of the Rosa reversa (the original plant of this species, we were informed, was found by chance in M. Vilmorin's ground for proving seeds in Paris); lays these shoots down after the buds have begun to push; and the shoot proceeding from the bud, deriving nourishment from the roots emitted into the soil as well as from the stock, being thus greatly strengthened, pushes vigorously, so as to admit of layers being rooted and taken off the same season. This is quicker work than could be practised in England.
