*ver blanc (grub of the cockchafer)

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. We were rather surprised to be informed that dwarf roses on their own bottoms are considered to retain the character of the variety longer than such as are grafted. To prevent, as much as possible, the ravages of the ver blanc, the ground is covered with wheat straw, which hinders the insect from getting at the soil, and there burrowing and depositing its eggs. A hard smooth surface has the same effect, the insect being unable to burrow in it. The mole cricket is here rather troublesome; and M. Beck, M. Vibert's foreman, a German gardener, who has been in England, informed us that he had a plan for enticing the mole cricket, by an odoriferous composition, under a glass or pot, so that it might be taken and destroyed; and that his employer intended to put his plan to the test of experiment, and publish the result. M. Beck is an intelligent man; and we gave him No. III. of what is to us one of the best books in the world, viz. our Magazine of Natural History.
