_Other Raisin Grapes._--In Asia Minor, the Grecian Islands, Morea, Italy, Spain and Morocco, there are grown a number of varieties of grapes which are cured into raisins and sold as such. Many of these are little, if any, better than our dried grapes, while others again are superior, more resembling the regular raisins. Among the latter we have the Spanish Black and Red, and the Smyrna and Turkish Black and Red. Some of them belong to the Muscat family, probably resembling Black and Red Muscats, but of these varieties we have no particular information, and our growers will probably not lose much by avoiding a more intimate acquaintance with them. DISEASES AND INSECT PESTS. The following short account of the diseases and insect pests is not intended to be exhaustive, and is only intended to refer to the raisin districts of our State. I have not included accounts of the phylloxera nor of other insects or fungi which do not exist in these districts, but which may be troublesome in other parts of the State. Strictly scientific descriptions have purposely been left out, but I have endeavored to make the popular account as correct and as condensed as possible. Of insects and fungi I have only enumerated those which are of importance through the damage they occasion from time to time. Those which prey on the vines, but which cause no great damage, and which the grower need not prepare himself to fight, have here been left out. POWDERY MILDEW OR UNCINULA. _General Notes._--This disease of the grapevine is caused by the growth of parasitic fungus known in Europe as _Oidium Tuckeri_, and in this country as _Uncinula spiralis_ or powdery mildew. I am satisfied the two names signify the same fungus, only the European form has never been found as highly developed as the American one, which has on that account received a name of its own. If the two are identical, then the European Oidium, which for many years caused the destruction of the transatlantic vineyards, was imported to that country from this. The _Uncinula spiralis_ is undoubtedly native on our indigenous vines.
