The most formidable enemy, however, of both the blackberry and raspberry is what is called the Orange-rust (CT-erfo ruborum): It is perhaps more abundant on the Black-cap raspberry (Rubus occidentalis') than on the ordinary varieties of the blackberry; still it is sufficiently abundant and destructive to all to attract the attention of horticulturists throughout the country. I do not know of any remedy except to stamp out the disease by rooting up every affected plant and burning it. It may be that applications of lime, salt, or some similar substance would check the disease, and while these may be safely tried as preventive measures, the destroying of all infested plants should not be omitted. The Raspberry.—As the raspberry is closely allied to the blackberry and belongs to the same genus, the diseases and insects infesting both do not materially differ. Some few species of insects seem to prefer the raspberry, notably among wliich is what is called the Red-necked Buprestis (^ ruficollis), a small beetle that seems to be particularly fond of the red and black-cap varieties, but will occasionally attack the blackberry. The larva bores the canes in summer, causing large excrescences or galls, checking the flow of sap, and causing the death of the cane. This insect seems to be far more plentiful in the western than eastern States; but. it is widely distributed, and every cultivator of the raspberry may as well be on the lookout for it, and gather and bm-n all canes upon which galls of any kind are found. agrhus kuficolus. The snowy Tree-cricket (CKcanZ/M/s niveus) is another insect that appears to prefer the canes of the raspberry as a nidus for its eggs to the twigs of other shrubs or trees. It will,
