By the kindness of Mr. Charles Joly, we have received the report of M. Tisseraud, on the efforts made to conquer this foe to the vineyard during the year ending 1880. It is very pleasant to learn from M. Tisseraud that " the Phylloxera, like the vine mildew, is in a fair way to be conquered by science." It appears the insect can certainly be destroyed, wherever the grapes are in a situation to have the roots submerged during the winter season, and some useful insecticides have been discovered. The best preventative is the roots of American species.
