A French correspondent says: "You most likely know, that after having been invaded by the Oidium and by the Phylloxera, our vineyards are now subject to the mildew. The Oidium is beaten by sulphur. The Phylloxera, by the importation of American vines as stocks, is prevented. But the mildew continues to annoy us very much. A remedy has been used - a mixture of chalk and sulphate of copper. But it seems very dangerous, as several persons have been lately poisoned by eating grapes which had been aspersed by that mixture.
" I therefore beg you to let me know as soon as possible, what is the remedy employed with you? You would oblige me very, very much".
[It is remarkable, that though the mildew - a small lungus named Peronospora viticola - is an American pest, it is not so serious a trouble in its own country as it is when it gets among the French people. Years ago, when we had the hot-house forcing system of propagating grapes in vogue, the mildew was a matter of consternation with grape-growers; but since more attention has been given to getting plants with sound constitutions, we rarely have any correspondence seeking for remedies. We fancy it has ceased to be a very serious cause of trouble with us, though here and there people suffer. All preparations of copper are dangerous, as we all know who have to use Paris green. - Ed. G. M].
