Our excellent French correspondent, Mr. Jean Sisley, says that it has been found in that country that about 6 pounds of salt to 100 quarts of water has been found a complete cure for mildew and other low cryptogamic forms of plant life that bother the cultivator. This is likely to be a very valuable hint. Salt has always been known to be injurious to vegetation, in large quantity, but it has not been known that a smaller quantity will kill fungi, and yet not harm the higher forms of vegetation. It seems to us that even a lesser quantity than that named might be used first with the water.

In answer to "J. S." (page 12, January number Gardeners' Monthly) I would say, syringe your roses lightly - just enough to wet the foliage; then apply a little flower of sulphur with the sulphur bellows, and if it is not a very bad case this will check it. Also mix a little sulphur and lime water or tobacco water to the consistency of paint and apply it to the coldest end of your flue; that is, providing the coldest end does not get heated to over 2oo°. If hotter than that it might injure your plants. My experience is that the above operation ought to be done every week during the dull winter months, on the principle that prevention is better than cure. Cold draughts, low temperature and muggy weather are all favorable to the development of mildew. Therefore, guard against them by keeping the temperature of your house as near to 6o° at night as possible, with 10° or 150 higher during the day, and you will find your roses will be clean and healthy.

A French Discovery Of A Cure For Grape Mildew

Lime and sulphate of copper has been found, when syringed over grapes, as a perfect cure for mildew. The solution is thus prepared: From 30 pounds to 50 pounds of lime and sulphate; each is dissolved in a barrel containing about 100 gallons of water. The operator dips a small heath broom in the liquid, and walking backwards sprinkles the vines. About 14 quarts to 1000 vines, the expense being a'little over five dollars an acre.
