comparatively free. For this reason, it is advisable to 

 keep the doors and lower ventilators closed, and admit 

 air only by the upper openings until the fruit begins to 

 lose its acidity, after which there is no danger. 



The antidotes to mildew are a warm and dry atmos- 

 phere, and sulphur. Whenever it is detected, do not use 

 any water inside the house during cloudy or damp 

 weather, and sprinkle sulphur over the floor in the pro- 

 portion of one pound to each fifteen square yards. There 

 is no occasion to throw it over the plants inside the house, 

 but in the vineyards or out-doors, it will be requisite to 

 dust it in an upward direction, so as to adhere to the 

 under side of the leaves, and prevent the rains from 

 washing it off. The fumes given out by slow combustion 

 are the remedy, and care should be taken that it is not 

 ignited. Mistakes have frequently been made by per- 

 sons introducing burning sulphur into graperies and 

 plant-houses, as well as using it under the leaves of trees 

 out-doors, the consequence of which is, a total destruction 

 of the foliage, if not death to the plant. 



OTJT-DOOR CULTURE. 



Continue to keep the ground clear from weeds, using 

 the hoe freely, but do not injure the roots. Remember 

 that every weed draws moisture out of the eaj'th, while 

 every stroke of the hoe enables the dews to penetrate. 

 Wherever it is possible, a good mulching of barn-yard 

 manure, or any kind of vegetable reftise that is free from 

 weeds, ought to be spread over the whole surfixce, which 

 will assist in keeping the soil moist, and promote the 

 vigor of the vines. Do not let the growth bcicome 

 crowded. Nip out the side laterals on the young canes 

 down to the lowest leaf upon each, and the new growth 

 of the fruit spurs in the same way to where last stopped.
