longed effect from the gas. For dull weather, and when 

 immediate effect is desired, another more speedy and 

 more powerful remedy is to dissolve the sulphur, and 

 apply it in solution. This mode was recommended by 

 Prince, in his "Treatise on the Grape," published in 1830. 

 His mode is to take a pint and a half of sulphur, and a 

 lump of unslacked lime as big as the fist, and dissolve 

 the two together by pouring a pail of boiling water upon 

 them in a barrel. This is to be diluted by adding two 

 barrels of water, at which strength it is to be applied to 

 the vines. A pint and a half of sulphur will therefore 

 make about sixty gallons of the wash. This is too weak, 

 and the quantity of lime is also too small to dissolve all 

 the sulphur. In the twelfth volume of " Hovey's Maga- 

 zine " is a recipe for a solution, recommending one peck 

 of lime, and half a pound of sulphur, to be slacked with 

 boiling water in a tight barrel. After slacking, three gal- 

 lons of water are to be added ; and, when settled, the 

 clear liquor is to be poured off. To every gallon of this 

 mixture add forty-eight gallons of water. This will give 

 about a hundred and forty-four gallons of liquor for half 

 a pound of sulphur. In this case, the amount of sulphur 

 is far too small for so much lime and so great a dilution.
