but this would destroy the vines. Growers have, there- 

 fore, to be very careful how they use sulphur. As 

 soon as the grapes have nearly finished stoning, I mix 

 unslaked lime with sulphur of the best quality and 

 water, in the following proportions : — One medium-sized 

 lump of lime to a bucketful of water and 2 lbs. of 

 sulphur ; stir and mix it all together, making it the 

 thickness of paint ; then with a whitewash brush paint 

 about two-thirds of the surface of the hot-water pipes 

 or flues. I have adopted another plan with success, 

 viz. pouring cold water on the pipes and flues, and 

 then dredging them with as much powdered sulphur as 

 can be got to stick on the pipes, but only a slight scat- 

 tering on the flues. Care must be taken that the flues 

 are not made too hot, as they are liable to set the 

 sulphur on fire, which would destroy both fruit and 

 foliage. Choose a still night for the operation. If the 

 atmosphere is moist and dull, so much the better ; the 

 fumes then stay longer in the house, and are therefore 

 more dense. I advise to begin about four o'clock in 

 the afternoon to push on the fire, getting the pipes very 

 hot by the time the sun has gone down, so as to raise 

 the temperature the first night to 85° at eleven or twelve 

 o'clock at night; but this temperature must not be ex- 

 ceeded. Examine the leaves carefully next morning 

 with a magnifying-glass. This will enable you to find out 



whether the spiders are destroyed or not; if not, repeat
