A TREATISE ON THE 



quantity of sulpliur : keep the house for a few days rather close. 

 The effect produced on the vines from this treatment was evident 

 in a few hours ; the mildew was completely checked, nay, cured, 

 and the result was as fine a sample of beautifully-coloured and 

 well-swelled fruit as could be wished for. The wood was also in 

 excellent condition, and the foliage perfect to the last. As a fur- 

 ther proof of the efficacy of this plan in making a perfect cure, 

 I will instance a house of grapes, some in bloom, and others as 

 large as peas, in the first week of November 1850. These were 

 attacked in the same manner with mildew, and treated precisely 

 as the others, and with the same successful result. My opinion 

 is, that, in applying the sulphur to the wood as recommended, the 

 strength of that powerful agent is imbibed into the pores, and it 

 consequently acts on the whole plant to which it is applied, and 

 enables it to repel the evil effects of the outward air. The wash- 

 ing of the walls, also, in a great measure, purifies the internal 

 atmosphere. It will at once be acknowledged how infinitely pre- 

 ferable this method of applying the sulphur is to the way in 

 whicli, in many cases, I have seen it used, where the bunches 

 were entirely covered with it, not only giving the fruit an unsightly 

 appearance, but in reality making it unfit for tlie table.
