METEOROLOGICAL OBSERVATIONS 



yards, for which it is so much the more dangerous, since the 

 artificially accelerated development of the vine permits its occur- 

 rence some months earlier than in the open air, and the disease 

 is in a condition to attack the bunches at a mucli younger stage 

 of growtli. It is a great question whether, now that the disease 

 is widely spread, any benefit would be derived from preventing 

 the artificial growth of grapes, as has been proposed, on one side, 

 even supposing it were, or could be, put in practice ; on the 

 other hand, there is no doubt that tiie owners of vines wliich 

 grow in conservatories or on walls can use remedies against the 

 malady when appearing in such situations. It seems at least, 

 after the experiments made in England and France, to admit of 

 no doubt that the removal of the parts first diseased, and the 

 washing with solutions of lime, sulphuret of lime, alum, soap, 

 &c., besides fumigation with tobacco smoke, and dusting with 

 sulphur, are attended with advantage.
