AIR-ROOTS ON THE VINE. 



Though, this cannot be called a disease, it is a state 

 of things that is not desirable. It proceeds from one 

 of two causes, or both combined. Either the atmo- 

 sphere is kept too moist, or the border is too cold, and 

 probably wet, for the natural roots to make progress in 

 at the time ; and to supply the demands of a large 

 expanse of foliage these roots are thrown out. 



If the natural roots were in a border that, in texture, 

 temperature, and moisture, was congenial to their 

 nature, and the atmosphere of the vinery what it ought 

 to be, there would be no air-roots ; so that at least they 

 are symptoms of an undesirable state of things, as I 

 have already said. 



SCALDINa. 



I have used the above name for a disease that certain 

 varieties of grapes, more especially Lady Downes and 

 the Muscats, are subject to, just as they are finishing 

 their stoning. It attacks individual berries in the 

 bunches, and always during hot sunny weather. The 

 berry becomes suddenly dimpled on one side, and in 

 a few hours has the appearance of having been dipped 

 in boiling water, after which it rapidly decays. In this 

 way I have seen bunches, especially of Lady Downes, 

 reduced to skeletons. The perfect remedy for this is, 

 to give the vinery as much air as a common green- 

 house during the heat of the day, the moment the 

 disease begins to show itself, till all tendency to it is 

 over, a period of not more than fourteen days, after
