ON THE CULTURE 



Be particular in not suffering them to rufi 

 to too much vine ; six joints is quite sufficient at 

 the firsthand afterwards always keep them topped 

 at the first or second joint. By strict attention 

 to this mode of treatment* you may ensure a 

 more abundant crop, and much finer fruit, than 

 can be calculated upon from the usual method 

 of suffering the vine to grow to a considerable 

 length, which tends materially to weaken and 

 exhaust the plant. 



Let them be kept under the glasses as long as 

 possible, without danger of injuring them, admit-

 when the weather is warm, by means of a piece 

 of wood, in the form of a wedge, about seven 

 inches long, five inches wide, flat, and about 

 three inches at the top. This will enable you to 

 rise or fall the glass according to the quantity of 

 air necessary to be admitted. 



Before placing the vine outside the glasses, 

 it will be necessary to admit a larger portion of 

 air, both night and day, for three or four days,
