ON THE MANAGEMENT 



keep them regularly fastened to the rafters : divest 

 them also of their wires, and also of their laterals 

 whenever they appear ; but, above all, guard well 

 against insects, particularly the Acarus, or red 

 Spider: the rapid, though insensible depredations 

 sometimes committed by these minute intruders, 

 are really astonishing. But I shall have occasion 

 to speak more fully on this head in another 

 place* 



The Vines may be permitted to run two-thirds 

 of the length of the rafters, or, in general, about 

 twenty or twenty-five feet, before they are stopped; 

 and those that grow remarkably strong, may be 

 suffered to run the whole length of the rafters, or 

 about thirty feet. 



When the Vines were planted in the large hot- 

 house at Welbeck, in 1779, I permitted, by way of 

 curiosity, a remarkably vigorous-growing plant, of 

 the white Muscat of Alexandria, to make a random 

 progress after it had got to the top of the rafter. 

 It was trained sideways along the top of the stove. 

 It continued to grow till late in the month of 

 November, when, on taking the measurement of 

 the shoot, I found it forty-six feet seven inches q in 



i The following account of the surprising progress of some 

 Vines last summer, at Kelmarsh, in Northamptonshire, ad- 

 dressed to me by William Hanbury, Esq. will, I trust, prove 

 highly acceptable to my readers : 



" Agreeably to your request, I herewith transmit you an 

 account of the progress of the Vines I had from you in Novem- 

 ber, 1786. The surprising shoots they have made in one 

 season have astonished every one who has seen them.
