130 FURTHER OBSERVATIONS ON THE, &c. 
covering, nor are the grapes fo high flavoured as when under 
glafs. By the faintnefs of the beams of light which fuch a 
covering affords, the Vines will grow weak and long-jointed, 
and efpecially in a dull moifl: feafon, when much air cannot be 
admitted. 
When oiled paper covers are ufed, they fhould not be applied 
till the Vines begin to pufli in the natural way, and even then 
fliould be ufed at firfi; only to defend the Vines from the cold 
of the nights, for it will be neceffary they fhould have free air 
in the day-time, to prevent their drawing weak. 
The great damage done by oiled paper covers is, from the 
too dole covering at the beginning of the feafon ; but when 
the Vines come into flower, they are not fo liable to receive 
hurt by clofe covering, becaufe the wood cannot draw weak 
after the leaves- are grown to their natural fize. The ripening 
of the grapes may be greatly accelerated by covering after this 
period, and more efpecially with the affiflance of a little fire- 
heat, which may be applied as has been already direded, p.125.
