to defend the Vines from the cold of the nights* 

 it will be necessary they should have free air in 

 the day-time, to prevent their drawing weak. 



The great damage done by oiled paper covers 

 is, from the too close covering at the beginning of 

 the season ; but when the Vines come into flower* 

 they are not so liable to receive hurt by close co- 

 vering, because the wood cannot draw weak after 

 the leaves are grown to their natural size. The 

 ripening of the grapes may be greatly accelerated 

 by covering after this period, and more especially 

 with the assistance of a little fire-heat, which maybe 

 applied as has been already directed, page L36«
