328 OF THE MILDEW, 



and greatly promote the distemper when no method 

 is taken to prevent it. 



The best remedy for this distemper that I know 

 of is, to wash them with urine and soapsuds, as 

 before directed ; and the sooner this is performed, 

 whenever we apprehend danger, the better : if the 

 young and tender shoots seem to be much infect- 

 ed, wash them with a woollen cloth dipped in 

 the same liquid that is recommended for the mil- 

 dew. 



Another cause of blights in the Spring will be 

 found in sharp hoary frosts, which are often suc- 

 ceeded by hot sunshine in the day-time ; these are 

 certain and sudden destruction to the fruit. Sharp 

 pinching frosty mornings, which often happen 

 when the trees are in flower, or while the fruit is 

 very young, occasion the blossoms or fruit to drop 

 off, and sometimes greatly injure the tender shoots 

 and leaves. 



The only method yet found out to prevent this 

 mischief is, the carefully covering the walls with 

 netting, &c. as before directed. * The covering 

 is to remain on during the night, and to be taken 

 off in the day time. This method has been rec- 

 koned of little service by some, which, indeed, may 

 be the case when the coverings are not properly 

 used ; for, if the trees are kept too long covered, 

 the young branches and leaves will be so weak as 

 not to be able to bear the open air when they are 

 exposed to it.
