IIONEY-DEW, AND BLIGHTS. 327 



up the pores, and stops the perspiration of trees, it 

 must of course be very hurtful to them. This 

 disease should be treated in the same manner as

 trees should be watered, or washed, early enough 

 in the day to get dry before the cold of the night 

 comes on j nor should it be done while the sun 

 shines very hot, which would be likely to scorch 

 the blossoms and leaves. 



Of Blights, 



Blights are very destructive to fruit-trees, some- 

 times destroying the whole tree ; but more fre- 

 quently the leaves and blossoms, while the tree it- 

 self remains unhurt. 



One cause of the blight is, the continuance of 

 a dry easterly wind for several days together, 

 which stops the perspiration in the tender blos- 

 som ; and a long continuance of the same wea- 

 ther equally affects the tender leaves, causing 

 them to wither and decay ; the perspiring mat- 

 ter is thereby rendered thick and glutinous, and 

 so becomes food for those small insects which 

 are always found in vast numbers on fruit-trees 

 that are affected by this sort of blight. 



These insects, however, are not the original 

 cause, as some imagine, but the natural conse- 

 quence of blights ; for wherever they meet with 

 such a proper nutriment they multiply amazingly,
