currant, are generally infested with this glutinous 
substance, while the rhododendrons, laurels, and 
many other plants, ai-e never at all aiuioyed. Here 
I am reminded, that when walking along’ the side 
of a plantation which stretched its branches over 
the causeway, I suddenly cast my eye upon a portion 
of the causeway that was spotted over as though 
a gentle shower of rain had commenced, but on 
looking up nothing like rain appeai’ed j while 
gazing I was not long at a loss in finding out the 
cloud from whence this dew had issued, for imme- 
diately over me were the sycamore branches in- 
habited by myriads of these animals, and for the 
whole length of the plantation 1 had no need to 
look up to find the sycamore, for under the 
whole, as they came in rotation, the above marks 
were exhibited. Plants even when protected by 
glass, become covered with this sacchaiine fluid; 
but if it were produced from the heavens, it would 
be impossible to suppose that it would fall through 
the glass and light on the plants. If the Honey 
Fall is produced from the perspiration of some pai’t 
of the tree, as Millar and others assert, one 
would naturally suppose the Aphides would be 
found on the upper surface of the leaves where this 
fluid generally apjiears, a circumstance which 
never happens except by single insects travelling- 
in search of a proper station. Their habitation^ 
are chiefly on the underside of the leaves, or upon 
the ends of the young shoots where the Honey 
Fall is seldom to be found, or at least to no great
