many of them perish ; by this means they are easily checked. 



Green-fly, — This, like the preceding one, in fa6l like 

 all this class of inse6ls, — namely Plant-lice, Green-fly, 

 Aphides &c. — prefers to feed on the soft tender parts 

 of plants, rather than on the harder or more woody 

 parts. Hence it is invariably found to live on herbaceous 

 plants and the young growth of the more woody plants^ 



The fumes of tobacco smoke, as well as water highly 

 impregnated with this powerful narcotic, is a most 

 effectual remedy for this inse6l. The latter should be 

 well mixed, and syringed on the foliage. Soap water 

 might be employed in the same way. If proper attention 

 were paid to syringing plants, the ravages of this inseft, 

 as well as of others, would be very trifling ; but, unfortu- 

 nately, no branch of culture is less attended to than this. 



Caterpillars. — Great damage is often done by caterpil- 

 lars to our most valuedplants; maiden-hair ferns suffer par- 

 ticularly from their rapacious attacks, but I mention them 

 here particularly on account of the trouble they have lately 

 given in raising seedling canes. The minute caterpillar of 

 some minute moth, almost at soon as the cane-seeds have 

 germinated, preys upon the seedlings, and it is only with 

 the keenest sight, by careful watching, and continual pick- 

 ing and destroying of the depredators, that one is able to 

 save the better sorts. 



Crickets and Locusts are also destruftive to many kinds 

 of plants and flowers. The flowers of Orchids and Eucharis 

 lily are often destroyed by them as soon as they appear. They 

 are also troublesome to the larger and most forward of 

 the cane seedlings. 



After this predatory crowd I may mention Ants which 

 are said to eat, and help to keep down, Aphides and other
