when, by easing itself from its bed, the fluid passes under 
it, and causes immediate death. If it is not thus irritated, 
it adheres so closely to the foliage that it will keep you at 
defiance. The under or dark side of the leaves is its resi- 
dence j and we have observed a plant in a house where there 
was only light on one side, with the dark side literally 
covered, while the light side was clean. So much for having 
houses with plenty of light. The effects of this insect are 
of a corroding nature, extracting all the juice from the leaf; 
and where they have got to the extremity, the foliage is 
completely yellow, and of a decayed appearance. 
Corns , or turtle insect. We have never ob- 
served this insect arrive to any extent. It is the largest of 
any known among us, and very like a turtle in minia- 
ture. On lifting it from the wood, to which it generally 
adheres, there appear to be hundreds of eggs under it, but 
fumigating completely destroys the larvge. In our opinion, 
this turtle insect is no other than the old female of the 
brown scaly insect, which swells to a large size befoi-e de- 
positing its eggs. We have frequently observed the insect 
dead in this enlarged state, and question if this be not the 
last stage of its transmigration. The male insect is winged, 
and very active in its movements. 
Where bulbous roots, such as Hyacinths, Jonquils, Ixias, 
Lachendllas, &c, are required to be early in flower, they 
may, during this month, be put in the front of the hot- 
house and watered freely till they bloom, when they may be 
taken to the green-house or parlour. 
Azaleas, Rhododendron Roses, and some other plants, do 
admirably to force ; and where there is a large stock, a few 
should be brought into early bloom with the heat of this 
department. 
OF CLEANSING PLANTS, HOUSE, ETC. 
This subject ought to be kept constantly in view. How- 
ever correctly everything else may be executed, without 
that adorning beauty, cleanliness, all will appear only half 
done. Therefore let all the dead leaves be picked off every 
day, the dust and other litter swept out of the house, and, 
when necessary, the house washed, which will be at least
