temperature so that any sudden transition from it must be in¬ 
jurious either from exciting or repelling Causes; and having 
spoken of the last, we will endeavour to explain or point out 
the opposite danger, that of too sudden exposure to the sun’s 
rays. In this case the plant being predisposed from its confine¬ 
ment to the production of sap, on being exposed to the exciting 
influence of the sun immediately proceeds to the elaboration of 
more fluid, and in a very short time is surcharged at all points ; 
in this state it is probably again covered up, and from the pre¬ 
sence of so much aqueous matter a chill, if we may so speak, 
strikes through its entire frame, and if the subsequent weather 
happens to be severe, such sap being crude and ill digested 
becomes frozen, thus proving the cause, of the effect before de¬ 
scribed; so that the covering which may have been continued 
for any length of time, should be removed at short intervals, and 
by gentle degrees, always using the precaution of slightly shading 
the plants when first uncovered ; and this precaution is very ne¬ 
cessary when any plant, either in the open air or under glass 
has happened to get frosted, and should be continued until it 
is thawed, for the sun acting upon the thin coating of ice spread 
over the leaves of the plant, acquires nearly as much force as 
though shining through a lens; the effect of this was fully shown 
by our respected correspondent Mr. Hally in his article on 
Camellia, to which we refer. If a slight frost chance to enter 
the greenhouse, some advantage may be gained by syringing 
the plants with cold water before the sun is upon them, and 
afterwards shading the house until the plants are dry, which 
may be hastened by fire heat. ' Editor. 
ON SUSPENDING PLANTS. 
Sir,-— Allow me to offer a few remarks on this method of 
ornamenting plant structures. I have many times been struck 
with the awkward appearance of trailing plants when fastened in 
an upright position to sticks or trellis ; it has a strained and un¬ 
natural look, when the same plants by the application of a little
