ON THE INFLUENCE OF CLIMATE ON PLANTS. 
whenever we recommend cultivators to allow a plant an abundance of pot room, 
We mean, that it should be frequently and gradually shifted into pots of a larger 
size, as its growth may require, till it either attains its proper height and size, or 
till further shifting appears unnecessary. "With regard to the subject of the pre- 
sent article, we would suggest, that, instead of keeping it in pots, which must 
necessarily check its growth, it should be planted in a prepared compost in the bed 
or border in the interior of a greenhouse or conservatory, where we have not the 
slightest doubt it would form a most handsome and attractive object. In this sug- 
gestion we are borne out by the experience of many cultivators who have grown 
this plant in the open ground, as it has invariably grown more vigorously when 
thus treated than when kept in a pot. Besides the prevailing erroneous practices 
in the particulars of soil and potting already noticed, there are few cultivators who 
allow this plant a sufficient quantity of water to the roots, and still fewer who 
occasionally apply water to the leaves and branches with a syringe. The former 
of these operations must strike every intelligent cultivator as absolutely essential to 
a plant of such luxuriant habits, but the latter, experience alone has taught to be 
necessary ; for, unless particular attention is paid to it, or the atmosphere of the 
house is kept slightly humid, (which is almost impracticable in the greenhouse,) 
this plant is frequently attacked by the red spider, and its beautiful green foliage 
rendered yellow and unsightly. 
In concluding these somewhat lengthened remarks upon a plant, which it must 
be allowed possesses more than ordinary interest, we would especially beg the 
attention of our readers to our proposition with respect to planting the CliantJms 
in a border in the greenhouse ; as by this system the evils attendant upon in- 
sufficient pot room would at once be obviated, and there would be little danger of 
the plant suffering for want of water. We may add, that, although it is not 
capable of enduring severe weather in the open air, it may be safely kept in a cold 
frame that is well protected, as we are assured by a respectable correspondent that 
it remained during the whole of the late winter in a pot in a cold vinery without 
losing a leaflet, and though from one to three degrees of frost occurred several 
times in the house, it did not sustain the slightest injury.

Every individual who possesses any knowledge of the habits and appetences 
of the members of the vegetable kingdom, or who has exerted himself in the 
slightest degree to ascertain and investigate the various relations subsisting between 
plants and the atmosphere, must be aware that the elements constituting that 
atmosphere, and which operate upon plants through its medium, exercise a most
