X. — Your seedling Picotee is too small altogether. 
Florista. — The late rains have so far injured the flowers sent, that 
we deem it unfair to give an opinion of them in their present state — send 
again. 
A box of Petunia blooms have reached us, without name or address; of 
these, only No. 6. is worth keeping — but that is very good. We cannot 
describe it without having the name of the party who sent it. 
CALENDAR FOR SEPTEMBER. 
Plant Stove. The application of artificial heat, in sufficient 
quantity to render it appreciable, is still more important, it pos¬ 
sible, noiu, than in the depth of winter. Hot autumnal days are 
generally succeeded by nights very much cooler than what 
would be proportionate to the heat of the day; and when the 
external temperature is thus disproportionately lowered, that 
which is internal is affected also, and considerable injur}' is sus¬ 
tained by such plants as have not matured their growth. Those 
which have naturally gone into a state of rest will be less sen¬ 
sible of this declension of heat. It is in many cases necessary 
to extend the growing season over a portion of the autumnal 
months, in order to secure an average increase of growth ; and 
this treatment, which involves the attention we now refer to, to 
render it successful, is often preferable to the premature arrest 
of this growth, ere it becomes satisfactory and complete. In 
applying Beat at this season, however, we must not forget for 
what it is applied: this is simply to mature late growth, and by 
no means to excite renewed development; it must, therefore, 
be accompanied by a small proportion of moisture, and be 
powerful in proportion as it is accompanied by light. 
Greenhouse.- The protection of greenhouse plants from 
heavy and continued rains, and from frost, and the preparation 
of them for their winter-quarters, will now require strict and 
punctual attention. The most delicate should be first secured, 
and then the others may follow, as opportunity or necessity may 
suggest. It is essential that when first removed under shelter, 
they should be allowed to remain as open as possible, or the 
confined dampness of the atmosphere will cause the succulent 
scarcely-ripened shoots to damp off. The amateur should im¬ 
press on his mind that the least degree of protection which 
excludes frost is sufficient for the majority of these plants, and 
far preferable than a more powerful application, which frequently
