the atmosphere is rendered moist by the exhalations from an adjacent river, an 
other extensive bodies of water ; and that the same plants which require all th 
attention here, may be managed with much less in more genial places. Henci| 
other plants also, which would not exist through the winter upon a wall ii 
Derbyshire, may stand and flourish in warmer localities. 
Several plants, moreover, which are usually considered insufiiciently hardj 
have been found to stand here, without other protection than that of a wall. I 
conclusion, therefore, we would suggest to those who have not convenience fc 
erecting a wall expressly for the conservation of exotics, to appropriate the wall 
of any naked building to the purpose. The walls of a dwelling-house will be ^ 
sufiicient shield for many beautiful things that are too delicate to endure the ope! 
garden. Thus the cottager as well as the peer may have his conservative wall 
and cultivate a number of plants that would otherwise be placed without hi 
reach. |

CULTURAL HINTS. 
In resuming our remarks under this head we fasten on another circumstance 
which, like the last, appears to be ranked amongst the matters which are usuall; 
denominated “ trifles ” by careless cultivators. ~ 
When speaking of the disadvantages accruing to plants through exposing th| 
pots to the sun, we made a passing allusion to the injury inflicted on greenhous 
plants that have been plunged amongst ashes to protect them, by the roots passin| 
through the aperture in the bottom of the pot, establishing themselves in the ashe 
or earth beneath, and thereby causing the necessity for a considerable disrootin| 
at the period of removal to their winter quarters. As this evil exists to a degrei 
productive of much debilitation and loss of beauty, we now return to the subject! 
with the view of pointing out the best means of preventing its recurrence, or a| 
least to diminish largely the chances of pernicious effects resulting. 
The mode in which the potting of plants is executed, exercises an influence oi 
the protrusion of roots through the bottom of the pot into the substance beneath, > 
It is clear that when a large quantity of roots are left near the bottom at the 
time of potting, their extrusion will be accelerated,' especially as the lower 
roots are always the most vigorous ; and in those plants that naturally make 
strong roots with few lateral ramifications, the evil will be still more obvious, 
Deep planting and deep potting are indeed generally recognised amongst the 
evidences of an ignorant or thoughtless cultivator ; but even those who acknow- 
ledge their impropriety frequently content themselves with merely raising the ball,| 
or observing not to bury more of the stem than was covered at the previous potting 
or planting. Now this is but a very partial way of adhering to the maxim olj 
shallow planting ; for the intention of planting high is to keep the roots near theii
