But if water be artificially heated, in order to elevate it to a proper degree of 
temperature, the air it contains is expelled by the heat. In supplying such water 
to plants, it it advisable to restore the air it has lost, to render it fit for imbibition by 
the delicate pores of plants. This can easily be done by distributing it to them 
through a syringe or engine ; by which means it will be mixed with a quantity of 
air. This is a remark of some moment, and by no means a superfluous refine- 
ment, if we consider how dainty a delicate plant is with respect to moisture and air. 
ON TRAINING ROSES, AND OTHER CLIMBING PLANTS, 
TO POLES. 
Of the many diversified forms and modes of growth which plants exhibit, the 
climbing or twining habit would seem to be the most graceful and interesting. As 
man is accustomed to regard more tenderly and fervently such objects as depend 
upon, or, as it were, cling to, him for protection and support ; so, in the vegetable 
world, those plants appear to excite the greatest interest which require the assist- 
ance of their more robust neighbours to maintain them in their needful position, 
and uphold them from grovelling prostration. We will not say that the mere 
presentation to the mind of any object in dependent circumstances necessarily 
awakens sympathy and attachment, but that it is a powerful incentive to those 
feelings, and especially when associated with delicacy and beauty, every one will 
be prepared to admit : and whether from this peculiarity in human nature, or from 
pure admiration of their delightful wreathing and fantastic contortion, we have 
always observed that climbing plants are acknowledged favourites with persons of 
refined taste and sensitive minds. 
Their sprightly and elegant disposition, the enchanting irregularity and negli- 
gence with which their branches are arranged and entangled, and the beautiful 
manner in which the extremities of these protrude and depend so as best to exhibit 
their varied blossoms, each contribute to heighten their attractions and invest them 
with increased powers of captivation. We allude chiefly to their appearance in a 
natural state, for when subjected to artificial cultivation, the operations of training 
and pruning deprive them of much of that pleasing simplicity which intrinsically 
characterizes them, and which is the principal cause of our attachment. 
It is much to be regretted that the unnatural method of training these plants 
to walls or trellises should be so generally substituted for that which nature 
teaches us is the most graceful and ornamental, and by far the best adapted to the 
purpose of displaying their peculiar habits and beauties — supporting them by poles or 
the stems of trees. We are far from wishing the former of these modes discontinued 
or abated, as it constitutes an agreeable variety, and frequently secures an orna- 
ment to what would otherwise be an unsightly surface ; we would only urge the
