remembrance in their searches ; and, when their object is to obtain plants adapted 
to the climate of the countries for which they are travelling, they should endeavour 
to procure the seeds from those localities, the temperature of which accords most 
nearly with that of their own clime. 
There is another office performed by heat in maturing fruit, to which it may 
be well briefly to allude. It has already been asserted to be the prime cause of 
fertility ; but, with pulpy and edible fruits, it is also the main agent in rendering 
them palatable and agreeable. All saccharine matter is generated by the action 
of heat, as is proved by the acidity of those fruits which are produced in cold 
summers, or are insufficiently ripened. It may be assumed, likewise, that though 
sugar is so abundantly manufactured from tlie beet-root in France, a remunerative, 
or at least an equal, return could not be realized in England, even though the 
price of land and of labour were assimilated.

ON THE TREATMENT OF GREENHOUSE CLIMBING PLANTS, 
AS ORNAMENTS TO PLEASURE-GROUNDS. 
Among the numerous alterations introduced by modern taste and science into 
the disposition and arrangements of the ornate department of a garden, none is 
better entitled to be called an improvement than that of transferring tender 
exotics to the external beds or borders during a few of the more favourable summer 
months. Exhibiting in general a more graceful character than hardy kinds, there 
is besides a peculiar charm connected with the appearance of a plant luxuriating 
unreservedly in the open ground and air, which is well known to belong to a dis- 
tant and much warmef climate, and to be usually cultivated in our greenhouses. 
A feeling of delight pervades the mind when such an object is presented to view, 
which it is almost impossible to delineate or define, but which, we are sure, is par- 
ticipated or experienced by all whose perceptions are in any degree influenced by 
extrinsic associations. 
Self gratulation is very naturally awakened in the human breast on the accom- 
plishment of any object hitherto deemed impracticable, or so unlooked for as never 
to have excited attention or thought. And perhaps in no instance is this emotion more 
innocent,"or less sullied by ignoble promptings, than when occasioned by the simple, 
yet, if fathomed aright, intensely profound pleasure, derivable from the superior or 
novel and successful treatment of any scarce or favourite plant. Nor do we think 
but that amor patricB^ so characteristic of Britons, must glow more warmly when 
witnessing the capability of their beloved isle to sustain the vegetable productions 
of far more genial regions. 
No situation can be conceived which would be more talismanic in its effect 
upon an enlightened and sensitive mind than a prospect on British ground bedecked
