it is opened, the more successful will be the result. It neither i is, nor is 
intended to be, perfectly air-tight; the whole being glazed as a green- 
house. That glass answers best which is ited flatted crown glass. 
The plants which require much humidity are to be planted i in the soil 
of the box, those which need less may be suspended, in pots containing 
sand, from the roof of the case. Plants which vegetate in very warm 
climates, and exogenous plants generally, should be placed at a win- 
dow facing the south. ‘Ferns, and similar plants, do well enough before 
one with a northern exposure. 
The prime causes of the difficulty of growing plants in large cities 
are the excessive evaporation to which they are subjected in poe, and 
the deleterious effects which the products of combustion, disseminated 
in the atmosphere, produce upon them. But by this ingenious plan 
these obstacles are removed, and plants have grown in some of Mr. 
Ward's cases, flowered and ripened fruit, without receiving a fresh 
supply of water for several years. Its utility, in facilitating the trans- 
mission of plants from remote regions, has been abundantly proved, 
and its value becomes obvious when the difficulties formerly expe- 
rienced are considered. The beneficial results likely to follow a more 
extended adoption of this plan cannot be estimated at present, but 
even already the number of new plants thus introduced into our stoves 
testify its importance. Nor is it possible to estimate too highly 
the effects which it will have in increasing the pleasures and enjoy- 
ments of the inhabitants of towns, by enabling them to adorn their 
rooms with the most beautiful and tender plants. It is not necessary 
to build a fine or expensive case, such as that above described, to 
carry it into practice: a large wide-mouthed bottle, with a proper 
quantity of moist earth, closed with a portion of bladder or thin india- 
rubber, will answer well, and in such have we seen a beautiful speci- 
men of Chorozema cordatum growing, in Mr. Ward’ Thus 
the poorest as well as the wealthiest denizens of our cities may gratify 
their taste for flowers, and have their care repaid more thoroughly 
than it ever was before. Cowper, who ‘mid a faithless generation was 
found faithful to the love of nature, has observed that the relish for 
the beautiful works of the Creator
