Bark, or Moist Stove.—A plant 
structure with a glass roof, and a 
bed or pit in its centre, containing 
a mass of fermenting matter, or of | 
earth or sand, heated by artificial 
means, in which plants in pots are 
to be plunged. The plants grown 
in such houses being natives of the 
warmest parts of tropical countries, 
the temperature in a_ bark-stove 
should never be lower than 60°, and 
during summer it may rise as high 
as 80 or 96°. In general, the heat 
ought to be greatest in the day-time, | 
and during bright sunshine, and 
least during night, throughout the 
year. 
house with suificient moisture, the 
floors of the passages should be 
frequently watered; and to facili. 
tate the same object, and to sub- | 
due insects, the plants should be | 
syringed or watered overhead, most 
days in the year, and especially in 
the summer season, about three 
o’clock in the afternoon. After this 
watering the house should be shut 
up for the night; excepting when 
the weather is very warm, when 
some air may be given by opening 
the sashes at eight or nine o’clock 
at night, and leaving them open till 
the following morning, at six or| 
seven. Independently of the bark- |

Barto'nia.—-Loasdcee.—-B. aurea 
is a new and splendid annual, with 
golden yellow flowers, whieh have 
/quite a metallic lustre when the 
sun shines upon them. The seed- 
pod is curiously twisted. Like all 
the Californian annuals, it is very 
apt to die off if the roots become 
at all withered by drought, or if the 
collar of the plant be exposed to 
the full heat of the sun; and it 
thus does best when grown in 
masses, so that the ground may be 
quite covered with its leaves. B. 
albéscens has greenish white flow- 
ers, and is not worth growing.

tuberdsa, the Madeira vime, is a 
beautiful climbing plant recently 
introduced, which, from the elegance 
of its glossy foliage, and its numer- 
ous frazrant white flowers, has al- 
ready become quite a favorite. It 
grows with the greatest ease in any 
soil, but in a mich loam, it will grow 
forty feet in a single seaseon—and is 
therefore an admirable plant for 
covering an arbour or screen where 
immediate effect is desired. The 
roots are tuberous, with numerous 
eyes or buds somewhat resembling 
the potato, and may be kept through 
the winter in a warm cellar in the 
same manner.—Ep.} 
Bast, or Bass.——The inner bark 
of the lime-tree, separated by steep- 
ing the bark in water till it can be 
readily pulled asunder into ribands, 
or strands ; these are hung up for 
some months in thejshade, and they 
are then woven into mats. The 
manufacture of these mats is con- 
fined to Russia and some parts of 
Sweden, where the name for bark 
is bast.
