the stems. The flowers are pro- | 
duced in autumn, and the plants 
require a light rich soil.

Leprtosi\pHon.—Polemoniaicee.— 
retty Californian annuals, nearly 
allied to Gilia, which will bear a/|

see ANNUALS. 
Leprosre’rmuM. — Myrtécee. — | 
Very pretty Australian half-hardy 
shrubs, with white flowers, which | 
are generally kept in a greenhouse | 
in England, but which may be| 
grown in the open air, with a shght 
protection during ~ winter. hey | 
require a sandy loam mixed with 
peat in nearly equal quantities: and | 
they are generatly propagated by 
cuttings, as the plants which are | 
raised from seed are a long time be- | 
fore they flower. | 
Lespepe’za. — Legumindse. — | 
ea-flowered perennial plants, near- | 
ly allied to the French Honeysuckle ; 
which only require to be planted 1 in | 
any common garden soil, in the |

only require a slight protection in 
England during winter.

of the new genera into which Pro- 
fessor Don has divided the genus 
Erica. 
LEVELLING is an operation which 
is required on a large scale in lay- 
ing out gardens, and on a smaller 
scale in digging uneven ground. In 
either case, care should be taken 
to keep the best soil on the surface, 
so that when a hill is to be lowered 
in order-to fill up a hollow, the first 
operation is to take off the surface 
of both, and reduce the ground to 
a uniform inclination or level, by 
removing the subsoil; and replacing 
the surface soil afterward evenly 
over the whole. In practice it is 
_seldom, if ever, desirable to reduce 
a surface to a perfect level, because 
in that case the rain which fell on 
it would not readily run off. An 
inclination should generally be given 
from one side to the other; or, 
when the plot is a square, from the 
centre to all the sides; and this ia- 
clination may be so gentle as to 
render it quite impossible to be de- 
tected by the eye alone. A piece 
| of ground filty feet broad may have 
an inclination of three inches, if the 
_ soil be loamy and retentive; but if 
it be sandy and absorbent, an inch 
and a half will be sufficient. In 
levelling lawns, no part whatever 
of the surface ought to be on what 
lled a dead, or perfect level ; 
e as the grass retains the

and Jab alee the same treatment, |on during the whole of the winter 
| and spring.. All flat lawns, there-
