gentle heat in a frame, or in a shady and moist part of a green-house, taking care that, as soon as the 
plants begin to come up, they may be placed close to the glass to receive the direct influence of the 
light, shading them, at the same time, from the sun’s rays. The greatest care should be taken to 
keep the temperature and moisture as equal as possible, and to expose the tender seedlings to the 
morning and afternoon light ; but to exclude the mid-day sun. As soon as the plants have got two 
or three leaves, they should be transplanted into other pans or pots, filled with the same kind of soil, 
and shifted into pots of a larger size as soon as these are nearly filled with the roots. This process 
may be continued for two or three years, when the plants will have attained the height of from 2 ft. 
to 4 ft., accordingly as they have been kept in a higher or lower temperature. The azaleas may be 
forced forward with the heat of a stove, so as to make two, or even three, shoots in a year; but the 
rhododendrons do not so readily admit of expeditious culture. Both rhododendrons and azaleas, 
whether of the hardy or half-hardy species, force readily; and, by that process, or retardation, may 
be made to flower at any season of the year.

Spec. Char., §c. Leaves on long petioles, scattered, or 3 in a whorl, oval,

A shrub, very elegant when in flower, growing 
to the height of from 3 ft. to 10 ft.; a native 
of North America, from Canada to Carolina, 
on the sides of stony hills. It was introduced 
in 1734, and flowers in June and July. This 
shrub, in its native soil, continues flowering 
great part of the summer ; and, according to 
Kalm, forms one of the greatest ornaments of {2 
those parts of America where it is indigenous ; 
and it is only in particular places where it 
thrives ; though, according to Michaux, on (— 
the Alleghanies it occupies tracts of more \ 
than 100 acres. These are generally rocky, 
sterile, and near water. After it was intro- 
duced into England, it was for several years 
very unsuccessfully cultivated, till Mr. Peter Collinson procured some 
plants of it from Pennsylvania, where the climate being nearer to that 
of England, than either that of Carolina or Virginia, the plants obtained 
from it grew vigorously, and flowered in Mr. Catesby’s garden at Fulham, 
for the first time in England, in 1741. Leaves of this species are poisonous 
to cattle and sheep, but not to deer. The wood is very hard, and is used 
by the Indians for making spoons and other domestic utensils. Michaux 
states that, of all the American woods, that of the Kalmia latifolia the 
most nearly resembles the European box; so that it might be probably 
worth while to import it for the use of wood-engravers.
