month look over them all minutely, and cut away any of the 
small naked wood where it is too crowded, and cut all young 
strong straggling shoots to the bounds of the tree, giving it 
a round regular head. It is sometimes necessary to cut out 
a small limb, but large amputations should be avoided. 
Cover all large wounds with clay, turpentine, or beeswax, to 
prevent the bad effects of the air. 
OF REPOTTING PLANTS. 
Any of the plants enumerated in March under this head 
may be now done according to directions therein given, and 
which apply to all sizes. This is the proper period for repot- 
ting the following : 
Calla, a genus of four species. None of them in our col- 
lections, and in fact not worth cultivation, except G. jEtlii- 
opica, Ethiopian Lily, which is admired for the purity and 
singularity of its large white flowers, or rather spatha, which is 
cucullate, leaves sagittate. It is now called Richard ia JEthi- 
opica. The roots, which are tubers, should be entirely 
divested of the soil they have been grown in, breaking off any 
small offsets, and potting them wholly in fresh earth. When 
growing, they cannot get too much water. The plant will 
grow in a pond of water, and withstand our severest winters, 
provided the roots are kept at the bottom of the water. 
Cyclamen. There are eight species and six varieties of 
this genus, which consists of humble plants with very beau- 
tiful flowers. The bulbs are round, flattened, and solid, and 
are peculiarly adapted for pots and the decorating of rooms. 
G. cbum, leaves almost round ; flowers light red ; in bloom 
from January to April. C. persicum, with its four varieties, 
flower from January to April ; colour white, and some white 
and purple. G. heeler aefolium, Ivy-leaved ; colour lilac ; 
there is a white variety ; flowers from September to De- 
cember. G. Europaeum, colour lilac, in bloom from August 
to October. G. NeapoUtanum, flowers red ; in bloom from 
July to September. These are all desirable plants. When 
the foliage begins to decay, withhold the accustomed sup- 
plies of water, keeping them in a half dry state ; and, when 
growing, they must not be over-watered, as they are apt- to
