CALCEOLARIAS. 
stopped by dusting the affected parts with sulphur, and at least 
it is always worth a trial; but the removal of sickly plants, 
especially such as are suffering from the disease named, should 
always be observed. Damp among the foliage must be carefully 
avoided, and I never use the rose on the water-pot. In March 
the principal danger will be past, and we may set about repotting ; 
in this operation it is essential that the small fibrous roots are not 
injured, and, therefore, though more than one plant may have 
been saved in each pot, they must not be separated, for the 
inevitable tearing of the roots which must follow would, beyond 
question, destroy both of them. The duplicates must either be 
cut away at once, or the two plants stationed together. The 
pots called twenty-fours, or sixteens, are about the size required 
to bloom in, and the soil should be principally loam of a sandy 
character, and further lightened with a few lumps of peat dis¬ 
tributed through it. It will be necessary to keep the plants in 
the house till the weather becomes mild, when they may be taken 
to a cold frame, and, with unremitting care in the supply of 
water, the flower-spikes may be expected to appear in July; their 
beauty will be fully developed by August, and through the 
autumn no finer object can be desired than a well-grown specimen 
of this Ipomopsis ; its light green feathery foliage enriching the 
brilliancy of its splendid scarlet blossoms.

WINTER TREATMENT OF CALCEOLARIAS. 
How to keep Calceolarias in a healthy condition from October 
to March is often a vexatious question ; they must be preserved 
over the winter, if really fine specimens are desired ; for though 
spring-sown seedlings may, with very good management, be in¬ 
duced to flower the same season, yet they have not the size 
required in plants intended for exhibition, or desired to be 
regarded as instances of good culture. Calceolarias, of the her¬ 
baceous kinds in particular, are always more impatient of a damp 
confined atmosphere, than of one several degrees colder, and, at 
the same time, dry. I have known them resist nine degrees of 
frost, but they were at the time almost devoid of moisture, and
