will free them from this pest, and also 
destroy scale, If the latter reappears, 
washing and sponging at intervals through 
the season will keep it down. The humid 
atmosphere. and continuous syringing 
through the season of growth will be suf- 
ficient to keep down red spider, and will 
also check greenfly and thrips, but should 
these make their appearance, fumigation 
must be resorted to. 
JASMINUM. 
(Stove. ) 
Among stove Jasmines may be found 
some of the most highly fragrant plants in 
cultivation, the perfume known as oil of 
Jasmine being procured from two or three 
of the species, such as J. grandiflorum, J. 
Sambac, and J. officinale. Among stove 
species all are favourites, but some are 
much superior to others, and to these it 
will be better to confine the following 
cultural details, which will answer for 
the shrubby and also the climbing kinds, 
with this difference, that the largest 
growers obviously want more root-room 
than the less vigorous sorts. Some of 
them furnish suitable shoots to make cut- 
tings of more freely than others, and the 
propagator should select such as are in 
proper condition for the purpose, neither 
too soft nor too hard. 
The best season to propagate is spring, 
when shoots a few inches long can be had, 
as then there is plenty of time to get the 
young plants established before winter. 
Take them off with a heel, and insert them 
thickly in small pots in sand, covered with 
a bell-glass: kept moist and shaded in a 
temperature of 70°, they will root in the 
course of a month; then, when a little 
hardened by exposure to the full air of the 
house or pit in which they have been 
struck, they should be moved into 3-inch 
pots in good fibrous loam, to which add a 
little finely-sifted rotten manure and some 
sand, giving as much water to the roots as 
is requisite to keep the soil moderately 
moist, but not over wet, as most of the 
species to which these remarks refer are 
somewhat spare-rooting plants. Keep 
them warm and in a fairly moist atmo- 
sphere, with a full complement of light, 
some air, and a little shade when the sun is 
bright. Syringe each afternoon to keep 
down red spider, by which they are liable 
to be attacked. During the middle of sum- 
mer a night temperature of 65° or 66° will 
answer, and one 10° higher by day. Dis- 
tinction will now have to be made between 
the climbing and the shrubby kinds. The 
latter will need to have the points of their 
shoots pinched out to lay the foundation 
for bushy specimens ; the former should be 
encouraged to keep to their erect habit, 
and simply be stopped when some growth 
has been made, so as to encourage as many 
shoots as required to furnish the pillar or 
rafter to which they are ultimately to be 
trained, in which way the climbing kinds 
can be grown with the best results. When 
the pots are moderately filled with roots, 
move the plants into others 3 inches larger, 
using the soil a little more lumpy, and con- 
tinue the treatment advised as to air, water, 
and heat until the autumn approaches ; then 
give more air, keep drier at the roots, and 
lower the temperature, which, during the 
last months of thé year and up to the latter 
part of February, may be about 60° in the 
night. After this gradually give more 
warmth, and as soon as the roots are in 
motion move the plants into pots 3 inches 
or 4 inches larger, continuing the treat- 
ment advised for last year in every way. 
By midsummer it should be determined 
how the climbing sorts are to be grown ; 
the weaker growers, such as J. Sambac, are 
as well with their roots kept in pots, in- 
creasing the size as more room is required ; 
the bushy kinds need to be similarly 
treated in this matter, and care should be 
taken not to over-pot them, as they will 
succeed better with less root-space than 
many plants. If this treatment is continued 
they will last for years; each spring as 
much of the surface soil as can be got away 
without materially interfering with the 
roots should be removed and replaced with 
new. Clear manure-water, given at short 
intervals through the growing season, will 
help the growth, which it is necessary to 
encourage, as the flower forthcoming with 
these plants is generally proportionate to 
the wood they make. We have found the 
time of blooming with the stove species of 
Jasmine very much consequent on the 
amount of heat they are subjected to. 
The undermentioned we consider the 
best, taking all properties into considera- 
tion :— 
J. Duchesse @Orleans. A climbing or 
tall-crowing kind that has originated on 
the Continent, with very handsome white 
flowers, which keep on opening in succes- 
sion, so long as any growth is being made. 
It likes a brisk heat. 
J. gracile. A plant of slender habit, 
from Norfolk Island ; it has white flowers, 
and will grow in a lower temperature than 
the others named. 
J. gracile variegatum. A form of J. gracile, 
from which it differs in being variegated. 
J. gracillimum. A new and beautiful 
species with white, sweet-scented flowers,
