[ Correspondents, please note that we cannot undertake to 
name florists' flowers such as Carnations, Pelargoniums , 
Chrysanthemums, Roses, nor such as are mere garden 
varieties, differing only in the colour’of the flower. 
Florists' flowers, as a rule, can only be named by those who 
grow collections of them.] 
Apple Mussel Scale.— A. G. B : The present is 
the bes time fur UDdmakiog operations against th^ 
Apple Mussel Scale (Mytilaspis pomorum), while the 
trees are bare of leaves. Various preparations are 
used, and a good one lor this class of insects out of 
doors is 9 lbs. of resin, lbs. of caustic soda (70 
per cert strength), fish oil, pints, and water to 
make the total amount up to 50 gallons. The way 
to prepare this mixture is to put the resiD, caustic 
soda, and fish oil into a kettle, with sufficient water 
to cover the whole. Get the water to boil till the 
materials are dissolved, and while this is being 
brought about the contents must be stirred. After 
the materials are dissolved boil them briskly for an 
hour, taking care not to let the mixture boil over by 
dropping a little cold water into the kettle when that 
is likely to happen, without taking it off the boil. 
After the process has gone on for an hour, boiling 
being continued all the time, then cold water must 
be added to bring the whole up to 50 gallons. The 
preparation will then readily mix with water. Before 
using the mixture it should be strained through a 
wire sieve or piece of muslin to remove impurities 
that would choke the syringe or spray. Make every 
part of the tree, but especially the rough bark of the 
trunk, quite wet, driving the spray with some force 
into the crevices. 
Chrysanthemum Leaf Miner in Winter.— PI. C.: 
The fact of this little enemy being at work just now 
indicates that the temperature of the house in which 
you grow the Marguerites is sufficiently high to 
ba ch out the pupae. There are several broods in 
the course of a season, the number being dependent 
upon the temperature. If the pupae were out of 
doors the cold weather would compel them to 
remain dormant till spring. Soon after being 
hatched out the females set about laying their eggs, 
and the latter soon hatch out if the temperature is 
sufficiently high. The young grubs then commence 
burrowing operations. The present is, however, 
the best time for exterminating all that make their 
appearance under glass. The worst of the leaves 
should be removed and burnt, the rest being 
squeezed between the finger and thumb, so as to 
crush the grubs in them. The lower side of the leaf 
will show where to find the grubs or pupae. Syringe 
the plants about every ten days with tobacco water, 
so as to drive away the female flies and prevent their 
laying their eees upon the foliage. 
Propag'ating the Strawberry Tree.— Ch M. : 
This snruu can De propagneU Dy seeds, layers, cut¬ 
tings in sandy soil, and by grafting. Plants raised 
from cuttings would take a long time to reach the 
flowering stage as compared with those of the other 
methods mentioned. Grafting is only necessary in 
order to increase and perpetuate varieties, such as 
Arbutus Ucedo rubra. There remain the two 
ready methods of increase by layers and cuttings. 
Provided you can get shoots near enough to the soil 
you could prepare a peaty bed for them and layer 
them. Cut a notch or tongue at the place where you 
can bring the shoot in contact with the soil; peg it 
down and cover with the soil. By this time next 
year, or a little later on in the spring, the layers 
should be ready for removal and planting in nursery 
lines. 
Black Currants with Swollen Buds.— T. B. H. : 
The swollen buds a e tn> se of the Currant Mite 
(Phytoptus Ribis). Carefully pick off and burn 
every bud showing undoubted signs of unnatural 
swelling. In the case of badly inlested shoots the 
better and quicker plan would be to cut off and burn 
them. When whole bu hes are very bad, the best 
plan would be to grub them up and make a fresh 
plantation The plantation might be got partly into 
bearing before the old is destroyed to furnish a 
supply of fruit. 
Raising New Varieties of Aucuba — A .L W. : The 
usual metnod adopted is to co lect the berries when 
they are ripe, and sow them rather thickly in beds. 
This should be done as soon as the berries are ripe, 
as the seedlings require some little time to germinate. 
If you already have some distinct varieties, there 
will be the greater chance of getting something 
gcod. The variations are chiefly confined to the 
variegation, but there is a variety with long, narrow 
leaves, namely, Aucuba japonica longifolia. There 
is also A. himalaica, a species with narrower leaves 
and rounder berries than the better known species 
from Japan. You could intercross the varieties of 
A. japonica, or hybridise it with A. himalaica For 
the convenience of this operation, you shtu’.d 
put plants into pots, and bring them into bloom in a 
pit, greenhouse or other structure, with a temnera- 
ture of forty-five degrees or thereby, and a relatively 
dry atmosphere. Collect the pollen from the male 
flowers with a camel hair pencil, and apply it to the 
stigmas of the female flowers when fully developed. 
If these are not open, you can keep the pollen for 
two or three weeks between two pieces of glass kept 
dry.

The flow of Sap.—It is a mistake to thick that sap 
flows upward through the whole stem of a tree. The 
region of up currents is In the youeger portion of the 
wood nearest the bark. The central heart-wood is 
dead, at least, it is hardened and dry, remaining 
sound of course for greater or less periods of time. 
No worm or other vermin can possibly enter a plant where 
Porter’s Patent Invincible Crooks 
are used. Neither boards, slates, nor ashes are required to 
stand the pots on, so that money, time, and injury to plants 
are saved; they .fit any pot, and last for many years. All 
Chrysanthemum growers should use them
