& pity we do not see more of this fine Orchid, which, 
ing, is smothered out of existence in 
air, a clear light and plenty of 
when growing are the chief essentials. 
The warm-house plants are in keeping with the 
of Vanda Parishii raised up on a stout stem and still 
carrying its leaves down to the pot. А variety of 
Dendrobium chrysotoxum also had flowers twice the 
usual size, D. Jamesianum was profusely flowered, 
and various other Dendrobes, P &c., in 
bloom. When Orchids are grown and flowered as 
with Mr. Haywood, no class of plants can Mifare 
them, to say the least of it. J. 
FERTILISATION OF DISA

diptera haunt the dope of the mountain—of

P. varicolor, which Mrs. Barber informs me is instru-

district.

It is now a good time to sow seeds; the plants from

sets in. It is best to sow seed on a sheltered border 
out-of-doors; when the young plants have grown 
large enough, prick them out about 9 iches apart, 
and when they have grown into sturdy well-leaved 
plants they may be planted where they are to flower

It is now a good time to sow seeds of this plant, 
if good large specimens are required, such as were 
exhibited by Mr. J. James a 
after-treatment of the plants have been frequently 
described. Any very good varieties may be pro- 
pagated by a process of layering, which is more certain 
than taking cuttings. hen the flower-stems have 
been removed the plants may be placed in a frame, 
and some fine sandy mould should be placed over the 
seedling plants, but they make handsome specimens,

Presidents and Paxtons (a huge stock, and in splendid 
“trim” at the time of our visit) are grown for out- 
door eulture; the latter is os invaluable for 
this purpose. The culture is not confined to pot 
Strawberries, for in long ran nr low frames we 
observed hundreds of fine plants laden with fruit that 
were last year forced in pots, planted out, and in 
early spring protected and planted in rows 18 inches 
apart in these frames

good promise of a full fruiting season, the bed at the

that this will be the best Strawberry season у 
had for years.
