DECEMBER, 1907-| THE ORCHID REVIEW. 359 
were soon in evidence. Theplants were then shaken out, and potted in a 
mixture of two-thirds loam and one-third peat, with plenty of sand and 
small crocks. Ordinary pots were used, and they were placed on the 
stage in the Cool intermediate house till the roots and growth had made 
good progress. They were then only watered when quite dry, but afterwards 
the supply was increased, and during the time when the new bulb was 
developing they were never allowed to become anywhere near dry. As soon 
as they showed signs of leaf-decay we removed them to a house where 
much air and direct sunshine reached them, gradually reducing the supply 
of water till all the foliage was gone. From then till the flower buds were 
in evidence they were kept quite dry, in fact, I do not know if it is even 
necessary to give any water when they are developing their flower buds. 
For flowering they should be placed in a light position, where the tempera- 
ture does not fall below 55°. I believe it will be found all important that 
this species should be given plenty of material in which to root. Very little 
drainage will be required, providing they are carefully watered just after 
the potting, which should be an annual process, the whole growth of the 
plants indicating that they require a good retentive compost, and plenty of 
it. With liberal culture I believe they will soon increase, but should say that 
if they are grown suspended in shallow receptacles they would soon» 
deteriorate. 
STENOGLOTTIS LONGIFOLIA.—Although the individual flowers are small, 
fine spikes of this Cool house Orchid are very decorative, and as they flower 
from the end of October till well on into the new year they are very helpful 
in making the Cool house attractive. They are of very easy culture pro- 
vided they are grown in avery buoyant house. Ours are given a position 
among the Cymbidiums. After the flowering season is over they generally 
lose many of their leaves, but this is no detriment, for it allows the young 
growths more light and air. When they are dying off do not give them 
quite so much water, but they should not be allowed to become really dry- 
As soon as the young growths are well started they should be potted, and 
the best results are attained when each growth is potted separately. A 
compost of two parts good loam to one part leaf soil will be found very 
suitable, adding plenty of sand and small crocks to keep it porous. Use 
ordinary pots and afford a fair drainage. After potting, water carefully till 
they are well away, and then they will be benefitted by copious supplies. 
‘A GooD INSECTICIDE.—I have many times been asked to name a really 
good and safe insecticide for the cleansing of Orchids, and one has been 
lately brought to my notice of which I cannot speak too highly. I have 
used it on the various sections of the Orchid family, and other plants, with 
great success. It removes filth very rapidly, and is very deadly on scale» 
thrip, &c., yet causing no injury to the foliage, and the plants present a
