effective must be very frequent fumigations—say three 
times a week, till they are exterminated. Heavy 
fumigations are not necessary, but they must be 
frequent, and in the long run the outlay in tobacco 
paper will be considered money well spent. Frost 
will destroy those insects on outdoor plants.”] 
ORCHIDS IN THE OPEN AIR. 
It will he remembered by our numerous readers 
who are interested in Orchids that Mr. Smee tried the 
experiment last year of placing a large number of 
Orchids in the open air, and permitted them to remain 
there for some two or three months. Encouraged by the 
results of the experiment, a much larger number of 
plants have been placed outside this year. These plants 
we inspected early in the present month, when many 
were still outside and some flowering, while those that 
had just been housed were in the finest possible condition, 
with thick dark green leathery leaves and strong bronzy 
looking pseudo-bulbs. Several were flowering, the most 
noticeable being Dendrobium Wardianura, the growths 
of which were covered with flowers as if in spring. 
The plants, except Dendrobiums, which were in the 
full sun, were arranged on planks just above the water¬ 
courses that intersect the garden, and which are quite 
canopied with the foliage of overhanging trees and 
shrubs. The position is thus peculiarly favourable, and 
similar advantages are present in few gardens; there¬ 
fore, successful as Mr. Smee’s experiments have un¬ 
doubtedly been, the whole circumstances should be 
remembered, as it is not to be expected that Orchids 
would do equally well in the open air in higher and 
drier situations. The photographic group, fig. 6(5, 
represents the Orchids in the garden in question. The 
scene, it will be admitted, is a tropical one; and the 
following careful record has been supplied by Mr. 
George Cummins, the able gardener at Hackbridge :— 
” These have done better during the past summer, 
doubtless on account of more sun and warmer weather 
than last year. The heavy dews at night during August 
and September evidently suited them well. Some 
moi'nings the leaves had the appearance of being 
syringed. During those months the plants required very 
little water or attention. About 1000 plants have been 
treated in this manner, not one having shown any dislike 
to the open air, while the majority have enjoyed it and 
made far more satisfactory growth than the same 
varieties have done in the houses. 
“ The Dendrobiums growing in pots were placed on a 
platform b feet wide over a ranning stream in the full 
sun on August 11th. Most of them had made an early 
growth, and when taken in one was in bloom and others 
showing well. This year many of this family will be 
ill bloom before Christmas, which have previously 
bloomed in spring.
