280 THE ORCHID REVIEW. 
that no plant suffers from drought. Cool Orchids enjoy the autumn night 
air, which should by no means be excluded. Any plants of Odontoglossum 
crispum which require repotting should be done this month, and not later, 
and those which it is unnecessary to repot may be re-surfaced with fresh 
sphagnum moss and peat. Slugs are usually a nuisance at this period, by 
eating the tender roots and spikes, and should be sought for at night. I 
think sea-shell gravel on the stages beneath the plants deters slugs, 
probably because it is sharp, which hinders them from travelling, or it may 
be that it retains a salty flavour. In any case our Cool house has been 
remarkably free from slugs since its introduction. 
In earlier Calendars, during that extremely dry weather, I recommended 
slight syringing overhead in the Cattleya and Mexican houses. This 
practice had better now be discontinued, or cases of damping may result. 
I am sorry to find a larger proportion of those Cattleyas and Lzlias that 
were the earliest to form their pseudobulbs starting to grow the second 
time. Ifasked to explain the cause, I could only suggest that the new 
growth having already become to a great extent matured and ripened 
during that long spell of excessively hot and dry weather, it is no more 
than we might expect, seeing the change of weather, which suddenly 
enveloped us in a humid, jungle-like climate. This, in my opinion, is why 
second growth has started, in spite of all the usual precautions. 
There are less Orchids in flower during the end of August and the 
beginning of September than at any other time of the year. Those that are 
now flowering are therfore most welcome. The foremost among them is 
doubtless the beautiful Cattleya Dowiana aurea. Take care of it, and give 
it a warm, light, and dry position for the winter, for it has a delicate 
constitution. Lelio-cattleya x elegans and its varieties do best in baskets 
at the warmest end of the Cattleya house. The usual time of flowering is 
the present season, but they frequently bloom at other periods, so that re- 
basketting may take place at almost any time during the summer or early 
autumn, when the plants present the right conditions; or it may be done 
immediately after flowering, supposing that it is not later than September. 
Good fibrous peat and fresh sphagnum moss is the best material in which 
to grow them. Leelio-cattleya xX amanda is another now in bloom, and 
requires similar treatment to the foregoing. Lelia crispa is another, and 
may be repotted when the flowers have faded. Cattleya Leopoldi and C. 
granulosa are also serviceable at this date, and may be repotted now or 
when they commence to grow the following spring. They require nothing 
more than the temperature of the Cattleya house, as do also C. Loddigesil, 
C. Harrisoniana, C. bicolor, C. velutina, and others. Cattleya Eldorado 
and C. Lueddemanniana are two other lovely species now in flower. The 
best way to grow them is in baskets suspended in the warmest house, and 
they also require a warm temperature when resting. Then there are Vanda
