nts which are not clean should be cleansed, their pots where it is
required washed, and the staging and any part of the house requiring it
thoroughly cleansed before the plants are rearranged. During the course
of the work certain plants which would be benefited by being repotted,
or divided, will be found, and these should be given attention. The
water in the tub in which the green deposit on the pots has been removed
by scrubbing, and as much of the other water used in cleansing as can be
dealt with, should be poured down a drain outside the Orchid house. If
thrown on the floor of the house, it leaves an unpleasant odour, which
is harmful and lasts a long time.

During the inspection at the end of the summer the staging should be
repaired where necessary, the heating apparatus carefully overhauled and
defects made good, in order to minimise the risk of having to do the
work during the cold weather. Where it is deemed advisable to black the
hot-water piping, use only lamp-black and oil. Paint gives off injurious
gases for a considerable time, and where persons have been incautious
enough to use gas-tar the most lamentable results have followed, the
mischief lasting for years. These periodical inspections and
rearrangement of the plants are also useful in preventing the same
plants occupying the same positions for too long a time. A change of
position in the house is beneficial, even where the plants are not
crowded; but in collections where the plants are closely arranged, to
change their positions frequently, goes far to mitigate the evil
arising from want of space. In preparing for a thorough inspection of
the plants in a house, it is desirable to remove a number of the plants
to another house to make room to examine the rest without risk of
breakage, the plants removed at the commencement being returned to fill
the space remaining after the work has been completed.

The Orchid grower is always supposed to have the plants under his direct
inspection and to treat them with individual care, but these occasional
reviews often reveal defects in some of the specimens which would
otherwise have escaped for some considerable time.

ORCHIDS FOR THE CONSERVATORY

There are many dwelling-houses of moderate pretensions, especially in
towns and suburban districts, in which the sole accommodation for
plant-growing consists of the conservatory adjoining the house, and this
is, in most cases, heated by one
