AUGUST, 1912.] THE ORCHID REVIEW. 245 
ODONTOGLOssUMs.—Two little favourite Odontoglossums, namely, O. 
Rossii and O. Cervantesii, may have now any necessary attention as 
regards repotting. They prefer small pans, and should not be pulled to 
pieces more than is necessary to make them into shapely masses when 
repotting takes place. The whole of this family may be gone through as 
they get into the desired condition. The compost recommended for 
Miltonias, will answer their requirements. Odontoglossum hybrids have 
reached such numbers, and such complicated parentage, that it is obvious 
that many of them require some thought and judgment to satisfy their little 
peculiarities, which I cannot attempt to give in detail, so I advise every 
grower to carefully observe how his plants succeed under the different 
conditions they are placed in, by these means he will be able to satisfy the 
requirements of the most fastidious. 
GENERAL REMARKS.—The present month affords a suitable time for the 
overhauling of the heating apparatus, and putting the same in good working 
order for the winter. A careful examination shou!d be made of all joints, 
and any that leak must be made good. The valves and air taps should also 
be examined and put in thorough working order. Boilers that are old and 
worn should be replaced with new ones while the weather is favourable for 
such work, being then done without much risk of injury to the plants. 
Faulty boilers generally break down when the weather is severe, and then 
there is always a risk of considerable harm being done to the plants. 
The usual routine of cleaning, potting, &c., will comprise the principal 
work for the month. Towards the end of the month a general preparation 
must be made for putting the different plants into their winter quarters, and 
the glass should be thoroughly cleansed to admit as much light as possible 
‘during the dark days of winter. 
THE HOLLAND HOUSE SHOwW. 
HE Summer Show of the Royal Horticultural Society was held at Holland 
House, Kensington, on July 2nd, 3rd, and 4th, and brought together a very 
fine display. The number of visitors was also very large at the outset, when 
the weather was bright and fine, though later on the attendance was limited 
by incessant rain. The Orchids on this occasion were mostly staged in one 
of the side tents, and included several very fine groups. The awards 
consisted of two Gold and five other Medals, two Silver Cups, three First- 
class Certificates, four Awards of Merit, and one Certificate of Appreciation, 
while two other Medals were given partly for Orchids.
