264 THE ORCHID REVIEW. [SEPTEMBER, 1915. 
4)dontoglossum, especially the O. crispum and Pescatorei types, also the 
numerous beautiful hybrids obtained from these and other Cool house 
‘species. Where a large collection of these Orchids are grown there are 
always some of them in bloom. Those which flowered early in the year 
are now making new growth, and the roots from these growths will soon be 
pushing freely in all directions, so that no time should be lost in affording 
fresh material to those requiring it. Although individual plants may be 
repotted at almost any time of the year, the month of September is the 
best time for a general overhauling of the oo and for giving to those 
that require it fresh pots, materials, &c. 
At this season the air is of so genial a nature that with very little trouble 
a suitable atmosphere for the plants can be maintained, and this, as every 
cultivator knows, is of the greatest assistance to the plants in quickly 
re-establishing themselves. The young breaks now pushing will soon 
send out roots from their. base, which, having new and fresh compost 
to root in, are well at home before winter commences. Those plants 
that are in a dormant condition should not be disturbed by repotting 
until their new growths are several inches high. A suitable compost for 
these Cool house plants is one consisting of osmunda fibre, Ar fibre, cut up 
moderately fine, and chopped. sphagnum moss in equal proportions, these 
being well mixed together, and a few small crocks added in the process of 
repotting, to keep the soil. porous.. Some growers prefer the addition of 
polypodium fibre, others osmunda fibre only, and, in many cases, with very 
good results. In all cases the pots should be clean, and about half-filled 
with crocks. Pot each plant with moderate firmness, keeping the base of 
the young growths about on a level with the rim of the pot. 
Some old plants may be in bad health through overflowering, &c., and 
any such should be turned out of their pots, and, when thoroughly cleansed, 
placed in pots as small as it is possible to get them into. Healthy 
specimens that need increased root.room should be merely turned out of 
the old receptacles and placed into larger pots without otherwise disturbing 
the roots. There will probably. be several back pseudobulbs on nearly all 
the plants. These may be severed at the rhizome, leaving two or three 
bulbs behind each leading growth. The back bulbs may be placed in small 
pots filled with crocks, and when they break may be potted. 
After repotting afford water sparingly, keeping the surface of the 
compost fairly moist, then, as time goes on, and the plants are making 
suitable progress, the amount of water may be increased gradually, always 
allowing the compost to become moderately dry before it is again watered. 
Keep the atmosphere fairly moist. Admit plenty of fresh air, especially at 
night, whenever the weather is mild, and always shade the plants from all 
strong sunshine.
