370 THE ORCHID REVIEW, 
be prevented altogether. In the case of very rare and valuable plants it is 
best to secure an off-set at the first opportunity, so that in case of a mishap 
there is a spare string to the bow. Most Orchids propagate freely enough 
from the old pseudobulbs when the connecting rhizome is severed between 
the back bulbs and the leading ones, of course leaving a reasonable number 
to support the leading growth. 
Another amateur, who is evidently a recruit to the ranks, has several 
Cattleya Gaskelliana ‘‘ which have made their growths and formed their 
sheaths, but show no sign of pushing spikes. Should I rest them or keep 
them growing?” Generally speaking, a Cattleya having formed a sheath 
will in due time push its flower ; though sometimes it fails to do so; and 
occasionally they will push a spike without asheath. C. Trianz, C. Mendelii 
and C. Mossiz often flower without the sheath, and on that account, if the 
last new bulb is minus a sheath, care should be taken when cleaning not to 
touch the point from whence the spike would issue. But in the case of 
Cattleya Gaskelliana, with or without a sheath, if the flowers do not push 
directly the pseudobulbs are completed, there is no hope that they will do so 
afterwards, and the plants should be treated exactly like those which have 
flowered. 
Step by step the Orchidist finds for his plants places that are most 
favourable to growth, and having done this it is well to be cautious before 
removing them again, unless for the purpose of resting. Of course a suit- 
able temperature is the main thing, though a suitable position for a plant 
is far more important than is generally thought, and I would recommend 
new beginners to be particularly observant in this matter of positions, for 
it can soon be seen if a plant is ‘‘at home”’ or otherwise.
