HE general growing conditions in each division must be maintained, 
as advised in previous Calendars. To achieve this object consider- 
able pains must be bestowed upon the ventilation and shading of the 
houses, and the watering of the plants. In dull, sunless seasons, like the 
present, the atmospheric condition of the houses require special care, as the 
plants cannot thrive under unsuitable treatment. Success depends entirely 
upon the attention to detail, as regards temperatures, airing, resting, potting, 
watering, cleanliness, and the various matters which make up our practice. 
In spite, however, of the adverse weather conditions which we have 
experienced in the East Riding of Yorkshire, the plants with us have so far 
made quite satisfactory growth, and with the great amount of humidity in 
the atmosphere, we have been able to give more air to our plants than 
usual at this season of the year. The writer is a great advocate of fresh 
air being admitted to the houses at all possible times, but it should be given 
with caution during spells of hot, dry weather, as it is an easy matter to 
allow all the internal moisture to escape, especially if the top ventilators are 
used to any great extent. 
During the present month we often enjoy bright sunshine, and should 
we be favoured this season the most should be made of it, to ripen and 
consolidate the new pseudobulbs, this being no less important than the 
production of satisfactory growth. An ill-ripened plant never produces 
satisfactory flowers, and is rarely cultivated over a series of years. 
CaTTrLeyas, Leliocattleyas, and allied subjects should have attention 
as regards repotting, as previously advised. Plants of C. Warscewiczii 
(gigas), as they pass out of bloom, should be placed where they may receive 
more light and air, and at the same time the supply of water to the roots 
must be considerably reduced. In a short time new roots will be observed 
to be pushing from the base of the pseudobulbs, when any necessary 
repotting should be done. - Water should be applied to the newly-potted 
plants with the greatest caution until the roots have freely entered the new 
material. Sufficient water only to prevent the bulbs from shrivelling 
should be applied during the winter months, and early in February the 
plants will commence to grow. A light, dry position close to the glass 
should be found for them during the winter months. 
Cattleyas which produce their flowers during the autumn and winter 
months are now growing freely, and should have every inducement given 
them to develop. Light and fresh air are two of the greatest factors in 
helping these plants to develop: their flowers in a satisfactory manner.
