CATTLEYA INTERMEDIA. 
3. Never suffer the plants to be exposed to dry parching winds, hut if possible 
give air through ventilators, so situated as not materially to affect the humidity of 
the house, or come in contact with the plants. 
4. Shade is essential to their welfare, therefore never permit them to be exposed 
to violent sunshine : if the sun be powerful, throw a woollen net over the glass. 
Any slight shade occasioned by creepers, or anything which will not darken the 
house too much answers the purpose. 
5. They require but little water at their roots, providing the atmosphere in which 
they grow is very humid. Carefully avoid sprinkling water on the leaves, as many 
species of orchidea have been found to receive great injury from the practice. It is 
always requisite that the water used should be of the same temperature as the 1 
house in which the plants grow. 
6. The best sort of soil for them is a sandy peat, containing as large a portion of 
fibres as possible, mix with this about one-third of broken potsherds, and be careful 
not to place the plant too deep in the pot. They will grow also on a piece of 
rotten wood, set or hung up in the stove. In this case they merely require a little 
moss tying round the bottom of the stem, to facilitate the growth of the roots, but 
this is not to be recommended for general practice. 
7. In potting always be careful to give a good drainage ; this may be done by 
filling about one third of the depth of the pot with broken potsherds. Although 
the plants are fond of moisture, they never thrive, except the water has a free 
passage through the pot.
