with a 31% inch pot of linseed oil. At the beginning of the summer, when 
even more shade is required, the amount of white lead in this formula is 
increased to 25 pounds. From that time on, we do not add any oil and 
gradually cut down on the weight of the white lead. This formula will bear 
the application of judgment since the amount of shade needed varies with 
location and climate. 
It is far better to apply the mixture to the exterior of the house in fre- 
quent, thin coats than to make heavy applications. In the final analysis, 
heavy applications may defeat the purpose of proper shading and are 
difficult to remove. 
The successful growth of Cattleyas depends to a large degree on the 
light which these plants receive. Light should be admitted to the point of 
turning the leaves a light yellow-green color. If one or two leaves are 
burned about the time shading is first applied or when shading is taken off 
or when heavier application is needed, you will know that you are giving 
the plants the maximum amount of light. 
These suggestions are offered on the basis of the successful methods 
developed over a period of years at Orchidhaven. The growth of Cattleyas 
requires only simple, basic rules. The magnificent blooms which these plants 
produce are a rewarding experience for every one who enjoys the thrill of 
seeing fine and beautiful flowers grow under watchful care. It is a creative 
work which repays the amateur in many happy hours.
