ORCHIDS AND THEIR 
CULTIVATION 
Following the keen interest evinced in our 
personal instruction classes on Orchid Culture and 
to fulfill the demand advanced by numerous in¬ 
terested persons unable to attend because of 
distance, we are instituting a correspondence course 
in this subject. The entire series of ten lessons will 
be conducted by Cyril Warren, who has had forty 
years experience in the collection, growing and 
merchandising of orchid plants and their flowers. 
The subjects will be: 
1. Securing Orchid plants. Practical and initial 
care. 
2. Watering and humidity control. 
3. Shading various types of Orchid plants. 
4. Potting instructions for different species. 
5. Vegetative propagation - increasing plants 
by cuttings. 
6. Insect pests and their eradication. 
7. Treatment of different types of Orchids dur¬ 
ing flowering. 
8 Hybridization of Orchid flowers for seed. 
9. Construction of buildings for Orchid culture. 
10. Heating of structures. 
The first lesson will be mailed immediately 
upon receipt of enrollment fee and each lesson 
thereafter will be mailed to the student at two 
week intervals, subject to him having answered the 
five questions which are at the end of each lesson, 
in a manner satisfactory to the instructor. In ad¬ 
dition, each student will be entitled to ask the in¬ 
structor five questions concerning his own Orchid 
problems. 
This course will enable both the amateur with 
no experience and the man with some knowledge 
of orchids to fulfill his desire to grow these floral 
aristocrats around which has been drawn a veil 
of mystery. ..
