the temperature they are subject to during their 

 growth should never be allowed to exceed 65°, 

 nor fall below 56°. They should also be placed 

 where plenty of air is circulated ; but during

 to 45° ; very little water should be given them 

 during this time, and the lower the temperature 

 the stronger will be their growth, and conse- 

 quently they will flower so much the finer.
