I have had so much success in growing various tender plants in 

 greenhouses where the minimum winter temperature was never 

 lower, but very frequently as low as 35 Fahr. that it seems more 

 than likely that under other suitable conditions some of the hardier 

 of the Cool-House Orchids would do well. The experiment would 

 be an extremely interesting and valuable one.
