 hut avoid giving it in excess, tempering it as much as possible by- 

 damping the house once or twice a day, as may be thought

 See that no Orchid overhangs or shades another, studying 

 which place in the house is most suitable for each plant, and 

 when such a place is found, keep it there until the end of the 

 winter or longer. Damping once or twice a day, as may be 

 found necessary.

 60" to 68" ; night, 63° to 60° : morning, 60° to 63°. 

 If any ventilation is needed it must be carefully given, avoid- 

 ing extremes in temperature, and on no account try to force 

 Orchids by a superabundance of heat and moisture. In exception- 

 ally severe weather it is best to keep a coveiing on the roofs, day 

 and night.
