A FEW HINTS ON THE MANAGEMENT OF TERRESTRIAL ORCHIDEiE. 151 
The height of the back wall of the house is 11 feet 6 inches, and that of the 
front 2 feet 6 inches ; on the top 
of the front wall is an elevation of 
glass 2 feet 6 inches high, making 
the front 5 feet high. 
In front of the house is a small 
pit, used for half hardy plants, i. 
The water is conveyed into the 
cisterns by leaden pipes from a re- 
servoir, and is let on or taken off 
at pleasure by turning of taps fixed 
at each end. To readily give hu- 
midity to the house, pipes are passed along the house, perforated as at ^ ; and when 
turned on, throw water on the floor, or over the back chamber.
