ON THE CONSTRUCTION OF A HOT-HOUSE. 



There have been many plans devised and visionary 

 projects offered to the public as the best for a well re- 

 gulated Hot-house. As we intend forming one for prac- 

 tical purposes, we shall adopt a convenient size, have 

 flues for the conveyance of heat, and coal or wood for 

 fuel. 



Site and Aspect. The house should stand on a situa- 

 tion naturally dry, and if possible sheltered from the 

 north west, and clear from all shade on the south, east 

 and west, so that the sun may at all times act effectu- 

 ally upon the house. The standard principle as to 

 aspect is to set the front directly to the south. Any 

 deviation from that point should incline to east. 



Dimensions. The length may be from ten feet up- 

 wards ; but if beyond thirty feet, the number of fires and 

 flues are multiplied. The medium width is from twelve 

 to sixteen feet. Our directions will apply to the two 

 extreme points, viz. thirty feet by sixteen, and in height 

 at back from twelve to eighteen feet ; the height in 

 front six feet, including about three feet in brick base- 

 ment to support the front glass, which will be two and 

 a half feet, allowing six inches for frame work. 



Furnace and Flues. It is of great importance to have 

 these erected in such a manner as will effectually heat 

 the house. The greatest difficulty is to have the fur- 

 nace to draw well. As workmen are not generally 

 conversant on the subject, nor yet understand the effect
