WINTER WORK IN GLASS HOUSES 



enough for one man in rose-growing, and he 

 should have a boy to assist him in busy times." 



So much, then, for running a good-sized 

 house. The next question of interest to the 

 beginner is the cost of construction, and this, 

 in a large measure, will depend on the owner's 

 pocketbook. 



There are three general types of glass houses 

 in use for the forcing of vegetables, strawber- 

 ries, and flowers, and these are the even- 

 span roof, the lean-to or shed roof, and the un- 

 even or broken-span roof. The wider the 

 house up to a certain point the easier it is to 

 heat, but wide houses require extra strength 

 in the rafters and uprights on account of the 

 greater weight. Some growers have been very 

 successful with single-span houses thirty feet 

 wide. 



For a beginner who does not wish to invest 

 a large amount of money, a house twenty feet 

 wide with an even-span roof will prove the most 

 economical to build. But should he be willing 

 to invest more at the start a shed-roof structure, 

 30 by 100 feet, will be found very satisfactory.
