BUILDING THE RANGE 89 



forcing the liquid manure over the range. The size of 

 the tank and also that of the engine and pump varies with 

 the size of the range, and only an approximate estimate 

 of the cost of these can be given. 



To arrive at the approximate cost of constructing a 

 house, a definite proposition may be valuable. We 

 will, therefore, estimate the cost of constructing a medium- 

 sized range of carnation houses. As many growers now 

 prefer to have all their plants under one roof, rather than 

 have several houses, an up-to-date, large, iron-framed 

 house of truss construction will be the basis of this 

 estimate. Cheaper and smaller houses could, of course, 

 be built, but these figures may form a basis for com- 

 parisons. 



71. An estimated cost of construction, equipment, and 

 maintenance of a modern range of greenhouses. These 

 figures were obtained from a reliable commercial grower 

 who has recently built and equipped a new range. Es- 

 timates were also furnished by construction firms, with 

 little variation from these figures. 



Construction of range complete : 



Estimated cost of constructing foundations and super- 

 structure, with heating pipes, for a greenhouse 

 covering 24,000 square feet $13,000 



Boilers of sufficient capacity to accommodate one other 



house of equal size, and piping for same .... 3,000 



Service building with cellar, thirty feet by forty-four 

 feet, of concrete foundations, and concrete blocks 

 above grade 3,100 



Chimney (round), seventy-five feet high, of common, 



hard or radial brick, lined part way with fire brick 1,000 



Excavating for foundations, boiler room and other 



grading 1,500 



" Pecky " cypress for benches 2,000
