CHAPTER XIV 



Best Type of Greenhouse 



It is unanimously conceded that the greenhouse of 

 100 per cent, efficiency for Carnation growing is the house 

 to which the word " general utility " can be applied. 

 The detached even span house of iron frame construction, 

 or what is termed " reconstructed construction," having 

 concrete sides and cast iron sills, has been universally pro- 

 claimed to be the last word in " safety first " greenhouse 

 construction. 



Opinions differ radically among growers as to the 

 most economical width at which to build, but undoubtedly 

 the 37 ft. to 48 ft. house comes nearest the true economical 

 ideal. But houses up to 78 ft. wide are in favor. On the 

 ipest modern type iron frame greenhouse, all strains have 

 been carefully calculated, every part and every connec- 

 tion being made amply strong with the proper safety factor, 

 so that there is absolutely no chance for failure. Foot 

 pieces are made heavy and broad, and in such shape that 

 when embedded in concrete they are held so rigid that 

 there is absolutely no danger of disturbance by the reflex 

 action which occurs in heavy winds. 



In deciding in which direction the ridge shall run one 

 has to be guided by the individual available location, 

 but the ridge running east and west and 26 J/2 deg. pitch 

 roof, will give the best success. 



Wide houses are infinitely preferable to narrow ones 

 and have everything in their favor. Better to build a
