 Iron and steel framework is largely used by 

 the best builders and generally accepted 

 by their customers. While comparatively 

 few houses are used for chrysanthemums 

 the entire year, there are a great many 

 houses built for the express purpose of 

 growing them. Various forms are used with 

 equally good results, but one of the best is
