Forcing Houses or Pits. — 91 



house, plan (cross-section) of which is here given. I do not 

 think it necessary to go into all the details of construction, heat- 

 ing, etc. Any person intending to build a greenhouse of any 

 kin should not only study works on greenhouse construction, 

 but also visit the greenhouses in his vicinity, and talk with the 

 men who run them. Many good suggestions may be gathered 

 by such a course.
