GREENHOUSE 



rafters, which are no longer used, cost much 

 more than these bars, interfere greatly with the 

 admission of sunshine, and add nothing to the 

 strength of the roof. If sash-bars ten 

 to twelve feet long are given the support of 

 one one-inch pipe, running lengthwise of the 

 house, no other support will be needed by the 

 roof. This pipe should, of course, rest on 

 upright piping set about eight feet apart, to 

 prevent it from sagging under the weight of 

 the glass of the roof. To-day the frame-work 

 of the best greenhouses is composed largely of 

 iron piping which fits together with screw joints. 

 This gives a rigid but light and airy-looking 

 frame, and one that offers but little resistance 

 to the entrance of light. The up-to-date car- 

 penter will be able to apply the suggestions 

 made to the house he builds in such a manner as 

 to make it effective and satisfactory without 

 the expenditure of much money. 



DECIDE the size of the house you want, 

 and then let him draw plans for it and 

 make an estimate of probable cost. First- 

 quality lumber will not be required for board- 

 ing if sheathing-paper is used liberally,
