The Short Span to the South. 27 



me to the conclusion that were I to build a house for 

 myself as an experiment, it would be as shown by an 

 end view in Fig. 17. Nothing should join it on either 

 side, and if for carnations, it should have wall ventila- 

 tion on each side, and continuous on both the north 

 and south roof, the south ventilator being hinged at 

 the bottom, the north at the top. For roses, the same 

 in every respect save that both continuous ventilators 

 would be hinged at the ridge. 



Mr. Dorner feels that he obtains more light during 

 the short days under the new system than with the 

 old, and about the only criticism I could find when 

 there, aside from the frost on the long roof, was that the 

 south gutter cast a shade during the latter part of the 

 day on benches built low enough to be handy.. This 

 could be obviated by lowering the south gutter as far 

 as it can be and leave room for a foot of ventilation be- 

 tween it and the grovmd. 



With all the facts it has been possible to obtain up 

 to the present time, for my own use I would not feel 

 justified in changing the old style for the new until the 

 latter has been more thoroughly tested. 



Still another plan is advocated by some, which does 

 awav with the objection found in the system last men- 

 tioned, so far as snow and frost are concerned. I know 

 of but one grower who has adopted this style of build- 

 ing, but there may be others. This gentleman thinks 

 he finds in it the advantages claimed for the former
