SMALL GREENHOUSES 207 



It keeps the frost from accumulating on either pane, 

 therefore the plants are not likely to be nipped if left 

 touching the glass on the inside, and there is no frost 

 to shut out the sunshine. Much of the sash in the 

 end is hung on hinges so that it can be swung outward 

 in summer, thus letting in plent}' of fresh air from 

 the end as well as roof.

I have what I consider a model greenhouse (Fig 

 53). In no other way could I have expended the 

 money and derived so much pleasure from it.
