Callahan GREEN ROUSES 
F ALL and winter, the destroyers of outdoor life are just around 
the comer. But you can enjoy the fragrance of flowers in your 
home, have fresh things for your table and revel in the beauty of 
your garden all winter if you erect a Callahan Sectional Greenhouse 
NOW. There are beautiful houses for both suburban homes and 
city residences. 
Callahan greenhouses are es- 
pecially practical for those who 
garden in theirspare time whether 
for pleasure or profit. The scientific de- 
sign and careful construction insure suc- 
cessful gardens. The side walls are 
insulated with the "dead air” cell method. 
All wood parts are Red Cypress and the 
roof supports are pipe purlins. 
Built in completely finished unit 
sections, Callahan greenhouses 
eliminate erection costs. Anyone 
can quickly and easily bolt the sections 
together — even the hardware is attached. 
In the new Greenhouse Book you will 
find illustrated a style which will fit into 
your grounds with every appearance of 
individuality. Write for your copy today.
