Surprise him by being prepared 
Remember how year after year he has “nipped” those late 
sowings of short season crops that you so fondly nursed 
along, hoping to gather them before frost did it? Don’t 
give frost a chance to foil your plans this year! Prepare 
for late summer and fall crops of vegetables by sowing 
seeds in hotbeds. Frosts don’t kill fond hopes and 
crops, and winter puts no end to gardening opera- 
tions, with the man who is equipped with 
Crisry, tender Lettuce 
Three weeks after 
sowing. 
Easily and quickly put up. Comes in sections already glazed, with heater and 
subframe. When ready for business it gives you 40 square feet of growing space. 
Intensively cultivated, this will yield an abundance of radishes, beets, greens 
— any vegetables suitable for growing under glass, plus some flowers for yourtable. 
Think of the joy it will be to gather your own crisp lettuce while snow covers the 
ground and the market supply at 20 cents per pound looks wilted and stale. 
The material and workmanship that go into the construction of all “Duo- 
Glazed” products makes them a safe investment. With reasonable care they 
offer life-time service and enjoyment. The crops raised will soon pay for the equipment. 
The operating expenses are the lowest possible, the returns for every effort the highest.

Callahan Duo-Glazed Sash Co. 
Duo-Glazed Sash converts a hotbed into a miniature greenhouse. The 
double layer of glass holds a “dead air” space, which is a most effective 
insulator against changes in temperature. By the use of Duo-Glazed 
Sash, hotbeds are easier to manage, coldframes become frost-proof and 
the cost of greenhouse operation is reduced to a minimum. In hot- 
beds guarded by it you can raise beets, lettuce, radishes, spinach, 
Swiss chard and many other vegetables, easily and economically all 
winter. Pansy plants, violets, narcissus, hyacinths, and many other 
flowers may be forced to bloom throughout the winter under Duo- 
Glazed Sash, regardless of outside temperature. 
Styles for Every Need — 
Sizes to Suit Every Pocketbook 
Whether you only want one sash or a thousand, a little “lean to” or a 
complete little greenhouse — we can fill every need, please every fancy. 
Moreover, we are sure of what Duo-Glazed Equipment

sands of practical gardeners have proved the ease with

hardship, to a certain success.
