How to make a cold frame. The size of a cold-trame 
sash is three by six feet. The length of the cold 
frame will depend upon the number of sashes to be 
used. Make a frame that is six feet wide, eight inches 
high at the front, and twelve inches high at the back. 
Either one-inch or two-inch lumber should be used. 
Fie. 111. A Lean-to Cold Frame 
A lean-to cold frame. A lean-to cold frame may be 
made by nailing a two-inch by four-inch piece of lumber 
against the south side of a building and then con- 
structing a frame as indicated in Fig. 111. It is better 
adapted to early spring and late fall use than the more 
exposed frame. Keep manure or straw packed around 
it durmg cold weather. The frame may be covered 
with mats and boards during the winter and used as 
a place for storimg cabbage, carrots, turnips, and other 
root crops.
