CHAPTER XXII 
FRAME CROPS 
Frames vs. greenhouses.—It is generally conceded that 
greenhouses, especially in northern sections, possess, for 
the forcing of most vegetables, distinct advantages over 
frames. This subject was discussed more fully on 
page 13. It would be folly, however, to take the stand 
that there is no place for the use of frames in the forcing 
of vegetables, for this is far from the truth. Even many 
of our most successful and extensive northern greenhouse 
vegetable growers have large areas of frames. They are 
adapted to the growing of certain crops, especially the 
cool ones, such as lettuce, radish, cauliflower and other 
hardier classes, as, for instance, the dandelion. They find 
a most useful place in the operations of gardeners living - 
near the seashore, particularly southward, where the ex- 
tremes of temperature are not so great as in farther in- 
land northern districts. In the warmer sections of the 
country, some crops, as head lettuce, thrive much better 
in frames than in superheated greenhouses. 
Gardeners with limited capital can engage in vegetable 
forcing by purchasing only a few sash. As the profits 
increase, additional sash may be obtained, so that in the 
course of a few years an important enterprise may be 
established. Frequently the sash are used in the con- 
struction of cheap greenhouses, and in these greenhouses 
the process of evolution is followed by large modern 
ranges. 
Importance of frame forcing—Very large areas in 
various parts of the country are devoted to frame crops. 
The most extensive plantings are in North Carolina, 
though frames are used on a large scale in all of the South
