42 INTENSIVE FARMING 



industry. But it is within comparatively re- 

 cent years that the frame covered with a sash 

 or with muslin has come to be an important 

 factor in crop production at various points along 

 the Atlantic seaboard south of Baltimore. The 

 favorable soil and climatic conditions which ex- 

 ist there permit the development of this in- 

 dustry at all points favored with suitable 

 transportation. 



The frame industry is a notable example of 

 a high class of crop insurance, an insurance 

 which makes man master of all the factors of 

 plant growth save light and extreme cold. By 

 the use of frames the danger of injury from 

 frost, wind, storm, or drouth are eliminated. 

 Frame crops suffer only from severe cold (not 

 usual in the region) or lack of sunshine. This, 

 therefore, places it among the highly intensive 

 systems of farming. Intensive farming returns 

 large yields from restricted areas. Frame cul- 

 ture produces large yields from limited areas, 

 and therefore conforms to the definition of in- 

 tensive cultivation. It is also intensive because 

 some of the uncertain factors of ordinary 

 methods of crop production have been elimi- 

 nated. The more nearly crop production can 

 be made to approach the art of manufacturing 

 the more intensive (certain) it becomes.
