Excerpt from An Ecological Study of Prairie and Forest Invertebrates In four generations a true wilderness has been transformed into the present prosperous State Of Illinois. This transformation has been SO complete that in many parts Of the state nearly all of the plant and animal life Of the original prairie and forest has been completely terminated. Between the degree Of change which has taken place in any given area and the suitability Of that area for agriculture there has been an almost direct relation. Fortunately, however, for the preser vation of prairie and forest animals, the state is not homogeneous, some areas being too hilly, rocky, or sandy for prosperous agriculture.
