According to this the treeless Plains, as far as the soil is con- 

 cerned chemically, except in the quantity of lime, if these analy- 

 ses are correct, have a first-class pine soil. The soil of the Jersey 

 Plains contains the following ingredients : 



Sample I. Sample II.

According to these analyses, even the Plains of South Jersey, 

 if ploughed and worked, then planted with a leguminous crop, 

 then ploughed again and limed and then planted with pines, 

 would probably produce a good crop, provided the soil is not 

 too dry. Very often a leguminous crop, such as cow-peas, may 

 not take the first trial owing to the absence of bacteroids in the 

 soil so that several attempts may be necessary. This probably 

 would not pay, but it would be an interesting experiment. It
