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:

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
