  The analyses of the two samples of red soil are good dupli-
  · . I cates, as they should be from their situation in the Held. They
  show lower percentages of nitrogen andz easily soluble potash
  than would be expected from pasture land that has never been
  cultivated, which is in agreement with the presumption that this  
Z , land was a long time in cultivation before it was made a pasture.
i i The fact that the soil had been recently turned probably caused
more than the just proportion of the subsoil to be taken in the .
sample, thus lowering the apparent availability of the potash.  I
_ I The black soil is materially richer in the important elements than
1 I the red, probably the effect of washing. The high solubility of e
  the phosphates in this soil is noteworthy.
  I The next two samples are of the same type of soil as No.
