yield of 239 bushels from an acre of land in South Carolina. On our
little farm in Illinois we have one field of sixteen acres, which
was used for a pasture and feed lot for many years by my grandfather
and has been thoroughly tile-drained since I was born, that has
produced as high as 2,015 bushels of corn in one season, thus making
an average of 126 bushels per acre.

"What I try to remember is the plant food requirements for such
crops as we ought to try to raise, if we do what ought to be done. I
try to remember the plant food required for a hundred-bushel crop of
corn, a hundred-bushel crop of oats, a fifty-bushel crop of wheat,
and four tons of clover hay. It is an easy matter to divide these
amounts by two, as I have really been doing here in the East where
it is hard for people to think in terms of such crops as these lands
ought to be made to produce.

"The requirements of the clover crop I certainly want to have in
mind as a part of my little stock of ever-ready knowledge. It is not
very hard to remember that a four-ton crop of clover hay, which we
ought to harvest from one acre in two cuttings, contains:

160 pounds of nitrogen,
31 pounds of magnesium,
20 pounds of phosphorus,
120 pounds of potassium,
117 pounds of calcium.

"It is just as easy to think in these terms as in per cent. or
pounds of butter fat, which I understand is the basis on which you
sell your cream."
