Heart-of-Egypt is a small station on the double track of the
Chicago-New Orleans line of the Illinois Central, and there are
three other railroads passing through our County Seat. Poorland Farm
is less than two miles from Heart-of-Egypt and only five miles from
the County Seat, with level roads to both.

As to the soil, I may say that in some respects it is poorer than
yours, but in others not so poor. The amount of plant food contained
in six and two-thirds inches of the surface soil of an acre,

By referring to the invoice of your most common land, you will see

abundant element potassium. In the supply of nitrogen we have a
distinct advantage, because our soil contains nearly three times as
