A loamy soil, [which is a medium between these

may the sooner become dry.

SECTION VIII. 
Of a Rotation of Crops, aud the principles

we take, whatever expenses we incur, in collecting 
instruments of husbandry, in accumulating and ap- 
plying manures, and in tilling the earth; allis to 
little purpose, unless to these we superadd a succes- 
sion of crops, adapted to the nature of the soil—to 
the laws of the climate, and to the physical character 
and commercial value of the article raised. Peas 
will vegetate on wet cotton and wheat in pure 
sand; Indian cern will grow in high northern Iati- 
tudes, and the apple may be found near the equa- 
tor. We have seen sanfoin, struggling in wet clay, 
and aquatic plants on the top of an arid mountain; 
but all indicated the violence done to nature, and 
presented only specimens diminutive in bulk and

the value of produce, is as little to be denied, as
