a tillage crop, upon either of these grounds, in their

by hurdles, upon the ground ; but not as a croj) to be 
pulled and removed ; because they are one of the 
most exhausting crops ; they will impoverish your 
soil, and thus defeat, in some measure, your object. 
Clover, and buck- wheat may be used upon both, if 
ploughed in when green, as a fertilizing crop, when 
the soils begin to mix, and become fertile ; both these 
soils may thus be reduced to a rich, profitable tillage, 
for every description of (jrop. The farmer must al- 
ways observe this cautign, that if he exhausts their 
strength by bad tillage, they will both revert to their 
original state, and become clay and sand again ; but 
-by good tillage, they will continue to improve, until 
the one becomes a rich clay loam, and the other a 
rich sand loam, fit for clover and wheat for ever. It 
is worthy of notice, that the substratum of sandy soils, 
(even dead blowing sands,) is most generally a strong 
clay ; thus nature furnishes the means of perfecting 
her works for the use of man, upon the same grounds ; 
the upper surface of sand may be removed, upon one 
side or corner of your field, and the substratum of clay 
be dug and carted on, sufficient for all the purposes 
required, and at very little expense. 
1 arn fully sensible that the high price of labour in 
our country, is a very serious objection to any very 
extensive improvements in reclaiming lands in this 
mode ; but such lands as are near to our dwellings, 
become more immediately the objects of our'atten- 
tion ; try these first, and you can then determine how 
far it will be for your interest to continue the improve- 
ments.
