SYSTEMATIC ALTERATIONS OF
CROPS.

:, tho cultivation of he ground, either in
farming or gardening, proper attention to the
,syolsr rotation OF crops forms one OF the hrst
and pripcipal features OF good managemen',al
,hooch its bea fetal influence has not yet been
fol,v accounted for by chemists. The rationale
II rotation is tirus given by Sir Humphrey
Davy ;-'!l Is a geeat advantage In the con-
verrble systems of cultivation, that the whole
nj the manure be employed and that those
nars of il. which are not fitted for one cror,
r4msio as nourishnent for another. Thus, ii
