to dung fparingly or plentifully ; always paying a due

at which he can provide manure. 
Obfervation 3d. From the produce of No. 3, it 
appears, that undunged potatoes are preferable to a 
fummer-fallow without dung. And from comparing 
No. 1 with No. 2, it is clear that a dunged fummer- 
fallow is not fo profitable as a dunged crop of tur- 
nips, both followed by a crop of potatoes with dung.
