NEW HUSBANDRY EXEMPLIFIED. 229 



** three pounds; which muft be allowed to be 

 " a mere trifle, efpecially if it be confidered

[It has been obferved above, that a pair 

 of wheels are convenient, to mark the in- 

 tended diftance of the rows, or ridges, very 

 ftraight; a mort ftone roller likewife, plain 

 or fluted, though not abfolutely neceflary, 

 is fometimes very ufeful, to break and crufh 

 the large clods in the intervals in very dry 

 weather, efpecially in ftrong land. Such 

 a roller in a pair of (hafts, and mort enough 

 to be drawn along the intervals, will effec- 

 tually crum thefe hard clods, without wait- 

 ing for rain, or hindering the hoeing. One 

 horfe is enough for this roller : and, if the 

 earth in the interval lies in a (harp ridge, it 

 will be convenient to open that ridge firft, 

 that the horfe may walk, and draw the 

 roller after him, in the interval. This is 

 fometimes of great fervice, as it prefently 

 and effectually pulverizes the earth in the 

 intervals ; but mould be ufed only when 

 the earth is very dry.] 



" Prejudice and intereft, fays the author, 

 <{ frequently warp the judgement, and make 

 " men violent in the defence of one fcheme, 

 '* to the utter clcftruftion of another; though 

 '* perhaps equally ufeful and delirable, under 

 " different circumflances. The truth of this 

 " obfcrvation appears no where in a ftronger
