and referred to my effay for the mode of carrying 
commutations into effeét:—But he has materially dif- 
fered from me in alfo adopting barley, oats, and but- 
ter, as: ftandards for varying the rent; and in pro- 
pofing that fuch variation fhould take place every 
year, and be governed by the average price of thofe 
feveral articles the preceding year. Mr. Davis is 
’ of opinion, that hops, hemp, flax, &c. fhould pay a 
certain price per acre, to be fixed by the legiflature; 
Jiable, neverthelefs, to rife and fall with the price of 
corn. As itis prefumed the Society would not have 
adjudged their prize-to this laft eflay, had they not 
confidered the deviations from my plan as material 
improvements, I truft that I fhall be favoured with 
an opportunity of {tating in'your next volume, my 
reafons for being of a different opinion. It feems to 
be .a duty incumbent on me to do fo, being firmly 
perfuaded, that fhould the author’s plan be carried 
‘into effect, it might operate very differently from 
what was intended, and be produétive of mueb 
injuttice. /
