This is a case where the difterent parts of the land, and 

 the capital employed on it, are nearly of uniform value ; and 

 where nevertheless the cultivation is bounded by the smallness 

 of the demand ; a state of things which would probably not be 

 permanent. 



29. If the average rent of the country be a given portion of 

 the produce, we can determine m. Let the average capital on 

 an acre be I times the capital on an acre of the lowest soil. Hence 

 c = lc„, and r — inr„. Now pr„ = qc„, and plmr„ = qmlc,,, whence 



plr = qmc. And the whole rent — arp — acq = arp M Y the 



produce being arp. Hence the produce is of the rent a multiple

 same quantity of very poor land, we shall have the corresponding
