In a former paper we have fhewn, that an acre of 

 land, properly cultivated with potatoes, will produce 

 337 bulhels, and the total expence of cultivating an 

 acre, rent and tithe included, was 61. 13s. yfd. If 

 three cows eat feven bufhels per week, then they 

 would eat 365 bufhels in a year; and twenty cows 

 would confume 2433 bufhels. The queftion then 

 is. If 20 cows require 2433 bufhels to keep them a 

 year, and as above an acre of land properly culti- 

 vated will produce 337 bufhels nett, how many 

 acres will be required to produce 2433 bufhels, or 

 the quantity necefTary to feed 20 cows to keep them 

 in full milk the year round ? The anfwer is. Seven 

 acres and a quarter nearly. 



If then an acre of land can be cultivated with 

 potatoes, as above, for 61, 13s. 7^d. the cultivation 

 of feven acres and a quarter will amount to 48I, 8s. 

 $id. We have feen, as above, that the rent of a 

 dairy farm, capable of maintaining 20 milch-cows, 

 is upon a medium 60I. but it clearly appears that 

 the fame number of cows may be kept equally well 

 on a very fmall part of an arable farm planted with 

 potatoes for ill. i is. 2id. lefs than that fum, which 

 is fo much in favour of the arable farm^ or in other 

 words, feven or eight acres of arable land, under this 

 mode of management, are as much fuperior to forty- 

 eight acres of meadow or paiturc, as the difference
