clearly prove, that where 4 Zs necessary to allow abouf as much corn t0 0xen as horses, the annual expence in the SUP- port of the former, wilt be much greater than that incurred in maintaining the latter animals: zhe ozen having each con- Sumed more hay weekiy, by near Six 8tones,?han each horse. 1 must also request their attention to that part of your corre- Spondent's letter in your 50th number, where he uscs the words,“ Singular privarion;* after which[ think thev will conclude, that I run no risk of being contradicted by him when I assert, that his five oxen against four good horsez, would require a very liberal allowance of corn. Towards the concluszion of my paper which contains the Comparative Statement, I Said,“It is easily deducible from the above estimates, that 106 maintain a working ox requires the Produce of about four, and to Support a working horse, that of about five acres of land." But it will clearly appear to those who will take the trouble of reading those estimates attentively, that when I used the words he has quoted, 1 ca/culated on 5x voven agamst two horses, and on the former receiving no(071. Notwitbstanding this however, A. M. Says(at page 319 of of your last Magazine)“1 am vot dispozed to follow A. N. with contradictory statements, I will take the estimate as he gives it;" and after quoting the above words, proceeds thus, “ If therefore it can be Snewn, that five oxen will perform the work of four horses, Your coriespondent will at least agree with me, that no additional expence 18 incurred? But when we allow each of his five oxen only as much corn as I have calculated upon for each horse, it is clear to demonstration, that while four of the latter can be properly Supported on the Produce of twenty, five of the former animals, would require very Iittle, if any thing, less than that of tuürty acres of land. With what justice then could he quote my authority for Stating, that five oxen, requiring a liberal allowance of c071, would not consume a greater quantity of the produce of the ground than four horses 7% However mnch I may be inferior to A. M. in mathematics and logie, I flatter myself that, after having proved that a working ov properly Sup- ported with corn, along with his other Food, annually cou- Sumes the produce of a much greater quantity of land than a workaung horse, your readers w1l1 not believe that I would diaw S0 absurd a conclusion, as that he has taken the liberty of placing to my account. In the last-mentioned page be also Says,“ It is professed, that two oxen driven by the plough- MAN, can perform nearly as much work as two g00d horses, and for a considerable lengtft of time.
