fifty grains weighed an ounce. The produce of* 

 No. IL was three hundred and thirty-three ears, 

 lib. 2 oz. 8 dwts. of corn; fix hundred and eighty 

 grains weighed an ounce. The value of the crop 

 per acre of No. I. at 6olb. per bufhel, and five 

 fliillings per bufhel, is 26I. 9s. 4d. 



Now the great and important queftion is, what 

 is the principal caufe of fo great a produce? There 

 was no great expence,* and I am certain it was not 

 the goodnefs of the land; the lightnefs of the grain 

 feems to prove that: it has had no dung worth 

 mentioning thefe twelve years. The fnails having 

 eaten the plants in winter, I put a little foot and 

 lime on them, but that could not be the caufe. 

 There is much better wheat land not far from my 

 houfe, and in the hands of a good farmer; and 

 yet his crops are no more than about twenty-four 

 bufliels per acre.f It appears plainly, that there 

 muft be fome particular caufe, or caufes, of this 

 great produce; and likewifea caufe, or caufes, why 

 good land produces fo much lefs in common. 



* This could not pofllbly be afcertained by fo fmall an experiment. 

 If Mr. R . would plant an acre in this manner, and keep an accurate 

 account of the expence, I'ome opinion might be formed how far it 

 trould be either prafticable or profitable to attempt this mode of 

 culture on a large fcale. But nothing perfeftly (atisfaftory, or in 

 any refpeft declfive, with regard to general practice, can be proved 

 from very fmall experiments. 



^ ■{■ Three qu.arters of wheat per acre only, on good land, proves 

 "there muft be Ibme capital mifmanagement in the mode of cultiva- 

 tion; as in the Eaftern counties four, and very frequently five quar- 

 ters are railed per acre on clover leys of one earth.
