igo EXPERIMENTS ON WHEAT. Panlt 



in the common way. It was reaped at a proper time, and yielded 

 about 6646 pounds ; from which mufl be dedufted, firft the 850 

 pounds of feed, and fecondly, the value of the dung, which is eqiral 

 at ieaft to 1260 pounds of wheat j together 2 1 1 o pounds : which^ 

 deducted from 6646 pounds, the total produce, leaves the neat 

 produce 4536 pounds. "•v ~ 



" The crop of 1753 was dimlniflied by the hail on the third of 

 June. The value of this lofs is not known : but we may fairly 

 compare it with the experiment, No. 2. which likewife fuffered by 

 the fame hail. We confefs that this comparifon is not abfolutely ex- 

 adl, with refpeft to this accident : but it muft alfo be granted that 

 this circumftance cannot occafion any very great error. We muft 

 likewife premife, that we fliall not reckon the produce of a fmall 

 fpot which is pretty com.monly fowed in March in the- year offal- 

 low, becaufe it hardly equals the expence of dung and plowing. 



"The neat produce of the experiment No. 11, on a field fowed' 

 in equally diftant rows, was 2857 pounds 8 ounces. But the extent 

 of that field being but 2172 toifes, we muft calculate what the crop 

 would have been in proportion, if that extent had been 6087 toifes, 

 fappofmg it of the fame quahty. We fhall find that the field on 

 which our experiment was made, would have produced neat 8006' 

 pounds of wheat: deducting from which, 4536 pounds, for the 

 neat produce of the field cultivated in the old way, the difi^erence 

 in favour of the new culture, v/ithout dung*, will be 3470 pounds 

 of \^'heat. 



" We have feen by the experiment No. 2, that this field laid out in 

 beds, and having borne its fecond crop, yielded neat 1540 pounds 

 ef wheat. Its extent is but 1650 toifes; fo that we are to fee what 

 crop it would have yielded if its extent had been 6087 toifes, fup^ 

 pofing the quality of the foil to be the fame. The rule of three 

 fliews us again, that its neat produce would have been 5681 pounds 

 of wheat, which we are to double for the amount of the next year's 

 crop; every year yielding a crop in the new hufbandry : whereas the 

 field it is compared with, Vv'ould lie fallow this year. Thus two years 

 will yield 11 362 pounds of wheat; from which dedudling 4536 

 pounds for the neat produce of the fame field cultivated in the old 

 way during the fame fpace of time, the difference will be 6 82 6 

 pounds of wheat, in favour of the new hufbandry."
