146 EXPERIMENTS ON WHEAT, Part II. 



ftand five or fix days longer. It remained in the field fi^ur days, to 

 dry, and was thraflied towards the latter end of Auguft. It yield- 

 ed an hundred and forty two pounds of wheat, at eighteen ounces 

 to the pound. 



" Tliis wheat was very fine, perfedlly clean, and the grain much 

 larger than in common. 



" This experiment gives juft rife to the following remarks. 



" Firfl; the earth of thefe three beds having been pulverifed and 

 brought to a very loofe ftate by the horfe-hoeing in 1751, the plants 

 were ftronger and more thriving than thofe of the year before ; a 

 circumflance which contributed to the increafe of the crop. 



" Secondly; this crop juftifies my eftimate, that this fpot of ground 

 could yield 210 pounds of wheat in one feafon, if cultivated accor- 

 ding to the principles of the new hufbandry : for if we add to the 

 142 pounds reaped this year, the lofs occafioned by the birds and 

 fnails, it is pretty evident that the whole produce would have nearly- 

 amounted to 210 pounds. 



" Luckily, that I might be more thoroughly fatisfied what lofs I 

 fuffered by the birds, I counted in two different places how many 

 ftalks the plants in the three rows had yielded. On a length often feet,, 

 I found 1600 in one place, and 2030 in another. As I would al- 

 ways avoid over-ftraining my calculations, I fhall only fuppofe that 

 every ten feet in length produces 1600 {talks: the beds, being 160 

 feet long, will confequently contain at leaft 25600 ilalks, and the 

 tliree beds together 76800 ilalks, or ears. 



" To know in the next place how many pounds of wheat might 

 be contained in that number of ears, I had as many of them threfhed 

 a month after harveft, as yielded a pound of eighteen ounces. They 

 were taken- at random, without culling them, out of a fheaf whicb 

 feemed to have been but little damaged by the birds. 



" Three hundred and uxty ears yielded thofe eighteen ounces of 

 wheat: fo that, dividing 76800, the whole number of ears, by 

 360, the produce of the crop would be 213 pounds 6 ounces, at 

 eighteen ounces to the pound, or 240 pounds of fixteen ounces. 

 Hence it appears, that my firil eftimate was pretty juft, and that the 

 produce may be even more confiderable hereafter. 



" Thirdly; this fpot was clear of weeds; though it ufed to be over- 

 run with them. It appears by this, that the new huft)andry deftroys 

 them eftedtually; though this advantage will be lefs felt the llrft year 

 than in other fubfequent years.
