TRACTS ON VARIOUS SUBJECTS, &c. 97 



The total produce, at this rate, from 1100 sheaves, would there- 

 fore be, 



Of clean corn, - - 4800 pounds 



Of straw, - - 4500 ditto 



It will be found upon calculation, that this produce per acre is 

 4189 pounds of corn,* and 3927 pounds of straw. 



This is no more than a return of 35 for oue ; but it must be 

 observed that this crop was sown broad cast ; a gjood deal was 

 destroyed by the grub, and by canary birds; and many grains, 

 laying on the surface, had not vegetated. 



The value of the ai>ove crop, rating the barley wheat at two- 

 pence per pound, anil the straw at <£5. per ton, is ^43. .4, 2. per 

 acre, which is inferior to a potatoe crop at 8s. per bushel ; because 

 200 bushels at one crop would be <£80. : yet if potatoes be rated 

 at 4 shillings, and if the advantage of obtaining manure be con- 

 sidered, the barley wheat crop will be found equivalent to that 

 of potatoes. 



The small experiment which preceded this crop was dibbled 

 on the 16th of March, 1811 ; and gave a much greater return : 

 five and one-third ounces was the quantity of seed. After the 

 produce was reaped, I inspected the stubble, and it appeared 

 that not a single grain of the seed had failed. The produce from 

 those five and one-third ounces was 135 pounds, or 2160 ounces, 

 which is 405 for one. If therefore these 2160 ounces had also 

 been dibbled, and with the same success as in the first experi- 

 ment, the result would have been 2160 x 405=874800 ounces, 

 which divided by five one-third ounces (the first seed,) gives a 

 return from the two crops of 164127 for one. Hence it is not 

 impossible, under the circumstances of the first crop, from the 

 five one-third ounces of seed dibbled on the 16th March 1811 : 

 * Because if 11 sheaves yield 48 pounds of grain, 960 sheaves should yield 4189 pounds.
