Cultivation of Arable Land Potatoes. -Produce of .Crops of. 117 



choofe as dry a time as poflible for the bufinefs ; as \vhen this fort of crop is 

 taken up wet, it is never found to keep well. After the whole of the crop has 

 been raifed from the ground, it fhould be fpread thinly upon a dry floor, and be 

 allowed fome days in order that it may become perfectly dry before it is depofited 

 in the fituation in which it is to remain during the winter. 



The produce in crops of this as well as other kinds muft vary much, according 

 to the circumftances of foil, cultivation, and feafon. It has been flated by Mr. 

 Donaldfon, to be from five to eight or ten tons, and on the average over the whole 

 kingdom about fix tons, to the Englifh ftatute acre. In Mr. Billingfiey s exten- 

 five experience in the growing of this vegetable, he appears never to have had a 

 greater produce than about a lack in a perch of ground, or one hundred and iixty 

 facks on the acre, of the eating kinds of potatoes, but he is aware that a much 

 larger produce may be obtained of thofe forts employed in feeding of cattle, 

 though he feems to think them lefs nutritious. In Yorkfhire, according to the 

 Agricultural Report of that diftricT:, from three to four hundred bufhels of 

 thofe forts that are commonly made ufe of at the table, are confidcred as a good 

 produce ; but thofe cultivated for cattle purpofes moftly yield from fifty to one 

 hundred buihels in addition.* 



In fome cafes, in the county of Kent, four bufliels are faid to have been dug 

 up from a lingle fquare rod of ground, which is at the rate of fix hundred and 

 forty bufhels to the acre; which, at the price of only one milling the bu ftiel, 

 would afford thirty-two pounds as the value of the produce.t Crops do not 

 in general, however, afford by any means fo large a profit. 



Still larger quantities have, indeed, been aflerted to have been produced
