[Some perfons may objefl; to the above price as being too higb; 

 but I can afluie them, that they are worth more as a food for 

 hogs; befide, I have fold potatoes within the laft two years at 

 I2S. per fack, but I never before knew them at fo low a price 

 as theprefent. 



At 6s. per fack, the profit would be more than 24I. per acre, and 

 at 8s. per fack, 36I.] 



Gentlemen, 



It may be proper to remark, that 

 the field on which the above experiment was made, 

 was an oat-ftubblc in the autumn of 1783. In 

 Odlober is was ploughed, and left in a rough ftate 

 during the winter. In April, it was crofs-ploughed 

 and harrowed. 



On the 8th of May I began planting, by marking 

 out the field into beds or ridges eight feet wide, 

 leaving a fpace of two feet wide for an alley be- 

 tween every two ridges. The manure (a compoft 

 of ftable dung, virgin earth, and fcrapings of a 

 turnpike-road) was then brought on the land, and 

 depofited in fmall heaps on the center of each 

 ridge, in the proportion of about thirty cart-loads 

 to each acre. A trench was then opened with a 

 fpade, breadth-way of the ridge, about four inches 

 deep; in this trench the pctatoe fcts were placed, 

 at the diflancc of nine inches from each other; the 

 dung was then fpread in a trench on the fcts, and 

 a fpace or plit of fourteen inches in breadth dug 

 in upon them.
