TRACTS ON VARIOUS SUBJECTS, &c. 18 



an advantage is this, in a place where the scanty means of labour 

 are generally complained of! 



It will be observed, by the table of experiments, that the great- 

 est produce was at the rate of 648 bushels per acre. This was 

 from No. 5, in the division manured with horse dung : but even a 

 greater rate of produce was had from a portion of the unmanured 

 acre, which yielded the 522 bushels before mentioned. I ascer- 

 tained that 30 feet of the rows of this acre, twice repeated, and 

 taken indiscriminately, produced of lino large potatoes 52 pounds: 

 or, as will be hereafter explained, at the rate of 674 bushels per 

 acre. 



This was also greatly surpassed by an experiment upon one 

 kidney potatoe. It was cut in eleven pieces, which were planted 

 in a single row, at one foot asunder, on the 5th of April, 1810, 

 upon ground very highly manured with hog's dung. Nine 

 of the sets only came up, and these occupied one row that 

 measured nine feet. On the 8th of August, 1810, when the 

 haulm had fallen, the potatoes were taken up, and weighed 2l-§- 

 pounds averdupois ; which is in the proportion of 929 bushels 

 per acre. 



These well ascertained facts will, I hope, draw the attention of 

 the planter to the row culture ; and to establishing farm-yards, 

 and hoggeries, for the purpose of manuring their lands. They 

 might then make experiments for themselves, which I am confi- 

 dent would soon induce them to change their present modes of 

 husbandry ; because these are evidently far less profitable, and 

 must, in the course of time, infallibly exhaust, and ruin their 

 plantations. 



The spot selected for experiments is in the front garden at 

 Plantation-house. It was exactly a square chain, or the tenth 

 part of an acre ; and was, at first, divided into four equal parts
