 ifpofed within four, five, or fix inches of one another ; coverin 

 the banks, as we obferved in the other method. The plants, Bailed in ti manner, 

 are obferved to anfwer as well, or rather better than the others ; but they 

 more care and attention in the weeding: the diftam es muft be, however, varied"

ac- 





cording to the fort you cultivated; thefe being the muft commonly ufed for the 

 firft fpecies. The plants grow to full perfection in two or three months ; and are 

 generally obferved to anfwer beft, when cut in full bfoftbm. 



Your feeds being thus fowed, your next care mud te to fee that the works be 

 ready, and in good order; well cemented, terraffed, and feafoned. Thele confift of 

 three or five fquare citterns, or vatts, made gradually fmaller : and fo fituated on the 

 fide of fome riling 





round, as to have the plain at the top of the fecond and third 

 upon a line with the bottom of the firft, or a little lower ; and the plain at the top 

 of the fourth and fifth, upon a line with, or lower than, the bottom of the fecond 

 nd third. The firft, which is the 



a 



Jargeft and called the deeper, is generally 



znade about eight or ten feet fquare, by four deep; and opens into the fecond, or fe- 

 cond and third, by one or two round holes, made clofe to the bottom ; fo as to dif- 

 charge all the tincture readily : thefe generally run through a log of fome hard tim- 

 ber, placed for that purpofe, in the wall; which is fometimes bored witn two or 

 three holes, placed one over the other, or triangularly; to difcharge the liquor with 

 the greater fpeed. The fecond, or fecond and third vatts, called the beaters, are 



made of different dimenfions; according to the method intended to be u fed in beat- 



ing or working of the tincture: for if you have but one ciftern, and intend to work 

 up the liquor with hand-buckets; it mould be eight or. ten feet fquare, and fix, or 

 iix and a half deep: but if you have two cifterns, and intend to beat your tinc- 



ture with an engine; they fhouid be fo deep as to hold all the liquor a good way 

 below the main, or horizontal axis, into which the buckets are fixed ; and the walls, 





in thofe cifterns, fhouid be nearly as high over the rollers, as the ciftern is deep 

 below them ; to keep the tincture from being wafted. After the liquor is well beat 

 in thefe cifterns, it is left to fettle; and when the pulp is deposited, the clear in- 

 cumbent fluid is drawn off by a convenient vent, placed fome inches above the bot- 

 tom of each ciftern ; and the remaining magma diicharged into the fourth and fifth 

 cifterns, by convenient outlets, placed clofe to the bottom; like thofe in the firft. 

 Thefe laft cifterns are but fmall ; they are, however, generally made fquare, and pro- 

 portioned to the quantity of pulp fucli works commonly produce at a time. 



The beft et r ,inc 1 have ken for beating of Indigo, was built in the following 

 form, viz* In the intermediate fpaee between the two beaters or main cifterns, 

 and in the middle of a line drawn through the center of both, you raife a main 

 column; which is fixt fo as to move with a point, or pivot, lodged upon a ground- 

 fil, at the bottom; and fecured with a convenient frame at the top; where it alio moves 

 by a pivot, in a beam, or timber that runs from the upper part of the wall of one 

 of the beaters, to the oppofitc wall of the other. This column is fupplied, below 

 the center, with a pair of arms, by which it is turned round; and, over this, it is 

 alio furnifhed with a wheel, well fupplied with coggs, fixed fo as to rife in a perpen- 

 dicular direction to the plane of the wheel : thele, as the main column turns round, 

 work either or both the horizontal rollers, into which the buckets are fixed ; and 

 which are fo contrived, at the ends adjoining to the main column, as to be wedged 

 higher or lower, at pleafure ; fo that one, or both, may work as need requires. Thefe
