^ WATERINS HEMP. 



The handfulls of fteeped and cruftied hemp which are in- 

 tended to be beaten and Gripped dry rouft alfo be expofed on 

 the grafs ; this operation being ablDluteiy neceffary to whiten 

 the tow, and facilitate the feparation of the reed. 



§ II. 



Becapitulation of t}}e Experiments. 

 The experiments 3y means of a portable (leeping velfel, different quantities 

 afcertantht ^^ hemp wcre fteeped, the temperature of the foapy liquor 

 rci^ujfite was varied at pleafure, and the (late of the hemp was obferved 



^ during the ^jourfe of each operation, of which the duration 



was more or lefs prolonged, in order to afcertain ; 

 Tempereture, 1 ft. The temperature which the foapy liquor ought to have 



before the immerfion of the hemp ; 

 time, tn4 2nd. The lime neceflary for a complete fteeping, at a de- 



terminate temperature; 

 ■proportiou of 31-d. The quantity of foap abfolutely neceffary for a given 



•fO»P* weight of hemp-ftdlks, weighed before the immerfion, &;c. 



P.efult* or From a great number of experiments made in the months of 



general obferva- January, February, and March lart, it was found, 



tions on the n ^1 • • 1 • r r 1 - r^ » 



proccfs. ' 111. J hat yi'ater contaming the quantity of green loap directed 



' by M. Bralle, for a given weight of hemp, effects the lieeping 



completely ; 



2nd. That tlie fteeping is fo much the more fpeedy as the 

 temperature of the fluid is nearer to ebullition, at the time of 

 the immerfion of the hemp ; 



3rd, That if the hemp be kept more than two hours in the 

 Sleeping veffel, the time prefcribed b) IVJ. Bralle for obtaining 

 a complete watering, the tow feparates equally well from the 

 reed, but it acquires a deeper colour, and Ipfes part of its 

 flrength ; 



4lh. That if the hemp be immerfed in a cold foapy liquor, 

 ^nd heat be then applied, the lieeping is not j^ccomplidied 

 fo perfedly, whatever degree of temperature may be given 

 to the liquor, and however long the immerfion may be con- 

 tinued * ; 



5th. That the bundles of hemp immerfed and kept vertically 

 jn the veffel, are ftecped more uniformly than if they were 

 Vid Horizontally ; and this pofition alfo facilitates the manipula- 

 tion. 



♦ Probably the fluid between the fibres is not heated, becaufe its 

 Condu£ling power is bad, and it is prevented from circulating. N.
