3^4 Mr. Henry* s Conftderations on different Maferiah, 



operations, will be about eight gallons, and is to 

 be preferved to be ufed in the fourteenth 

 operation. 



The eighth operation confifts in heating the 

 third barilla liquor, amounting to fifty-two 

 gallons, to about the warmth of new milk j re- 

 moving it, when thus warmed, from the copper 

 to a tub, immerfing the whole of the cotton 

 therein, and fufFering it to remain for twelve 

 hours, or longer. It is then to be taken out, 

 and laid on a cloth fpread on four or five fticks, 

 placed acrofs a large tub, into whic%the liquor 

 drains, as it runs from the lotton. ""The cotton 

 is then to be well wung, and afterwards 

 thoroughly wafhed, that no loofe oil may 

 remain, which would be injurious to the next 

 operation. 



The wringing tub and peg are, now, to be 

 well wafhed, and a frefh fet of poles ufed ; for if 

 any oil were to come into contaft with the 

 cotton, in the next parts of the procefs, it 

 would rccive a blackifti tinge in the dying. 



The galling forms the ninth operation. — Six- 

 teen pounds of galls, or if the blue galls be ufed, 

 a fomewhat fmaller portion, are put into twenty- 

 four gallons of water, nearly boiling. The 

 liquor is then brought to boil, and the ebullition 

 continued for fifteen minutes. But as foon as 

 the boiling commences, the fire fhould be with- 

 drawn ; as the heat already received, will keep
