Third Operation. 

 This operation the same as the second in every respect. 



Fourth Operation. 



For every ten pounds of yarn make a clear lye from half 

 a pound of pot or pearl ashes. Pour the lye into the boil- 

 ing-pan, and add as much clear water as will be stifficient 

 to boil the yarn for two hours ; then enter the yarn, light 

 the fire, and bring it to boil in about an hour. Continue 

 it boiling about an hour, then take the yarn out, wash it 

 very welfin clear water, wring it, and hang it to dry as in 

 former operations. 



N. B. This operation is to cleanse the yarn from any 

 oleaginous matter that may remain in it after boiling in 

 the soap and dung liquors. 



Fifth Operation, 



To every gallon of iron liquor* add half a pound of rud- 

 dle or red chalk (the last the best) well pulverized. 



Mix them well together, and let the liquor stand four 

 hours, iii order that the heavy particles may subside ; then 

 pour the clear liquor into the boiling-pan, and bring it to 

 such a degree of heat as a person can well bear his hand in 

 it; divide the varn into small parcels, about five hanks in 

 each ; soak each parcel or handful very well in the abo-vc 

 liquor, wring it, and lay it down on a clean deal boar'd. 

 When all the yarn is handed through the liquor, the last 

 handful must be taken up and soaked in the liquor a second 

 time, and every* other handful in succession till the whole 

 is gone through ; then lay the yarn down in a tub, wherein 

 there must be put a sufficient quantity of lye made from pot 

 or pearl ashes, as will cover it about sjx inches. Let it lie 

 in this state about tvvo hours, then hand it over in the lye, 

 wring it, and lay it down on a clear board. If it does not 

 appear sufficiently deep in colour, this operation nuist be 

 repeated till it has acquired a sufficient degree of darkness 

 of colovir : this done, it myst be hung to dry as in former 

 operations. 



N, B. Any degree of red or yellow hue may be given 

 to the yarn by increasing or diminishing the quantity of 

 ruddle or red ch^lk.
