44 Process for Dyeing Turkey Red. 



Under this tub is another to receive tlie ley, and pure 

 water is repeatcJlv passed through the iirst tub to form leys 

 of different strength, which are kept separate at lir*t until 

 their strength is examined. The strongest required for use 

 must swim or float an egg, and is called the ley of six 

 decrees of the French hydrometer, or persi'/i(jt/eiir. 

 The weaker arc ai'ter^\ards brought to this strength by 

 passing them through fresh barilla; but a certain quantity 

 of the weak, which is of two degrees of the above hydro- 

 meter, is reserved for dissolving the oil, the cum, and the 

 salt, which arc used in subsequent parts of ihc process. 

 This ley of two degrees is called the weak barilla liquor; 

 the other is called ihe strong. 



Dissolve the pearl-ashes in ten pails, of four gallons each, 

 of soft water, and the lime in fourteen pails. 



Let all the liquors stand till they become quite clear, and 

 then mix ten pails of each. 



Boil the cotton in the mixture five hour.^j then wash it in 

 running water and dry it. 



Step 11. — Bai/ilifi, or Gray Sfeep. 



Take a sufficient quantity (ten pails) of the strong' barilla 

 water in a tub, and dissolve (»r dilute in it two pailsfuU of 

 sheep's dung; then pour into it two quart-bottles of oil of 

 vitriol, and one pound of gum arable, and one pound of sal- 

 ammoniac, both previously dissolved in a sufficient quantity 

 of weak barilla water ; and, lastlv, tweniy-five pounds of 

 olive oil wiiich h.ts been previously dissolved or well mixed 

 with two pails of the weak barilla water. 



The materials of this steep being well mixed, tramp or 

 tread down the cotton into it until it is well soaked : let it 

 steep twenty-four hours, then ring it hard and dry it. 



Steep it again twenty-four hours, and again wring and 

 dry it. 



Steep it a third time twenty-four hours, after which 

 wring and dry it; and, lastlv, wash it well and dry it. 



Step III.— 7'Ae fFfiiie Sfeep. 

 This part of tlie process is precisely the same with the 

 last in cverv particular, except that the sheep's dur.g is omit- 

 ted in the composition of the steep. 



Step IV. — Gall Sleep. 



Boil twenty-five pounds of galls, bruised in ten pails of 

 river water, until four or five are boiled away ; strain the 

 liquor into a tu'j, and pour cold water on the galls in ihe 

 ■jtraiucr to wash out of them all their tincture.
