quarters of an hour; pour it through a sieve into a vat, steep the silk, 

 which has been saturated in the foregoing liquor, composed of alum, 

 sugar of lead and chalk, in the quercitron liquor, and work it well 

 for the space of an hour; then take it out, rinse, wring, and dry it. 



If you desire a higher colored citron yellow than the above, add 

 another pound of quercitron to the above quantity, and proceed in the 

 following manner; 



Saturate the silk, as above directed, in a liquor of alum, sugar of 

 lead and chalk; then take a kettle with eight buckets of water, boil 

 two pounds of quercitron therein, for the space of three quarters of an 

 hour, and pour the liquor through a sieve into a vat; steep the silk, 

 and work it well therein for the space of two hours; after which, take 

 it out, wring and dry it. This will have given the silk the best of 

 grounds for a good yellow color. After this, take another kettle with 

 eight buckets of water, put into it two more pounds of quercitron bark, 

 and boil it for the space of three quarters of an hour: then pour it 

 through a sieve into a vat, and work the previously colored and dried 

 silk in the same, for the space of two hours; then take it out, rinse, 

 wring, and dry it. 



€^ high-colored and deep Citron Yelloio. 



Take W lb. alum, 



3 oz. of sugar of lead, 



1^ oz. of chalk, and 



8 lbs. of French berries. 



Dissolve in a kettle which contains eight buckets of water, one 

 pound and a half of alum, pour the solution into a vat, or, which is 

 better, into a cask,* and let it cool. Put into it three ounces of sugar 

 of lead, stir it well with a rake, add one and an half ounces of finely 

 powdered chalk, and stir the whole well again; and continue the stirring 

 every hour, for twelve hours. But, after the last stirring, the rake 

 must be taken out of it, to prevent the sediment from being disturbed, 

 and then let it stand twelve hours. At the expiration of this time, 

 draw off the liquor; but be careful not to disturb the sediment, which 

 would otherwise create stains that are difficult to remove; pour the 

 liquor, thus drawn off, into a vat, work the silk well in it for the space 

 of four hours; after which, take it out, wring and dry it; then moisten 

 it with warm water, rinse it in running water, wring it, and lay it by 

 wet, for further use; then take a kettle with eight buckets of vv'ater, 

 and at the same time bruise eight pounds of French berries in a mor- 

 tar; put them into the kettle, and let them boil for half an hour; then 

 take out the liquor, and run it through a sieve into a vat. Steep the 

 silk in the liquor, and work it well therein for half an hour; take it 

 out, wring and dry it; this will produce a handsome citron yellovr. 



• This cask must l^ve a spicket, about a hand's breadth from the bottoir.. for th« 

 purpose of drawing oft' the liquor.
