hours; tread it well, until all the yellow matter has heen worked oititj^ 

 examine it at the expiration of the ahove time, to see whether it has 

 lost all its yellow coloring matter; if it has not, immerse it a few 

 hours more into the water; this being done, take it out, put it into a: 

 vat, and pour six buckets of river water upon it. 



This being done, dissolve one pound fourteen ounces of potash in 

 Water, and pour the clear part of this liquor on the safflower in the tub; 

 mix it well, and set it by, in a cool place, for six hours. At the expi- 

 ration of this time, take out the safflower with its liquor, run it through 

 a sieve into a vat, pour half a bucket of water upon it, and press it 

 out, in order to extract all the coloring matter therefrom; pour fifteen 

 quarts of vinegar, and three-eighths of an ounce of oil of vitriol into 

 the liquor; then take the ten pounds of silk, fix it upon rods, put it. 

 into this safflower liquor, and Avork it well therein, for the space of 

 four hours; then take it out, rinse it in running water, wring it well, 

 and lay it aside for further use, in its wet state. 



Lastly. Dissolve four ounces of cream of tartar in river water, and 

 pour the clear part of this solution into a tub, with eight buckets of 

 river water; immerse the silk, which has before been colored to a 

 light red, in this solution, and work it well therein for a quarter of 

 an hour; take it out, wring it and dry it, and you will have a hand- 

 some pink. 



Note. — For a pink of a liiglier color, take an additional quantity of safflower; and 

 for a lighter, take less than the above prescribed quantity. It will likewise be of 

 benefit to add a small quantity of vineg-ar. Lemon juice, however, is unnecessar)', * 



A high-colored Crimson. 



Take \\ lb. of cochineal, 

 1 lb. of galls, 



4 otinces of cream of tartar, and 

 2h lbs. of Roman alum. 



Dissolve two and a half pounds of Roman alum in a kettle, with 

 ten buckets of water; pour the clear part of this solution into a vat, 

 immerse the silk in it, and work it wetl therein for the space of four 

 hours; then take it out, and rinse it in running water, wring it, and 

 lay it by for further use, in its wet state; then put in a kettle containing 

 eight buckets of boiling water, the following articles: 



One and a quarter pounds of finely powdered cochineal, one pound 

 of finely powdered gall-nuts, and four ounces of cream of tartar. Let 

 the whole boil slowly, for the space of fifteen minutes; cool it with 

 two buckets of water, work the silk well in the liquor, which must h& 

 kept in a continual boil, for the space of one hour and a half; then take 

 it out, rinse it, wring it, and let it dry, when the dying will be com- 

 pleted. 



* Dr. Cooper says that lemon juice is essential to bring' out the pink color of saf- 

 flower, by neutralizing the alkaline liquor in v/hich the plant is steeped.
