INDIGO. 



Letter to stroDg good quality. At present there is a preju- 

 n April 1785. dice against it for its shape and appearance, which 

 we conceive might easily be remedied, by making 

 it in square cakes of about one and a-half inch or 

 two inches, like the samples No. 2, which will 

 make it resemble and answer every purpose of 

 that which is made by the French at St. Domingo, 

 which is in high estimation. If, in forming or 

 drying the indigo, the sand and dirt which adhere 

 to the outside could be avoided, it would render it 

 more pleasing to the eye and more saleable, as 

 frequent complaints have been made that the sand 

 injures the mills in grinding it. 



73. We have, besides the large samples which 

 are numbered, selected a few particular stones, of 

 rich fine copper, marked C, and fine purple, 

 marked P, which are the qualities that will 

 always please and find a ready and good sale. 

 Low qualities we desire may be avoided, as there 

 is annually a great supply of Carolina indigo at 

 low prices, which will answer the same purposes, 

 and which, from the low freight and small expense 

 attending the importation, will always have the 

 advantage over any of the like qualities imported 

 by us.
