INDIGO. 



jLetterto inferiority of which will be apparent, if they be 

 6 June 1810, Contrasted with any of the samples of good indigo. 



Indigo which is in any degree mixed with weak, 

 or, as they are most commonly called, milky stones, 

 will sell at low prices, for the following reasons: — 

 the exporters will not buy it, and it is not suffi- 

 ciently strong for the purpose of dyeing woollens, 

 which is the principal consumption of indigo in 

 Great Britain. From a want of proper informa- 

 tion on this head, it has been stated by a ^ery 

 respectable house here, that the indigo marked G 

 and that marked N were exposed for sale to the 

 Company at Calcutta at the same time, and the 

 difference of price asked was only equal to three- 

 pence per pound. The indigo marked N was 

 taken, which in this market is worth about 5s. 9d. 

 per lb. ; and that marked G, one chest of which 

 has been sold at the sale for 13s. 6d., was rejected: 

 but it is to be remarked, that the average sale 

 price of the lowest parcel was 7s. Id. per lb. 

 Fine indigo should be light, tender, clean-textured, 

 rather of a red (but not a coppery) hue, which the 

 buyers here term strength. We have also speci- 

 mens of dull purple (sample N), and likewise of 

 dull violet (sample P), which will not suit this 

 market, as they produce very low prices. All 

 mixed indigos should be avoided ; by which w^e 

 mean, when there is to be found in the same chest 

 indigo of good, weak, and dull kinds. Good pur- 

 ple and violet may be altogether, and so may good 



violet
