_American Indigoes_. _Guatemala_.—These indigoes are produced now altogether in Hunduras, although they still retain in commerce the name of Guatemalan. They are generally found in small pieces, irregular in form and size, and come in envelopes of skin containing about half as much as the Bengal chests. Putting aside the difference in exterior form, these indigoes approach very closely to those of Bengal. The same qualities are found, only they are more frequently mixed. The clear blue is more rare, and, when it is found, it is poorer in coloring matter. In purchasing these indigoes it is necessary to beware of the reds, which often contain a strong proportion of the brown extractive matter. It is not rare to find among the Guatemalan indigoes beautiful specimens of the blue violet, equal to the richest Bengal variety. Unfortunately, this superior variety is generally mixed with inferior kinds, as to have less value. The American indigoes are classified as follows:— _Guatemala floro_.—Bright blue, paste uniform, soft and light. This variety, in Bancroft’s time, was the most esteemed of all indigoes. _Guatemala sobresaliente_.—Less light, the paste firmer and the blue less beautiful. _Guatemala corte, or copper-colored_.—Paste less firm and heavier, coppery red. _Caraccas_.—These resemble very much the Guatemala varieties. The qualities are designated by analogous names, but they are, in general, less esteemed than the preceding. _Mexican_.—They hold an intermediary rank between the Caraccas and Mexican. _Brazil_.—These indigoes are in small rectangular parallele-piped masses, or in irregular lumps of a greenish gray color externally, and having a smooth fracture, a firm consistency, and a copper-colored tint of greater or less brilliancy. _The indigoes of Africa and Egypt_.—These have only been manufactured within the last twenty years; they are in flat squares. The paste is fine and quite light, and the color pure blue or bordering on violet. The varieties are distinguished as fine blue and good violet and red. _Indigoes of the Isle of France and Senegal_. Rare in commerce, but of good quality.
