A new natural dye product, termed "Algarrobin," obtained from the wood of the carob tree, Ceratonia siliqua, found in the Argentine, has recently been placed on the market. According to a report of the United States Consul- General at Buenos Ayres, it is largely employed in the Argentine for dyeing khaki cloth for military purposes, and some quantity is also being imported to the Continent of Europe. It is said to dye the textile fibres a light brown colour, though if these be previously mordanted, more varied shades may be obtained. As it acts also as a mordant for the Coal Tar colours, it would appear to be a tannin, and may indeed be allied to ellagitannin, as its name suggests (cf. Algarobilla, loc. cit.).
