Marten, Stone.-Size and quality similar to the baum; the colour, however, of the underwool is a stony white and the top hair is very dark, almost black.
The tails have also been worked, in the manner explained with regard to the baum marten, as sets of trimmings and in other forms. Stone martens are found in Russia, Bosnia, Turkey, Greece, Germany, the Alps and France.
The baum and stone martens caught in France, the north of Turkey and Norway are of the same family, but coarser in underwool and the top hair is less in quantity and not so silky.
This is also of the marten species and has been frequently offered, when dyed dark, as have baum and stone martens, as Russian sables.
