Esther Singleton, The orchestra and its instruments (1917)
“ The stick of a violin bow is made of Brazilian snake wood, or lance wood, reddish and slightly mottled. It is cut straight, following the grain of the wood and then it is slightly bent by the application of heat. The hair, fastened into the tip by a plug, is inserted into the nut of the bow (made of ebony, or tortoise shell) ; it can be made tighter, or looser, by turning the screw in the nut. There are from 175 to 200 hairs in a bow and these are taken from tails of stallions. White hair is used for the violin, viola and violoncello and black for the double-bass. ”
