Anotations

Scope note:

Wood from the species Aspidosperma quebracho-blanco. It is very hard, yellow in color, heavy, and well suited to bending and shock. If the drying process is not slow, the wood will crack. It is used for floors, carts, wheels, tool handles, furniture, chess pieces, and skis. In some places it is used as fuel because it burns slowly and does not produce sparks or large amounts of ash.
