Leather which has been properly tanned with liquors made from chestnut or rock oak bark has been considered for generations to be the best for shoe soles. This leather has a bright light-oak color, the price ...which it brings depending very largely on this brightness and uniformity of color. As it comes from the tanning liquors leather is often quite irregular in coloring, and when made from nearly all other vegetable tanning materials it is darker in color than that tanned with oak bark. Irregularity of color is not necessarily a sign of inferiority, but, as a matter of fact, it generally indicates damage done in the preparation, tanning, or finishing of the leather, or stained or damaged places on the original hides.
