Walter M. Gibbs, Spices and How to Know Them
“ When mixed with the bark of the prunings and with those sticks which do not peel well it is known as chips. It brings a low price on the market and is used for grinding; and, although it does not have the delicate flavor of the quilled, what is lacking in delicacy is made up in pungency and, therefore, in many cases, it is preferred. Chips bring so low a price in the market that they may be purchased by the miller of spices and sold in the pure powdered state at a price much below what he can sell the bark at. ”
