The papers being tested were made from the following mixes of fibers:

• XB control 75 percent linen cuttings and 25 percent cotton cuttings;

• YB 50 percent linen cuttings and 50 percent cotton cuttings;

• ZB 50 percent linen cuttings and 50 percent raw cotton fiber.

The control was the normal paper composition in use for currency production at the time. Linen and cotton cuttings refer to scrap fiber obtained from textile mills whereas raw cotton fiber was fiber that had not been processed into thread.
