The objectionable brown color of its solu tion can be removed by filtering through animal charcoal, but its adhesive properties, as indicated by its viscosity, are only equal to those of a. Third-rate gum arabic. It is used to form the adhesive surface of postage-stamps, labels, and envelo es.

Other gums are also largely im orted for the uses to which gum arabic was almost exclusive y used. Of these the principal ones are the other African gums from Senegal and the Cape, and the Ghatti gums from India.
