A SUPERIOR GLUE (WATERPROOF).
A very superior article may be made by dissolving 3 parts of india rubber in 30 parts of naphtha; heat and agitation will be required to effect the solution; when the rubber is completely dissolved, add 64 parts of finely powdered shellac, which must also be heated in the above mixture until all is dissolved. This mixture may be produced in sheets like glue by pouring it while hot upon plates of metal, where it will harden. When required for use, it may simply be heated in a pot till soft. Two pieces of wood or leather, joined together with this glue, can scarcely be sundered without a fracture of the parts.
