RUBBER BOOTS 



can be patched as follows: Rub the patch and boot thor-

 rubber five times, every time letting them dry. Do this 

 once more, and, before they dry, apply the patch, with 

 pressure, if possible, and the boot is mended. If liquid rub- 

 ber is not obtainable, dissolve small pieces of rubber, not 

 vulcanized, in warm spirits of turpentine to the consistence 

 of molasses in summer.

TO KEEP GUM ARABIC FROM MOLDING. 



Solutions of gum arabic soon mold and sour, and finally 

 lose their adhesive property. It is said that sulphate of 

 quinine will prevent this, while it imparts no bad odor of its 

 own. The addition of a solution of a few crystals of this 

 salt to gum arabic will prevent the formation of mold quite 

 as effectually as carbolic acid, and by analogy it is safe to 

 suppose that the same salt could be used in writing ink, 

 mucilage, and possibly glue.
