 in various qualities, and varies in size from f inch to 

 2 inches or more in diameter, some pieces containing 

 gum in white streaks, and others hardly any, and some 

 pieces more oil than others. The best for making

 useful for tincture. The gum left when the tincture is 

 made with rectified spirit possesses adhesive properties, 

 and forms an excellent mucilage for sticking purposes.
