There are three kinds of gum wood - sweet or red gum, sour or black gum, and cotton gum. The former is the only one used for interior work. When quarter cut, it resembles Circassian walnut so closely that these two woods are frequently used together in furniture. Plate CXXVIII shows the interesting dark streaks running through this wood. Sweet or red gum is close grained and does not require filling. It can be stained walnut or mahogany effectively by using specification 9. This wood is frequently treated natural, and when quarter cut, its grain produces effects equal in beauty to many more expensive woods. - Specification 13 gives the natural finish. White enamel can be produced satisfactorily over gum wood.
