favorable circumstances ; long exposure to dampness or rain darkens the 

 gum, and gnarled or diseased stems produce only the inferior darker gum. 

 This gum is used in calico printing and in all other industries where a 

 mucilage is necessary. The bark of this tree as well as the pods is exten- 

 sively used in India as a tanning material, and the wood is much valued 

 on account of its hardness and durability. It may be raised from seeds.
