favorable circumstances ; long exposure to dampness or rain darkens the

 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.
