 count of the well proportioned head it forms, and the beauty of its foliage. It is 

 claimed that it is also a fever tree, i. e. When growing it absorbs so much water as to 

 render malarial districts heathful. In the northern States sugar is manufactured 

 from its sap.

 high winds.

 upland and is used sparingly for a shade tree.
