cominou with that of the other species of the genus in the manufacture of woodenware, artificial limbs (for which 

 the wood of ^sculus is preferred to that of all other American trees), paper-pulp, wooden hats, less commonly for 

 the bearings of shafting and machinery, and occasionally manufactured into lumber. 



The bark of the allied old world species ^. Hippocastanum occasionally has been found eflScacious as a substitute 

 for cinchona bark in the treatment of intermittent fevers ( JJ. S. Dispensatory, 14 ed. 1565. Wat. Dispensatory, 2 ed. 

 712), and similar properties may be looked for in the bark of jE. glabra.
