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

 the wood of JEsculus 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 M. Hippocaatanvm occasionally has been found efficacious as a substitute 

 for cinchona bark in the treatment of intermittent fevers ( U. 8. Dispensatory, 14 ed. 1565. Sat. T>ixpcmatory, 2 ed. 

 712), and similar properties may be looked for in the bark of JE. ylalra.
