 further to the south and west it attains to a magnitude of the 

 first rate. Michaux mentions trees on the banks of the Ohio,

from twelve to sixteen feet in circumference. The wood is a* 







well known material in cabinet wt>rk, approaching mahogany in 

 its colour and qualities. Leaves alternate, smooth,.ov.al-oblohg,
