Remarks upon the Journey of André Michaux to the high

(Am. Journ. Sci., xxxii., Pp. 466-473. 
During last season Prof. Sargent explored the head waters 
of the Savannah River with the main object of finding Michaux’s 
station for Magnolia cordata and to determine the character and 
geographical distribution of this doubtful species. It is interesting 
to follow the progress of Michaux and his Cherokee guide as given 
in his Journal, and trace with Prof. Sargent 98 years later the 
course taken, and furthermore to find the same trails, and the 
same plants still in existence. He was able to identify the little 
“arbuste,” with “feuilles denticulées” as Shortia and to obtain it
