          called "Peruvian", that is a substitute for Peruvian Bark. Without 
 flowers or fruit I could not decide positively on its character 
 but I have little doubt that it is a Prunus or Cerasus and most 
 probably C. Pennsylvanica, which however I have never seen, and 
 no one has indicated as growing so far to the southwest. I send 
 you a single leaf, you may perhaps be able to decide from that. 
 Should like to have a specimen of C. Pennsylvanica from the 
 north.


 I have one more plant with fruit, but without 
 flowers, of which I have found no description, but will study 
 it a little more fully before writing further on the matter. 


 Have you a copy to spare me of Grays article on 
 the Botany of the Mts [Mountains] of No. Ca. [North Carolina] in Sill. [Silliman] Jour. vol 42?


 We had a spendid display of the Aurora here 
 on the 29th Sept.  I published an account in one of our papers which 
 I could send you, but do not know that you are especially intereted 
 in the subject. Was it not seen at the north? The papers 
 give us no account of it that has reached me. 


 Very sincerely yours
 Lewis R. Gibbes.
