List of trees attaining a height of 100 feet or more in the Lower Wahash Valley. 



In addition to the above there are several other trees large specimens 

 of which have not been measured, but which, with scarce a doubt, occa- 

 sionally, at least, reach 100 feet in height, thus rendering it very prob- 

 able that in reality about fifty species attain this elevation. These spe- 

 cies are the following : 



* 1. Magnolia acuminata. 

 2. Tilia heterophylla. 



* 3. Eohinia pseudacacia. 



4. Frunus serotina. 



5. Fraximis pubescens. 



6. Fraxinus sanibucifolia. 



7. Fraxinus viridis. 



8. Geltis mississippiensis. 



9. Carya porcina. 



10. Carya sulcata. 



11. Qucrcus micliauxi. 



12. Qiiercus falcata. 



13. Quercus lyrata. 



14. Quercus stellata. 



* 15. Castanea vulgar is^ americana.

 by the writer.
