The larger number of the species in the last list are, of course, more 

 or less local, but it is believed that every one of them, and also those of 

 the two i^receding lists (excepting, perhaps, Ulmus alata, Quercus fal- 

 cata, Q. nigra, and Q. sfellata, which prefer poorer soils), could be found 

 on an area of less than a square mile in extent, commencing at the bank 

 of the Wabash Kiver, immediately above the mouth of White Biver, and 

 extending back through t]ie cypress swamp to the bluffs which border 

 the bottom lands. This gives for one square mile of woods, a grand 

 total of more than 70 species of trees, not including several of the larger 

 shrubs (as Amorpfha fruHcosa and Ilex verticillata), which here attain 

 almost the stature of trees.
