ROLAND M. HARPER 



time of my visit the native vegetation was being converted into 

 baled hay and shipped away by rail at a rapid rate. This has 

 probably been going on for years, and although it may not have 

 much permanent effect on the composition of the vegetation, any 

 more than similar operations on the natural meadows of New 

 England, it certainly spoils the botanizing for the time being. 



The elongated depressions or dry channels above mentioned 

 are well wooded with oaks, which seem to be mostly Quercus 

 palustris; and other oaks, mostly Q. stellata, make scattered 

 clumps in the level prairie. Comparatively few of the shrubs and 

 herbs could be identified from the train, and the list given in 

 Table B is based on observations at close range, made while 

 walking out from Hazen and back.
