water almost covering the surface ; and others only par- 

 tially lifted from the parent rock, waiting for another con- 

 vulsive effort of the torrent to detach them and give 

 them an erratic character. In short, one sees in such 

 streams, a cause fully adequate to the production of those 

 numerous boulder stones that are scattered over the coun- 

 try : I mean a cause sufficient to detach and round them. 

 Probably, however, the expansive agency of water, frozen 

 In the seams of rocks, contributes not a little to lift them 

 out of their original beds.

ART, VIII.— ENUMERATION OF PLANTS GROWING SPON- 

 TANEOUSLY AROUND WILMINGTON, NORTH CARO- 

 LINA, WITH REMARKS ON SOME NEW AND OBSCURE 

 SPECIES. By Moses A. Curtis, A. M. Communicated, Sep- 

 tember 3j 1834.* 



The desirableness of local catalogues of Plants as 

 directories to the collector, and their importance to the in-

 that they will be multiphed until definite localities are

established for all the American species. The only Cata- 

 logues including local Floras, of which I have any know- 

 ledge, are the following : 

 ' 1. Flora of West Chester County, Fenn., by Dr. Dar- 



lington. 



2. Florula Bostoniensis, by Dr. Bigelow.
