The Hubst.ance, not the words, of thi.s article is an extract from parts of an illustrated work,

 bearing fauna of the Mississippi Kiver system has been derived in part from the Laramie sea 

 and the fresh-watei- lak-s which succeeded it, by means of the persistence of their outlets as 

 rivers, <lowu to the present time.
