A resume of the paper read at the annual meeting of the Geological 

 Society of America, December, 1 909. The editorial comment states that 

 it " Should be considered as an additional chapter to Spencer's * Evolution 

 of the Falls of Niagara,' wherein the work of the smaller cataract and 

 the relative efficiency were scarcely considered."
