which have come from the Canadian highlands, and rolled fossils and 

 foesiliferous limestone from the Trenton and Hudson groups in Canada. 

 These foreign elements in the Drift, as I have explained elsewhere, were 

 doubtless brought by glaciers or icebergs, and were deposited on the sum- 

 mit or slopes of the water-shed. They were subsequently transported by 

 the current of the ancient Tuscarawas to the localities where they are 

 now found, and where they are mingled with rolled masses of the neigh- 

 boring rocks.
