careful measurement. The small island which Carver's engraving 

 shows in the brink of the Palls, somewhat to the left of the middle, 

 was the upper end of Spirit Island, while the low island below the 

 Falls, which he represents as nearly circular and covered with trees 

 containing great numbers of eagles' nests, can be no other than the 

 lower end of the same island. If his engraving is correct in show- 

 ing two islands here, it can only be accounted for by supposing that 

 the narrow strip of limestone which constitutes the top of the island 

 had fallen down in the intervening space, and the sandstone had been 

 washed away by the river, thus causing two parts, or two islands, 

 where at first there was but one. This would necessitate the 

 placing of Carver's line of the crest of the Falls some distance
