A gravel bank in Queen Victoria park about opposite 

 the middle of the rapids was accessible before the power 

 instalments and the park improvements and was very 

 rich in fossil shells. Professor Coleman collected fossils 

 at this locality and reports the following species: 



Gastropoda. Pelecypoda. 



Pleurocera subulare Lea Sphstrium solidulum 



Goniobasis livescens Menke S. Striatinum Lam. 



Physa heterostropha Say Unio gibbosus Barnes 



Limnffia decidiosa Say U. luteolus 



U. rectus 



U. clavus 



U. occidens 



Quadrula solida Lea 



Q. coccinea Conrad 



The Horseshoe Fall from Porter Bluff and Terra- 

 pin Rocks. 



From the top of the bluff at the southwestern corner 

 of Goat Island there is a fine view of the western part of 

 the Horseshoe fall, of the nearer part of the rapids above 

 the fall and of the bluffs back from the river on the west 

 side. The water here and for a considerable distance 

 farther out is very shallow; much of the rock is exposed 

 and the surface is dotted here and there with stranded 

 blocks of limestone. The shallows near the island is called 

 Goat Island shelf. A little above the water level, the ledge 

 of the Clinton limestone projects out about 500 feet 

 150 m.) from the extreme end of Goat island and is 

 covered with the same assemblage of huge fallen blocks 

 as at the American fall. The fine material has been washed 

 away leaving blocks that are on the average considerably 

 larger than those below the American fall. 



The view from the Terrapin rocks northward along 

 the western face of Goat island shows very clearly the 

 relation of the American fall to the cliff line, for beyond 

 Goat island and extending substantially in the same line, 

 the front of the American fall is in plain view and also 

 a part of the cliff farther north. The whole front is a nearly 

 straight line which the American fall appears not to have 

 modified perceptibly. 



The central part of Horseshoe fall and especially the 

 head or apex of the curved brink are seen here at too low 

 an angle for a clear appreciation of their outline. The 

 deep emerald green water pours over the brink in a grace- 

 ful unbroken curve. The water there is supposed to reach
