No. 1 has been quarried quite extensively just below Ste- 

 ven' s Point, and used in constructing the piers of bridges 

 along the Jefferson Branch R.R.; is of a bluish green color, 

 very hard and contains much olive shale in small fragments 

 scattered through the coarser portions of the stone. 



In No. 2 should be found a considerable quantity of red 

 shale, but as it is all concealed nothing certain is known con- 

 cerning its character. 



Nos. 3-7 of the above section are seen at the narrows, one 

 mile below Stevens' Point, where the creek having left its 

 ancient channel has cut a new one between vertical walls of 

 No. 7, in a canon-like gorge. 



Clay moraine and new channel — The reason of the new 

 cut is obvious, for just north of the present channel we find 

 75' of a tough impervious reddish drab clay dumped down 

 right across the old channel, and it was doubtless the cause 

 of the change in the creek's course. The clay doubtless 

 owes its origin to Glacial agencies ; it is now manufactured 

 into brick, is quite fine and homogeneous, not a pebble or 

 bowlder of any kind being seen in the 40' exposed in the 

 R.K,. cut. 



No. 7 lies in rather massive layers and has been quarried 

 to some extent near the chair factory ; has a dark olive color, 

 and exhibits no current-bedding, so common in No. 1 and 

 the Catskill sandstones above.
