did not increase uniformly, but was slightly greater along the axis 

 of the Highlands. To determine this point definitely requires a 

 large number of accurate terrace measurements. The following 

 are the number of terraces noticed at the different localities : 



Athens 2 



Port Ewen 2 



Cornwall 2 



Haverstraw 2 



Stony Point ; 3 



Peekskill 1 and 2 



Fishkill 2 



Storm King 2 



Schodack 2 



The shore-line of the upper terrace is generally some distance 

 back from the river. In fact, as we go up the river, especially 

 above Port Ewen, the shore-line recedes. At Port Ewen the 

 terrace is 207 feet, but it is fully 225 feet at the base of Hussey 

 Mt, which was an island in the estuary. The terrace extends up 

 the Walkill valley several miles.* It seems not improbable 

 that a shore line of this Quaternary deposit will be found along 

 the base of the Catskill Mts, or not far from there. At Coey- 

 mans Landing the terrace is 140 feet, and it rises to 177 feet at the 

 W. S. R. R. station, about a mile from the river, then a hill hides 

 the further continuation of it from view. 



From Catskill up to Albany the terrace at most points is very 

 wide. At Coxsackie it extends behind the hill to the south of 

 the town, and comes down along Murder Creek to Athens. From 

 Albany an alluvial plain, belonging to this formation, spreads 

 westward, reaching a height of 360 feet near Schenectady. The 

 surface of these terraces is usually a loamy soil of much agricul- 

 tural value. 



Following up Croton River as far as Croton Lake, remnants of 

 terraces are seen afc various points, their height above the river bed 

 decreasing as we recede from the Hudson. The majority of these 

 detached pieces seem to belong to a terrace formed at the same 

 time as the 100-foot one at Croton Landing. There are at a few 

 places traces of a second and lower terrace, and besides this a 

 third one, being formed by the river during its floods at the 

 present day.
