shale, Oneida-Medina rocks appearing toward the top of the 

 hill. 



East of Frankfort hill, and 5 miles southeast of Utica, is 

 Dutch hill, forming the abrupt south wall of the Mohawk val- 

 ley, with the river at its base. The steep north face of this 

 hill is terraced by stream flow held up by the ice front. Plates 

 8-12, are views of the face of this hill. No glacial drift re- 

 mains on the slopes, which are Utica shale. Plate 9 shows the 

 face of the hill as seen from the electric railway (Utica & Mo- 

 hawk Valley Railroad), near "stop 4." The highest stream 

 cutting is not visible in this view from the foot of the steep 

 slope, but is shown on plate 8. It is a bold, cut bank, some 30 

 to 40 feet high, facing a gently sloping terrace some 40 rods 

 wide. The altitude of the angle or notch of the cutting is 

 nearly 1000 feet. About 150 feet below the highest cut is an 

 indefinite bank, indicated in plates 9, 10, by the banks of snow 

 near the sky line. The lower and stronger bluffs are shown in 

 these plates, the higher being at about 700 feet and the lower 

 about 540 feet. 



East of " stop 4 " is a landslip on the face of the lowest bluff, 

 that occurred in the spring of 1903, a few weeks before the 

 photographs reproduced as plates 9, 11 were taken. This is 

 significant in this connection, as showing the character of the 

 hill slope and the entire absence of drift. The slide was pro- 

 duced by a veneer of the rotted shale slipping on its bed. Near 

 the top of the steep slope is a hummocky belt, below the banks 

 of snow shown in plates 9, 10, which is the product of old 

 landslips. 



The northeast face of Dutch hill is cleft by a deep notch or 

 ravine. The eastern portion of the steep face of the hill shows 

 from the base only two conspicuous bluffs, the two lower ones 

 of the west end of the hill being eastward united into one. The 

 union of channels toward the east is similar to that on the 

 Frankfort hill. 



The reader who is able to visit the locality (even a ride on 

 the New York Central or the West Shore Railroads is suffi- 

 cient) should observe the difference between the profiles of
