XXII E x . On the river road, about two miles south of Milford Centre, 

 or one-half mile north of Colliersville, are bluish shales by the side of the 

 highway. This exposure is eighty feet higher than the Delaware and Hudson 

 railroad at South Milford. Most of the rock consists of thin, blue, arenaceous 

 shales, like those of the Sherburne formation, although a few fossils, small 

 specimens of Spirifer mucronatus (Con.), Bill., and two imperfectly preserved 

 specimens of Ohonetes scitula, Hall, were found. On the hill to the north- 

 east of South Milford, in the edge of Maryland township, are exposures of 

 the Sherburne sandstones some 140 feet higher than the South Milford 

 railroad station. 



XXV E\ Crossing the Susquehanna river at Portlandville, the line of 

 division between the Hamilton and Sherburne was followed northeasterly along 

 the western slope of the steep Crunihorn mountain. About one and one-half 

 miles southeast of Milford, and below the corner of the road for Crunihorn 

 Lake, are ledges of rather coarse, arenaceous Hamilton shales on the side of the 

 hill, perhaps 150 feet higher than the river. These shales contain a character- 

 istic Hamilton fauna, as may be seen from the following list:
