marks of glacial action on their summits or indeed on tlieir 

 sides above an elevation of 2200'. 



No. 1 is a rather coarse, very hard, and massive, current- 

 bedded sandstone. It caps the summit of North Knob in a 

 bold line of cliff outcrop and has protected it from erosion. 

 This stratum underlies the Carboniferous conglomerate No. 

 XII by about 900', according to my identifications. 



The Mt. Pleasant conglomerate is quite a prominent rock 

 in this series ; it forms a long line of cliffs around the sides 

 of both knobs and is a conspicuous object from a great dis- 

 tance. The stratum is mostly a coarse sandstone, but near 

 its base is a layer 4' to 6' thick, containing quartz pebbles of 

 a reddish or rose color ; there is also often a calcareous layer 

 at the base of the rock. 



Nos. 8 and 10 make conspicuous bluffs and cliffs around 

 the hills ; each has a layer of calcareous conglomerate or 

 brecciated impure limestone at its base, but the lower one 

 No. 10 is most massive, forming a huge black band of out- 

 crop as far as the eye can reach. Some quartz pebbles oc- 

 cur in the calcareous layers here. 



Nothing is seen of the massive white sandstones which 

 usually come 200' below the Cherry Ridge Limestone ; but 

 as everything is concealed by a deep covering of debris at 

 that horizon, they may be present nevertheless. 



No. 14 is a rather dark sandstone, and contains irregular 

 masses of calcareous breccia. 



This section ends just across the south line of Herrick, in 

 Clifford, and the lowest portion is undoubtedly in the New 

 Milford sandstone group, most probably near the top of it. 



The Cherry Ridge limestone is seen all along the western 

 range of this township at an elevation varying from 1950' to 

 2000' A. T., and it is usually accompanied by a duplicate 

 mass of almost the same quality and appearance at the base 

 of the Cherry Ridge conglomerate 50' to 60' above it. 



The surface of the ground is often strewn thickly with 

 huge black bowlders from these strata which have been torn 

 off and transported by glacial action. 



In many portions of this township at an elevation of 2000' 

 A. T. there are abundant evidences of glaciation, in the
