GEOLOGY OF THE CONNECTICUT VALLEY DISTRICT. 3OI 



velopraent of the peculiar conglomerate seen back of Barber s, in numer- 

 ous embossed ledges. At the mill above the pond this conglomerate 

 dips 80° S. 62° E. 



North of Young's pond the boundary between the slates and schist is 

 very irregular, on account of the uneven erosion of the former resting 

 like a blanket upon the latter. A spur of schist runs northerly from the 

 pond into Mormon hill, all the ledges adjacent to this shore being the 

 same. The road to H. Scales's house passes over schist nearly to G. 

 Presby's ; then it crosses the serrated boundary between the slates and 

 argillitic conglomerate. There are at least five serratures or projections 

 of the slate over the conglomerate, which may be seen best upon the 

 map. On the hill west of Scales's the schistose conglomerate dips 80° 

 N. 62° W. The slates dip north-westerly, in some cases being inverted. 



The schists have not been followed across the west flank of Mormon 

 hill, but are supposed to be continuous with the ledges seen in the stream 

 east of G. D. Shute's, in the south part of Littleton, dipping 80° N. 42^^ 

 W., and delineated upon Fig. 33. They are here flanked south-easterly 

 by Helderberg flags, and north-westerly by the Lisbon group. They 

 continue north-easterly from Shute's across the township, widening north- 

 erly, and crowding the Lisbon group into Vermont north of Littleton. 

 The next road crossing them is that running directly from the slate 

 quarry to Upper Waterford bridge. The rock is about vertical, and lies 

 between the houses of D. Robbins and A. Eastman — half a mile. Next 

 it crosses the roads from Littleton to this same bridge and to Lancaster. 

 It occupies much of Wheeler hill, and perhaps it should be made to cover 

 all the ground from Palmer hill to the Helderberg on Burnham hill. The 

 dips on this last route are given in the first figure descriptive of the Hel- 

 derberg rocks. On the south side of these hills, west of E. Farr's, green- 

 ish schists occur, dipping 78° N. 40° W. At P. S. Hatch's, north of the 

 limestone, the white rocks dip 40° S. 42° E. On the road between 

 Mann's hill and Mt. Misery this rock dips N. 12° W. and N. 32° W., near 

 J. W. Dudley's. On the north side of the road excavations have been 

 made in this for gold. The rock is completely filled with pyrites, so that 

 small specimens even cannot be obtained free from the sulphuret. Mid- 

 way between the Mt. Misery road and the one along Cow brook, the 

 dip is from 5o°-7o° S. 6° W. Farther west, at M. Fisk's, in perhaps an
