GEOLOGY OF THE CONNECTICUT VALLEY DISTRICT. 309 



certainly an accumulation by shoving of an unusually large mass on this 

 hillside. In favor of a synclinal structure we have the apparent starting 

 out of two conglomerate lines from the Dow ledge, spreading out 2000 

 feet before reaching the south town line, and uniting again in the north- 

 ern part of Bath. To the east of the Dow ledge, 400 feet, there is 

 another fragment whose northern end touches the hill in the same way 

 with the last, and capped by dolomite. The fragment is 800 feet long, 

 at first N. 35° E., and then with a more nearly north-south course. It 

 nearly reaches the road from Lisbon village over the hill to Smith brook. 

 A hill between this road and R. D. Moulton's house on the Bath line has 

 the same general course, and appears to be underlaid by conglomerates, 

 800 feet long. On the opposite side of the valley there is a ledge of the 

 conglomerate running 1000 feet S. 35° W. up the hill before reaching the 

 Bath line. A line of boulders running easterly from the north end of 

 this last named fragment, between B — 17 and 18, is suggestive of a bend 

 towards the Dow ledge. This ledge on the west side of the valley rises 

 to the top of the hill, and then passes by the house of H, Ash in Bath, 

 and continues uninterruptedly nearly to the brick house occupied by M. 

 L. Sanborn in Bath, a distance of one mile and seven eighths in a right 

 line. I have protracted carefully upon the map, measured with chain and 

 compass, the various bends of this formation in Bath, and will not par- 

 ticularize the details here. There are about thirty angles made in its 

 course, which might be mentioned in detail. There is frequently a high 

 wall upon the western side, as in the south part of Lyman. Dolomite 

 beds cling to it continuously on the west side. At the lower end the 

 course reminds one of escalloped embroidery. Concerning the relation 

 of the slates, Lyman schist, and conglomerate at this lower end, sufficient 

 mention has already been made (page 293). 



While the western side of the basin, if it may be so called, is continu- 

 ous, the eastern has been badly shattered. Near the town line there is 

 a fragment a third of a mile long, roughly parallel to the western belt, 

 about the same distance apart as before, above R. D. Moulton's. Farther 

 south we find only remnants, five pieces scattered for half a mile, begin- 

 ning five sixths of a mile south of the town line, and terminating fifty 

 rods east of the western belt, where it bends sharply to the east for about 

 forty rods. No other fragments occur save for the last half mile before
