294 STRATIGRAPHICAL GEOLOGY. 



Many of the details of its distribution and stratigraphical relations have 

 been touched upon in the descriptions of Figs. 29-33, Plate XIII. 



By reference to the map exhibiting the south end of the auriferous 

 conglomerate in Bath, it appears that the Lyman schists are enclosed by 

 it, and the conglomerate is encompassed by clay slate, while the slates 

 apparently dip beneath the other rocks. This does not represent the 

 true mutual relations of these formations, as the slates overlie the others. 

 A careful examination of the dips from the south end of the conglomer- 

 ate to the neighborhood of the house of J. Clough (county map), proves 

 the existence of singular disturbances, both dislocations and overturns. 

 The normal dip of the slate upon the east side of the conglomerate in 

 Bath is 30°-40° N. 42° W. The strike is the same upon the west side 

 and to the south ; but the dip varies, as will be described further along, 

 in accordance with the synclinal disposition of the mass. In the road a 

 little west of the brick house (M. L. Sanborn, of county map), the dip is 

 to the north. Quite near to the conglomerate, upon the west side, the 

 dip is N. 33° E., and N. 18° E. The slate and conglomerate are sepa- 

 rated by a few feet thickness of the argillitic mica schist and the common 

 shelly layers of the Lyman group. Three hundred feet west of the con- 

 glomerate the slate dips N. 72° W., or more nearly its proper position. 

 The usual presence of the few layers of Lyman rocks with the conglom- 

 erate, not merely here, but very commonly where the conglomerate lies 

 in close proximity to the slate, indicates the proper associations of the 

 former rock, and that the latter has been crowded over it by lateral 

 pressure. 



Near the south end of the conglomerate upon the hill there is another 

 illustration of this conclusion. Two masses of conglomerate run parallel 

 to each other a few rods apart, both uniformly having a strike a little east 

 of north. Between them lies an abundance of the slate, with the uniform 

 north-westerly dip belonging to it, thus unconformably overlying the con- 

 glomerate. 



The action of the lateral pressure is further exhibited a few rods north- 

 easterly from Clough's house. A hummock of the Lyman dolomitic 

 and quartzose rocks rises out of the slate; or, perhaps it should be said, 

 rather, the rocks associated with the conglomerate extend westward more 

 than is usual, and consequently the slate has been displaced. A portion
