tween Lily pond and a small church this rock occurs, and has 

 interstratified with it a few layers of conglomerate, some of whose 

 constituent pebbles have been flattened and elongated in the direc- 

 tion of the strike. They dip 45° N. 10° E. That part of this rock 

 which is situated nearest the river, in the central portions of the 

 village, merges into a greenish schist, having a small easterly dip ; 

 while the more northern portions, as on the road to Camden, are 

 dark silicious slates and black slaty quartz rock, dipping 45° N. 

 40° E. West of the bridge in Rockport the dip of this slaty quartz 

 is northerly. 



Two islands off Beauchamp's point are represented npon our 

 map in Fig. 36, the lowest one, Lowell's rock, being entirely 

 composed of quartz rock ; and the other, Indian island, having a 

 micaceous schist with the quartz. 



Concerning the belt of quartz rock in Rockland which lies be- 

 tween two belts of limestone but little need be said. A reference 

 to the map will show its situation, and Fig. 39 will show its strati- 

 graphical relations. It appears to constitute an anticlinal axis, 

 underlying both bands of limestone. This rock constitutes the 

 foundation of the highest hill north-west from Rockland, or where 

 the Fourth Regiment M. Y. M. was encamped last summer. 



Mount Battle is an immense pile of consolidated distorted peb- 

 bles, and beiongs to this formation, since the rock is pure silica, 

 and seems to be of the same age. Last year we said something 

 about this mountain under the erroneous name of Megunticook 

 mountain. The latter name belongs to the granitic pile behind 

 Battle, of still grander proportions. Mount Battle is exceedingly 

 precipitous — it being impossible to ascend it on the east and south 

 sides. The strata are very obscure, although at almost every step 

 the pebbles composing them are obvious. Upon the south and east 

 •sides of the mountain the strata appear to dip southerly and east- 

 erly at a small angle, and they are thus represented in the section, 

 Fig. 41. Professor Emmons estimates the dip at 25° S. E. 



Those who are interested in the exhibition of distorted pebbles 

 in conglomerate may find examples upon Mount Battle. We 

 would not represent this case as a typical one ; i. e., one where the 

 phenomena are in the greatest perfection. Still the proximity of 

 this locality to frequented routes of travel makes it a good one to 

 visit. The finest examples of these distortions occur in the less 

 frequented parts of the State, as in Rangely. These pebbles on
