were not removed, so that there is now a valley along the anticli- 

 nal ridge. This is what is called an anticlinal valley. Between 

 Chickawakie pond and Clam cove there is a synclinal axis. It is 

 remarkable that a northerly dip should be the prevailing one north 

 of this pond, extending even into the mica schist of the older for- 

 mation. At the north-west side of the pond is a north-westerly 

 dip which is connected with the inverted anticlinal at- Holmes' 

 quarry further south. There is no axis in the Camden deposit ; 

 although there is some diversity of dip, it is very difficult to find 

 anything more than local folds, of which the one in Camden village 

 is a sample. The variations generally are all contained in a single 

 quadrant. The small south-westerly dip on the west side of Mt. 

 Battle is probably an isolated remnant of the original position of the 

 belt. The Camden schists are all in one belt, then, dipping north- 

 erly and north-easterly, but making a great bend like the Eolian 

 limestone and quartz rock beneath. 



In the Belfast belt we get a few axes. At Appleton none were 

 observed, but in the vicinity of Belfast we have two : a synclinal 

 west of Belfast city, which we have traced ten miles into Belmont ; 

 and an anticlinal still further west in Waldo. An anticlinal exists 

 in the north-east part of Stockton in similar rocks, and most proba- 

 bly the very same belt. 



The schists on Owl's Head promontory are largely quartzose. 

 Indeed, at the end of the point the rock is entirely quartz. The 

 western portion contains a great deal of mica and presents a woe- 

 begone appearance. The quartz contains tubercular veins of a 

 whiter and purer hyaline quartz. A few veins of syenite are also 

 present. The greater portion of the schists in Thomaston and 

 Rockland are v'ery handsome readily cleaving layers of a pretty well 

 characterized mica schist, generally too much penetrated by jointed 

 planes to allow very large plates to be exhumed from the ledges. 

 At the east end of Thomaston village, on the west bank of Mill 

 river, and lying exposed very prominently in the street, is a large 

 ledge of a very argillaceous schist, much like the characteristic 

 Taconic schists in Massachusetts and Vermont. It is seen again 

 in the bed of the river lower down. The rock in Mr. Jacob's 

 garden is similar, and it crops out again at the Toll Bridge to 

 Cushing. On the west side of the bridge the rock is largely quart- 

 zose, and may be in the same layer with the ledge of quartz on the 

 road to the Beachwoods quarry, seen after leaving the main street.
