SCIENTIFIC SURVEY. 



255 



from 35° to 80°, and essentially in the same direction. With the 

 names of the different quarries we are unacquainted. 



More exposures of limestone appear on the roads west of Rock- 

 port, some of which are quarried. We find the conglomerate west 

 of the village dipping 60° N. 10° E. ; and north-west of the village, 

 on the west road to Camden, there are quarries. The layers ap- 

 pear to be vertical, with the strike of N. 65° W. Some slaty lay- 

 ers adjacent dip 60° N". Y0° E. At the quarries still further west, 

 near Simonton's Corners, the dip is V0° N. 10° E. Eeyond these, 

 which are very extensively worked, we measured strata dipping 

 15° N. 60° E., and N. 15° E. The rock has been traced to within 

 a short distance of Hosmer pond. As the strata are thrown about 

 in large masses near Hosmer pond, we conclude that the limestone 

 terminates here, because of a dislocation, rather than on account 

 of the gradual thinning out of the strata. 



We introduce here a table of the dips of the Eolian limestone 

 in all the localities where they have been observed, whether already- 

 noticed or flot :
