 cases, the eastern range is marked wanting, as both are united into one.

The strata dip east generally in the whole of the belt of limestone in the towns of Cornwall, Whiting, 

 Shoreham, Sudbury, Hubbardton, Benson, and Fairhaven. Local exceptions occur in a few places. 

 Probably most of the strata increase their amount of inclination as we penetrate into the earth. Examples 

 of this sort can be seen in Sheldon & Slason's quarry in West Rutland, where the dip increases as much as 

 10; and north of Middlebury village, where the inclination increases 40 in a few feet of depth. 



There is so much importance attached to this subject, that we give upon Plate VIII, Fig. 2, an enlarged 

 map of the peculiarly disturbed region between Pittsford and Dorset. This figure shows what sort of a 

 geological map is needed for the whole State. Every slight variation in the dip should be noticed, and the 

 dip and strike, also, for every square .half mile, or oftener. Not merely the position of the Eolian limestone, 

 but also of the slate, quartz rock, and conglomerate. And they should be considered topographically. 



It will be observed that the position of the limestone is not uniformly the same. F<3r example, the 

 limestone adjoining the talcpid schists dips west in the south part of Dorset, east in the north part, south- 

 west in the southwest part of Danby, east in the north part of Danby, west through most of Tinmouth, 

 mostly west in Clarendon ; then it is interrupted by a band of slate. Passing by this interruption, from 

 West Rutland to Brandon the dip is uniformly to the east. Similar variations may be noticed along the 

 east border of the Eolian limestone, adjoining the quartz rock. Similar facts appear upon examining the
