This table of inclinations most clearly points out the fact that the almost invariable dip of the strata is 

 to the east. There are only two exceptions, and these are of a local character. There are two spurs pro- 

 jecting from the terrain ; one to the north at St. Albans ; the other to the south, terminating at Milton 

 Falls. If we are to regard any of these dips as inverted, these projections may furnish the materials out of 

 which we may construct a single plication. We prefer not to conjecture the number, position or order of 

 any inverted axes in the talcose conglomerates ; hoping that after geologists agree respecting the age of the 

 Georgia slate, some light may be thrown upon this group of rocks, which is superimposed stratigraphically 

 upon the Georgia slate. 



Range, Extent and Thickness. 



The talcose conglomerates form one simple deposit, extending perhaps from Walling- 

 ford, certainly from Lincoln, to the northern line of the State. Some of the deposits of 

 quartz rock, talcose schist, and conglomerate in Pittsford and Chittenden, undoubtedly 

 are of the same age as this group, but we are unable at present to separate them from 

 the quartz rock. We think that the talcose grits and mica schists, upon Sections VII. 

 and VIII, in Brandon, Goshen, and Ripton, belong to this group. A good section crosses 

 this group of rocks in Lincoln. See Fig. 248. The following is the order of rocks there, 

 beginning at the bottom : Quartzite, talcose schist, talcose sandstones, talcose schists, 

 talcose sandstones, talcose schists, talcose grits, conglomerates, talcose sandstones, talcose 

 schists and grits. In the north part of Starksboro, the rock at the west border of this 

 talcose belt is a dark colored grit, standing upon its edges, and running N. 10 E. In the 

 south part of Hinesburgh no rocks were observed in crossing the formation, except talcose
