FIFTH REPORT OF THE DIRECTOR I908 



a Normal anticline inliers. In 

 this group it will be advanta- 

 geous to distinguish between the 

 long bandlike inliers produced 

 by long typical folds and the 

 short elliptical inliers which re- 

 sult from the short pitching an- 

 ticlines [brachyanticlines Lory, 

 see E.Haug, Traite de Geologi?, 

 1907. p. 204] with periclinal 

 extremities. Examples of the 

 first group are found in the 

 folded region in the eastern part 

 of the State where the long nar- 

 row strips of Lower Cambric, 

 especially north of the Hoosic 

 river, represent, according to the 

 present conception of the struc- 

 ture of this region, more or less 

 complex anticlines. 1 The Cam- 

 bric is here surrounded or 

 thought to protrude from Lower 

 Siluric rocks. This conception is 

 shown in Dale's section of the 

 north end of the Taconic range. 

 It is, however, possible that the 

 relations of the Cambric to the 

 Lower Siluric are greatly dif- 

 ferent in the slate belt and we 

 will recur to this point under 

 the heading of overthrust inliers 

 [sec p. 188] . To find undoubted 

 macroanticlinal inliers we have 

 to go outside of the State, to 

 the northern extension of our 

 folded regions, to Vermont, and 

 to the Allegheny mountains. 

 Here are long belts of Cam- 

 bric rocks inclosed by the Lower 

 Siluric areas and such of the
