diverge somewhat, the width of outcrop widens northward. In this zone 

 meagre exposures are not infrequent, but d<> not suffice for the construction 

 of a section. It seems, however, that only the lower division of the formation 

 is represented. The rock is mainly a hard, massive, grey or iron-grey dolo- 

 mite, but is often very sandy, and in some layers the sand predominates, and 

 the color is lighter. The sand is mainly coarse, and often gives a pseudo- 

 oolitic appearance to the rock. One mile and a half west of Rouse's Point, a 



layer of coarse breccia is exposed, the ordinary grey dolomite containing 

 numerous, rather angular pieces of finer grained, more sandy dolomite, of 

 varying size up to four or five inches in length. These pebbles, if they may 

 be so called, are clearly derived from the formation itself, being precisely like 

 layers w hich occur just beneath the breccia at that point. 



Chazy limestone. A portion of the Chazy is well exposed in the district 

 from Cooperville eastward to King's bay. Nearly the entire Madurm divi- 

 sion and much of the lower division are well shown and very fossil if erous.
