dlebury Marble Quarry above-mentioned extends northward 



of New Haven to New Haven River, a distance 



miles. The following figure represents a section 

 the southern border of 



r of Xew Haven town, 

 the town of New Haven. There are in succession, going east- 

 ward along the lines of section, 150 feet of dolomite (a) ; 200 feet 

 of marble (b) ; 150 feet of dolomite (c) ; 10 feet of gray quartsyte 

 (d) ; 800 feet (e) of buff and reddish quartzyte with some slate. 

 The quartzite has been made the overlying rock in the view of 

 Mr. Wing by an overthrow fold. This quartzyte belt, with the 

 limestone west of it, stops at New Haven River. But, 80 to 

 100 rods to the west, another belt begins which stretches north- 

 ward, passing just east of New Haven village (four miles from 

 New Haven River), and finally joins the Red Sandrock of 

 Monkton. 



At a place two and a half miles south of New Haven village, 

 in a field belonging to Mr. J. Brown, a small Orthoemu was 

 found over the weathered surface of the dolomite just west of 

 the quartzyte, which was apparently identical in species with 

 those of the 1 tioned. The Orthoceras is closely 



like tl ..* ,.f Sh,,reham (figured on page 342), which was found 

 in limestone adjoining the underlving sandrock. The quartzyte 

 at Mr. J. Brown's, two and a half miles north of New Haven 

 - 400 to 500 feet thick, dips eastward at an angle of 

 50° to 60° and contains " numerous Fucoids and obscure 

 Scolithi." '
