in bluish-grey to buff sandstones was opened by Mr. Burns, but the stone did 

 not prove valuable. 



XLI L 2 . Still higher than the Burns quarry is one that was opened 

 during the construction of the railroad and furnished stone for the abutments 

 of the bridge. At the bottom of the railroad quarry are grey sandstones, 

 then red sandstones that are capped by red shale. The red rocks are about 

 thirty feet below the railroad track, or 1,167 feet A. T. If these reds corre- 

 spond to the lowest reds in the hill west of Norwich, and they seem to have 

 that position, then they will give the dip along almost a direct north and 

 south line. The red shales west of Norwich are 1,476 feet A. T., and the 

 distance between the two places four and eight-tenths miles, giving us a dip 

 to the south of 64 + feet per mile. 



To the south of the bridge there are railroad cuts through coarse-grained, 

 greenish-grey sandstones, alternating with red shales, which show clearly 

 enough that these rocks are in the Oneonta formation. In these shales 

 specimens of a fern — Archceopteris sp. — were found. Farther south, near the 

 middle of a cut through the coarse grey sandstone, just north of the 218th 

 New York mile post, are numerous fragments of plants, among which is 

 Lepidodendron, Craspicmum, I)n. In the same cut, specimens of the character, 

 istic .fossil of the Oneonta sandstone, Amnigenia CatskiUmsis (V an.), Hall, 

 occur, and an unusually good specimen of Holonema rugosa (Claypole), Newb., 

 was found. This specimen of a fossil fish has been described by Professors 

 H. S. Williams, 1 Claypole 2 and Cope, 3 while the last edition of Dana's Manual 

 of Geology contains a figure showing the restored ventral plates of the 

 species. 4 In addition to the above species, Leptodesma Mogersi, Hall, was 

 (■ported, probably from this cut. 5 



XLI C n . A railroad cut on the New York, Ontario and Western railroad, 

 about two and one-half miles southeast of the Oxford station and one-quarter 

 of a mile north of the 214th New York mile post. The cut is through red 

 and greenish shales, alternating with thin grey sandstones. The dip is at least 

 sixty feet to the mile, twenty degrees west of south. A layer of the nature 

 of a conglomerate, containing an occasional quartz pebble, was noticed. 

 Fucoidal markings occur in the grey sandstones, while in thin layers quite 

 a number of fossil shells are preserved. The following species from this cut 

 are listed in the Fifth Annual Report of the New York State Geologist:
