About one mile southeast of Sherburne village is a high hill 

 near the foot of which, about seventy-five feet above the R. R. 

 level or 1 1 1 7 / A. T.,* are somewhat coarse arenaceous shales 

 with a moderate number of fossils, principally of the large 

 species, as Spirifera granulif era^ Hall and its usual associated 

 species. The fauna is distinctively Hamilton and the shales 

 are in the Hamilton stage. Then for a distance of 440 ' the 

 hill slope is covered and at an elevation of 515 r above R. R. 

 level or 1557' A. T., there is an outcrop of coarse arenaceous 

 shales alternating with thin blue flagstones. This bed contains 

 some fossils and the fauna is the same as that of the highest 

 exposures on the hills near Smyrna. The blue argillaceous 

 shale, black shale and limestone below this zone are not shown 

 in this section, on account of the thick deposit of drift. 



About three miles north of Sherburne is the Mulligan 

 quarry, at the top of a high hill, which furnishes thin blue 

 flagstones with coarse irregular shales above them, containing 

 fossils similar to those near the top of the hill west of Smyrna 

 and the one southeast of Sherburne. By the barometer, this 

 exposure is from 424' to 446' above the R. R., or 1466 r to 

 1488' A. T. 



The R. R. station at Sherburne is 1042' A. T.
