the detailed stratigraphy of that region as it has been worked out 

 by the members of the Geological Survey. The map will cover 

 the quadrangles of Canandaigua, Naples, Bath, Phelps, Penn Yan

 of Mormon hill, near Palmyra, celebrated for its historical asso- 

 ciations as the place where the alleged " gold plates " of the Mormon 

 bible were dug up and quite as interesting geologically as an illustra- 

 tion of a glacial drumlin, a topographic form which occurs abund- 

 antly in the region of the Lake Ontario plain.
