Comments on the commodity information

  • TOPO SHOWS TWO SMALL PONDS AND ONE LARGE POND, THE NORTHERN PART OF WHICH IS THE PALMER PIT OF THE AMENIA MINE, AND THE SMALLER SOUTHERN PART IS THE GRIDLEY MINE PIT (HARTFORD SHEET, NO. 54). THE PALMER PIT IS 700 FT. LONG NORTH-SOUTH, 200 FT. WIDE EAST-WEST, AND 115 FT. DEEP. OF THE TWO SMALL PONDS ARE THE WEED MINE WORKINGS. EACH PIT IS ABOUT 400 FT. LONG NORTH-SOUTH, 150 FT. WIDE EAST-WEST, AND ABOUT 20 FT. DEEP.
