about 30 inches apart. The Canajoharie chalk chale (forming the Otica) comes in sharply above the Trenton, Here again the top of the Trenton like the Beedman Town has the top somewhat eroded and there are inch of the blue shale in one lying and has parts of Trenton of limestone up to eight inches across and chalk shale forbles. Then all in dull blue somewhat tiny shales = the Canajoharie. The finds cited by Ruedemann (Nus Bull 162, 1912; 30-26) show that the li. and shales belong to one successive series. Even though there may be a heal between them it seems to have no time (stratigic) value. The same graptilites occur in the shales of the limestone that are found in the Canajoharie. Some of the limestone finds persist into Canajoharie shales but as a rule most chief not. The Beedman Town in now divides into the upper Tribs Hill, the Brailifam - facoidel dregs, and the lower Little Falls. The greater thickness is about
