= Shelburne marble Clouded grey soft marble, that all dips east at about 25 degrees. The manager told me it runs between 90 and 96 percent carbonate of lime, about 3-1/4% free magnesium carbonate. One bed about 3 feet thick was picked in sand with the grains all rounded ad large, a coarsest grain 1/16 not in diameter. Keith says it rules Milton for the actual contact below out-crop. It's not likely the hill- top which is Bellmantown, from sounding of the Shelburne is not the same marble that constitutes the lower part of the Bellmantown seen at Phillips- hury. Saw no fossils, but the Manager said Phillips had gotten some. He also said there is a ridge group of dolomites. I saw some dull fractured grains. And that there were the Shelburne for certain that none of it occurs in the Trenton carbonate. Probably all of these "Shelburne" Hicks are lenticles only of the Caledonian. Stopping at the Remount Hotel.
