The fluorite is white and has disseminated magnetite. It is near the lower workings of the Lovers pit. When this pit was in active operation it en- countered a peculiar, dense, green rock in small amount which, the microscope showed, consisted of quartz and actinolite. It con- tained scattered masses of fluorite of pink and green colors and up to 2 inches in diameter. The most interesting fluorite of all, was however by chance obtained in one of the quarries in the Grenville limestone just north of Port Henry. A rather insignificant crust of dull yellow- ish color, proved to be this mineral, filled with the wormlike growths, technically called " ; The commonest hel- minths are chlorite in quartz, but of what those in the fluorite consist is not Helminths of some unknown mineral in fluorite. Actual field abDut .05 inch Garnet occurs in the North and South pits on Barton hill in excellent rhombic dodecahedra which are at times distorted so as to be greatly flattened. Aside from this occurrence well crystal- lized garnets have not been observed, but massive specimens of the mineral are not uncommon in both anorthosites and basic.
