	usually colorless, light pink, light blue, bluish pink, light golden, and sections show the characteristic variety of color, such as blue and pink, green and pink, when viewed through the end of the crystal. Some of the faintly-colored crystals afforded gems that were considerably darker after the cutting. During the last summer the north side of this locality has been worked by Mr. G. C. Hatch and Mr. T. F. Lamb, and much darker material has been found, especially the green colors, some of which equal anything found at Mount Mica. Rude black crystals were observed here 8 inches in diameter and 12 feet long, and at times inclosing quartzite. Several specimens were almost emerald color, and would afford gems. This promises well to afford fine gems for some time to come, as well as the Mount Mica locality. Mr. Lucien Holmes, of Standish, Maine, found crystals of green, red, and blue tourmaline on the Hussey farm, but they were not of gem quality, although very good as crystals. As little work has been done, this locality might improve by development. The specimens at Bates College, Lewiston, labelled "Baldwin," are supposed to have been found at this locality. During the last year Mr. E. G. Bailey and Dr. A. C. Hamlin have opened the Mount Black locality at Rumford and Andover, Maine. The indications here are quite good for gems, and a quantity of rubellite, a great quantity of lepidolite, spodumene 3 feet long, cookite, ambly-gonite, and other minerals similar to those of the Mount Mica, were taken out, none however of gem quality. The tourmaline mentioned in Hamlin's " Tourmaline," page 72, was found about 1860, by Augustus Lane, at Welcome's Corner, on the Boutelle farm. This specimen was first recognized by Dr. Hoar. The locality is about half a mile from the Hatch farm, and the indications were found by Dr. Hamlin on working, in 1860 and 1862, to be the same as at the Hatch farm. The localities in Maine that have furnished fine tourmalines are Mount Mica at Paris, two localities at Auburn, Hebron, Norway, Mount Black in Andover and Rumford, as well as the Standish locality; the two latter have furnished no gems. Some of the finest of the cut rubellites and green tourmalines are in the possession of Prof. C. U. Shepard and members of his family. One of the most magnificent known green tourmalines is one, the color of which is described by Professor Shepard as of a chrysolite-green, and having a blue tinge, while less yellow and more green than chrysolite. It is 1 inch long, § inch broad, and 1 inch thick, and finer than any of the Hope gems. One fine rubellite of two-thirds this size, and equally tine, one pink topaz one half this size, and one remarkable rubellite the size of the large green tourmaline, are also in possession of this family. The Hamlin cabinet (a), the first crystal of which was found in 1820, a See "The Tourmaline," by A. C. Hamlin,
