allow
the cutting of even a small gem. The beryls from Monroe, Conn., often
present interrupted curvatures as shown in Fig. 2. During the last
twenty years many beryls, approaching those from New Hampshire in
magnitude, have been found in other localites, chiefly in Oxford
County, Me., in North Carolina, and in Amelia County, Va., all of which
have furnished crystals from 2 to 4 feet in length and 1 foot or more
in diameter. Only occasionally small spaces are clear enough to afford
gems. Mr. Stephenson called the attention of the writer to a crystal of
dark-green beryl, weighing 254 ounces, part of which would furnish gems
of some size, that was found in January, 1888, near Russell Gap Road,
Alexander County, N. C, by a farmer plowing. This locality is about ten
miles from the Alexander County Emerald Mine, and is the largest beryl
deposit affording gems that has been found in North Carolina. It is
noteworthy that the highly modified beryls of this region occur rarely,
and only when associated with spodumene or albite, and also that the
white or pale-greenish beryls are found with the deepest green
spodumene. It has before been noted that the quartz and beryl of
Alexander County are more highly modified when implanted on the
feldspathic layers of the walls of the pockets. Two emerald beryls,
which were found in 1881, at a depth of 34 feet, were in a little
pocket, the walls of which were almost covered with crystals of albite
twinned parallel to the base. Only four emeralds were found, averaging
about 1 centimeter in the three dimensions. The pocket was free from
all decomposition whatÂever. The crystals were of good color,
transparent, and had their commoner planes well polished, but they
differed to some extent in habit.1 Blue beryl in fine
crystals that afforded fair gems was reported by William E. Hidden from
Mitchell County, near the Yancey County line, N. C. In the State
cabinet in Albany, N. Y., is a curious beryl found by S. C. Hatch at
Auburn, Me. It is of imperfect structure and broken diagonally across,
showing the structure to advantage. (See Fig. 2.) It is 8 1/2 inches, 30 centimeters high, 8 3/5 inches, 22
