associated
with a quantity of some of the finest chipped arrow points of
chalcedony anywhere found, and yet no trace of a chipped crystal could
be found among them. In a number of the mounds leveled by the farmers
in cultivating, and not worked systematically, many single crystals of
quartz were revealed, which may, however, have been kept for their
beauty and symmetry by the Indians. These masses of transparent
quartz, especially from North Carolina, would afford perfectly clear
crystal balls, at least 2 to 4 inches in diameter, and a few have been
cut over 2 inches.
A
large mass weighing 5 kilos was recently brought from Alaska, and was
only a part of an original mass which must have weighed 20 kilos. It
afforded clear crystal slabs for hand glasses 3 by 5 inches. The
superiority of this material over glass lies in the fact that it does
not, like glass, by its color detract from the rosiness of the
countenance. A fine glass of this kind is in the Dresden " green
vaults."
Amethyst.—One
of the finest American amethysts was lately shown me by Mr. L. M. Ives,
of New York City. The color was nearly equal to the finest Siberian,
and the crystal would afford a gem three-eighths inch arcoss. It was
found by Mr. Ives, 1-1/2 miles from Roaring brook, near Cheshire,
Connecticut.
Amethyst
of a light purple and at times pink color is found in crystals 3
inches long and over in large abundance at Clayton, Eabun county,
Georgia. At times these have large liquid cavities containing movable
bubbles of gas. They are of little gem value, although fine as
specimens. Some fine amethysts in the Hamlin cabinet are from Oxford
county, Maine. Very fair crystals were formerly found at Mount
Crawford, Surray, Waterville, and Westmoreland, New Hampshire. Some
very fair crystals have been observed at Bristol, Rhode Island. Dr. F.
A. Genth(a) mentions magnificent specimens from Delaware and Chester
counties, Pennsylvania. Among the principal localities may be mentioned
the farms of S. Entrikin, William Gibbon, Mrs. Faulkes, and Dr.
Elwayne, in East Bradford township; in Pocopson township, John
Entrikin's and Joseph B. Darlington's; Birmingham township, on Davis B.
Williams's farm; in Charlestown township about 1 quart of loose
crystals were obtained; on Charles Passmore's farm, Newlin township,
about 100 pounds have been found. Mr. W. W. Jefferis(b) announced that
amethysts of a rich purple eolor had been found in the northern part of
Newlin township. Splendid crystals, one weighing 7 pounds, though not
gem material, were found at Morgan Hunter's farm in Upper Providence.
Other localities are Astor, Concord, Marple, and Middletown townships.
Near Twaddle's paper mill, in Birmingham, they are found in clusters,
and in isolated crystals near Dutton's mill;
