prospecting
has been done for them and accordingly only surface specimens have been
found. The fields have light sandy soil with scattered blocks of
hornblende gneiss through it, such as might be derived from the
disintegration of granite with hornblende gneiss inclusions.
Amethyst
is also reported on the place of J. T. Algary, about 4 miles south of
east of Donalds. A good specimen consisting of a cluster of clear pale
amethyst crystals from the Algary place was seas at the home of T. F.
Drake, of Shoals Junction. This cluster meas-ured 8 inches across and 3
inches thick, and contained some crystals 2 inches thick.
BERYL.
NEW ENGLAND.
Beryl
suitable for specimens and gems have been found at many localities in
New England. Some of these have been mined for that mineral alone and
others have been worked for feldspar and the has been saved as a
valuable accessory mineral. In Connecticut fine golden beryl has been
obtained from near New Milford, Litchfield County, and during 1913 good
aquamarine was found near East Hampton, in Middlesex County. In Maine
beryl is widespread in the
E
egmatites worked for
feldspar. Several localities have yielded gem eryl, and among these are
prospects in the towns of Buckfield and Stoneham. In Massachusetts
Goshen and Royalston have afforded beautiful gem beryl. In New
Hampshire beryl is abundant in many of the mica-bearing pegmatites, and
some of these have yielded good gems.
A
brief examination of several of the New England beryl localities was
made in June, 1913. Unfortunately time for this work was so limited
that none of the Connecticut localities were visited.
MAINE.
Exceptionally
fine beryl gems have been found in the town of Stoneham, Me., at
scattered localities. Some of these were visited, but very little local
interest was shown in the possibilities of these deposits at that time
and only outcrops and old prospects were available for examination. The
writer was fortunate in having Mr. Wesley Adams, of North Lovell, guide
him to some of the many prospects with which he is familiar. Among
these were Sugar Hill. Durgin Mountain, and Chapman Hill or Thousand
Acre Hill.
Sugar
Hill is about 3 miles northwest of North Lovell. Beryl and associated
minerals have been found at several places on the south side of the
hill on the land of Edwin McAllister. At one place a prospect pit had
been opened in loose talus or drift material a few yards below a rather
flat-lying cliff-forming ledge of pegmatite. In this loose drift were
found fragments and crystals of beryllonite, a phosphate of beryllium
and sodium, beryl, smoky, clear, and transparent gray quartz, mica,
and potash feldspar. E. S. Bastin' mentions also apatite, cassiteiite,
columbite, and triplite as having been found here. The pegmatite ledge
outcrops about 40 feet higher up on the hillside and, at a distance of
about 150 feet northeast of
