ounces of common pieces of the same mineral. The company estimates the
value of this entire yield of hiddenite at about $2,500.

There was also found a quantity of quartz filled with white byssolite,
forming very attractive specimens and valued at $250.

A number of beryls of a fine blue color, resembling the Mourne Mountain
specimens, were found near Mount Antero, Chaffee County, Col. One of these
was 4 inches long and 3/8 of an inch across, with cutting material in it.
The other crystals measured from 1 to 1¼ inch in length, and from 1/5 to
1/3 inch in width.

The large beryl mentioned by Mr. Kunz in the Mineral Resources for 1883 and

light blue color, from white beryls found in the company's mica mine at
North Grafton, N.H.

A number of fine, deep golden-yellow, blue, and green beryls, equaling any
ever found, have been taken by Mr. M.W. Barse from his mica mine between
New Milford and Litchfield, Conn. Some fine blood-red garnets from this
