remarkably fine deep-blue gem from Eoyalston, Massachusetts, weighing
over 10 carats, is in the United States National Museum, and in the

Upper Providence, and in Middletown, Concord, and Marple townships,

White Horse, 3 or 4 miles below Darby, Pennsylvania. Bluish green and
blue beryls occur in the vicinity of Unionville, Newlin township, and
