7. Leap. 
A few small irregular lumps of what has been 'alleged to be “native 
lead,” were received fiom Messrs. Beehtler, of Morganton. They were 
said to have been dug up four miles north of Morganton, in making a 
road near the Catawba river. 
8. Antimony. 
A small piece of native antimony was received, from Dr. Hunter. It 
is quite pure and free from arsenic, but coated with a crust of antimonic 
oxide. From a small vein in Burke county. 
9. Sulphur. 
It is frequently met with in minute crystals in cellular quartz, filling 
the cavities formerly occupied by pyrite, in Cabarrus, Mecklenburg, Gas 
ton, Caldwell and Stokes counties; k also occurs diffused through the 
interstices of a white quartzose sandrock in Lincoln county. 
10. Diamond. 
This rare gem has been repeatedly found in North Carolina, and the 
following occurrences have been well established. In every instance it 
was found associated with gold and zircons, sometimes with monazite ard 
other rare minerals in gravelbeds, resulting from gneissoid rocks, but it 
has never been observed in the North Carolina itacolumite or any debris 
resulting from its disintegration. The first diamond was found in 1813 
by Dr. M. F Stephenson, of Gainesville, Georgia, at the ford of Brindle- 
town creek. It was an octahedron, valued at about one hundred dollars. 
Another from the same neighborhood came into possession of Prof, 
Featherstonehough, while acting as United States Geologist. 
The third diamond, at Twitty’s Mine, Rutherford county, was observed 
in 1846, by General Clingman in D. J. Twitty’s collection, and has been 
described by Prof. Shepard. Its form is a distorted hexoctahedron, and 
its color yellowish. 
The fourth came fiom near Cottage Home, in Lincoln county, where it 
was discovered in the spring of 1852, and was recognized by Dr. C. L. 
Hunter. It is greenish and in form similar to the last, but more elongated. 
A very beautiful diamond was found in the summer of 1S52 in Todd’s 
branch, Mecklenburg county. It was nearly of the first water and a per-
