These specimens were collected near Webster, Jackson 
Co., by Mr, Geo. P. Merrill of the U. S.. National Mu- 
seum. 
On the road from Webster, following up the Tucka- 
seegee river valley and about one half mile from the 
town, a mass of dunitet is exposed for over 1500 feet on 
a hillside facing the river. In the midst of this outcrop, 
the websterite occupies 1 width of nearly 300 feet. This 
outcrop of dunite is very similar to that near Bakersville 
and at Coumdum HiJl, described above. 
This rock as described by Williams,* is composed en- 
tirely of bronzite and an emerald-green diopside, The 
ground mass of this rock is composed of the brilliant 
ereen grains of the diopside through which rounded crys- 
tals of the pale brown bronzite are disseminated. The 
relative amount of the bronzite is variable as it shows a 
tendency to concentrate in nests or bands. 
Lewis** speaks of this rock as a compact granular 
rock closely resembling the dunite with which it is asso- 
ciated, 
Near the north end of the dunite outcrop, at the side 
of the road, boulders were observed, which when broken 
open were found to be composed almost entirely of bron- 
zite. Besides the boulders a mass of the same rock was 
observed apparently @ sz¢z. 
The bronzite composing this rock is of a resinous brown 
color, and of a bronze like luster, even on the unaltered 
surfaces. On the cleavage surface tie Juster is decidely 
pearly. No distinct crystals were observed, the speci- 
mens being a mass of interlocking crystals making a very 
tough rock similiar to the enstatite described above. In 
most of the specimens, the crystals were so interlocked 
that no crystal outline of these could be distinguished. 
In a few of the specimens the crystals were much larger
