the superticial zone of rock-decay, and is mainly exliibited in 
the upper workings. This indeed increases with proximity 
to the surface. 
Epidotization of amphibole and pyroxene is likewise a 
characteristic of shallow or superficial portions of the larger 
magnetic lenses of Asche count}^ in the same state. The ore 
developments in that part of the New river basin occupy 
the same relative topographical position with reference to the 
Blue ridge and Stone Mt. as the Cranberry mines. Their 
stratigraphic environment is also similar. The old bloom- 
aries on Helton creek and other waters of New river, like the 
old Cranberry forge, had their ore supply from float ore, and 
iron sands in. sitit, tlie latter from decayed outcrops of epi- 
dotic magnetite lenses, and stratiform augitic material irreg- 
ularly altered into epidote and magnetite, and probably ap- 
pertaining to a single stratigraphical horizon. A number of 
sharp folds present a series of such deposits the parallelism 
of which is due to replication. At numerous localities in the 
New river basin the exhibition of float ore is remarkable^ 
though in point of quality and as indications of important 
deposits in place uncommonly deceptive. The best of this 
material owes its extraordinary purit}^ to secular weathering. 
This is shown by its vesicular condition as a result of disin- 
tegration and elimination of silicates. Float of this descrip- 
tion is especially characteristic of what has been distributed 
by ablation and gravit}' from the smaller or thinner lenses or 
plates. Indeed — according to my own experience in Asche 
county, the exhibition of this enduring kind of ore detritus is 
apt to be the more imposing the less the size or importance of 
the original deposit. 
The Cranberry mine is wrought partly in open quarry and 
partly b}- levels, the separate workings being connected on 
the dip. Parts of six distinct ore lenses are exhibited on the 
face of the quarry one above another and in echelon. These, 
defined in short as differentiations or concentrations of mag- 
netite in the augitic belt, })ass insensibly into non-feriferous 
material. The lowermost of these, the largest of the series, is 
likewise wrought in the underground workings. 
The lower level 330 feet in length enters the ridge directly
