    in a high hill or mountain, as in Missouri, but is on the same level with the cultivated fields adjoining, occupying a superficial area of the imme- diate surface of about eight acres; the ground over this area being exclusively covered with fragments and blocks of magnetic iron ore occasionally mixed with loadstone. Beneath the surface it extends to an unknown depth. It has been penetrated from four to five feet with- out finding any change of the material, except that the loadstones seem to be more abundant on the surface. [The loadstones are now quite scarce, and the Professor was mis- taken in regard to the iron ore extending to any great depth. Dr. G. W. Lawrence, who now owns part of the Mitchell farm, says it is con- fined to within a few feet of the surface. The writer examined several places and could find none three to five feet below the surface; but it does exist in other parts of the Cove and on the hills surrounding it, and in quantities sufficiently large to justify the erection of furnaces as soon as the railroad furnishes transportation. On the farm of Dr. Holiman a large bed of bog iron was seen. This ore is easily worked and contains 35 to 40 per cent, of iron.] An analysis has been made of'the magnetic iron ore with the fol- lowing results: Insoluble matter 3.20 Moisture Peroxide of iron 67.20 Protoxide of iron 24.46 Manganese * * 3° Titanic acid I-2° Alumina 45 Lime, magnesia, and loss .- 2.19 100.00 The lapping of the arable land on the margin of the magnetic iron ore conceals its relation to the adjacent rocks; but from the minerals. • ploughed up in the fields on the south and southeast the magnetic iron ore seems to be surrounded, in part at least, with mica slates. Along with the large flakes of this mineral, brought to the surface by the plow, are beautiful crystals of augite and black garnets. Adjoining the flucan of mica is a schorlamite granite. On the west part of section 19, where this rock is exposed in the bed of Cove Creek, some galena is reported to have been found; but none of any consequence was discovered when I examined the 1 Cove.'
