IMMENSE IRON DEPOSITS.
" The examination of shafts to a depth of fifty feet, chisel
and drill marks, and other unmistakable evidences, leave
no doubt that the Spaniards formerly worked these mines,
and remains of the ore worked, show it to have been very
"IRoN.-The iron deposits of Northwestern Texas are of
the most remarkable character, equalling in extent and
richness those of Sweden, Missouri, New Jersey and New
York. They include almost every variety-magnetic,
spathic, specular and hematite ores. Thelargest deposits
of magnetic iron ores occur in Mason, Llano and more
Western counties. Immense loose masses of ore lie
scattered over the surface, which have been upheaved by
ingenious agencies from unknown depths below. Mostof
these are in true veins. As no true metallic vein has ever
been traced downward to its termination, the supply is
inexhaustible. The analysis of an average specimen gave
96.890 per cent. of per-oxide of iron, with 2.818 per cent.
of isoluble silicious substances-proving it to be a magnetic
oxide, which will yield 74.93 pounds of metallic iron
to 100 pounds of ore.
"The prevailing rocks are red feldspathic granite, gneiss,
quartz, talcose and chloritic shists. Granite ridge surrounds
the deposits, and veins of quartz traverse it in all
directions, The limestone of the palezoic and cretaceous
rocks are in the immediate vicinity, from which materials
for flux can be easily obtained. A most remarkable development
of hematite and limonite occurs on the waters
of Red River. It is found in regular layers of from fifty
to sixty feet in thickness. Associated with these ores are
various oxides of iron, suitable for pigments of red,
yellow and brown colors distributed, forming regular
layers of several feet in thickness. The largest amount
is on vacant lands-subject to location by certificates.
