The Great Mineral Wealth of the State a.
Shown by the Geological Survey.
DR.. Charles R. Keyes. director of the
Missouri geological survey, has recent
ly issued from the office of the bureau
of geology and mines an exhaustive
report on the lead and zinc resources
of Missouri, by Messrs. a. Winslow
and j. D. Robertson. The work is in
two large volumes, aggregating some
500 pages, and is amply illustrated.
From it is learned that the metals
lead and zinc form Missouri's mos t
prominent mineral products. The real
Importance of these metals is further
comprehended when it is known that
as producer of the frst-named ore
the state ranks second among the
states of the Union. and of the second
metal first, supplying more than two
fifths of the entire amount of mineral
in the United States. The report has
been divided into three parts. The
first portion contains an historical
sketch of the metals, and a summary
of what is known of them in all coun-
tries of the globe. Particular atten-
ton is given to the lead and zinc pro-
ducing districts of North America,
with which the Missouri product is
brought into competition. A chapter
is also devoted to the metallurgy of
the metals, and the various processes
are described with sufficient minute
ness for all practical purposes. Con-
else tables of the production of the
United States are also given in this
connection. together with the prices.
The second Saofi0r, orf1ircc he hic.
tory of mining in Missouri, and the
general geology of the southern half
of the state. The development of the
mining in the state is traced from the
time of the earliest explorations. The
physical characters of the lead and
zinc regions are described at length.
The geological formations containing
the metals under consideration are re-
ferred to in general way. and consid-
cradle detail entered into in the case
of the most important localities. The
Theological differences are compared,
and some of the salient structural fea-
lures pointed out. Under ore deposits
is full consideration of the distribu-
ton. the form. structure and compost
ton OF the ore bodies, their manner of
formation and the origin of metallifer-
Gus veins. Concerning the latter topic,
the various theories are set forth and
their application to Missouri deposits
clearly given. Smelling and manu-
featuring received the attention they
demand, and full statistics are given
regarding the production of the two
metals in Missouri, the prices received
from year to year, and the total output
of the various counties.
The third part is an account of the
Missouri mines, with a systematic and
detailed description of the important
developments and occurrences of lead
and zinc. Three districts are recog-
nized-the southeastern, the central
and the southwestern. Here is incor-
porated all the detailed information
concerning the various camps. Many
of these are mapped and the workings
of typical individul mines are plotted.
This is the portion of the work which
will appeal most directly to the people
actually engaged in working in the
