ed States with all the tin used in
commerce, but with all the Portland
cement, according the latest claims
made BY several citizens from that
state. John H. King of Chamber
lain, s. D., who was largely interested
at one time in the development Of the.
tin mines in the Black Hills, seems.
to have. more faith. in fact, in the
development Of the Portland cement
industry, as he has sold out his in
tereat in the tin mines and placed his
capital in the Portland cement bust
ness. -, Il. s
'There is enough Gladstone and
clay in sight in South Dakota to sup
ply the trade in Portland cement in
the whole Uuited States" said Mr..
King. portland cement, you know,
is made Of a mixture of a certain kind
Of stiff clay with Gladstone. Now
the only place in the United States
where are found deposites of chalk
stone is along the banks of the Mis-
souri, Riyer-in South Dakota. In the
lodges and bluffs from five miles above
Chamberlain down to Yankton are
found rich deposites Of Gladstone
thirty to forty feet thick, and above
them are layers Of the stiff clay which
is almost the consistency Of the gumbo
ID the bad lands. This stretch Of
Gladstone deposites is only about 1875
miles long but there is enough. stone
and clay Id sight to supply the United
States, and when the quarries are
worked it is believed there will. de
found enough stone to supply the
world with Portland cement. A year
ago plant was established at Yank-
ton valued at half a million dollars.
This plant was put in operation only
two or three months ago, but it is
turning out Portland cement Of UNI
surpassed quality. a.,
"At:present the world obtains its sup
ply Of Portland cement from England
and Germany. Gladstone deposits
are found along the Thames river in
in England. But samples Of the c.
ment from the Yankton plant have
been sent to New York to be EXAMINE
ed by experts and they pronounce
the Dakota cement equal in quality
to that imported from Europe. The
United States imports from 100000
to 100000 worth Of Portland &C.
ment each year. The Yankton plant
is the only one in this country manu-
featuring Portland cement, but when
the industry is developed in Dakota
and other plants are put in operation
the $4,000, 600 which now goes over to
England and Germany can be kept in
this country" j
fare other cement plants to
be- 81 built soon?" { eyes, more
plants will be put up soon
soon as railroad facilities cab be &C
quired. Coke is required in the manu-
facture Of cement, and at present there
are no railroads touching the chalk
stone deposits north Of Yankton, and
therefore no plants can be run: north
of that place, as no coke can be sent
there. As soon as the Milwaukee &
st. Paul railroad extends its line to
Chamberlain a cement plant equal in
value to that at Yankton, will go up
there, as supply Of coke can be then
be shipped in. The Portland cement
is composed of a mixture IS per cent
Of which is stiff clay and IS per cent
Gladstone. The Gladstone is first
mixed with the clay until it fathers
and the whole has the appearance of
plaster; then it is put into bricks and
burned in a kiln, and finally is ground
up and prepared for the market.
Coke is required in burning the &C.
ment. It will not be many years be-
fore you see Portland cement from
Dakota used in the const ruction Of
fine buildings in Chicago"
