sonry cement. Portland cement was shipped to users in the following proportions
in 1978: ready-mix companies, 77.5%; concrete products manufacturers, 9.5%;
highway contractors, 8.4%; building materials dealers, 2.8%; other contractors,
1.8%; miscellaneous users, 0.1%; and government agencies, 0.01%. Distribution
in 1979 was approximately the same except for a slight increase in the amount
shipped to concrete products manufacturers and a small decrease in the amount
shipped to highway contractors. About 85% of the cement shipped from plants
to terminals was made in bulk by barge on the Missouri and Mississippi Rivers.
Conversely, about 95% of the shipments of portland cement to consumers during
the biennium was transported by truck. Rail shipments comprised approximately
5%, and barge shipments to consumers were insignificant. 
 Gulf & Western's Marquette Co. undertook construction of a new 1-millionton-per-year
cement plant on its Cape Girardeau property. The firm planned to complete
this new plant early in 1980. The new system would contain, redesigned quarry
operations, a primary crusher in the quar-~ ry, an enclosed conveyor system
to the storage bins, a continuous-blending system, a reinforced suspension
preheater of Japanese design, a new grate-type cooler, clinker storage bins,
a finishing mill with special mill-discharge dust collectors, and a Raymond
coal mill and system to deliver coal both to the discharge end of the kiln
and to a calciner in the preheater tower. The cost of the expansion was estimated
to be $78 million. In 1979, the River Cement Co. plant at Festus was sold
by Missouri Pacific Corp. to IFI International, S.A., of Italy for a price
of $78 million. 
 Shortages of cement and accompanying high prices that appeared in 1978 during
a period of maximum production in Missouri were blamed on price fixing and
restraint of competition among the manufacturers. Allegedly, customers and
territories were allocated to certain companies for the sale of cement, and
customers were classified according to eligibility to buy cement. A suit
was filed in Federal court in Jefferson City charging such restraint of trade
and naming 15 corporations as participants. Alpha Portland Industries, Inc.,
Dundee Cement Co., Marquette Cement Co., Missouri Port- 
land Cement Co., River Cement Co., and the United States Steel Corp., all
producers in Missouri, were among those charged. The Missouri case was transferred
along with similar suits from other States to Federal court in Arizona. In
August 1979, River Cement Co. of St. Louis agreed to make payments in settlement
of the antitrust charges.

 Clays.—The clay industry of Missouri, the source of a variety
of clay
products, experienced a fluctuating but distinct upward trend in production
from 1975 to 1979. Output of clay in the latter year was more than 8% above
that of 1975 and the second highest recorded in the 5-year period. By contrast,
the value of produced clay, rising annually through the same 5-year period
except in 1978, reached a record high in 1979 of more than $20.5 million,
about 55% above the value in 1975. The average unit value of all clays rose
correspondingly from about $6 per ton in 1975 to $8.73 per ton in 1979. Produced
clays included common clay and shale, fire clay, kaolin, and fuller's earth.
Missouri led all other States in the quantity and value of fire clay produced
in 1979, but ranked 9th in output and 10th in value of all clay and shale
that year. 
 In 1978, 28 firms obtained clay from 86 mines. The following year, 26 firms
mined at 65 sites. About half of the State's output
