THE MINERAL INDUSTRY OF NEBRASKA 333 from the manufacturers. About 75% of the cement was shipped by truck; almost all of the remainder went by rail. Clays..—.Nebraska's small clay output fluctuated in the 5 years (1975-79). Production increased modestly in 1979 from that of 1978, the lowest in the 5-year period. Meanwhile, the value of produced clay increased during the biennium to the highest level of the period. This was a consequence of almost steady growth in the unit value of clay from just over $2 per ton in 1975 to almost $3 per ton in 1979. Four producing firms mined common clay and shale in Cass, Douglas, Jefferson, Lancaster, and Sarpy Counties in the southeastern part of the State. Face brick and common brick were manufactured in Douglas, Lancaster, and Sarpy Counties. Lime.—Output of lime by Great Western Sugar Co. during the biennium was less than that in the 3 previous years. The value of lime also fell below that of 1975 and fluctuated irregularly during 1976-79. In 1979, lime values rose to the highest level experienced after 1975. Lime was prepared in kilns at the firm's sugar plants at Bayard, Scottsbluff, Gering, and MitchelL The output of lime relates generally to the size of the sugar beet crop to be processed to sugar at the firm's four plants, where lime is used to generate carbon dioxide and as a purifier in the refining process. Limestone for the industry came from the firm's quarry~near Horse Creek, Wyo., and from a commercial supplier in the vicinity of Rapid City, S. Dak. The firm requires stone that contains a minimum of 95% calcium carbonate. Sand and Gravel.—Sand and gravel led all raw mineral commodities produced in Nebraska during the biennium both in quantity and value. Although output in the biennium was reduced from that of 1977, it exceeded by far that output in 1975 and 1976. The value of the output, on the other hand, experienced continued growth during the biennium to more than $33 million in 1979, almost twice the total value in 1975. Growth in value was supported by the increase in output and the increase in the average unit price of sand and gravel from nearly $1.50 per ton in 1975 to $2.04 per ton in 1979. The combined output from Douglas, Saunders, Hall, Cass, Madison, and Buffalo Counties in 1978, and the output from Douglas, Saunders, Dodge, and Hall Counties in 1979 exceeded 35% of the State's total output of sand and gravel each year. One hundred and sixty-five firms produced sand and gravel in 1978. In 1975, 153 firms were active. That year, two firms supplied about 30% of the State's sand and gravel, and more than 50% of the State's output came from the combined output of seven firms. Sand and gravel was recovered in 69 counties in 1978-79, from 263 deposits in 1978 and 237 deposits in 1979. Individual company output both years ranged from less than 200 tons to more than 2 million tons. Fifty percent of the output of sand and gravel in 1978 was from deposits that yielded less than 100,000 tons during the year. In 1979, about 40% of the output came from 206 deposits that supported operations in the same size range. By contrast, almost 35% of the output in 1978 came from deposits that individually yielded over 200,000 tons; in 1979, 14 deposits in that production category provided nearly 40% of the State's total output. Thirty-four deposits yielded 100,000 to 200,000 tons in 1978, and 17 had similar yields in 1979. The distribution of streams and associated deposits of sand and gravel in streambeds, flood plains, and alluvial terraces relate directly to production. Sand and gravel operations are prominent along the Platte, Republican, Niobrara, Elk Horn, Blue, Big Sandy, and many other rivers, and in the interstream areas along the northern border of the State and in the western part of the State. Almost 58% of the State's total tonnage and 56% of the value of sand and gravel produced in 1978 were derived from counties that adjoin the Platte River. Output increased in 1979 to more than 68% of the State total and almost 66% of the value. Combined output of sand and gravel from counties adjacent to the Republican and Platte Rivers was about 66% of the State's total output in 1978 and almost 72% of that in 1979. Relatively large production from the counties adjacent to the Platte and Republican Rivers was achieved because of the abundant presence of the materials, the presence of at least 11 of the major cities in Nebraska, including Omaha, in those counties, and to the traditional use of the Platte valley as an eastwest corridor across the State for construction and maintenance of railways and highways. These factors supported abundant construction and heavy demands for sand and gravel, a primary construction material. Major uses of sand and gravel are as aggregates, roadbases, fill, concrete products, plaster and gunite sands, snow and ice control, and railroad ballast. Construction aggregates, the largest single use, required almost 49% of the total output in 1978 and
