washed and screened the salt into fine and coarse granules. The fine granules
were used as livestock feed, either in the form of pressed blocks or as loose
material mixed with other feed. The Salt Supply Co., Inc., supplied salt
for a variety of uses including livestock feed, highway deicing, oil refining,
and water softening. Output was shipped to users in Arizona, Colorado, New
Mexico, Oklahoma, and Texas. 
 
 Sand and Gravel.—Sand and gravel operations in the 32 counties totaled
165, compared with 177 in 1966. Although output of sand and gravel decreased,
value increased 10 percent, or $1.3 million to $14.3 million. Value of shipments
ranged from a few thousand dollars each in Curry, Hidalgo, Lincoln, and Union
Counties to over $1 million each in Bernalillo, Dona Ana, Luna, Mom, Sierra,
and Valencia Counties. Government-and-contractor operations accounted for
79 percent cf output; the remainder was prcxluced by commercial operators.

 Of the total sold or used, 78 percent of the sand and gravel was washed,
screened, or otherwise treated. Portable processing plants were used at 54
operations, stationary plants at 33, and both types at seven. 
 Highway construction accounted for 91 percent of the 13.4 million tons of
gravel and 33 percent of the 1.3 million tons of sand produced. Most of the
remainder was used in building construction and as fill. 
 The following government agencies used sand and gravel: Bureau of Indian
Affairs, Bureau of Public Roads, Forest Service, U.S. Army Corps of Engineers,
U.S. Atomic Energy Commission, New Mexico State Highway Commission, Arch
Hurley Conservation District, and several county and municipal highway departments.

 Accounting for 14 percent of total output, 57 out of 88 commercial operations
had production of less than 25,000 tons of sand and gravel. Two operations
in the 400,000- to 500,000-ton-per-year class accounted for 28 percent of
the production. 
 Hites Sand & Gravel of Roswell was the only producer of industrial sand.
Output consisted of a small amount of blasting sand. 
 Plans for new highway construction 
interstate highway in New Mexico; 623.1 
miles were open to traffic at yearend; construction was under way on 99.5
miles; 
engineering or right-of-way work was in 
progress on another 211.7 miles, and only 
64.1 miles had no work in progress. Total 
1968 planned highway contracts for about 
$45 million were about the same as in 
1967. 
 
 Stone.—Production of stone decreased nearly one-half, and the value
of produc~ tion declined $1.7 million to $2.4 million. There were 57 operations
in 23 counties. This compared with 71 operations in 24 counties in 1966.
The output of stone, as well as sand and gravel, fluctuates yearly as a result
of changing construction activity. 
 Most of the output was crushed limestone and crushed miscellaneous stone
(649,191 tons and 595,159 tons, respectively), followed by crushed sandstone
(74,202 tons) and crushed basalt (69,134.
