 Production of crude and marketable phosphate rock and manufacturing of phosphate
fertilizer products declined somewhat during the year but continued to represent
a substantial segment of the State's mineral industry. Activity was centered
in Caribou and Bingham Counties where six major firms were engaged in one
or more of the following operations: 
Mining of phosphate rock, manufacturing phosphate fertilizer products, or
reducing phosphate rock to elemental phosphorus. 
 The story of early mining discoveries and the history of mining development
in the Coeur d'Alene mining region in northern Idaho was published.3 
 Also, a nationwide* guide to mines or mining operations that may be observed
or visited was published.4 The pamphlet is intended to aid tourists and students
interested in mining. 
 
 Consumption, Trade, and Markets.— Most key indicators of Idaho business
activity rose during 1967. Measurements of percentage growth in total and
per capita income (7.0 and 6.7 percent, respectively) were almost three times
