Arizona, which ranks fifth among the states in size Qand area 113,olO square miles) and 46 in population (334,162 in 192O), ranked twelfth in value of mineral products for 1919' says a census bureau bulletin. The state ranked 18th in the total num- Der of persons engaged in the mining industries and in the average number of wage earners employed.
 The gross amount received for pro- ducts by the operators of all mines and quarries in Arizona in 1919 was ssS,47S,111, which includes duplfa- tion of $1,52S,056, representing the value of copper ores sold by some pro ducers and resold or used after treat ment by others. Thus, the net value of products was $S6,950,O55, which was an increase of 164.7 percent over the corresponding figures, $32,847,2 ,26O, for 1909. The amount given as value of products includes $752,152, which was received for mineral by-products, for customs milling, power sold, and miscellaneous services performed for other enterprises.
 The value of products reported for the precious and base metal mining industries in 1919 includes the net amounts received for ore concentrates, cement, copper, and bullion, by mine and mill operators, or the estimated equivalent of sales value when the | products were further treated and not sold, and does not represent the value fthe metals produced or recover able from these materials by smelt- ing and refining. The preceding cen sus of mines and quarries included statistics on smelters operated in con- nection with copper mines in Arizona and, therefore, thevalue of products f and also other items relating to the cooper industry in this state, reported for 1919 and 1909, are not entirely comparable.
 Mineral by-products were reported as follows: Manganese ore from a silver mine, silica from limestone quarry, and rare metals (tungsten) from a copper mine.
 Copper is the leading mining indus try in Arizona, and in 1919, with a net value of products amounting to ss6, ,6se, ,Os5, it represented 95.1 per cent of the net value of all mineral products in the state. Furthermore, Arizona ranks first among the states in the production of copper. The only other mineral industry of importance was gold and silver mining (lode mines), for which products valued at s, 3,523, 3,477 were reported. The metal liferous mines are widely distributed throughout the state, but were most important in 1919 in 12 districts m Cochise, Gila, Greenlee, Pima, Final and Yavapai counties.
 In addition to the operations of the producing mines and quarries consld- erable work was done in Arizona on properties which were not productive during the year. Of these there were reported 95 enterprises engaged Tn developing 96 metalliferous lode mines, one of them molybdenum mine, and the remainder copper, gold' silver, lead, or zinc mines. These en- terprises, with a combined capital ot over thirty million dollars, employed 79S wage earners and expended S3,- O78,71S for development during the year, these figures representing ap- proximately five percent of the aggre- gate number of wage earners and ot the aggregate expenditures reported for all minnig operations of the state. Corporations conducted 63.2 percent of all the mining enterprises in the state in 1919, employed 97.9 percent of the average number of wage earners, and reported 99.3 percent of the total value of products.
 Of the total number of mining en- terprises in Arizona, 10.3 percent had no wage earners and TAI percent had fewer than II wage earners each, and | these enterprises employed only 8.S
