COPPER PRODUCTION
 FOR 1917 EXCEEDS
 HALF BILLION DOLLARS

The production of copper in 1917
 was slightly less than in 1916, accord
 ing to preliminary figures and esti-
 mates collected by B. S. Butler, of the
 United States Geological Survey, De
 partment of the Interior, from all
 plants that make blister copper from
 domestic ores or that produce refined
 copper. At an average price of 27 cents a pound the output for 1917 has
 a value of S510,OOO,OOO, as against
 values of S475,OOO,OO0 for 1916, and
 S19O,OOO,OOO for 1913.
 ] The figures showing the shelter production from domestic ores repre- 1ent the actual output of most of the companies for II months and the esti-
 mated output for December. A few companies gave no figures for Novem-
 Der but furnished estimates of the combined output of November and De- cember. The production of blister and Lake copper from domestic ores was 1,89O,OOO,OOO pounds in 1917, against 1,928,OOO,OOO pounds in 1916 and l. 224,OOO,OOO pounds in 1913.
 The output of refined copper (elec- trolytic, Lake, casting, and pig) from primary sources, domestic and for eign, for 1917, is estimated at 2,362, l 100000 pounds, compared with 2,259,- 1. 100000 pounds for 1916, and 1,615,- i 100000 pounds for 1913. i
 According to the Bureau of Foreign 1 and Domestic Commerce, the imports i of manufactured copper of all forms | for the first 10 months of 1917 amounted to 46O, ,7S0,O0O pounds, as against 397 7,594,OOO pounds for the first 10 months of 1916. The imports for thfe year 1916 were 462 1885 ,000 pounds.
 At the beginning of 1917 about 128,- 100000 pounds of refined copper was in stock in the United States. By add ing this quantity to the refinery out ptu of the year it will be seen that the total available supply of refined cop per, exclusive of secondary copper, was about 2,49O, 100000 pounds. By from this quantity the ex- ports for the first 10 months and the exports for the last two i and assuming no change in stocks, it will be seen that the supply il available for domestic consumption in 1917 was materially less than the l. $ i30, 100000 pounds available in 1916.
 The average monthly quoted prices f 1f copper in 1916 and 1917 were al- f most exactly the same, PIP cents a pound. The average quoted prices in 1 1916 was about 2.5 cents more than [ he actual average price received. The actual price received in 1917 was z nearer the average quoted price. z
 Arizona produced 687,8OO,OOOI s pounds, slight decrease from the e production in 1916, which was 694,- t |O0,O0O pounds. V
 Montana produced 27S,OOO,OO0 c pounds, as against 352,OOO, 900 pounds n 1916. V
 Michigan produced 275,000,000 T pounds, an increase over the 269, ,794,- le 100 pounds produced in 1916. i
 Btah produced Z45,OuO,OOO pounds, i IS compared with 232,OOO,OO0 pounds ( n 1916. c
 Nevada produced 110,000,000 ( pounds, an increase over the 100,800,- f 100 pounds produced in 1916. c
 Alaska, with a production of about 2 2, 100000 pounds, showed large de- .rease from the previous year.
 New Mexico increased its produc- ion to 1O4, 100000 pounds from 79,- 100000 pounds in 1916
 The production of California was above the 43,400,000 pounds produced in 1916.
 The production in Tennessee did not iffer greatly from the production in o16 which was IA 50O OOO mounds.
