oxide, and of native copper occur also ln the midst of the abundant kaOlin clay left by the alienation of the gran ite and porphyry by the passage of acid cupriferous solutions, derived, no doubt, as at Copper Basin and at the other localities, by the oxidation in sitl Of punches and lenticular masses of copper sulphide originally present as a constituent of the crystalline rocks, either in lenticular punches of the seg- regated type or diffused in the mass of the rock.
 ARIZONA COPPER COMPANY
 There is probably no town in the territory of Arizona today so peculiarly situated as is the town of Clifton. Up in dark deep canyon, whose perpan- dicular walls rise to a height of several hundred feet lies the seat Of one of the largest copper camps in the world.
 Tn width the canyon is about 200 feet, and the San Francisco river runs through it's center. It is the dividing line between what might be very paop- erly called the two towns. On the west bank are the company's store, works, offices, etc, while the residences of the employees and the business houses oc- cupy the east bank. The Arizona Cop per company is the life-giving factor to the town of Clifton. Without it Clifton would not exist. This company has invested upwards of S3000 000 in mines, railroads, reduction works, and appliances for making the ores return a revenue.
 ''The company employs more than 300 men and distributes $35,000 per month among it's employees, as shown by the pay rolls.
 Af crushed every thirty days, and the pro- duct from this enormous pile of ore is 500 tons of cure copper bullion.
 Here it is co centrated to 1 per cent and is then subjected to a teaching pro- cess which leaves but 11a per cent of copper in the refuse.
 ''The ores are transported from the mines to the works by means of "a 7-asr- TOW gauge railroad, the distance be- tween the rails being twen1g-six inches.
 The best of the clatpas at present, probably, is the D4etcalf Although it has been steadily worked for twelve years, there>ts still ore enough in sight to keeR machinery in operation for an indednite time. Ore is also worked fI8m the Longfellow, which has always nbeen a noted producer. Recently I number of claims, which were hitherto looked upon as non-producers, have been opened up and are surprisingly rich.
 ''The present plant of the Arizona Copper company consists of four smeIt- ing furnaces having a capacity of 400 tons a day; one sulphuric acid plant, capacity eight tons per day; one slice ous ore concentrating plant, with a capacity of 150 tons per day The out put of this company five years ago was equal to about 5000, 600 pounds of copper per year. In 1895 it had almost doubled, amounting to Il ,5G0, 900 pounds, and in 1896 exceeded all of it's previous records by producing l3.000,- 900 pounds Over half the output is from concentrating and teaching ores, and ores as low as 3 per cent in copper are treated at a profit. * $ The out put of copper bullion in Graham county for 1897 was estimated at 25,0O0 GOO pounds.
 MORENCI-DETROI COMPANY. !
 This copper producing camp, the ! home of the Detroit Mining company, | is seven miles from Clifton and l 1.500 | feet higher. This company has a fine i plant for concentrating and 5meIting f copper ores. The pneumatic process has been introduced and the output for 1 1897 was estimated at about 75O 900 | pounds monthly.
