 MINERAL PRODUCTION.
 Mining began in Alaska in lS80 and since that tinc Che Territory has produced mineral wealth to the value of 268OO000O or this S2f1So0.00o has been in gold Sl9S00,00O ip cop per S2,25i 900 in silver sS70.0O9 in coal and Che rest in tin lead quick silver mable. gypsum petroleum, etc. Copper minine began iu Alaska In lg0i m dtho total production is about iS2000O00 pounds
 9t is ostimated tba, the value Of che total mineral output Of Alaska in 1914 is Sl92iS00O compared with $i9,sl6000 for 1915 The preliminary figures on gold output for l9l4 show value of Sl5,900.0Q0; iu 1918 the value was Sl5626.818 Silver to the value oi about Sl91000 was produced in 1914 compared with $2lS9SS in 1918. Though the low price of copper since midsummer greatly curtailed the output of that mineral about 20- S50,000 pounds, valued at about S2,- S720o0, was produced In 19l4 against 21659.95S pounds yalucd at S8,85729 in 1918 ghe output of Che other minerals including tim marble, gyp. sum, quicksilver coal aud petroleum in 19l3 had a value of about S2S5, 900, compared with S272242 for 1913.
 Had 1t not been for the depression in the copper market Che value of Alaeka's mineral product would have been considerably greater in 191l than Tn 1913. The gold.mining industry of the Territory as a whole was pros. porous during the year. as is made directly evident by the figures on out put. but @ more Important item of progress is the extensive dead work accomplished on large plants that have not yet reached productive stage. No progress was made in coal mining there being In 1914 only one small productive mine in Che Territory and that in one Of the Ignite fields It is expected chat che new law provid-I Ing for leasing of coal lands In Alas ai will lend to che exploitation of the folds containing high-grade coal. The tin, gypsum, marble and petroleum mining industries Of Alaska had a sue. cessful year
 "The certainty of railway connec- tion wlih the Yukon basin has greatly stimulated both prospecting and min.l ing development. There was a notice able increase in investigation of large mining enterprises in 1914 compared with previous years This was due solely to the expectation of cheaper transportation.
 REVIEW BY DISTRICTS.
 Southeastern Alaska.
 ''The four mines Of the Treadwell group, in the Juneou district, were operated throughou, the year on the same scale as before in the Ready Bullion and Seven Hundred Foot mines of this group ore Is being developed on the 22OO foot level
 Aiaeka-Juneau.
 "The Aloska-Juneau is the only other mine in the district which has reached Q productive stage At this property 50.stomps of the first unit were completed in the spring. and work on che installation of the rest of the 600-stamp min was continued The main adit tunnel and raise at .his mine were completed in 1913, and the underground work in l91l was therefore devoted to the opening 3f stoping ground
 blaska-Gaatineau.
 Underground work was continued ,n large scale at the Alaska-Gastin- ,au mine during 19l4 the main adit unnel and connecting shaft having leen completed in 1915 The water bower plant on Salmon creek belong ng to the same company was rapidly iearing completion in the fall of l914 . md it is expected that the first 1,5OO- on unit of the 6,OOO.ton mill will be n operation about the first of Janu- ny
 Alaska.Ebner.
 "At the Alaska-Edner mine a g., 0Ofoot adit tunnel was completed Intended to undercut the old workings t depth Of 400 feet A crosscut was eine driven at the end of the adit D the fall of 1914 About l,150 feet I development work has been done n the Salmon Creek Gold Mining 'o's property Of which about 300 aet was done by present company. { . l5-stamp mill IS under construction.
