 During 1919 development work was Cone on galena ores iD southeastern | Alaska, in the Seward peninsula in the Yukon basin, and p.oUably Ill other regions. In cou4se of this wo. h some ore was produced but 50 ia. as known, only d few tons of te.,t shipments were made. The inIO4na | ton at hand indicates that the IAu5t promising discovery of silyer-boaIins galena was that made in the kantish. ld district.
 The silver output of Alaska in 1913 was about 590,O00 ounces, of whic.. some 500,00O ounces was recovered
 l. om copper ores. Alaskas lead out put of 1919 is estimated to be 800 tons, practically all by-product ol the gold lode mines.
 The York district, of Seward penin- sula, continues to be the center of the tin-mining industry of Alaska Here, in 1919, two dredges and one small open-cut mine were operated cn placer tin, employing some 9 n'en. Deycopments were als> con tnued at the Lost river tinlod9 nine n the same district, where aoouo 25 men were employed. Sobe tin also .. recovered in goid-pacer mining in few )f the Yukon districts. Prt 'ifu., estimates indicate th', abou, 40 tons of metallic tin was produced d Alaska during 1919.
 No new deposits of placer tin have been discovered in the York dis trict in recent years, and there is no certainty that this form of tin mining will be continued there when the deposits now being exploited are worked out. No tin placers which, under present economic conditions,
 ii4 warrant exploitation lor tnei. tin alone, have yet been found in the Yukon districts. When costs of oper-
 
 may be developed in the Hot Springs district. The distribution of tue al luVial tin ill this district justilies tho hope that tin-bearing lodes may yet be discovered. MeanwhIle, the best nope of the continuation of Alaska tin mining Is based on the lode tin of the York district. The Lost Rive4 mine in this district is the onIy prop erty sufficiently developed to JusuIy the belief that il Will soon become producer, yet there are others Ill the district when deserve prospvct- ing.
 Some platinum was recovered ili the mining o1 placer god in the SeYard Peninsula, IoIstoI, and ChIs- toChina districts in 1yIy, but th. quantity is unknown. The LIlnlng ol copper ores at the Salt CnucK mIne, in the ketchlkan district, winch cal- ry palladium and pIatInun, Was con Llnuod, as Ill tne previous year.

 Coal and Oil
 The most important features of the | Alaska coal-mlnIng industry in 1913 ! are CD the conunudLon oI sysleA4 duc mlnlng ln tne AIdtaAuskd lIcIu Dy the AIasha EnsIneeIAus CuIulIis- | sion, lz) tue syatemauc prospecting | oI lease held ln the Berng rINel | field, and (o) the begInuIng ot th, mining ot the Nenana ugnIuc coal.
 Mining and underground eXplola- tion Was carried on thluout the yea. by the Alaska EnSlneenng comiuIo- sion at the Eska and Cnlckalou.. mlnes, ill the MaJanusKa ueId. Goa. production rom these mlnes Vas au- visedly limited to the needs of lhe . commission and nearby localities. At the Eska mine, which is a btu minous coal of low rank; about l5U, 900 tons of coal have been blocked out and some evidence has been oD- tained that there is an additional re- serve of about 1,000,000 tons. At this mine the coal beds are not great ly folded but some large faults have complicated the extraction of the coal. At Chickaloon, where there is very high grade bituminous coal, the beds are intensely folded and much | faulted. These conditions increase greatly the cost of mining. The work of the commission has resulted in blocking out about 100000 tons of coal.
 No details are yet available about . the developments made on the lease held in the western Bering River field, but extensive and systematic underground work has been done, and ,he results appear to have en- couraged the lessors to continue. The coal at this locality is high-grade
