rack. The Central paid nearly twv millions in dividends, and worked un- til ten years ago, but is now owned by the Calumet & Hecla. The Copper Falls was a considerable producer for many years, and paid several small dividends. but on the whole was un- profitable. It is now a part ot the Ar mold mine.
 The Phoenix is notable for having produced the largest single mass of native copper ever found. this weigh ing 527 short tons. The Phoenix mine proper. which raised this big mass of
 metal, is owned by the Phoenix Con- solidated, but has been idle for many years, the operations of the company since organization eight years ago
 having been confined to production from the Garden City and St. Clalr
 mines, and to little exploratory work
 on the Ashbed amygdaloid lode:
 The greenstune, a quarter-c1ile wide
 flow of lava in the. Keweenawan sys-
 rem, is 8 promising feature of hewee-
 nav county for many miles, standing
 up one hundred to two hundred feet
 above the eastern slope, owing to its
 greater resistance to the eToding ele-
 ments of air and water. This green
 stone is underlaid, for many miles. by
 the AHouez conglomerate. supposedly
 identical with the Albany Sc Boston
 congiomerate now being worked by
 the Franklin Junior mine. The AL
 louez conglomerate is a wide and
 strong lOde,r bearing copper in varying
 quantities. 4 considerable production
 from this lode was made by the old
 AIlouez mine, and the property was
 worked at a profit by tFibuJOrs. on
 several occasions, but the company al
 ways lost money when working the
 mine itself. In eastern keweenaw
 county the Deleware mine worked g coHglomerate, but quit business after
 sinking about S3,IO0,OOO. The Dele ware is now the AauiUou mine of the
 Calumet & HecIa, but the old work iGgs are not being reopsued. Principa developments on the biauitgu, under
 the new ownership, are on the Mon tTeal River lode, which shows variable values, ranging from very good to gerJ poor. Further work will be required !, to determine the value Of this prop
 erty. At present the Kearsage lode i:
 being located on by the Manitou, ana while little can be said of the pros poets at present, the situation is con
 sidered decidedly encouraging.
 The Manitou property has a con ? tinuatiun of the Allouez conglomerate but the AIedora property of the Ke weenaw company, lying between tho ) Alloue and Manitou has no trace ot . the AlloueZ Iode-a rather puzzling sit nation for geologists to disagree over The Cliff mine property has an ex ? tensiye acreage, and is one of the mail . assets of the Tamarack, as matter: ! now stand. Some work is being done by the Tamarack company, from thu old southern shaft of the Cliff. Be cause the mine was opened on a ifs : sure vein, the old workings afford ex ceptionally good opportunities for the exploration and exploitation of the GU
 pTiferous lodes of the stratified forms tion, and in view of the highly valuablt development in the Mohawk, Ahmeel and Alloue mines, all Keweenaw eoun ty properties a short distance soutl of the Cliff, the prospects of the latter while founded solely upon general con : alterations, rather than upon specifi l developments of value, are decidedl, 3 good.
 : Perhaps the most valuable undevel : oped property in the Lake Superio t district is the Seneca mine, adjoinipl 3 the Mohawk. Ahmeek and AIIoue v A little work was done upon the St neca many years ago. and two possibl - payable lodes were opened to sligh j. extent The developments at adjoir y ing mines are of such uniformly fa1 l. orable nature that 1t would, be mos l. remarkable were the Seneca to prov g otherwise than a fine mine, of th l. same general class as the three al o- joining properties previously named l, It is the intention of the managemer If to begin development work on the S l. neca in the spring.
