The relative importance of the several dis-tricts in the production of silver is showngraphically in figure Figure 17.—Diagram showing relative importance of the principal dis-tricts of Utah in the production of silver, 1865-1916. Silver production was not large tiU about1870, when the discovery of the bonanzas inthe Cottonwood districts caused a rapid in-crease. Before the exhaustion of these depos-its caused serious depression the output fromthe Horn Silver mine in the San Francisco dis- 134 ORE DEPOSITS OE UTAH. 111 Tttt-H4-H44-l-k1 ^~ R. f ~~ - ;n ~ . ^ ^ - - -- ,,-- / . ... 1 ..__<_,,^___---------,,-^ ?? -. ^ ~~--~~--~~ - ^ ^^\.- \ ^ll:::=!=-53i=_- -- -- — -- - - - - - - - - ~ - - - - - y -- -- --- -- - - - - 1 - - - - - - - - - ?~4^ - J:, --, V I- / .-: \ \ ^^ / ^ •^ [\ ^ .- 1 -- ~- f ?- —__ ^~~-^*_ \ j_^-^ s \\ —1- \ -- - r - h - r ., i - - - - - .-^:^L^-l :^ - Z -- ~ - _ - _ - - - - - - - ~ ~ ~ ^ - _ __ : i 3- -- - - - - - ^ .__ - - - - - - - - _j ____^ — =.-_ ^ ^ :: ~~ :: ::: :: S ?* : : : : : : : : : : : : - —.^^—— ^ •? ~ ::
