CENTENNIAL
We are informed that Centennial is gradually cutting
down its force of underground workers proposes To
further curtai operations pending improvement in
the metal market Operations Centennial for some
months past have been extremely discouraging The

stany in mineral both shafts on the Kear
sarge lode attained epth, improvement was noted
although the ground No. shaft gave fair re-
suits. Centennial has been operating at loss and IL
already handicapped with an Indebtedness which has
been growing with each month. curtailnent of de-
velopment would change this condition of affairs
and better prices for copper were obtanable
the company will probably operations on a more
extensive scale.
