The ore occurs in lenses and with good copper indi-cations. It is now idle, although considerable work has beenperformed upon it. The copper belt extends south of Daulton to the San JoaquinRiver, the countys southern boundary. It can be tracedalong this inter\al and its course proven bj- croppings, cuts,and shallow shafts, but thus far no important openings havebeen made into its depths.

From a point ten ortwelve miles directly east of Madera copper-stained rockappears continuously into Fresno County. The formation inwhich the masses of iron and copper sulphides occur is practi-cally the same, viz., a meta-diabase. The grano-diorite followsalong as an east wall. In Sees. 23 and 26, T. 10 S., R. 19 E., on patented landowned by Mrs. L,- Krohn, J. H. Ward was developing underbond an old claim which was originally taken up for copper ore and indications of a deposit were obser\ed. Adobe Ranch.—^.The croppings lead into what is knownas the Adobe ranch, owner C. S. Moses, in T. 10 S., R. 19 E.,comprising thirty-five sections of land, and nine miles south ofDaulton. There are several places on the ranch where 30 percent copper ore is said to have been taken out. One local peculiarity of the belt in Madera County is thepresence
