Mines, in Altar Distriot-A Brief Description of the Property.

Description or the Property.
 Mir. J. R. Magruder has so long
 been identified with the mining indus
 try, and in SO many different places on the Pacific Coast, that \ CITIZEN
 reporter this morning took advantage
 of his brief sojourn a; the Palace Ho-
 tel with his family to obtain some In-
 formation for the public regarding
 his present operations in Sonora. Mir.
 Magruder does not readily respond io
 the interviewer, preferring to do hts
 talking in the way of rc>ults &C.,
 complished; but in this instance he
 responded very kindly to the solicita-
 tiOnS of ihe CITIZEN representative
 with the following information re-
 garding his present operations:
 The Coson hines are located at a
 point about6S west miles ol Altar, and 45 miles from Port Salinas, OF the Gulf of California. They consist of three
 gold mines, known a the Espuma,
 Le Bonita and San Francisco, and
 were purchased by Mir. Magruder in the summer of 1879 from C. J. Whip
 pie and Manuel Escslante, for $S0,- 900. As may be supposed, they were not bought without careful inycs-
 tigation, MT. Msgruder having visit cd the locality several times previous ly. He immediately set 10 work 10 develop the property, and no: very long ago purchased a new and first-class TO- stamp mill in San Francisco, and had il shipped by schOonerdo Salinas, from which point it is being hauled by wagon to the site. The mill has a capacity for 10 addi- tional stamps, which will be added should the water supply prove ad- equaie. IL is fitted with pans and se- tiers, NIT. McGruder deeming this method preferable to the ordinary gold amalgamating process, as the San Francisco mine carries very rich streak of silver bearing rock. The mill will cost in the neighborhood of $40, 900 when completed, the Mex ican authorities having put 4Ir. Mic Gruder to considerable trouble, by compelling him to unload the schooner at Guaymas, for the convenience of the custom house officers, and the du- ties proved no slight addition to the expense bill. It is the intention to have II running by November.
 Of the mines, Mir. McGruder had little to say, preterring To let them speak for themselves through the mill They he in different directions from tho nill-site, each being about six miles away. The E-puma has q four foot vein of free gold quartz that averages $50 per ton. La Bonita has a ven-fOot vein, but the rock is of lower grade, and will not mill higher, it is believed, than S25. The San Francisco is of an entire different for nation, having twelye-foot vein of low grade gold quartz. The ledge, however, has rich 21s-foo, pay streak of antilnonial silver next the loot wall, which averages very high. The mill will be run for some time on rock from the two former mines, though the work of development on the San Francisco will be still con- linucd. Mir. Magrudcr estimates the ! cost of working tue ore at sS. 50 per ton.
 Although yet young man, MT. ! has been prominently iden- flied with the mining interest for a 1 number of years. He | built the first mill ever erected in ilobe District, and the second smelter aken into Leadville, besides being ac- lively connected with many other pro- ects. not only in Arizona and Colo 'oadO, but in New Mexico as well. His present venture will succeed, if ,ool judgment, experience and intel igence have any weight in the mod ,rn race for riches, and the CITIZEN gives Mir. Magruder a hearty God peed.
