A writer in the Mexican Investor gives some valuable information with reference to the prospectors' chance in the Yaqui river country. Among other things he says that the history of the entire mining areas from which the tributaries OF the Yaqui take their rise as we'll as the Yadui delta itsef. would seem to justify the conclusion that exploration and development should disclose comparatively large gold-bearing areas in that region. Nor would t be any surprise to those familiar with the mineralized region here referred to. and also those of the Sacramento, if the Yaqui delta should disclose free gold deposits upder intelligent ex- pioration and particularly so under dreige operations. The river bot tom below Los Hornos, i. e.. below the western foothill belt, is accessible to such exploration at least for eight months in the year. Important point CTS should be available by this time regarding facer washing generally at Cumuripa. some 75 miles from Torin the leading commercial center of the Yaqui valley. The parties oper- ating at CumuriDa are Americans. It is known that they inaugurated work by starting rp dry washers" which they subsequently, abandoned for reg ular hydraulic methods. But ve-y little authentic news is. however. avail able from there. which scarcity, some tines. al least, implies that those on the ground floor" have a good thing. What is required. however. to de- termine the availability of the Yaqui liver banks for gold dredging opera lions is systematized banning" from surface to bed rock wherever avail able. or the sinking of shafts or test ing holes, for given distances of from , to 20 miles Such tests would speedily determine whether CT not ;he rive- bed or it's immediate ebmank ments afford sufficient inducement for the requisite capital necessary to in. trodpce dredgers.
 The feasibility from a business point of view, being established by practical ari thorough prsiminary tests. iE the Yaqui valley; the ma chinery. etc. of the dredgers can be forwarded by direct steamer or rail from San Francisco to Guaymas, from which the YaQui river is distant only 30 miles by water. The dredges cohld be set up at the mouth of the Yaqui on the Gulf of California. and during the period of high water easily float ed 10 their destination at any point 40 to 90 miles inland. Probably Pptam or the vicinity of Torin would akord as good preliminary starting points as any. So much for the pos siple placer fields of the Yaqui river delta.
 As regards quartz or lode mining, it becom2s different problem entire ly. Frequent reference is made to mining operations in the Yaqui valley. while. as a matter of fact, the real Yaqui delta is not the scene of any great mining operations at all. The term Yaqui valley has become a con- venient synonym for various locali- ties in which mining operations are carried on, located on the respective tributaries of or generally above the junction point of the Yaqui. This is some ten miles below Suapui, dis trict of Ures. At this point the Yaqui receives the waters of the Rio Mocte- zuma and the Rio Bavispe. which have previously been re-enforced with their own numerous tributaries. The ele- vation here is about HOO feet, dis
 ance from the mouth approximately 200 miles. The proper starting point For these upper regions onthe Yaqui river. when the traveller is once in the valley proper. is Cocorit, some 75 miles from the gulf, where the guides and needed camping outfits (except tents) may be obtained. The Guay-
