THE SONORA MINES.

.
 are Treated by Mexicans, and the Prevalent Feeling.
 , For some months past our citizens and some from other parts of Arizona, ) and from California, too, have been
 going and coming from the mines just across our national border. As
 about all discoveries within our knowl-
 edge, equally truthful mems reports
 differ. Without attempting to recon
 cile the reports, or referring to other
 incidents, THE CITIZEN will now give
 some useful information to those look
 ing that way for business, and what reliance can be consistently placed
 upon the average of reports. Within @ week, Messrs. John Davis, A. Linn,
 John Burt, J. l.. Stephenson, I. J.
 Rolfe and others have returned to Tucson, and nearly all will soon go
 back to the mines. From Mir. A. Linn, we get most of the absolute statements of this article, and 1t ought to be added that others confirm them.
 The mines so far as discovered and rediscovered, are in Sonora from six to fifteen miles beyond the national
 boundary, by the most careful esti- mates from several of the monuments. The discoveries seem to increase tow ard the line, and some very promising ones have been made in Arizona-as the discoverers believe. But right here it should be said that the mines are not silver placers. A few pieces of placer silver have been found, but more of what is called pure silver is found in thin flakes running through quartz, lime, and other formations, some appearing in 8 conglomerate of rocky substances.
 But two or three defined veins are yet exposed to view. Comparatively little work has been done or depth at tained on any of the discoveries, and any judgment regarding the size or other character of the veins, at this time, would be unreliable. Some of the claims have two or more very rich strata of six or more inches in thickness, separated by @ few inches of earthly and rocky substances. De velopment may show these strata united into well defined, fair sized veins at no great depth.
 The country for fifteen to twenty miles about is one bearing gold and silver--the latter largely predominant ing. Discoveries of mines formerly worked, as well as those never touched, are still being made, and confidence in their value at this time is increasing.
 One man may take up and have re- corded 200 yards; two men or con- pany of men, may take up and hold 500 yards. Claimants are allowed 100 yards on each side of the center line of their vein; or if deemed bet ter, 90 yards OF one side and 15O on the other-that is, 200 yards in width to the best advantage of the mine. All claims must be recorded, and on old mines, sixty days are allowed in which to sink thirty feet-an amount of work to be done upon all mines at an early day. For good cause shown, the authorities may extend the time for doing this work, After the pre- scribed work is completed, the public surveyor makes @ survey, and the claimant must then select and clearly stake out the ground he prefers; but I'D to this time he may sink shafts and do work at any place along the vein he chooses, that he may the better de- termine what part of 1t will best re- ward him for tho discovery. After record and survey, some work, about -or days, must be done every four
