BLACK ROCK AND REMNANT.
Hore about the Gold strike In tho Lost Mine, ore In the SIl- yer Glance, Flora,
 and others.

or mlnlHS LII tGloTS, oiuCc tooI communication, shows that they are decidedly not of retrogtade character. The stability and permanency of our mines, so far as development has progressed, are perfectly satisfactory to the we'll wisherS ot the district. The notes of the weeks development, and the present outlook for the more prominent mines being worked, need no comment.
 THE BLACK ROCK
 The Bailey shaft has attained a depth of TO feet, now in ore, which body continues to surface. the extensive dump of first and second class ore attesting the prolific result in the opening of this mine. Too much praise cans not bp accorded the superinten- dent, Franklin J. Clark, for the rare executive ability displayed in successfully bringing this property to it's present standing as bona flde ore producer: for the ban of young mining camp is the lack of management. It has swamped many mines, and laid au oppressive weight ou T district which it has taken years to lift. The development of one or two mines generally makes or mars ths future of 8 camp. Hence, those in charge of such development can be of benefit or curse to a community.
 THE REMNANT
 Work continues on the vertical shaft of this property. and 40 feet nearer hades than the wind lass men, who are hoisting @ quartz porphyry dirt. A force has been put on the ore shaft. which is heinz driven through ore. and 40 feet of rope required to reach the bottom. Cool vent. illation has been secured since the drift from ore to Disc overy shaft was completed. Work will continue, uninterrupted by the pending law suit. As it is con- trary to the writer's idle, of the duty of mining correspondent to deal in matters of a private nature, he will not inflict a long suffering public with his private opinion in the Remnant struggle for a fractional interest in that now valuable property.
 THE LOST MINE. Lees contract on tha adit, being run to connect with west cross cut, has been driven 30 feet, with day and night shifts crowding the work. The assays from averages of the 59 feet in width of cross cut, by Prof. Julius Seibeck, returned s13.S0, gold per ton. The returns from Tue son were equally satisfactory, seven different assays showing the value of the ledge to increase with depth, in gold. There be- ing a water power on the Colora- do river, near Yuma wash, six miles distant, with power suf- ficient to run 100 stamps or more connected with this property, if the lode hollis it's width anh value when the 20O-fOot level is reached, a stamp mill wilt be erected. The discovery of gold in this mine has stimulated the search for that metal throughout the district.
 THE SILVER GLANCE
 The incline shaft contract is now driving 210 feet below the surface yet Iu the soft country rock, and should be finished by next com municatiOn. Cross cut from 175- foot level continues, and ore of high grade found. Upon the completion of shaft contract the ledge will be tapped from bot tom of shaft, and it's exact posi- tion and character determined.
 THE MISSOURI
 From the 100-foot level Of vertic- al shaft the east cross cut has penetrated 30 feet, cutting tlrongh an irop qu.rtz seam, which shows on the surface, but
