 DEAR SIR:-I have to report the fol- lowing progress for the week ending August oIh: South crOss-cut from west lateral drift, driven l2 feet, tstaiA 96 feet; face in more favorable ground and beginning 10 show iron stains.
 Protection Tunnel, west drift (back vein, tunnel leveD driven fl feet, total 34 feet. Protection Tunnel, east drift, (back vein, tunnel ieveD driven r feet. total r feet. No change to report in either of the drifts. Faces of each in ore.
 Gardner Tunnel, driven 20 feet, to- tai 126 feet.
 Revolution Tunnel No. ?, (l50 feet vertical below Protection Tunnel) driven feet, total 43 feet.
 We are upraisins on large body oi low grade ore in west drift from cross cut at bottom of No. back vein.
 No , still shows a large width Of $l0O ore Tn west drift, first level.
 The west drift from bottom of No. ' is producing a considerable quantity of ore which assays S54 ln silver and some gold. Stoping m Salvador mine, and have moved about 50 tons of this ore to main chute, as tine stopes are filled with ore.
 We have been obliged to suspend work in the west drift from No. f. as in breaking back into the veia to open backs over our stn!ls, we have filled the level with ore which cannot be moved un.ii We can empty ore-blns at the mouth of Protection tunnel and cleau out our main ore chute. We are now moving about 70 tons daily from the nre bins and will be in shape to Smp av rage grace ore about the , 18th iIst. 1 ind 1t necessary to line ! our maiu ore chute with iron, as the dust from the fine ore works m clouds | into both the ll5foot and tunnel lev ! els, and today compelled Us to close the first level l tmuk it also advisa- able Co enclose the ore platform at the mill and orc-huuse at the mine, as the wind blows away a great deal of the ] fine chloride in loading and unloading ! the quartz teams.
 The general outlook at the mine is good.

 The mill is working admirably, and it is first class job. can see no | fault whatever. nor even room for i'm movement MT. J. B. White, the su- Derintendent of construction, Is enti- fled to great credit for his very thor nugh and wOrkmanlike job. 2.-. A.. ! Hoover, my mill foreman and anal camator, is working this low grade ore to an average Ui 90 per cent of battery assay, our lowest result since starting being S5 plus per cent, and this with very small percentage or salt. We gre still experimenting with the ore. and ii will be about the 18th before we get down to any thing Ike regular work slime and quicksilver pumps will be in tonight.
 I see no resson 10 doubt very com plete success in both mine and mill, and as soon as possible, under instruc- lion from Mir. Higginson, the Presi- dent. will put the mill steadily at work on the best grade of ore which the mine can regularly produce with out straining its reserves.
 Yours truly,
