Judge Hallett's Views.
Saturday morning the owners of the Raven property at Cripple Creek applied to Judge Hallett at Denver for an injunction against the striking miners to prevent them from in any way interfering with the mines.
Judge Hallett refused the injunction. His opinion closed as follows:

"I must say that it is my opinion that the peace and good order of society in this state is committed entirely by the constitution of the United States and by the constitution of this state to the authority of the state.
If the government of the state has fallen into the hands of socialists as it certainly has, or of imbeciles, as is probably true, that is our misfortune, but we do not thereby acquire the right to assume control of affairs on the part of the federal government."

RAVEN.—This company is erecting a large sorting house and ore bins, and is making preliminary arrangements to sink a deep vertical shaft on the Gregory claim.
As soon as the sorting house is completed, a large number of men will be employed in stoping the reserves already blocked out and in development.

The Cripple Creek correspondent of the Rocky Mountain News writes his paper as follows.

The Raven Mining company, with properties on Raven hill, is preparing for a more vigorous working of its claims than ever before. A main working shaft has been started among the little nest of holes that were sunk by lessees last year that is to be put down 800 feet, at which point it will connect with the tunnel, which is being put in from Squaw gulch by the Raven Tunnel company. The stockholders are almost identical with those of the Raven Mining company.
The tunnel is in at present about 700 feet, and has recently been put in first-class shape. To-day a contract was let to extend it an additional 200 feet, but the works must be completed within thirty days from date which is very rapid driving. Machine drills are being used.
Before the bore will reach the point where the shaft is being sunk it will have a total length of a trifle more than 1,500 feet. The new find of high grade ore is turning out even better than was expected.
Returns from the smelters show that in carload lots it averages, without sorting, better than $1,100 net. One car of high grade is now being saved that assays better than fifty ounces.

RAVEN COMPANY.—This company is doing considerable work on its several properties. A contract was let to a Mr. Campbell to drive the Raven Hill tunnel 800 ft. from its present face 600 ft. from mouth. The course of the tunnel has been changed. At the mouth of the tunnel is a four-drill compressor.
The machinery for the new shaft on the top of the hill, which is supposed to strike the tunnel at a depth of 800 ft., has arrived, and will soon be at work.

Raven.—At this mine the sinking of the main or working shaft by three shifts has been resumed be low 150 ft. This shaft will be pushed continuously to 800 ft. depth, when connection will be made with the lowest tunnel, which has already penetrated Raven Hill from the north 1,120 ft.
The mine is yielding its usual quota of ore.

Raven.—This mine, on Raven Hill, last month produced 400 tons of its usual grade of ore varying from 1½ to 4 oz. gold per ton, nearly all of which was treated at Gillette mill.
The tunnel has pierced the hill from the north 1,160 ft., and satisfactory progress is being made with rock drills.

Raven Mining Company.—This company, owning the Raven mine on Raven Hill, is doing development work on a fairly good scale.
The main shaft has been sunk 300 ft., the tunnel is being driven by machine drills by six men, winzes and raises are being pushed to communicate with the levels.
The middle tunnel is also being worked, so that the reserves are always being increased. The mine employs 57 men.

In the Raven mine the length of the ore-shoot is from 100 to 240 feet, pitching 65 degrees to the south. The pay streak changes about from foot to hanging wall. Free gold and telluride are visible down to 460 feet. The vein was not oxidized whilst in the adjacent Walter, owing to oxidation, the tellurides are undergoing decomposition with free gold as a pseudomorph occupying the form of the original telluride crystals as a result. Walls are well defined vein, 4 feet wide, swelling to 10 to 12 and even 16 feet. Slickensides or striae are common with bright metallic luster, showing much upward or downward movement. The striae are like corrugated iron on a small scale. The rock is breccia. This vein differs from the others, being unoxidized, and changes take place in the vein daily, while the other veins follow the line to the dyke. This dyke follows the vein 600 feet.
FIG. 4. LONGITUDINAL SECTION OF RAVEN MINE.
It is the only vein having an ore shoot pitching south and the only one showing slickensides. The character of the ore is different, containing less quartz and fluorite. In the Moose the vein is N. 12° W., dip 80° E. by N., two ore-shoots, one north and one south of the shaft. The north shoot pitches north at an angle of 82° whilst the south pitches north 68°. The shaft is sunk 650 feet, at the bottom is the probable apex of another ore shoot. Water stopped work. This is one of the few mines of the camp yielding silver largely, as well as gold. Two carloads from south ore-shoot yielded 54 ounces gold, 114 ounces silver, the silver is part native. Average silver value is 85.00 per ton.

RAVEN.
An unusually heavy production was made from the Raven mine last week. Of late it has been running at from 50 to 60 tons every seven days, but the last report from the property is 150 tons. The ore was of various grades.

• Colorado School of Mines: ⊞ Mining and Metallurgical Journal, Vol. 20, 1898-1899

Last week's shipments from the Raven were as follows:
From the Gregory, 104 tons,
From the Raven, 30 tons,
the ore running about as usual.

George Bernard and associate lessees, who recently secured a long-time lease on the Elkton, has opened a new orebody in Raven territory north-west from the main shaft by a cross-cut at the 100-ft. level.
This territory was productive above 600 ft., and the Elkton company was unable to prospect the ground on its own account through adverse financial conditions.
Royalties paid on ore shipped are expected to place the finances of the company in sound condition.
