 llieved and denounced as stock job for the purpose of bilking some one. 1 therefore determined to find out the truth of the matter so as to enable me to report the fact truly aud in telligently to THE CITIZEN With this purpose in view I proceeded to Me Millenville to see the bonanza, if there was one to be seen. I arrived there late in the evening and called on MT. Freeman, the Superintendent. Mir. Freeman received me very kindly and told me to call up at the mine in the morning at 8 o'clock, and he would be there and show me through all the workings of the mine When the time came 1 was on hand promptly, but did not find MT. Freeman, he had been called away on important business to the mill, but had told MT. Dodge, the foreman, who we found to be a very clever gentleman to take us down the shaft, and he spared no pains to show us every crevice in the mine I must say that I was surprised and agreeably too, for it is truly wonderful strike and cannot we'll be overrated. It is | by far the most important and grand est development that has ever been made in the Territoy, and I dare say on this coast, the Comstock not ex- cepted, and to prove this statement l will forward to THE CITIZEN office for inspection two samples of ore with this letter by express. No. the black specimen assayed by MT. E. O. Ken nedy reliable sssayer, carries 12,605 ounces of silver per ton. Specimen No. 2 is not quite so rich, but rich enough to make the poorest miner that treads Arizona soil today, peer of the Rothchilds, and that to in a very short time.
 The developments on the mine at present are as follows: The incline on the stratum out of which so much rich ore has been taken is now down 125 feet, and from the bottom of this they have run a tunnel northwest 36 feet, and struck the main vein at al depth of 127 feet from the surface, and it IS in this tunnel where it strikes the mother vein that this rich deposit of ore has been struck. They have penetrated the mother vein at this point If feet and are still in pay ore. The ore consists of three grades, the first-class is black sulphide and runs over S10,000 per ton; second-class ore is being worked at the little mill byI Mir. Tidwell, and yields about six hun ldred ounces per ton; the third-elass ore they are riling upon the dumps which gives a result by assay of over one hundred ounces per ton, and of this they have already perhaps twenty five tons since the strike. The mill is kept running night and day on sec ond class ore, and they are cleaning up on an average about six hundred oun- ces every twenty-four hours. Of the firstclass ore they have shipped this week five tons to San Francisco, which f. 1 consider is worth at least $10,000 per ton and perhaps $15,000, but at this very near positive estimate it makes the grand total of $50, This class of ore lies in stratum against the foot wall and is two and half feet wide. Next to this five and half feet wide lies the second class, the remainder of the way asI far as gone is the thirdc-lass, and there is no telling how wide the vein is, it may be sixty, but it is wide enough at present, if it will only hold on as rich as it is at the present time, which seems to me near impossible. They have sunk OF the main vein workingI shaft which is eight and a half one way by four the other in the clear. ItI has two compartments and is calcu- lated for machinery. It is an excellent piece of work being we'll iimbered, &c. This shaft is now down no feetI and when they get down on the level of the 127 foot tunnel they will then drift southwest along the vein so as to connect with the tunnel from the incline to which I referred above, and which strikes the mother vein about 125 feet southwest from this main working shaft By this drift of 125l feet they will connect the tunnel and ore body with the main shaft, and thereby obtain ventilation which is very poor at present and which is an important item in regard to the sue cessful working of the mine They have also two other shafts down on the main vein to a considerable depth, one on the east end and the other on theI west, both of which have water in them.
 On the Hannibal they have a model working shaft down seventy-five feet, but are unable to work in it at present. on account of water until the arrival of the machinery which they are ey. pecting dally. When it arrives it will take about ten days to get it into posi- ton so as to pump the water out, and MT. Flournoy informed me that work
