iron and manganese and low in sil- lea. So far the main body, the ia nous 27 crosscut, 1900 level, is in 25O feet of practically solid ore and 150 more that can be stopped vita an ay- craze of about 8 per cent. It runs all the way from four to 305, is cross cutted only in two places. one l20 feet wide and the other 70 feet. It is raised in one place solid 50 Feet and 40 feet more was stoping ground. This is as far as 1t has been develop ed so far. In the northeast corner of Delnorte claim sulphide ore in one stope, averaging 10 per cent copper. cut in one direction loo feet and vert ically 90 feet, but had not been cross cutted. Sufficient time has not elapsed to determine the extent of the ore bodies between tine HOO and 1000 feet levels, but several stopes have been opened up and shipments made. On the east side of the claim Is an oxide stope. running about 10 percent and northeast is a stope of sulphide. running about per cent. The shaft alignment is perfect, one of the men in charge. Tere is 800 certainly speaks well for the ability of the ment in charge. There is 800 feet of leached ground on the Del norte claim going towards the Briggs shaft which will average 1-2 per cent and some 75 feet of it averages better than per cent. The 1900 foot level should develop more on account of the great amount Of leach- ed material in the levels above. In fact a large portion of the i2O0 is mineralized, that is it carries iron and copper values At the same stage the Irish Mag did not show up as well as does the Hoatson and no other mine in the camp has developed as much ore as the Hoatson the past two months in the same length of time.
 Junction Shaft.
 The Junction ships 150 tons daily and is Accompaniment shaft, down 400 feet. The deepest level is the 1900 feet, but they will very soon start drifting on the l400-foot level. So Tar four orep bodies have develop ed, one on the 770-foot level. averag- ing 10 per cent, 50 by AS, oxide; two on the 900-foct level, the first, 75 by 30 by 75 oxide, 12 per cent. and the second 75 by 100 by 50. oxide, ' per cent; and one on the 1900. sulphide, averaging s per cent. 40 by by 325,
 Work is continuing on these bodies and they are developing larger daily. The 1300-foot level has been but very little developed but what it has has shown very promising leaehed lime and iron, which is a sign in this camp of ore in lower depths. The 1300-foot level Of the Junction is equal to the 900foot lever of the Mag and 1t can be readily seen that depth is necessary as the Mag's principal workings are on the 1050 and 1150-foot levels. The great drawback to the properties in this section is the water problem. While it is well under control at the mo ment it has been a big handicap and only those who have closely followed the working cut of this great proper ty CS. & P.) can realize what the management has had to contend with. In sinking the Junction aIu Hoatson it was absolutely necessary for the men to work in water up to their waists and pumps going full blast Even a stop of a few minutes oy the pumps would throw them back hours. A look at tine battery of boil CTS at the Junction will tend to car " out this statement.
 Cole Shaft.
 The Cole shaft is a four-compart- ment shaft, 400 feet deep, connected with the Congdon and Oliver shafts, on the S50-foot level Of the Cole which is equivalent to 1250 in the Congdon. and on the 1000 of the Cole which is equivalent to HOO in the Oliver. They are shipping about $50 tons daily. Forty per cent of the ship ments are coming from the Sunny side claim of the P. & D. The other most important shipping is from the South Bisbee claim. Ore has been developed also on the Jessie, Glen cairn, and Supplement, and three months ago the Disowned claim op- ened up an oxide body for 60 feet. running per cent.
 There is one large body of ore ua the Sunnyside claim which has occa- sional barren spots. Roughly it is 400 by 400 by 250. There is consider able very high grade oxide in this, but mostly low grade sulphide rum ing about , per cent. but an excellent fiux. The South Bisbee claim has ore developed for a space of roughly about l50 by 15O by 250 This is not solid, having several barren quo leached places, but considerable stoping ground. They have been shipping from this body for two and years. It runs to , per cent oxide. On the Election claim ore has been developed 125 by 150 by 60 oxide nalachite and carbonate with an average of 10 per cent. There was also a recent find on the Supple .ment claim, 100 feet of oxide run ming 6 per cent. There are several other minor stopes and drifts but, in comparison. these are small. There is more ore blocked out in the Cole shaft territory than ever before.
 The work on the S. & P has been more concentrated on the develop ment work on the Hoatson and June ton. It is expected that especially good ground will be found adjoining the Shattuck
 American Development.
 The American Development shaft is down about HOO feet and connect ed with the Denn. TAey are waiting for the s. & P. to lower the water. This is also what the Denn Is wait ing For. Both are promising proper ties.
