Special Correspondence) JEROME, Ariz.. June 27.-The Jerome camp seems to again be com ing into the limeIignt, for in the past week or ten days three of the active prospects-Verde Combination, Pitts burg Jerome and Calumet and Jerome, have exposed favorable conditions in the work being done in their respec- tive properties. The foregoing, to- gether with the anticipated starting up Of the new shelter of the United Verde Extension and the prospect that Jerome Verde will begin the extraction Of ore from the Maintop claim, all tend to create the same degree of ac- tivity and excitement that prevailed during the boom days of the fall of 1916. Now, however, it is not due to stock gambling and blind speculation but is the outcome of carefully fol- lowing anC keeping track of the exten- sive and systematic development work which has been carried on at the ac- tive properties during the past year and half
 Verde Combination
 This property is exposing condi- tions which at present are more favor able than at any time in its history, and, to say that it's the most promis- ing prospect in the district today, is merely giving Combination its just dues.
 The work of cutting the station brought to light many stringers of extremely heavy chalcopyrite, sam pies of which assayed Is, 20, and g per cent in copper to the ton. When it is taken into consideration that pure chalcopyrite runs only 3412 per cent to the ton, the high quality of the ore being taken from these stringers or feeders can be realized.
 The mineralized stringers occur in both the east and west ends of the station, however, the west end is by far the better showing of the two, the schist here being muchly sheared and the stringers larger.
 That the naturalization, which dips downward and toward the northeast, has its origin in the quartz ledge (No. ] 13) exposed on the 700 level, seems to be a near certainty, for at one par ticular place in No. 13 some chal- copyrite was encountered which is similar to that found on the lower level.
 While the finding of a permanent and large body of ore is still a gamble, ] local investors feel so confident of the ultimate success of the property that they have been consistent purchasers of the stock since the recent showing was exposed.
 Jerome Verde
 On the Maintop claim the station m the raise which is being run from the HOO to the 900 level has been cut and ! they are now timbering the same. In the bottom of the station the forma- tion, which is a broken up and much oxidized quartz-porphyry and schist, contained some speckd of native cop per.
 In the same country the 1100-1S drift following the contact has been advancing rather slowly on account of bad ground necessitating timbering. The benching-off of the headings to make an even grade for the connection with the Columbia shaft is proceed i ing satisfactorily and the work should be completed by the time the raise is finished.
 In the Columbia shaft side of the property only one heading is being run, the 110O-22, which runs north erly from the Northeast drift to cut the pyritic zone exposed by Diamond Drill Hole No. p. Work in this head ing has been rather slow, due to the hard, tight djorite which has lately | been encountered.
 | Diamond Drill Hole No. g, which was run from a point 300 feet east of No. p, has been finished having penetrated a distance of 700 feet. The formation for the most part was greensboro and diorite, although cuartz-porphyry was cut at about 200 feet. A new set-up will be made in the north drift 300 feet north of the ] crosscut which makes the direct con- nection between the Columbia shaft and the Edith shaft of the United Verde Extension. This bore will be run easterly to prospect the territory to the north of the point where the pyritic zone was cut by Nos. 20 and 22.
 United Verde Extension Shelter
 General Manager George Kingdom has announced that there will be no demonstration of any sort attending the blowing in of the blast furnace of the United Verde Extension smell ter. In fact he said, that although he
