of the National Mining Exploration company will cut the Black Hawk vein now developed in Arizona Commercial ground at depth of about 600 feet, which means sinking about l50 feet further, says the Boston News Bureau. There is no reason why the National Mining company should not cut the Black Hawk vein where it is now sink. ing. The Williams shaft is 800 feet west of the end line of the Free Amer. ica claim owned b ythe National or about 1000 feet from the Eureka shaft of the AriZona-C Commercial.
 After value is proven at depth in the National company s ground, there will arise the question between the Com. mercial and the NationaI companies as to who is entitled to mine the Black Hawk vein within the Free America claim of the National company, whose shaft is 450 feet north of it's south side line. The Arizona Commercial not only has three or more claims to the west of the seven claims of the National company, but surrounds on the three sides the Free America claim of the National company in which claim is now the Nationals man expenditure.
 The mining engineer, Edwin C.. Chase, reported November 10, 1908, to Messrs. Gay X Sturgis, and from the first page of his report as now on file with the National Mining & Explora- ton company we have been courteously permitted to copy as follows by the of fcials of the National company:
 "The Free America claim, it is true. adds 1900 feet additional length, but has no special value that l can see at present for the reason that the two veins apeXing within the Arizona Com mercial s Matamora (north) and Omega (south) claims would have the legal r ght to follow the said veins on their dip underneath the Free America claim and to extract any ore therefrom. How ever. 20O0 feet is amply sufficient ter rtory from which to make mine if the ground carries pay ore.
 It should he explained in relation to the above that most of the l07 acres of ground here owned by the National com. pany and bounded east and west by the IF acres of the Arizona Commercial company cross the mineral formations at Globe, Arizona, north and south, and command this mineral formation for about 2,0O0 feet east and west, the Free America claim projecting an ad. ditional 1900 feet eastward. and to the boundaries east. north and south of the Arizona Commercial property.
 The Black Hawk lode outcrops in an l. Al Al t ;. corner of the Arizona Commercial property and dips to the north This was very rich ore and paid for sinking the Arizona Commercial s first shaft known as the Black Hawk on the dip of this vein. The outcrop ol this vein can also be followed on the surface wester. ly to within 300 or 400 feet of the west end line of the Omega, where it dis appears into the earth.
 Ii should dip to the north under the ground of the Free America claim of the National company. Of course therefore, the Arizona Commercial com pany must enjoin the National company from taking any value from the Black Hawk vein as soon as it could prove that the Omega claim is entitled to fol low this vein under the Free America claim of the National.
 The Arizona Commercial company s big working shaft was put down to the northwest of its first shaft and inter eepted the Black Hawk vein on the dip. and it is now about to open the sev. enth level on this vein rom it's vertical shat.
 The National people admit that they abandoned the Iron Cap shaft west on their property and located the Williams shaft in their ground near the Arizona Commercial shaft because o. the Ari zona Commercial s better showing. The Arizona commercial people said it was foolish for the National company to put down a shaft in that location, be. cause if they reached the Black Hawk vein. the National company might not be able to hold title to it. However, if the National company wished to ex. plore thIs ground, it was so much to the advantage of the Arizona Commercial company in every way that friends ot the Arizona Commerc. al company were willing to advance $l00,0O0 for this de velopment and hold the mortgage on the National company property.
 The National company people, how ever, are willinp to take their chances not only of reaching the Black Hawl vein at this point, but of finding ore m it several hundred feet west of the Arr zona Commercials development, and also of being able to meet the apex claim that the Arizona Commercial company should aset up after value is found
 If value is not found, the National company's shaft might ultimately be used to ventilate the Arizona Commer eial ground. At present, however, the Superior Boston workings to the east are connected with the underground workings of the Arizona Commercial.
 The National people declare that the Black Hawk vein is now more vertical at depth than as originally opened, and therefore may to the westward anev wholly within their clam. They also claim that the vein apexes 300 feet un. derground in their Free America claim and say this is indicated by the devel- opment in the Arizona Commercial company's Eureka shaft and by the de- velOpments which they themselves have made to the west of their property where the National company claims to have found the identical Black Hawk
