BABY RHNocERos BORN IN CAPTIVITY.

also a reverberatory, which will give the plant seven furnaces.
 About 900 of tons of Old Dominion ore and 120 to l30 tons of United Globe ore are now being daily treated at the shelter.
 Old Dominion flue dust losses must now be very heavy. One needs to wear automobile glasses travelling around the plant, as the dust, carrying heavy cop per values, fills the air.
 Until the plant is properly enlarged, copper costs will necessarily be heavy. The Phelps Dodge people have not the reputation of being low-eost producers. Their principal experience has been with the Copper Queen and it has not been necessary to cut corners very close with that property.
 Some idea of the size of the old Dominion proposition can be gained from the fact that 2,5O0 people are now on the company's pay roll, practically all engaged in mining operations, as comparatively few are required at the smclter or the mill. This shelter is probably the most economically run plant for its size in the United States. Not over dozen men are required to operate the four furnaces All the weighing of the ore, mixing and feed ing to the furnaces is done by four men, everything being automatic. It is q model of efficiency. No expense has been spared in construction. Dr. Rick etts has been criticized for extrava- gance in some quarters, but he has all ways been given free hand by the Phelps Dodge people and has never been obliged to eeonomize in any quarter All of the machinery is of the very best and he has never hesitated to throw old machinery on the scrapheap if he could secure increased efficiency by installing new.
 N. S. Berray, for fourteen years in charge of the Phelps Dodge interests in Globe, has had charge of all the Old Dominion underground developments since these interests came in control. He has, however, recently resigned to take effect October l, having earned competency.
 It was the opinion of the Bigelow management that the property bot toned on the 18th level. The formation there was shale and broken quartz with no evidence of copper. Former Superintendent Parnall, however, be- lieved that copper values would be found at depth and started to sink the Pld lnterloper shaft, then the only working shaft. He was down eighty feet below the 18th level in this shaft when the Boston office stopped further sinking. Recent developments, how ever, demonstrated that if Mir. Parnall had sunk 200 feet, or 120 feet further, he would have struck the rich ore body found on the 18th and 14th levels
 It is the belief of the Phelps Dodge that the ore found on these two lower levels is the apex of big rich ore body. The top of this ore body is rounded. The footwall has seventy feet dip, while the hanging wall is flat. tening, which would indicate that with | depth the ore body will be larger.
 Developments on the 14th level al- | ready show that the ore body is 300 feet long and 80 feet wide. This width was in No. 2 crosscut. In No. 3 cross. | cut the vein divided. When first cut there was 35 feet of ore averaging 10 per cent copper. Then "horsev was encountered which was 55 feet wide; i rich ore was again found, however, for 25 feet, then altered vein matter was again encountered. This was at first thought to be the hanging wall, but it IS now thought otherwise, and the cross gut will be continued with the expecta- ton of again running into rich ore.
 No. 4 crosscut recently encountered | the lode and the ore averaged 20 per cent copper where cut, instead of 10 per cent where Nos and 3 crosscuts first found it.
 A drift is now being run from No. 2 | ,rosscut to No. 4 along hanging wall of the vein to demonstrate it's width, but | Drihcipally to provide better ventilation. | The temperature on this 14th level is above 100 degrees and it is difficult to get men to work there.
 A winze is now being sunk to tho 10th level to determine the character of the ore there. It is expected that the sulphur contents will increase with iepth. The l4th level ore is sulphide. but not sufficiently high in sulphur to meet the company's requirements.
 It is expected, however, that within ! year the Old Dominion will be inde- pendent of outside camps for it's sul- phide requirements. The Continental mine is now supplying 1900 tons of nigh grade sulphido ore per month, and
