The Tombstone Gold & Silver Milling & Mining Company, of which former Gov. A.P.K. Safford was president, in 1880 owned the original group of Schieffelin claims, of which the Tough Nut was the main property. A stamp mill was built on the San Pedro and a contract entered into with the Mormons to build a dam and ditch, from which it was hoped to secure motive power. Concerning this job, estimated to cost $6000, Merrill later wrote that the contractors found themselves fined $300 for six days' overtime on completion of the job. Joseph McRae's record tells that, in 1879, some of the brethren went up the river, twenty miles above St. David, and put in a rip-rap dam and a mile and a half of ditch at Charleston for the Boston Mining Company. This may have been the Boston & Arizona Smelting & Reduction Company, a Massachusetts corporation which had a twenty-stamp mill and a roasting furnace on the San Pedro, between Charleston and Contention, ten miles from Tombstone. This job returned $6000 in cash. The mines brought a relative degree of prosperity to the San Pedro settlement, furnishing a ready and profitable market for agricultural products, but especially calling upon all transportation facilities that could be afforded. Teams were busy hauling from the terminus of the railroad at Tucson and at Benson, until, in October, 1882, there was completion of the New Mexico and Arizona railroad, then a Santa Fe corporation, from Benson to Nogales, much of the way through the San Pedro Valley, past St. David and the milling towns. The mines paid $30 a cord for fuel wood and even $40 a ton for hay. Lean days descended upon the community, however, in the early summer of 1886, when the great pumps of the Grand Central mine were stopped by fire. The following year Tombstone practically was abandoned and the market it had afforded was lost. Not till 1901 did the camp revive. It closed again in June, 1903, by the drowning of the pumps. Latterly the old mines, consolidated, have been worked to some extent by the Phelps-Dodge Corporation, but again have been closed, early in April, 1921. Chapter Twenty-two On the Upper Gila Ancient Dwellers and Military Travelers Possibly as representative a region as is known in the settlement area of the Mormon people lies for about 25 miles along the Gila River in eastern Arizona, in Graham County, and within St. Joseph Stake. Over a dozen communities are contained within this section and all are distinctly Mormon in settlement and local operation, save Solomonville, at the upper end, and Safford, the county seat and principal town. Most of the land is owned by the Saints, who control, as well, a dozen small canals. Within the Stake have been included Mormon settlements of the San Pedro Valley and those upon the upper Gila, in Greenlee County, extending over into New Mexico and El Paso.
