The Tombstone epitaph., 1882-06-10
DENVER EXPOSITION,
Meeting at the Court House.
Address by Prof. Church.

oi propoSeu representation py Tombstone district at the Denver exposition. Professor Church called the meeting to order, and explained its object, read ing Governor Tritle's address on the subject. Judge P. T. Colby was elected permanent chairman, and C.. H. Howard secretary.
 The chairman introduced Prof. Church, who made an exhaustive ad- dress. He illustrated the importance of the exposition, it being the first ever held in America, to the mining industries of Arizona. It will be, he stated, really the first opportunity the Territory has ever had to adver- tise its mineral wealth. Should we stand aside and take no action we will assume responsibilities that will ever be regretted, and bring about a retrogration instead of advancement. The industry of mining IS the most important in Arizona. Copper and silver are the chief mineral produc- tions, and neither have received the attention they shoul. be given. De- velopments now made show great indications, especially in base silver ores, being for the most part sul- phurets. These ores need large expenditure of money in their reduc. ton and special treatment. The product of each district requires a special treatment of its own, and the needs of all are not understood in Arizona. Colorado has had more ex- perience in smelling than any other country in tho United States, and, therefore, the Denver Exposition will offer to the owners of such mines the best possible chance to show the value of their properties. Arizona has another advantage in the treat ment of base ores, in the fact that she possesses large and inexhaustlble beds of coal, which can furnish the best and cheapest fuel. We have gold ores, sulphuret and free, and carbonates and sulphurets of copper. At the Denver Exposition the charac. ter of our ores will be exhibited to those who are most familiar with their treatment, and who are eager for their acquisition. The professor went on to state that the Colo rado smelling works, although so ex. tenslve, find it difficult to procure ore sufficient to keep steadily run ming, and their proprietors would gladly reach out in the direction of this Territory were they assured of the character and extent of its miner. al resources. The smelting of iron ores is absorbing new capital every day, not onl-- in the development of mines but it the discovery and ap- plication of new methods of reduc- tien. The speaker announced that he had prepared circular for dis irritation throughout the Territory which contained the suggestion that the following ores, rocks and statis. tics form part of our exhibit: l. Free milling ores. 2-Base silver ores. 3-Oxidyzed copper ore. 4 Sulphureted copper ores. 5--Lead ores. 6-Lead ores with gold and silver. 7-Free gold ores. S-Sul- phurated gold ores. 9--In connec- tion with the proceeding, Iron ores and lime stones, suitable for fuxes. 10-Products of mills and reduction works. 11-Plans and models of mines. mills and chemical factories. 12-Clear and detailed descriptions of the methods adopted for treating ores, with plans of machinery. 13- Each district should send one suite of specimens of country rock, show ing the limestone shale quartz te or granite, and especially any eruptive rocks that occur in the district. 14-Statistios of ore mined, ore treated and bullion pro- duced since the beginning of mining operations, and especially for the time which has elapsed since the col. lection of the census statistics up to June 1st, 1882. In addition, the wood, water and agricultural re- sources of each district should be given; or, failing the existence of these, the usual source of supply should be stated. Governor Tritle makes the special request that all the geological and typographical features of the country should be mentioned
