A correspondent, writing from Sonora, says the sale of the Trinidad mine to an English Company was one of the most dis gracefully handled affairs which has ever afflicted Sonora While considerable money was really invested in the mine, machinery and buildings, 1t was generally done with heavy commissions to the man agers, but on all work done in Sonora roads. buildings and operations of all kinds, it degenerated to a regular steal, with no practical efforts to work the mines or to make the business a paying one. As evidence of this the Trinidad mine worked and reduced on the Mexican plan, has produced over $l00000 in the past four months, of which half Is profit, and with the means and capital of the English company 1t should have done twice as well at least Scarcely any attempt was made to work the mines at San Javler and Los Bronces, more of less of the ma chinery at Los Bronces being torn out and carried away. presumably to La Trim idad.
 At San Javier a ten stamp concentra- ton mill, quite complete was erected but only partially paid for, and seized by the creditors, and Is still standing idle The difficulty with this and most of the Eng fish companies Is that they are loaded down with unnecessary and nonproduc- ing officers, often entirely ignorant of the business and almost always ready to take advantage of any opportunity that may offer itself to better themselves at the expense of the Company.
 At La Baranca in the Hermosillo dis trict are located the reduction works of the Graf Company under charge of Don Luis Gonzales carefully managed and paying concern for many years. The mine Is at Tahumard, three miles east and ore Is brought over on burros and mules, though there IS steep wagon road. There Is also another mine and mill in La Barranca- BelOn, which has been worked for many years by Don Francisco Flores, and has always paid good dividends.
 The concentration works at La Dura ill HemosilIo district are among the best on the ointment, built in Germany and capable of handling 30 to 40 tons per day. The La Dura mine Is still paying more than expenses, but the vein is said to be lost The big paying mines at present are the Minas Prietas, some two miles from the works. It was worked by the Spaniards a century ago, and abandoned tlltu 6Itiitt D0OdlloC VT iOO AhtNI ndbCi Ol because they were driven out of the coun- try Some 10 years ago San Francisco parties spent considerable money and time to find the ore, and finally abandon ed it again. Then in 1887 the present parties took hold of it, and in few days struck the vein, and it has paid largely ever since. The trouble in finding the vein was on account of the faults. The J;p cf 4ba vrain in all tha different nartS of the mine is to the northwest, and Is in terraces, each terrace to the west having sunk away from the one on the east from 20 to 100 feet, of course carrying the vein along with it. So far, four terraces are found, and there may be more. Work is being pushed and over S7O0,0OO so far taken out, and the prospect still good. The greatest depth yet reached is about 300 feet The ore consists of gray copper, some lead, but with scarcely any deleter- ious materials Part is shipped as it comes out, and part IS concentrated | Minero Mexicano.
