 is near the summit of a mountain
 about 4, 400 feet above the sea level
 and 200 feet above the canyon. Tho
 ledge is shown on both sides of the
 mountain, and at the bottom of the canyon to the northeast where it is di
 vided, although losing none of its di mansions. Just below the slope to the east of the summit they are driv. ing a tunnel, expecting to strike the vein about 65 feet below the surface, The work proceeds slowly owing to the lack of capital Specimens of very rich mineral have been taken out; those which I brought with me are second class, but appear to be of chloride nature, very easily worked by mills. The average pay of the entire width of the vein is $100 to the ton. A half mile to the southeast of this camp are the celebrated placers. They are on the northerly slope of a ridge running almost east and west, This place is noted for enormous masses of hard porphyry which ex- tend southerly from the top to the bottom of the slope. Be low one of these large masses which occupy the crest of the summit, is where they found the large strip of silver in 1769, weighing $500 DO nds but lately the remains of the forges could be seen which were used in re- ducing this mass to portable sizes. The appearance of the ground is that of common earth, gravelly and con glomerate, and in parts dccomposed. These 300 square feet h we been pros pected to depth of over 20 feet, but in the time that has elapsed have be- come covered with tllickeis and trees. It is calculated that from this placo to date, there had been taken DO less than 40 tons of native silver in balls, grains and strips. The largest ball found Tn more recent times is that of General Serna in 1871, weighing 45 pounds which am told is still in his possession From time to time when there has been water in this small canyon, they have taken out grains of silver. I heard of some in the pos session of Mexicans at the camp weighing from one to two pounds but did not see them. I however succeeded in obtaining some speci mems which were taken from this canyon. They have never found sil- yer even in the minutest quantity on the southern slope of this ridge. The only sttempt to find the source of these extraordinary deposits of placer silver has been superficial cut at the top of the ridge made, am told by Gen. Serna, but only to the depth of ten feet. Several months ago the Americans working 6 La nina de los Pobrcs,'' commenced running atm uel at the foot of these placers with the intention of penetrating the mountain to depth of 100 feet. They are in about 30 feet entirely in ''cal ishe" gravel and cement, ledge of which appears to traverse the noun tain ridges at right angles, another notable feature of these placcrs. One hundred feet to the southeast of the | excavation, where they took the large | mass of silver, they have made cut in the hill, which reveals well de fined ledge three feet wide contain ing ore similar to that of the "Hilo." The course of this vein has been carefully traced to this point, and no doubt exists in my mind that this is
 
 the original source of all the silver which has here been found in it's na- tive state. A section of this ledge in the Planchas and run hing up to the Hilo has been de 
 THE DISTRICT
 Is favorably located for economical The climate is delightful all the year round. Of water, pas turage and wood there is an abund-- ance Roads of easy grades can be found without much trouble. Labor and provisions have always been ob- tained from Sonora at small cost, and the proximity to the frontier of the United States, offers sufficient guarantee for. protection.
 In my opinion the district recon mends itself favorably for the invest ment of capital.to develop its natural resources.
