In my last letter I wrote Of the forma ton of the earth beng impregnated with water, which by the pressure of the ground and .he change of the tempera- ture produces vapors of acid.
 These acids are produced from the different formations of the ground, and also from the roots of plants or vegeta- bles, not only the plant when in full life, also when broken down and de ceased by the everything destroying moisture of the atmosphere; by the great process of the work of nature, nothing is lost, the destruction of one body IS the material of construction to n new body. It would be out of place to go into the details of botany, but III q future letter I will prove that pants. trees and vegetables are the original oi coal and carbon. In this letter maIu- ly wish to explain one of the greates deriving articles to the poor prOspectOf. the vegetable stain. The growth Ui vegetables is different and according to the climate and mostl! according to Ihe altitude and formation of tue ground; the true companion of the DrOspt ctor fUI gold Is the pine tree, and for silver Is sage brush,the chapparal cactus and the chayOyer.
 have seen where prospectors have dug fifteen to twenty feet deep on 8 lode of spar, being n lime which was lmpregnated with a greenlsh color anu spriukled with black dots. The men have worked for months on this wonder full rich strike, and too far of from any place to get the stuff asseyed, and witt the good will of a brave man-wh;ct every real prospector IS who leaves hls home and comfort tu trial against the elements of nature who for days goes without a mOrsel to FBt or drink, or tO battle against the wild beasts or the fiendish and brutal attacks of tue Iu dlans is through his eff rts to enrich the treasure of the country, then the prospectors are the only men who al ways produce, even II they do not find anything of value, the proof Of their labor that there IS nothing of any value when at last, and to theIr sorrow, they find that by an analysis of their rich ore their hard labor had been for noth- ing, as the expected mineral stain has proved 10 be nothing but vegetable stain.
 This could be easily avoided by every prospector carrying with hIm some glass tubes, a small bottel Of nitric acid and a small bottle of ammonia; the latter, no man ought to be without iu the mountains, where there are rattle snakes, scorpions, tarantulas, etc, gs it IS the best medicine U wash the wounds infIctei by said animals. Take a piece Of the ore and pnlverize the same; take an empty cartridge of a re- vnlver, i'll the same, and throw that amount in glass tube filled ihree-quar- ters full of nitric acid; then hold the tube over cinder or cand until the same bOi,s, when the sulphurets will form black sediment at tue bottom; the clay, lime or other formations will be above that,and between both, If any silver is ID the same will show in whitish layer: the whole has been cooled, take s few drops of ammonia and if there is any copper in the ore, the copper will pro duce blue fluid On She top of the glass tube; then take the whole and wash thc game through piece of plotting paper, by which you will save the sulphurets, if there be any.
