EDITOR ENGINEERING AND MINING | JOURNAL: Sir; notice ill recent num- 1ers of the Journal paper on the | mInes or Tombstone, by Prof NV r. Raks. Inc authUr deals mostly with | the Contention, the Good Enough, and | the TouGbnut mines; and as the two | last mentioned mInes are in my charge, | l tremble lest those of my friends in the | Institute who know this fact should as sume that 1 accept the r of ssor's des- | cription as true.
 Although have been closely intimate | with every discovery and every opening m the loTghnut and Good Enough mines for the past year and q half, l can not recognize any significant fact set fortb iu the paper. Or course, one se- res of folded sedlmentary strata Is much like another, and the general aspects of Tombstone district are not different from those in other limestone regions i; but 1t IS just these general things that are of no importance, while there are individual characteristics Of each mine that are instructive and valUable|to the science of mining geology. It IS these useful particular facts that are entirely mIsrepresented in Professor Blake's paper.
 For instance, figure ,, page l57, of yOur issue pf March 2jth, represents q state Of things that does not exist in either the Good Enough or the Tough nut. There are vertical seams in our mines, as even a casual observer like Professor Blake could not fail to see; but they are connected with phenomena that he has not represented, and do not Occur as GguTe , shows. Figure IS equally at fault, enc of the controlling phenomena having been left out.
 The text Is as bad as the cuts, nearly the whole of the section headed "Bedded Ore Deposits being untrue or mIslead- ing. For instance the West Side vein Is not 1.-two miles long" and does not disappear unde- the granite Neither does IL cross the Good Enough, CT even appear at the open cut on the Tough nut. No ''s- cuud line of Assure" has been followed from tue open cut to the Way Up, and there IS no ore connection ln any shape OF form between these two points. No lode, pr any other form of ore-deposit, has ever been followed from the claim called the Defense across the Touyhnut into the Good Enough"
 
 assertion the author makes in the con cludinS section of his paper; but will leave matters Jf opinion alone. The things 1 have brought up I deny, not on the grounds of opinion merely, but be- cause the whole area described has been thoroughly opened underg ound and repeatedly examined on the surface, and | nothing of the kind was discovered.
 The truth |, Professor Blake gained ! what observation he has of the mines in l question while engaged against their l owners in mining lawsuit, and he has | thrown into his paper the points which | his side desired to make. Aside from | the recklessuess which would present | the prejudices of a controversy as scien- | ilfic facts, there can be no doubt of the ! of publishing a paper such | uS tbis before the controversy in ques- tinn has been judicially decid q. I do not believ the Council would allow the | Institute to be made the medium of an ttempt to improperly i.huence the | court, If they had known the circum- ,tances under which the paper was pre- pared. ] am, very truly yours,
