 As I may esibly send you an occaslon- al letter on mining matters, 1 offer at present slight sketch of the above DOT ,ion of our wide ie tritory, as that will, Tor d lime d; least, be the locality treated of in my correspondence.
 Unlike tue State of Nevada, with its north aud south mountain ranges stpa rated by valleys ten to fifteen miles wide, Southeastern Arizpna is greatly broken u,, by cross ranges and is.and-like hills, rising out of the oceany plains. The San Pedro River, it is true, tiuwing west of continuous range on each side; but on closer examination, long distarces are seen t0 he a mesa, or table country, not claiming any thing like mountain grand eur The Arivaipa Valley, lying fan ther east is for time more regularly walled jE, nu here, too, the ranges have breaks iu lncIn, one just north of Dos CabeZas Prahs, lo'mi;.g what is callrd Railroad p.,s catlse It seems tO have been open ed op 5urpCse 10 give the iron horse O. i.uy>.i and commerce an unim mpeded right ,l aa-.
 T1s Chrcahua Valley, running south .0m Dos CabeZl>. has the grand timber ta IL, intains of that name on its easterly >idr where for sixty miles the railroad builder between east and west is forced nv ccomcm;cal considera ions 70 turn as! Ie South of Camp Rucker in that range, and moi far from the Mexican front fer, d cross valley opens the way eastward inIo he San Simon Valley; but then to sci !lrther east with ease, a railroad con- ing through iL would have to run mortimer ly to a point nearly opposite Railroad Pass, which affords direct line between eastern and western passes. The only other op .nng for raiiroadng purposes is the Gila Valley. 5O miles to the north of Railroad Pass, and il Is locked with hills both above aud below, SD as to be almost impassabie.
 The Chir,t ah la Valley is not defred on the west by any long regular range. The DragOun Mountains intervene; but north and south of these the eye takes in only ruu Id topped hills, in valley settings, for 50 ur 40 miles.
 The climate is as nearly perfect as can be found anywhere. So eXacting do peo- pie hccumr, however, when they arc bless ed with 365 delightful days in each year, that they grurnblc bitterly when the fall and spring east winds bring, for two or three days at d time, q cold Atlantic-coast curr5nt to vitulize the heated westcrn af- mospl c.e. Between Christmas and the end of January, d few inches of snow fall and the sky is then dark and threa ,enlng indeed; but in three days.- tle sun in It's usual brightness makes an overcoat burden again. The hi hest summer lcm- pcratlre of the San Pedro and GIla valleys is about 105 Fahr. in the shade. On the shore of Lake Michigan, with its moist and stitling atmosphere, S5 deg. is far hot ter practically than 105 dcg. in the val | leys named. Our atmosphere IS so d'y, and evaporation so rapid, that perspira- tian is promoted. Sun-sirOke is never heard of, and men wearing black felt hats work hard beneath an unclouded sky and take three hearty meals per dsy. On the higher bottom lard, including the Arivai- pa and Chiricahia valleys, the thermome- ter rarely registers more than go deg, and the nights are generally cool enough to make blanket desirable as q covering. In this higher region, clIills and fever are unknown, and poor sickly-looking dys- pep,ics who arrived from the Atlantic toist speedily become well and vigorous For liver or lung complaints, there ca'' not be better climate; but sufferers must exert themselves on the mountain slopes, and not sit down, under the belief that they are too weak to take severe ex. crcise.
 A climate so desirable as we can boast oi here naturally makes good mine: more valuable than they would be if the coun try were in the embrace of frost and snow for third of the year. Fortunately, wt do not require to be content with yer, poor mines in order 70 eujJy a delightful
