Letter From Powell.

statement of some of my observa- tions in the Chittina country.
 We leave the srhist formation of the coast range by crossing lime. stone contact at 6t; miles inland on the Governnen; trail. The schis of the coast range is auriferous. bi. S) far m pli., his been found where 1t is sufficiently concen ra- ted to pay. Poor Clark Moore worked for two years with hopes of finding pay on the eastern slope and it may some day he found.
 Some quicksilver deposits are found in the gravels of the lower Copper river, but not nearly so ex- tensive as in the upper valley.
 There is an anticlinal uphcaval extending along the western base of the Wrangel group, with a stiihC ioi IT aiiV soutn anu tHc sides dip about 8 degrees. The anticline is incomplete, as the top is disconnected, showing an up heaval from great depths. Owing to the great depth of this upheaval 1t Is not surprising that such cop per ores as are usually found at great depths are here found on the surface. The sides of this uphca- val are from four to six miles apar. and all the valuable copper finds are along its strike. Along this belt are great deposits of white limestone ant as it is followed nor. therly the lime becomes darker and in places, both b..cl and blue lines are found.
 It Is probable that the large cop per nugget found on Nugget creek settled out of the dark lime that crosses at that place.
 Lime dolomitc and carboniierous rock with incrustations of lime are also found along this belt.
 In the fall oi 'JS. in an article to my ho ne paper, proph. sled that the Chittina would surprise the world with is copper. That was based on Inc line powders found the variega,ed mineral ain and the native copper in possession of the indians.
 From the indications it is a won- der that erubescite, or silver with copper, has not been found and surely will during the next season. l am willing to hazard ano.her prophecy, and that is, those moun- ta!ns will some day be great silver producers. That is based on the extensive lime and porphyry con tac.s win immense sla.e deposits.
 From the great depths of this up heayal, and the carboniferous for nation, ii sandstone ;s found along it, We may expect good quality oi an. hraci. coal.
 From the tabulated or b.anke.e,l appearance of the country ie oi this an:iicii,;ie, it is safe to pre- dict that the Chittina valley will some day be in the cen:er of q great oil field.
 There is no asphaltum nor the carbonate of lime, known as chalk and it is probable that when o.l is found, it will be of parafi.ne base,
 The Chittina widely differs iron, the Alaskan range as the like for. Ina ioEs of the upper St.shi.n ma are on the fin, or jasper order and the coal IS he brown or Ignite char. acter.
 The gold, where it has been found m paying quantities, is on the yves, side of this great upheav. al, in block slate where are porphy- rite in;rusions. The east side Ina, not been prospected.
 This upheaval can be seen from the steamer decks on the way frOn Kayak to Yakutat, where it breaks out to the sea at Yakataga.
 The prospectors should consult together and exchange opinions O the different parts of the country have more camp talks.
