pyrite. The rock is often very white and hard and is called 

 quartz by some of the miners who are exploiting it. Three sam- 

 ples of this soda-feldspar dike from the Wheeler and Hill claim 

 were assayed with the following results :

The gold and silver and the iron pyrite appear to be dissem- 

 inated through the dike rock, for no little veinlets are to be noted 

 in the specimens assayed, as is the case in some of the miner- 

 alized soda-feldspar dikes. At the Black Warrior mine on the 

 Moccasin Creek dike there has been reported a valuable deposit 

 of workable ore since the date of my visit (1897). In the tunnel 

 of this mine a mineralized talc streak in serpentine contains 

 sulphides of iron and gold and silver. As to whether the valu- 

 able ore body is in the dike rock or not I have no reliable 

 information. 



Along Kanaka Creek about 2 km east of Jacksonville is 

 another soda-feldspar dike which is nearly in a line with that 

 east of Moccasin Creek. This is likewise mineralized at several 

 points. At the Willietta mine on the Kanaka Creek dike a con- 

 siderable mass of the dike rock has been quarried out and treated 

 as ore. This deposit was examined by a San Francisco mining 

 engineer, Mr. Luther Wagoner, and I am indebted to him for 

 the following information : About 3000 tons of the rock were 

 milled ; the top two or three feet of the dike yielding about $3 

 per ton. Subsequently Mr. Wagoner made a mill test of a face 

 fifteen feet high, this containing about 78 cents per ton in gold. 

 Another sample of thirty tons vielded 56 cents per ton in gold. 

 The concentrates (probably chiefly iron pyrite) were found to
