 FORM

Where claim owner has applied
 for patent, but at the time the money
 should be paid iDso the land office he
 decides not to make payment, the patent will not issue, but the claim owner will not lose his possessory title to the claim by reason of such failure, as he can continue to hold it as long as he complies with the laws govern ing unpatented cllims.
 In figuring of ores by assay, the commercial assa,r as ordinarily made is always meant, and not corrected as- says. If the value of shipment of where all losses by dusting, volatiliza- | ore is based cn 6 corrected assay. tion and absorption are taken into consideration, such computation will result in misunderstanding with the ore buyers. The buyers samples will not check with the sellers, and when the dispute is left to the umpire to make control as ;ays the umpire's as- says are more than likely to agree with those of tue buyer than with those of the seller.
 The cost of smelling can only he estimated, even approximately, when the character of the ore to be treated is known; the proper fluxes required, and their cost; the price of fuel and labor, both skilled and unskiueu, as well as size of plant. The region where enc smelting is to be done is an important factor. In som'i localities fuel is cheap, but fuxes are only obtainable at high cost, in others the fuxes are at hand, but all fuel has to be shipped in. The size of the furnaces is i'm pOrtant, as it is much cheaper to smelt in larger plant than in a small one. The cost of leading smelting under fa- vorable conditions ranges from $45O to $7 per ton, anl of copper from $3.5O to sS.
 The law recently passed by the Ore gon legislature 1T. regard to dynamite and other nitro powders, fuse, etc, is calculated to lessen the danger to miners who may be unfamiliar with the physical signs which indicate to the experienced and the observing the unftness of theIe materials for min ing use. Much powder used in mines is old, and has been subjected 70 a wide range of temperature which often makes it unfit for the best results in mining, beside making it dangerous to handle. The la,r requires that ali powder, fuse, etc, used in blasting operations, either shipped into Oregon or made in that state, shall have the date of manufacture stamped on She box and wrappers containing these ar ticles.
 All visitors from the Congress min ing section, including those who have recently been called there on business affairs, and who have no direct interest in that portion of the county, are unani- nous in declaring that the entire sec tion is in the initial stage of legiti- mate boom.
 It is announced that the Congress mine is steadily increasing it's force of men, and will in a short time have a new shift added to the payroll. There are now 40 pen under employment, and the better informed say that this force will be materially increased with in the netx thirty days.
 The White Gold Mining Company, which has been pushing development on its property east of Wiekenburg, recently sent to Prescott for more teams and teamsters, and is now pre- pairing to install 2O-stamp mill with a power plant large enough to permit of the addition of 20 stamps more should it be found advisable. This company is likewise putting in a cy- anide plant. and work throughout is being pushed with all possible rapid ity.
 The Octave people are beginning to haul oil for their plant, and develop ment work in new direction is re- ported as being under way. A tra- yelling salesman who takes much in- terest in the mining field of the county, yesterday confirmed the various re- ports concerning this district, and said that for two years past he has not 1 seen the country as wide awake and . busy as at this time.
