SOME VALUABLE DEPOSITS OF
 BARYTES

PHOENIX, Aug. 26.-Arizona's rep utation for large deposits of mineral is certain. There Is no doubt but that in this Territory there are prob ably larger deposits of copper and the precious metals than are to be found in any other states in the union or in many other entire na- tions. However, there are many en- gagged in a search for the rarer min erals who hope to add luster to the already great fame of the Territory as a place most favored by nature. Reports have been numerous of the discoveries of platinum and cobalt and of hicl5sl and although these metals have never been found in such quantity as would warrant develop meent, yet there is constant search for them and for other metals not usually sought by the ordinary pros pector.
 Although in no sense a precious mineral deposit there are several lodges of barytes or barium sulphate in this county which. if developed. migh. prove valuable and be the basis of founding some small manu- factories when the power from the Roosevelt dam is available. The barytes in this section is of good quality and although there Is a small component of iron in the samples tested, yet the proportion of the iron Is not sufficient to render the heavy spar without value for commercial purposes. Several miles east of Mesa and reached by good wagon road is ledge of the spar about a mile ;n length and varying from twelve to thirty feet in width. This ledge has been located by Mesa people for couple of years and although the
 price which can now be secured for
 the produce is not sufficient to war. rant it's mining it is being held in the
 hope of an advance or the probability Of some local industry being estab ,ished which may have some use for the barytes. A shaft of forty feet has been sunk in the ledge and fl has been found that the iron com ponent becomes less with depth and the value of the spar consequently increases.
 Barytes is found native in England and in some places in Europe. The present supply in the United States l. mined or duarried in the states ol Missouri. Tennessee, North Caro- Hna and Virginia and the average value of the product. which, however varies widely in grade. Is a Httls lover 8 a. ton. By being utilized fl proper industries the best grades can
 be made to yield a much larger re
 turn than the average price.
 The spar finds many uses. The finest grades are employed in the Esnufacture of delicate pigments i'arium sulphate Of good quality is E-ed as a substitute or an adulter. ant for white lead in making the tcdy for paints. Many of the besr
 chemists contend that the barytes stouid cot be classed as a adulterant, ss 1t is superior as a paint body to
 hite lead and where 1t is used fin C. junction with the lead it makes |. I oh finer grade of paint that if the tarytes were not placed in the com pound. Some of the spar finds use in the manufacture of reagents and iu lyroteciInics. A course grade is used on the canvas covers in which hams are placed for shipment.
 Another use not common now, but which was once in general practice was fin the making of the higher grades of pottery. For this purpose the material finds its highest value. In the eighteenth century the barytes was used in the making of the fam
