MINERAL EXHIBIT IS SMALL BUT
 CLASSY

hibits at Fl 'Paso fair are rather lin- ited in quantity and in the number of m ming districts represented; but the few represented make up in quality There are exhibited such rare miner als are cinnabar and tin, which are actually being mined in section trib- utary to Fl Paso. These are Texas products ahd she stands without li- val save California, in producing these two minerals.
 The exhibits of minerals are from the Swisshelm mountains, Arizona, LofdsbUrg, New Mexico; Mount Franklin, Fl Paso; shafter, PresidIo County. Texas; Alpine and TerIingua, Brewster county, Texas; models OF concrete illustIations Of specialization or crystal types, made by J. c. Critch. ett, mining engineer and chemist. of Fl Paso.
 This is the result of scientificc ,n- vestigation, following the indHctive method carried on by Mir. CritcneJt for, F years and illustrates the wonderful laws of nature in building up mineral crystals. Lordsburg Exhibit. The Lardsburg, N. NJ, mineral ex- hibit represents the Superior mine with ores of gold, silver and copper; the Bonney mine, with ores of silver gold and copper; the Miser's Chest, with ores of gold, silver and copper
 These mines are all in active opera tion and shipping ores at a great prof it to the smelters at Douglas, Ariz. The Superior mine is owned by Fl Paso people and has over 2000 feet of development work and record of having produced over S250OOO. The Miser's Chest is owned by east Texas people, and the Bonney by an eastern company. Col Peter Wehner is in charge of the exhibit
 One of the striking features of tho Lordsburg mineral exhibit is the beau tiful character of the ore, it having the yariegsted colors of the rainbow ore being an irridescent chalcopyrite. For this reason the ores make very showy specimens that would be an adornment to any cabinet . .. SwissheIm Mountain Ores. The Swisshelm mountains, Arizona, are represented by mineral samples from the mines of the Heffern mining and development company and consist of ores assaying from three to 12 per cent copper and S2 to s6 in gold and silver. The ores on exhibition ap- peared to be oxidized.
 This property has shaft 800 fe 4: deep, timbered and lined and drift and crosscut running on the 400 level No. 1 crosscut is in 165 feet and No drift is in 159 feet The shaft is sunk in lime formation between CIVIC andesite porphyry dikes. These dikes are said to carry from S2 to S66 gold and also silver and constitute milling ore.
 The property is equipped with 45 en
 zine hoist and S5 horse power boiler
 In addition to these ores there were
 samples of hone stone or nayacaliL&
 and a beautiful large speciment O
 crystalized calcite, weighing 15(
 pounds; also samples of iron ochre O.
 mineral paint and tuffa building stone.
 , Albert Heffern, of Bisbee, Arizona president of the company, is in charg, of the exhibit and is a mining geolo
 gist. In addition to the mineral ex hibit is a remarkable display of aGri cultural products raised by the dr! farming method in the neighborhoo, of the camp in the Sulphur Spring
 valley, and a fine collection Of pani ramic views of the mines and farm ing lands.
 Tin Ore From Near City.
 The Mount Franklin tin mines 0
 Fl Paso county, Tex, which are 10 O l2 miles north of this city are reprt scnted in collection of two or thre
 large samples. One is a quartz throug . which the oxide of tin or cassiterite I :, disseminated of remarkable richnes! - epd an other large sample is of graI ite impregnated with cassiterite whic has received the local name of "cas' granite.'
 Tn this, granite, the usual const!t, LII ent. mica, is. absent or nearly so, an E it's Llace filled with cassiterite. I'll h mass is composed of orthaclase an J. quartz. There is said to be in the Ii
