 The Union Gold Mining company has a nice exhibit of gold ore from the White Tank mountains.
 The Relief Gold Mining company has a very attractive exhibit of gold ore containing free gold. This is one of the producing gold mines of Mari copa county A claim the manage ment makes for it's bullion is inter esting. as it claims it is worth something over $2O an ounce, while pure gold is worth only $20.67
 Another exhibit is by J. c. Reed, which consists of ores rich in silver and gold.
 Mohave County-There is exhibited from Mohave county some very nice silver ores from the Treasure Hill mine, and also some nice specimens of hubernite. a form of tungsten ore, This mine, belongs to Dudeck. Sperl & Bondeack. This ore occurs in hydro mica schist.
 Graham county has good eX- hibit. but nothing new has been added this year.
 Pima county has added nothing new to her collection.
 Pinal county has added to her col lection by sending ores from the Calumet and Pinal Mining company, N. F. Gill, president. Another eX- hibit from this county that has at tracted some attention is an exhibit made by the Green River Copper Mining company from the Green River mine, in the Pioneer district, near the Lake Superior and Ari- zona's property. The ores are car bonate of copper. carrying gold and silver values. This is in the Pioneer district a district which is thought by mining men to be one of the coming copper districts of Pinal county.
 Yavapai county being a mining county has the finest exhibit of gold. silver and copper of any county in the territory A. A. Johns, the min ing commissioner from NaVapai county. is to be given credit for the interest and enthusiasm he takes in the Yavapai county exhibit. Johns is one of the most enthusiastic and earnest workers of any commissioner perhaps in the territory of Arizona, and the people of Yavapai county never make a mistake when they depend on him to advertise their in terests The largest exhibit is the United Verde Copper company's ores. This is a valuable exhibit to the mining men of any part of the world, as it gives a good example of the various forms that sulphide ores oc- cur in. as well as the altered and re- formed ores. With that exhibit this year are two beautiful copper bars that the public will ask many ques- tions about.
 Yuma county has added more ores to it's permanent exhibit than any other county in the territory this year. There has been received and placed on display an important showing of ores from the King of tant gold producing mines of Yuma county. This ore seems to be a quartz and a calcspar granite, asso- ciated with porphyry granite. The ore gangue is very similar to that found in the Mammoth mine at Gold field, Ariz It is not attractive and few prospectors would expect to find gold values in such an ore. The greater part of the exhibit from Yuma county comes from what is known as the "new copper country lying and adjacent to the A. & C. R. R., the towns in and near this district being Wenden, BOuse, Par ker. Quartzsite and others. No more beautiful and valuable or interesting exhibits of mineral are found in the mineral department than this ex- hibit of ores.
 No mining man can examine this exhibit without coming to the con- clusion that this new copper country is destined to be one of the great copper countries of Arizona. With these copper ores are also some very rich and valuable gold ores, some of the ores showing native gold. This exhibit of ore that is marked Yuma County New Copper Country" is the same ore that supplemented the Ya- vapai county ores that were shown at the national irrigation congress at Albuquerque, and above these ores hangs a beautiful banner on which is inscribed "Yavapai county. 1908, awarded first premium and $500 cash prize for mineral exhibit, Interna- tional Exhibition. First prize in gold, silver, copper. onyx, marble, mineral paint and lithographic stone"
