The San Francisco call., 1898-01-02

Nevada County is taking hold of the mining exposition in d way that will enable it to make the most of the un- paralleled opportunity to advertise it's mineral resources. The committee has asked for 20OO square feet of space and will put in a magnificent and attractive exhibit.
 It will go further, however, and super intend its own exhibit. There will be constantly with the exhibit a competent miner and geologist familiar with every phase of the industry in the county, who will be ready to give any interested in- quirer practical or scientific information that may be wanted. This is an exam pie that every county should follow. Each county exhibit should have as great a display as possible of striking, curious and otherwise interesting things that will attract popular attention. A small pro- portion of the visitors to the fair will be wise about mining, but it is not chiefly to mining men that the exhibits should appeal. Thousands who know little or nothing about mining are investing in mines, or wanting to do so. The end to be reached is a popular understanding of the greatness and possibilities of the region. To ninety-nine out of hundred an immense block of low-grade ore will be more effective as an advertisement than a whole cabinet of small specimens that would interest mineralogist. Rel ics pictures, collections, maps, graphic illustrations of the total production of a county and some of it's great mines and so on will make such an exhibit center of attraction. complete and varied collection illustrating the county's re- sources to mining men, judicious descrip- tive information for distribution and an intelligent somebody to answer questions will help make up the most effective agency within the reach of any mining region to make known its wealth and hasten it's development. Hundreds of prospectors and thousands of investors and others will in the future turn thelr attention in new directions through what they learn during the five weeks of the mining fair.
 At this time the prospects are that at least seven or eight counties will make extensive and worthy mining displays, but there should be twenty of them. great exhibit from Nevada County IS as- sured, and most of the great mines Of Grass Valley and Nevada City are ar ranging to contribute ores. The Califor- nia Exploration Company is actively leading the enterprise in CalayeraS County, and with the cooperation of the miners generally, promises one of the most interesting displays that will be made At a meeting in Auburn to-mor- row the participation of Placer County will be considered, and the Supervisors will be asked to appropriate SSO0, The newspapers of SskiyOu County are wig orously agitating the proposition, and Siskiyou will probably be in line. In Plumas the Supervisors have been asked for $500 Amador Fl Dorado, Tuolumne, Kern Butte and Shasta promise exhibits, but the prospects are somewhat indeh- mite.
 There is gratifying and widespread inter est in the fair all over the State. but a little more vim and organization seems to be called for throughout the interior. A great many of the leading miners are making daily inquiry at headquarters and are cordially offering ores and col lections. Jefferson Dooittle of Gold Run offers to ship all the granite wanted for the hydraulic mining apparatus, and many of the leading mine-owners have offered large displays of rich ores if their safety is assured. Perfect arrangements have been made by Superintendent F.. H. Benjamin for the protection of all val uabie ores and nuggets, which will be constantly guarded and locked in safes at night There is no doubt that there will be a larger and richer collection of gold ores at the fair than was ever gath cred together at similar display.
 One of the important features of the fair will be a State miners day, with addresses by eminent mining men and others.
