Here is another repetition of the daily tale attending California mining and the faith and enterprise of men who go De- low the surface to find out what there may be there. The Grass Valley Union says:
 'The well-known Gold Flat mine, which of late has been called the Unity, is un- der new management now. The ten miners who have been operating 1t for a year past yesterday relinquished their bond on the mine, and it reverted to the owners, Messrs. Weissbein Brothers of Grass Valley. It is understood that the miners were well paid for giving up the property, which has been developed and put on a paying basis by them. At the time when they took hold o. 1t there was nothing in sight, but by practical and co cred and some excellent ore has been extracted. The shaft is down to depth of about 3ov feet. The new operators have already put crew of men to work, and will develop the mine thoroughly, and in time 1t will doubtless prove dividend payer"
 Anything in the line of cheaper pro- cesses or those adapted to ores which have defied the processes heretofore in use is watched with great interest by mining men. In Montana Alderson, who has long expermented with the cyanide process fin that field, has been developing an original treatment for certain refrac- tory ores, and the status and promise of ms work IS thus described by the West ern Mining World:
 He is at present experimenting with the tailings of the Southern Cross mine This mine has long remained idle on ac- count of the intensely refractory charac- ter Of its ores. Thousands upon thousands of dollars have been expended in the past In an effort to devise some method of treatment by which the values could be successfully and economically extract ed. Experts from various parts of the ,rnh lon, and been compelled to give 1t up The mine. with its wealth of ore bodies, was closed down. 1t being impossible to realize enough values from the ores to pay the expenses of working the property. MT Alderson recently grappled with the diffi- culty, and has at last succeeded in over coming 1t by chemical processes known only. to himself. He has discovered that in the original treatment of the ore less than 70 per cent of the values were saved From ninety-seven tons of tailings so far treated he has obtained over $500 MT. Alderson's successes mean a great deal to the future of the State. It vii De only question of time when his leach. ing plants will be adapted to the treat ment Of refractory ores all over the coun try, and almost revolutionize mining ir that thousands of abandoned properties Will quickly respond to the new order o1 things and take their place among the rich producers of the northwest"
