WOMAN INVENTOR
 IS EAGERLY SOUGHT
(From Thursdav's Daily.l

IT MTS. OdIrle ENeTSOH, IS lN- ing, fortune awaits her, and if she has passed away, niche in the min ing nall of fame will symbolize her memory for all time.
 This woman is affectionately known throughout the mineral world as the "Mother of Flotation," and movement has been inaugurated by the Colorado Scientific Society to as certain where sine is. Many mining men of this section have been advised of the earnest desire to locate her, that either she or those of kindred blood may be the beneficiary of huge sum of money to be contributed voluntarily by those operators who nave prospered through her wonder ful invention.
 For several months the Colorado institution has been quietly carrying on a search for Mrs. Everson. and 1t being learned that she was known to have visited the Bradshaw mountain mines over a quarter of century ago, with her father, leads to follow ing the thread of where she had been or whither she was going when last heard of in this vicinity. Important facts regarding her career in Denver nave been brought to light, and 1t IS believed that very soon the mystery of the woman scientist will be clear ed away. She is known to have left Denver over thirty years ago with patents which were to make millions for other people, but were to bring her nothing.
 Wash Tub Discovery.
 In all the romantic history of min ing in the West, there is nothing more fascinating or interesting than that of the Denver nurse who while wash ing greasy ore sacks in tub at her brothers assay office, discovered the affinity of oil for gold and was clever enough to get out patents on her dis covery. Mining men, astounded at the results wrought through the tardy application of Mrs. Everson's won derful discovery, rank her with Madame Curie of radium fame, as scientist. Through Mrs. Everson's invention the small mining operator throughout the West faces a new era, and operators are astounded at what is being accomplished through fot- ation. Results are being secured which the theorists have declared i'm possible, and students Of metallurgi- cal problems are bending every ef- fort to find out more of the possi- bilities of the process which mas giv- en new aspect to gold mining every where.
 Litigation Ensues.
 With the disappearance of Mrs. Everson from her field of labor. and her whereabouts unknown, legal com plications have arisen that are being thresned out in the Supreme court of the United States, owing to Mrs. years ago. When the ffotation pro- cess was taken ID ana applied in this country in recent years the Minerals Company, of London, Eng land, brought suit against a Montana mining syndicate for alleged infringe ments of patents. Two courts have one finding for and the otn CT against the plaintiffs. It was con tended by the plaintiffs that the Ever son patents did not tell specifically how much oil to use in Notation. while the Mineral Separation Co.,, specified exactly the amount to use The court decided that the only difference was in point of degree and that any user would naturally use as little oil IS possible. The case has been taken to the United States Supreme court, where it now rests. Mining men all over the world are deeply interested in the outcome It is the claim that the Everson patents form the real basis of the process, and these patents having expired, make me discovery 1 public property Many variations Of the process are being used, but min | ing men agree that Mrs. Everson dis covered the three basic principles the use of oil, acid and air in com Jination.
 Acquainted With Inventor.
 J. P. Waldron, president of the Montezuma Mining Company, of the Bradshaw mountains, is personally ac- quaintcd with Mrs. Everson, and | stated yesterday she was a guest at his Colorado Springs, Colo, home, less than two years ago, since which time he has been unable to learn UT her whereabouts. She mentioned the fact of having visited the Bradshaws with her father, many years ago in a mineral research and to study the complex ores of that field. It was also stated yesterday by resident operator that Mrs. Everson passed away less than one and one-half years
