Their family consists of three sons and two daughters. In the spriug'of '92 he joined his elder brother at Livingston, and after building their present store put in a complete stock of general hardware, con sisting of tin and wooden ware, stoves and sporting goods, fishing tackle, guns, ammunition and traps. They also make a specialty of farm machinery of every description, including buggies, wagons, mow ers, binders, plows, harrows, seeders, drills, hay loaders, hay-stackers, wagon covers, and tents of every size and description. They have a full line of heavy and light harness, whips, cowboy and jockey saddles—in fact everything which goes to make a complete stock of hardware. The Nolan Brothers also make a specialty of furnishing complete outfits for tourists who visit the Yellowstone National Park. The first venture of this firm in the mining in terests of this region was in Cooke City, shipping several carloads of ore from the U. S. Treasury mine, but owing to the expensive operations of same dis posed of their interests there, and soon after set sev klipse'STAVES a RANGES %DS a & TENTS » , waoMMat jgpL- ^ -/ 'Or«« « « . • » < «8 ; V.,.

They are deeply interested in valuable prop erty at Aldridge, while their latest move has been in the development of one of the best propositions in Emigrant gulch. After their experience in the different mining sections of this region, the Nolan Brothers decided that the full value of the minerals and metals could not be obtained without the use of better mining machinery, consequently J. F. Nolan, in the fall of 1898, went on an extensive investigating tour to Den ver, Colorado, and other gold-milling centers, return ing with the following modern appliances for treat ing ore, and of which they are the sole retailers in this locality : The Elspass Improved Roller Quartz Mill, which is acknowledged by all mine and mill men who have seen it in operation, to be the best and most economical crushing roller-mill for fine pulver izing yet introduced, having a special merit for screening, bfrtli as to excellence of product and ca pacity; the Cammett concentrator, which is the most recently developed and scientifically designed concentrator on the market, having a capacity of from fifteen to thirty tons per day ; the Jackson Hand-power Rock drill, possessing elements of econ omy, simplicity, durability and efficiency, features ■ U ' P.

The excel lence of this process has caused it to be adopted wherever it has been properly treated. It is now used in the Homestake mills at Lead City, South Dakota, in Colorado, Utah and California and is being adopt ed in the richest known mining sections of Park county. In the different ores above mentioned it catches from thirty to one hundred per cent more gold than is caught by the ordinary plates—each having the same number of stamps and fed with the same ore. Wherever stamp mills have been operated owners have tried in vain to prevent the loss in val ues caused by the very fine gold floating on top of the slimes and from being carried over the amalgam plates and concentrating tables to the stream. It is to prevent this loss that the Eureka process is intend ed, and this is accomplished by injecting gas—the formula for manufacturing which is covered by fet ters, patent—into the pulp in the battery. The enect of the gas on the pulp is to dislodge minute globules of air that may adhere to the finer particles of gold, while the effect on the slime is to cut it as lye does grease. The result is that every particle of metal, no matter how small it may be, if it ha^e metallic weight, is precipitated so that it is brought in con tact with the amalgam plates and is there caught by the quicksilver, or passes on to and is served by the concentrator. Wliat is true of its action on gold is true of its action on silver, copper, lead, iron and all other metals.
