(In Mining and Engineering Worid)
 Oatman is experiencing a genuine mining boom. and many old timers from the early days of Cripple Creek. Tonopah and Goldfield mix there again together and with the throngs of the newcomers.
 In a way. the district is an old one. the Moss Mine in the northern part of the area having been discovered in 1863 or 1864. and a number of other properties having been located from time to time since then.
 The two main produce-s cr the dis trict. the Gold Road mine and the Tom Reed. were located in 1900. and have been worked continuously since. Both have their shafts 900 feet deep. with the ore going down deeper. and have explored the ledges for dis tances of several thousand feet on their strikes. The Gold Road has one continuous ore shO0t l-aU feet long. and has mined ore in quantities for a distance of 1000 feet on the vein. The Tom Reed mine has mined for similar distances.
 The Gold Road mill treats about VVNV NOA4N HtA AC saul tt average about $S or 80 The gross last production of the mine is esti- mated at over $6.000.000-
 The Tom Reed mill treats 1000 tons per month of quite high grade for mill ing ore. The value of the ore treated averages from $20 to $40 during the last few years.
 The total production to date exceeds S6.000.0O The cost of milling is be- tween $S and s9.
 Yet. what has attracted the atten- ton of the outside world has been the development last year of remarkable ore bodies in the United Eastern and Big Jim mines. below Outcrops which hardly show on the surface of the ground. Since then, development has been carried actively on a score of properties. and the results obtained have kept the enthusiasm and have increased the confidence ir the future of the district
 Peculiar Geological Conditions.
 Due to peculiar geological condi- ;ions. several ore bodies. which have proven of great value at depths rang ing from 200 10 500 feet. do not show up on the surface. and the veins them selves are quite inconspicuOus. This forces the mine operators to thorough, and. of course. rather expensive pros pecting by shaft sinking. to depth of several hundred feet before start ing any crOSscutting or drifting Net more than 100 companies have been formed: about 40 of them have start ed work or are carrying on actively extensive mining operations. and dozen of them have opened up bodies of milling grade ore.
 Oatman is no poor mans camp. on account of the expensive work re- quired for prospecting at depth. and because of the fact that. so far. the ore bodies when found have tO be mill ed on the ground. This calls for an other heavy outlay of capital Yet it must be said that the companies which have been operating have gone into the work in the right way. and that all the mining done is done through first class shafts. well timbered. with good headframes and equipped by modern and substantial plants of ma 
 Importance Of the Automobile.
 Here gasoline IS King All the pas senger travel is done by automobiles. Ever so often barker walks up and down the main street of Oatman call ing through the mesaphone "Passen- gers for automobile stage to Needles or passengers for automobile stage to Kingman." All the freight. but the heaviest is done by automobile trucks. which can carry 10000 pounds each trip.
 Only once in a great while a pros pector can be seen going out into the great hills walking behind two or Lhree packed burros reminders of an almost prehistoric age and who looks luite strange in the midst of his new 
 However. the heaviest freighting is tone by teams of or 10 mules. which have grown con,emptuous of the
