Prof Blandy Of Prescott Tells or
 Their Wonderful Possibilities.
 Prescott, Oct. m.-(Special cores pondence of The Republican, n.)-At the request of several persons, who are interested in the working of placer grounds, there was test run made, on the 4th of September of the "Gra- vel washing and lgamating ma chine' designed an f1ilt by Thom- as G. Barlow-Massio Hat the diggings on Lynx creek, about eight miles east of Prescott It should hardly called a test rum DJt rather an exhibition, as the machine\ bad been running several months in she early part of ~r the year.
 The result was seventy -tw0\ cubic yards of earth, dug and washed,>In forty-nine minutes; equal to 8S 1-6- cubic yards in an hour. The clean up from the first plate (there being six in alp was s15.55 or 21.6 cents per cubic yard. Within the forty-nine minutes the whole machine was ad- vanced on the track five feet; this being necessary to show the readi- ness with which the whole operation of moving forward as well as the dig gfng could be done. There are six men and two boys employed to take care of the various parts, including one man to run the steam pump to deliver water to the machine from the settling pond.
 Last winter and spring this ma chine had a fair test side by side with Little Giant with a four inch nozzle under head of 270 feet The gravel banks are ten to twenty feet deep, the deepest part being worked by the Giant stream The expenses of the two operations were about the same, but the clean-ups showed much in favor of the ma chine
 It will be understood that where a sufficient amount of water can be had, under. a head thai will deliver it into the machine, the expense of pumping is saved, but where the SUD- ply is limited the water runs back from the machine to a settling pond and is used over again
 In a circular issued by MT. Barlow Massicks he says "six hundred gal Ions of water per minute is pumped through the machine, but the bulk of this finds it's way back to the settling pond, and it has been ascertained that constant supply of S0,OO0 gal Ions per twenty-four hours will run a 600-yard machine for twenty hours.''
 Again, he says ''the machine yer sus the Hydraulics, proved beyond question that the machine was the better gold saver, for although the Hydraulics and Machine were TUT side by side, and so far as it was pos sible to judge, in similar ground, ye the cleanup from the hydraulics only showed a value of 1922 cents per GU bic yard, while that from the ma chine showed a yield of 2877 cent: per cubic yard" Gravel has beer frequently dug and washed by tn machine at the rate of three cubit yards per minute and although wash ing at this speed, careful banning O the tailings have failed to find gol in appreciable quantities"
 The question arises, what does thi mean for the placer fields of Arizona That they are very extensive is vel known and that they are rich is als well known. Hundreds, yes, thou sands of acres have been tested b, experienced placer miners and the report them from 25 cents 10 SIP per cubic yard and the banks froI five to fifty feet in depth The mos extensive of these fields are in Yuma Maricopa and Pima counties and lal ge areas are also known in Mohav Yavapai and Pinal counties. Beside these there are innumerable sma areas of from five to twenty acre along the streams of the mountai ranges.
 Placer mining in Arizona has, the present time, been almost entirel confined to rockers and small sluict along the small streams and the only when the rains or melting snow have enabled the parties to work. l no place to my knowledge has ar company tried the placer fields Arizona except the Lynx creek h. draulics near Prescott where the m chine referred to abGve has been
 work. Before the introduction of u machine they were dependent on tl heavy water in winter and that se dom lasted more than a month; no they will be able to use the machiI for most of the year. There are maI fields along the Hassayampa al other streams where water in abu dance can be had at all times of u year, which can be pumped in sui cient quantities at no great cost f the operation of such machines
 the Vulture mine could pump wat twelve miles to run an eighty stan mill; the Harqua Hala pump thr miles for a thirty stan mill and the Congress pun one and half miles a forty stamp mill, cannot a plac company afford to pump similar d tances the amount of water necessa to run these machines?
 The various localities where su operations can be conducted are
