New Concentrating Plant. a Part o
 Val verde's Reduction works


 Alter visit to the new Standar concentrating plant at Val Verde representative of the Prescott Pros pect writes as follows:
 The reduction works that have sucl erected there, about three hupdreI feet south of the Val Verde sme,te on the banks of the Agua Fria ar, as near perfection as one ever sees and all that any man could or woul, ask. mere. under three or four capacious roofs are two separate and complet, milling plants with concentr ators fol eacn. To begin with we find A first CESS ten-stamp mill with silver plated plates and these, of course, lead down to the Wilfiey concentrators where the metal is prepared for the big smelter over the Verde works.
 It is a pleasure to walk through tnose big buildings, especially if won are under the intelligent guidance of Harfy Paulson, who showed the writ. CT everything that was to be seen and explained it all in the most lucid and agreeable manner. l started out by making the assertion that there are distinct plants under that one large roof-or collection of roofs, and I did not exaggerate, for on the left side of the great substantial building, which looked strong enough to withstand the slings and arrows that fly around on the Agua Fria under ordinary cir. cumstances (meaning the summer rain storms), there is as much per. feet machinery for the reduction of the ores of this district as can be seen in this county.
 MT. Paulson, the manager, showed me over the works in the most polite and engaging manner, explaining at length the workings and importance Of several new pieces of machinery that greatly simplify the reduction of the ore One especially, named the 'sizer. of which there were several dn attendance on the rolls" separat- cd the sands into different sizes. thus making a great saving of water on the concentrating tables. The heavier sand would of course need the most water. while the lighter shines would not need so much.
 The "sizers" are something new and were introduced by MT. Paulsen. who takes great interest in their cor rect working, and they are undoubt- edly a great saving in the use of wa il. country where that important fluid is not too plenty
 On the north side of the huge build ing the new, up-todate ten-stamp mill keeps its stamps dropping and the pulverized ore gliding over the plates leaves what free gold it carries and passes op 10 the sizers and thence to the Wilfey concentrators
 On the south side are two sets of rolls" which the writer is not well acquainted with. But if they do exc cution in proportion to the racket they make they must be efficient From these rolls the product also goes first to the sizers and then to the Wilfleys, unless it is the finest kind of shines, in which case it goes over the Frue vanners, which saves the concentrates perfectly.
 In truth the Standard is a complete and perfect plant and those who have not seen the entire process of reduc- ing ores in the latest, most improved and satisfactory manner would be much interested in following the rock from the time it leaves the freight car and enters the rock breakers and continues on its downward course. That which enters the left hand rock breaker goes direct, by self feeders to theaheavy stamps and passing over the plates where the free gold is enm- mated Is shatched ID by elevators which rake it 'pp to tic sHzers" where it is separated into three sizes of sand and slime and is passed on to the concentrators. After. this ordeal it is ready for the briquetting machine of the Val verde smelter, which presses the wet concentrates into su- gar loaves about i've inches in diam eter by two inches thick. This bri- quetting is necessary because were the fine tailings shoveled dry and in their sandy form into the furnace would be immediately blown out of the smoke stack by the blast.
 This great mill is furnished with two engines. one of which works the nine concentrators alone, while the other moves the remainder of the ma chinery. The railrod spur passes close to the west side of the building and there are always cars of ore ei- ther going or standing there. In spite of the magnitude of these, works and the number of machines in
