A DYER CASs.oS BALL QUARTZ MILL TO BE ERECTED ON CONGRESS
 STREET.

Understanding that J. NJ. Dyer. the
 inventor and patentee Of Dyer's cannon
 bali mill, was in Tucson, and proposed erecting one, CITIZEN reporter sought the gentleman out, and gained a few points about the mill.
 The gentleman was found in Col J. $. tMorgan's office on South Meyer street, aud at once expressed himself
 willing to make anything public about his mill
 "I have rented the corral of ". R. Gleason" be commenced, "at tue foot of Congress street, and expected 10 have my machinery here yesterday, but the railroad washouts will delay me some time. l have obtained an engine and boiler of Noble < Hall, and lumber of J. \. Mason, and am all ready to put up my machinery when 1t comes. 1 am even so fortunate as to secure an abund- ant supply of ore to start, C. c. Steph- ems Esq. furnishing ore from his gold mine in the Sierritas."
 How long has your null been in- vented?
 It was patented October 8, 1882. I now have twenty-seven running in Cali foTnia, one in Oregon, one in Nevada and one in Idaho.
 How large a one do you purpose erect ing here?
 A six-ton mill: that Is one that will crush aud nave ready for the amalgam pans SIX tons in every twenty-four hours.
 Where did you first operate?
 l first put up three mills at Grizzly Flat Tn Fl Dorado County, California. They were put up at my risk. The Eagle mining company paid me for them at the end of two weeks. and ordered another. They can be run by any motive power, mule, water or steam. They are made n sections, and can easily be taken apart, and shipped on mule back over traIls tO places where other mills cannot be taken.
 How would you describe the mill.
 We'll, here taking up picture of one is a wooden frame about 7ls feet high and four feet wide. The top piece Is made movable so as to shift the top shaft from its center when particularly hard rocK Is to be run. The ore Is thrown in5o a hopper at the top, and passes into perpendicular hollow cyln- der of two inch cast iron, banded with heavy strips of wrought iron on its out side. Within this cylinder k a solid cast iron cone, two inches n diameter at the apex and ten at the base. By nov ing the top frame slightly to one side the cone IS thrown of its base and the rock Is turned around into closer quart l e-s. and Is broken. For instance, the space between cone and cylinder will be thrown from an even five inches on each | side 10 four inches ou one side and SIX l on the utEer. The SIX inch side will 1 carry rock around to the four inch side, l and there crush it. The broken rock | continues dropping till it gets to be | about as big as a coffee bean. It then l passes ont through some holes down l where the cannon balls get in their | work.
 The cone rests upon the upper track | bed, winch latter rests iu turn upon the | balls. IhIS masC5 no idle parts in the | mil. EVe-E Stlck Bnd iron has a respou- | -ia.e duty so perform, and does 1t. The | top Ss4tt, Nli.is connects the cylinder | Of tGa rock breaker with the top frame | O. beam, does hot .gu down through the | tracs-t eds and e 'un . | wa, ih.. mac in- cry. Auo. er ~u.fr e .f.Ercts the machin- -ry oi the engine wilA Ihr upper track be ]. and cone. The lower tr-ck-bed is stat -onary.
 After tIc ore has passed through the rock-breaker it droIs down under the cannon balls. These revolye round in tracks fitted 70 them in both the upper and lower beds, and crush (nOt grIud) | the httle pieces of ore into a pulp. The pUlverizing is thorough. This pulp is through a screen. and Is then ready for the amaigam pans, which lat ter process of course every miner under stands. The cylinder Is about If inches wide, and two and a half feet high.
 Has your mill thus far given satiafac- ton to practical miners?
 We'll, you can judge for yourself re- piled. MT. Dyer, handing the reporter a lot 1f printed testimonials from numerous parties who are running his mills. You can write to them and find out. But the best proof will be when l get my mill up here, and running, with the ore going Tn lt the top, and the pulp coming out at the bottom already for the pans, and then the gold coming out Of the amslgam.
 How soon will you be running!
 I cannot tell now. I did hope by next week. My mill cannot be here now on account of the railroad washOut for per haps ten days, and then 1t will take another week to get 1t mp. I will ad- yertise it in time for everybody to come and see for themselves. Of course this mill is merely for exhibition. Colonel Morgan here is my agent, and will have mills of the different sizes on hand for sale hereafte
