MopE ABOUT SrLpurpErs.- AS every ything touch ing upon the .ulphurc; question is of interest Co 4 iarc, clas, of our readers, we print the follow ing from the .ihd
 "Latcly the attention of miners has been at- tracicd to the Ritlenger sizing Boxes and Pcrcus- sion Table which have been tried in the Gold Valley mill and have given complete satsiac- tion and as there are many inquiries about them and indeed general demand among quartz miners for information about them. We describe them They have been used in Hungary many wears. and are therefore not uutried Their ma teral is wood and construction simple. SO they are cheap and can be made by any carpenter. They require little power and no attention, do their work well and last a long time.
 The sands run from the mortar of a tiyc-stamp mill into a succ which is four inches wide at the ! head ten at the foot, and twelve feet long with 1 a grade three quarters of an inch Co a foot Near the head of the sluice is the first sizing box which ! is hopper. or hollow pyramid. the mouth being ! as wide as the sluice, and foot long. The hop ! per is a foot deep and at the bottom IS dis 1 charge through pipe half an inch in diameter. l This box has suphurets at tlc bottom and water above so the current flows evenly over it. The 1 slucc being narrow and the current strong, only l the coarsest suiphurcts drop in here. The dis l charge allows the suphurets to run out as fast as they enter the box. Three feet below the first hopper is another, seventeen inches wide, twen- l " clEut incntr lDnE anu SCNtui'th iltU'N hE'p
 The width of the sluicc is greater here the water
 is shallower and thc current slower the sul
 phurets which sink into this box are finer Th,
 third box is three feet further down. ten in
 ches wide, and three feet long and two feet deep
 This catches the finest ulpburets, and the matter
 that passes over is worthless. kustel. speaking
 of sorting or sizing ,ulphurets, says the pointed
 boxes are the best of all cOntrivances for th purpose

 hangs upon iron rods. On one side k cam
 wheel which strikes the table from sixty to nine : " blows a minute. knocking it sideways thre Q quarters of an inch against strong springs whic

 sizing box run upon the upper corner of the tl o bic, on the side next the springs. lt the tobi | stood still the sand and sulphurcts would ru |, down near the side upon which they start; bu 5 the percussion throws tue sulphurets over Co th

 are made together, and present a surface cigl t feet square, with a board partition down th F middle. Three such double tables arr needle
