the time the mill was built. At present water Is supplied by duplex steam pump located near the creek. which Is about 300 feet from the mill. This pump elevates water to two cypress tanks on the hiil- side, and to tanks in chorination build ing.
 Roasting Furnace.
 This plant comprises a double-hearth reverbatory furnace with hearths about 6x4o. substantially built of brick with a double brick draft stack
 The concentrates are brought by small tram car to the top of the furnace where they are charged through suitable open ing on to the hearths, where they are stirred and manipulated by robbling irons till thoroughly roasted. the time depend ing on character of concentrates. The heat for roasting Is supplied by a wood fire near one end of the furnace. the heat ed gases passing over the lower hearth to the far end of the furnace and return ing over upper hearth to the draft stack, at the fire box end. The operation Is as- sisted by combination of sulphur con- tained in the pyrites themselves. When roasting operation is finished the roasting concentrates are removed from furnace and spread on a brick cooling floor. The furnace has capacity of two and a half tons of roasted concentrates in twenty four hours.
 Chlorination Mill.
 This plant is installed in ave-story frame building 26x32. It was recently built, and. for reasons mentioned later. has been in operation very little. The concentrates from some 500 tons only have been run through the plant. The roasted concentrates. from the cooling floor, are shovelled into the boot of bucket elevator. which takes them to the top of the mill and discharges them into travelling hopper. This hopper is pushed over the charging hole. and emp ties its charge through a funnel into the chlorinating barrel, which is installed on the fourth floor. The chlorinating bar rel is cylindrical in shape. 40 inches in diameter by 60 inches long inside, made of cast iron and lined with lead. Trun- nions are affixed to the heads and sup port the barrel in a timber frame with cast iron journal boxes. The charge con- sisting of one ton of roasted concentrates, about I2 pounds of calcium chloride. and F pounds of sulphuric acid is introduced through the charging hole in the side. The hole Is then hermetrically sealed and the barrel revolves for about five or six hours. power being furnished by a small engine on same floor. The nascient chlo- rine acts on the gold forming a terchlo- ride of gold.
 The charge is emptied from the barrel onto sand filters on the third floor and the soluble chloride of gold Is leached out by water, and the solution run into storage tanks on the first floor. The residue is shovelled out of filters and run through a chute into the tailings car be- low, and discharged from mill.
 The solution is drawn off from the stor- age tanks into the precipitation tank, where by the addition of ferrous sul- phate the gold is precipitated as a brown spongy precipitate. This is cleaned up at stated times. melted in crucible with soda and borax and the gold cast into ingots or bars. These are shipped to the United States Assay Office where its fineness is determined and a certificate of deposit sent to producer. There are suitable acid, solution and water tanks in the building. The plant is in good condition; but a few minor changes could be made which would reduce the labor in handling the material.
 The Camp.
 The camp is situated at the mill Is well arranged on the hillside, facing Hill labee Creek, and presents a very pie turesque appearance. There is a com missary. office, cottages for officers and laborers, wagon sheds and stables.
 There is another commissary with farm houses, stables. etc., about a mile from the mill. and there are numerous small houses scattered about the lands. The houses at the camp are all painted with red mineral paint and trimmed with white. A plentiful supply of good drink ing water is supplied by numerous springs on the place.
 The Ore Bodies.
 Numerous veins of auriferous quartz traverse this property, the general trend of these veins being N 20 degrees E., but subject to some variation. as will be ex- plained.
 I first made an examination of the mine and beginning near the mouth of Quartz Creek east of the mill we travel led first on a line crossing the auriferous leads nearly at right angles, and in distance of less than half a mile we crossed probably twenty quartz veins. about fourteen of which have been pros pected with small prospect pits and eight of which have been extensively worked by open cuts and tunnels.
 We crossed and recrossed the forma- ton several times. visiting the numerous pits and open cuts. We then followed some of the veins for a distance of about mile northward and found that they diverge some of the veins on the wes: side showing a strike of as much as N. 10 degrees w. The veins are conform aDle with the slates and are lenticular. being only a few inches in some places and several feet in others.
 Most of the older pits are filled or par tially filled by rain wash and the veins not sufficiently exposed for a fair exami- nation. Most of these are oxidized at the outcrop; but some are sulphurated from the surface. There is a large amount of float quartz on the surface of the ground. and banned a number of samples picked up at haphazzard and with very few ex- captions found traces of gold. I also banned a number of samples from the veins, taken from the open cuts. Most of these also yielded gold The gold found in banning was all very fine. I did not see a single sample where gold could be detected in the rock. Some of the samples did not show gold in banning. but assays from the same veins show from traces up to $500 per ton.
 The veins, as shown in the pits, would seem to be in three groups. One, the Mill series. on which most of the old work was done. lie in nearly parallel di- rections in the hill just above the mill and only a few feet from each other. These have been traced northeast for several miles, passing through Ely Pits, Log Pits and Goldville. The Middle sys- tenn running nearly north, has at least three good veins. One of these veins is opened in a hollow and nearly three fourths of a mile northeast of Mill and shows apparently three feet thick be- tween walls of mica schists, and strikes nearly due north. The pit was so much filled in with rain wash that 1 could not get 1t exactly. About 1.500 feet north of this point another pit is opened on what Is supposed to be the same vein and
