Lammerlaw Greek Hydraulic Gold-mining Company, Waipori (W. E. S. McKnight, manager).—(l 3/12/99): Claim at junction of Lammerlaw and Nardoo Creeks; sluicing and elevating. Face about 9 ft.; old tailings and peat on top, and 12 in. of wash on the true bottom. Chinese employed to clean up the crevices and inequalities of the bottom with hoop-iron scrapers and scrub-brushes. Sixteen miles of race ; eight heads of water ; 250 ft. pressure ; one elevator ; and two nozzles. Seven men employed. Farrell's Deep Lead, Waipori (James Gare, manager).—(l 4/12/99): Work at present confined to a spur on Mr. Cotton's private property. Ground leased under arrangements of acreage rent and royalty on gold won. Elevating, 30 ft.; face, 12 ft. (top clay 4 ft., gravels 5 ft., gold-bearing wash 3 ft.). The gold is very fine, and, as the boxes are only 48 ft. long by 3ft wide, the probability is that a considerable proportion of gold is carried over into the tailings. Venetian riffles and perforated plates are used, with cocoanut-matting and calico underneath. Deep Stream Amalgamated Hydraulic Sluicing Company (G. Heideman). —(4/1/1900) : Water is brought in eleven miles from Scrubby Creek, the main branch of the Deep Stream. Penstock 350 ft. above claim. 1,400 ft. of 13 in., 1,400 ft. of 9 in., and 500 ft. of 7 in. pipes in use. Eighteen heads of water available, and two paddocks at work; one elevator and one nozzle in each, also independent pump for use when claim idle, as Mr. Heideman does not believe in running clean water over his angle-iron ripples on account of the scour set up by doing so. Face, about 20 ft. 15 ft. of quartz-drift, and 5 ft. of silt on top. Gold fine, and principally on the bottom (schist). Sixteen men are employed. Post-office Greek Gold-mining Company, Verter Burn (S. B. Carpenter, manager). —(5/1/1900) : Elevating and sluicing claim, formerly Parker's, who left 12 ft. to 14 ft. of false bottom, which is now being elevated. Occasional runs of gold are also followed into the bank on top of the false bottom. A face of quartz-drift 60 ft. to 80 ft. high runs up the east side of the paddock. I warned Mr. Carpenter that great care should be exercised in working under such a high face. Seven men are employed. Evans and Tillie, Orepuki.— {2o/1/1900) : Driving and blocking out. Only one opening. Drive 6 chains to face. Air fairly good, but it must be very bad at times, the running of the truck backward and forward being the only ventilating medium. Timbering excellent. Five men are employed. Wallace and Whalen, Orepuki. —(2o/1/1900) : Face above mine-mouth top-heavy, and ready for falling. Instructed the manager to trim and keep a good batter on the bank. Plenty of good timber used. Forbes, Orepuki.— (2o/1/1900): Driving and blocking out. (21/1/1900): Sluicing. Levy and Sorgenson, Orepuki. —(20/1/1900) : Driving and blocking out. This mine is nearly finished. Taking out the last block. Undaunted Gold-mining Company, Orepuki. —(2o/1/1900): Driving and blocking out. Mr. Corbett was ill, and unable to show me round. Local Industry Gold-mining Company, Lawrence. —(6/2/1900): Working at lower end of claim. Face, 12 ft. to 14 ft. ; mostly old tailings. This is the first elevator at work on this part offthe claim, but the ground has all been turned over several times by Europeans and Chinese. Gold on the bottom shotty, and that in the old tailings very fine. An average of seven men employed. Blue Spur, Lawrence (J. Howard Jackson, general manager; J. McHattie, mine-manager).— (6/2/1900) : Three faces at work; two nozzles in each face. The cement is very hard, and has all to be blasted out of the face. The lumps are further broken up by men with mattocks, and the material is then sluiced to the elevators. The present bottom is being carried along on a sandy bar, below which the ground is much poorer. At the centre of the claim the face is over 100 ft. high. The disposal of the tailings is giving the management some trouble, owing to the slight fall there now is between the delivery and the tailings-heap. Being short of water, work only equals one and a half shifts per day.- Thirty-five men are employed. Kitto, Hancock, and Party, Munro's Gully. —(6/2/1900): Elevating tailings from the old spur claims, and cleaning up bottom, which carries very fair gold. Working back to the cement in the spur. This claim at present employing nine men working one and a half shifts per day, and has many years' work before it. Mills and Brown, Upper Evans Flat (E. Mills, manager). —(6/2/1900): Elevating claim on the roadside. Face, 10 ft. ; half old tailings. The bottom is new ground. Water is brought in from the Tuapeka River (nine miles). 200 ft. head of pressure. Rough gold on the bottom (schist). Six men at work. Goldm Bise Hydraulic Elevating Company, W ether stone's (Donellan, Smyth, and Adams). — (7/2/1900): Elevating-ground being now worked for the fourth time. Worked previously by Europeans and Chinese. Seven men at work. Sailor's Gully Elevating Company, Waitahuna Gully (A. Barr, manager).—(7/2/1900): Working near the head of the gully. Face, 5 ft. to 6 ft. Ground being worked the third time. Schist bottom. Water is brought in from Waitahuna heights. Race, twenty miles. 2,000 ft. of pipes, and 250 ft. head of pressure. Seven men at work. Quitter and Sons, Waitahuna Gully. —(7/2/1900) : Hydraulic elevating. Not at work, being short of water. Three men usually employed when working. City of Dublin Gold-mining Company (J. Ferris, manager).—(7/2/1900): Ground-sluicing. Blue-spur formation. T drives are put in at the level of the tail-race, and the face brought down with powder. The loosened material is sluiced into the tail-race with water at a pressure of the height of the face, 80 ft. This system leaves a large proportion of the cement underfoot in the trough or gutter of the V-shaped formation, and which can only be treated by elevating, for which purpose there is not pressure and volume of water at present available. The tail-race is about 720 ft. long, having 50 ft. of angle-iron ripples and cocoanut-matting at the top. The rest of the
