reducing liability to block. The gold is saved in the open tail-race leading to the tunnel. Longitudinal °steel rails and Aspinall's patent heart-shaped riffles are used; that they are effective is proved by the tunnel having been washed up several times when the quantity of gold won did not pay for the labour expended. Two men employed. " Shipper's Sluicing Company, Londonderry Terrace, Shipper's (William McPherson, manager).— (24/4/1901) • The tunnel tail-race being blocked, all hands were employed laying pressure-pipes down the first rise to enable water being turned on to the block. The water was turned on and the block successfully removed during the afternoon shortly after my visit. The manager intends to reduce the several right angles in the tunnel rises, and, the paddock (as now opened up) being large enough to enable stones being stacked, it is anticipated that the liability to block will be minimised. The face of the claim (which is about 140 ft. in vertical height) will also be given more batter by running top stuff off first. The water-supply is brought in from Skipper s Creek, the race bein« five miles in length. Six deep intervening gullies necessitated siphons being used, the longest of which, over Skipper's Creek, is 1,760 ft. in length, the diameter of the pipes being 28 in. Two storage-dams have been made, from which the water is taken into the claim by 1,000 ft. ot 11 in. pipes ; vertical pressure, 150 ft. Two 5 in. nozzles are used alternately m breaking down the face.' The gold-saving boxes are laid in the tunnel tail-race. They are 350 ft. in length and 3ft. wide. Longitudinal iron rails set in frames, and held in position by side pieces, are laid on top of scrub in the°boxes for gold-saving. Six men employed. Bobert Johnston, Pleasant Greek Terrace, Skipper's.— (24/4/1901) : A large paddock Has been sluiced away on the stony end of the claim. Water-supply being plentiful, the whole of the terrace is bein" sluiced away. Water is turned over the working-face from an iron box shoot, and, having a fall of 100 ft., good work is done thereby. Canvas hose is used in the claim, the owner preferring it to iron pipes, being more easily handled. The hose is well tarred before use, and is said to last from three to four years. Two men employed.
