Clyde. The Clyde Dredging Company has a very complete plant, the dredge being 93 ft. long by 27 ft. wide over all, and bucket-ladder 60 ft. long. The tail elevating-buckets are of an improved shape, and are intended to carry away all sand and gravel washed. A second small set of elevators will lift the grit and fine sand passing over the tables, and empty it into the main elevators at the level of the deck, to be discharged with the coarser gravel some distance away from the tail end of the dredge. The object of the tail elevator is to give the dredge plenty of room in the deep ground, or where a large quantity of loose gravel has been deposited in the river by terrace sluicers. In order to strengthen and prevent the dredge hugging, she is fitted with two sets of hog-posts, 28 ft. high, four in each set, diagonally braced, and having long iron tie-rods at top from the ladder hoistingframe at the bow to the outer end of the tailing elevator. This deck erection to such a height is considered quite a new feature in dredge construction, and it is thought it will be more generally adopted where deep ground has to be worked. Alexandra. The Chicago Dredging Company hold 57 acres 2 roods on the Clutha River, near Alexandra, and employ seven men, the dredge being worked by steam-power. The Eureka dredge, 80 ft. long, with pontoons 9 ft. wide and 5 ft. deep, ladder 53Jft. long, and ladder-way 4-J-ft. wide, works the river-bed half a mile above the Alexandra Bridge. The plant is capable of dredging 36 ft. deep from the water-surface, the capacity of the buckets being 3 cubic feet. The tailings-elevator, 36 ft. long, is capable of stacking the tailings 20 ft. above the water-level. The Ngapara Gold-dredging Company, at Alexandra South, put through during the year 225,600 yards, for a yield of 940 oz. ; value, £3,619. The dredge is worked by a 12-horse-power steam-engine.

The washing cylinder is 16 ft. long, the perforations being fin. in diameter, and the material treated is distributed over 220 square feet of gold-saving tables, from which the sand is discharged directly into the tailings-bucket, which casts the tailings some distance behind the dredge, where, if necessary, they can be stacked to a height of 24 ft. above the water-level. The fall in the gold-saving tables, which are all fitted with cocoanutmatting, is 1 in 10. Ophir.
