Breakwaters.—The Breakwaters are formed of nibble stone blasted from the Quarries at Naval and Officer's Points, and deposited on the respective sites as shewn in the model—the outer slopes of both Breakwaters are protected or faced with huge blocks of stone. The Officer's Point, or Eastern Breakwater, is some 2,010 feet in length, with a width of 40 feet on top, and having an elevation of 6 feet above high water spring tide. The Naval Point Breakwater is 1,400 feet in length. The former breakwater has also a timber breastwork built along its inner face for nearly its entire length—known as the Gladstone Pier.

Water Area Enclosed.—The area of water enclosed within the Breakwaters is about 110 acres.

Dredging.—Dredging operations have been proceeding almost uninterruptedly for the past three years, during which period 756,090 cubic yards, or 1,049,725 tons of dredged material, consisting of stiff clay and mud, have been removed, at an average cost of 6¼d. per cubic yard. The Dredging plant used has been a single ladder Dredge and two Steam Hopper Barges, the holding capacity of the latter being 250 tons each. The dredged material is removed by them to a distance of miles, and then deposited. The present depth of water inside the Breakwaters and at the Wharves varies from 16 feet up to 23 feet at low tide. The rise of tide being about 7 feet, vessels up to 2,700 tons can now be safely berthed at the wharves.

Moorings.—Eight sets of Mitchell's Patent Screw Moorings are laid down in the Inner Harbour, capable of holding vessels up to 2,000 tons.
