During the year very large additions have been made to the 
wharfage and storage accommodation at Circular Quay, and other 
parts of Sydney Harbour. On the Richmond a scheme for reduc- 
ing the damage done by floods is now in course of construction, 
and extensive embankments for the protection of the town of 
Grafton were also completed. 
A dredging plant of forty dredges and twenty-nine steamers 
has been continuously at work during the year, and over six 
million tons of material have been lifted. 
Several water supply schemes for country towns are in hand 
or have been completed, one of the most important being at 
Junee, where a concrete dam over forty feet in height has been 
erected. 
One of the principal works to engage the attention of this 
branch was the construction of the Naval Depét at Garden 
Island. A considerable portion of the island has been levelled 
down and the material used for its extension to give room for the 
necessary buildings. The barracks is a building of three floors, 
capable of accommodating officers and men, and is fitted on 
the most approved plan, the sanitary arrangements having 
received special attention. The workshops, two hundred and forty- 
eight feet by one hundred and thirty-two feet, include a machine 
shop, boiler shop, foundry for iron and brass, forge shop, tool and 
pattern shops, dynamo room, zincing room, engine room, boiler 
house, offices, etc., and have been fitted with machines capable of 
undertaking any naval work demanded of them. The naval and 
victualling store is a building two hundred and twelve feet by one 
hundred and twenty-eight feet. It has four floors, having 4 
superficial area of ninety-four thousand feet, and is provided with 
five hoists and two lifts, with the necessary hydraulic plant. The 
coal store is capable of holding two thousand five hundred tons, 
and extensive coaling wharves have been provided to which all 
the stores are connected by lines of tramway. In addition to 
the main buildings, there are stores for inflammable materials, 4
