During the year four wells were closed by order of the Board, the water being unfit for potable purposes; these wells were situated at 15, Kowloon Street, Kow- loon City; in Ribeiro's bungalow, Kowloon; between 15 and 16, Fuk Sing Lane, Victoria, and between 76B and 784, First Street, Victoria.
GENERAL SANITARY CONDITION.
The houses which are now being erected in accordance with the provisions of the Public Health and Buildings Ordinance No. 1 of 1903 are a great improvement on the existing type of house, especially in respect of that provision of the Ordin- ance which permits the kitchens of tenement dwellings to extend across only one half of the width of the house. This enables the long narrow living rooms -which constitute the invariable type of the Chinese dwelling in this Colony-to be adequately lit and ventilated from the back as well as from the front, and thus a far more sanitary dwelling is secured. Under the Ordinance a certain amount of land has been resumed in respect of scavenging lanes, its total area being 428 square feet while in connection with the general resumption scheme for the improvement of the sanitary condition of the City, an area of 24,898 square feet has been resumed during the year in one of the most overcrowded areas, and the buildings are now being demolished for the purpose of forming a wide street through the block. In addition, an area of 1,650 square feet, on which stands a Coolie House for the chair coolies at the Peak, has been resumed for administrative purposes.
During the year a public bath-house in Pound Lane has been completed and opened and a public latrine has been opened on the West bank of the Bowrington Canal while three public urinals have been opened in the City.
