During the year, twelve wells have been closed by order of the Board on con- sideration of the reports of the Government Analyst on the quality of the water yielded by them, and of their situation. Six of these were in Hongkong and six at Kowloon. Samples of water from three other wells at Kowloon and two others in Hongkong were reported on by the Government Analyst and in consequence of his report it was not considered necessary to close the wells.
GENERAL SANITARY CONDITION OF THE CITY.
pro-
Although comparatively few buildings have as yet been erected under the visions of the Public Health and Buildings Ordinance, yet such buildings as have been put up
shew a marked improvement in the matter of open spaces about them when compared with old buildings.
When a new building is erected on the site of an old building in a row of houses the shape of the old site does out afford sufficient opportunity to build a house of quite a new type. What is required in Hongkong is a new type of Chinese house and this will surely not be obtained unless houses can be re-built in blocks so that the frontage of houses and consequently the available window area may be much wider for the depth of the houses than at present.
In Hongkong little or no attention has been paid to the necessity of adapting houses to the requirements of the community and therefore the working classes have had to adapt themselves to existing houses.
This has resulted in the present insanitary condition of the houses of the working classes of Chinese.
In Great Britain much has been done latterly to provide houses for the work- ing classes; affording the tenants the necessary privacy and independence and at the same time adequate lighting, ventilation and other sanitary requirements.
It should not be difficult to model some scheme to effect this in Hongkong taking into consideration the local conditions and adapting the scheme to the place. This I fear cannot be effected merely by the re-building of houses one by one on their old sites but only by concerted action.
