the ground is waterlogged, and the houses are very unhealthy. In the school-house several deaths from fever occurred, and no teacher could be found to take the place.

small cost.

303. At Aberdeen a supply of good water is much needed, and could be procured at An abundant perennial stream enters the sea at a short distance to the eastward. A portion of its water has been diverted to irrigate gardens above the village, and to fill a tank, used for washing nets, which is private property, whence also the inhabitants and the junks get part of their supply.

304. The village of Stanley has declined in prosperity, since the abandonment of the barracks there. The water supply is deficient, being derived from shallow wells, which are nearly exhausted in the dry weather. Here also a water supply could easily be obtained from the streams to the north and east.

305. At San-Ki-Wan also a supply of water is required, the pipes which were put down about two years ago being defective. Side channels also are much wanted.

HOUSE DRAINAGE.

Extract from " Model Byelaws," pages 32–36, paras. 60-66.

60. Every person who shall erect a new building shall cause the subsoil of the site of such building to be effectually drained by means of suitable earthenware field pipes, properly laid to a suitable outfall, whenever the dampness of the site renders such a precaution necessary.

He shall not lay any such pipe in such a manner or in such a position as to communi- cate directly with any sewer or cesspool, or with any drain constructed or adapted to be used for conveying sewage, but shall provide a suitable trap, with a ventilating opening, at a point in the line of the subsoil drain as near as may be practicable to such trap.

61. Every person who shall erect a new building shall construct the lowest storey of such building at such level as will allow of the construction of a drain sufficient for the effectual drainage of such building, and of the provision of the requisite communication with any sewer into which such drain may lawfully empty, at a point in the upper half diameter of such sewer, or with any other means of drainage with which such drain may lawfully communicate.

62. Every person who shall erect a new building shall, in the construction of every drain of such building, other than a drain constructed in pursuance of the byelaw in, that behalf for the drainage of the subsoil of the site of such building, use good sound pipes formed of glazed stoneware, or of other equally suitable material.

He shall cause every-such drain to be of adequate size, and, if constructed or adapted to be used for conveying sewage, to have an internal diameter not less than " 4 inches," and to be laid in a bed of good concrete, with a proper fall, and with water-tight, socketed, or other suitable joints.

He shall not construct any such drain so as to pass under any building, except in any case where any other mode of construction may be practicable, and in that case he shall cause such drain to be so laid in the ground that there shall be a distance equal at the least to the full diameter thereof between the top of such drain at its highest point and the surface of the ground under such building.

He shall also cause such drain to be laid in a direct line for the whole distance beneath such building, and to be completely embedded in and covered with good and solid concrete, at least " 6 inches" thick all round.

He shall likewise cause adequate means of ventilation to be provided in connexion with such drain at each end of such portion thereof as is beneath such building.

He shall cause every inlet to any drain, not being an inlet provided in pursuance of the byelaw in that behalf as an opening for the ventilation of such drain, to be properly trapped.

63. Every person who shall erect a new building shall provide, within the curtilage thereof, in every main drain or other drain of such building which may directly commu nicate with any sewer or other means of drainage into which such drain may lawfully empty, a suitable trap at a point as distant as may be practicable to the point at which such drain may be connected with such sewer or other means of drainage.

64. A person who shall erect a new building shall not construct the several drains of such building in such a manner as to form in such drains any right-angled junction,
