rammed in, but where the ground would not present a sufficiently firm foundation for the pipe, the contractor to excavate to such increased depth as may be required or necessary, and shall make good to the required form and level with concrete

To fit up the trenches of the drain-pipes as follows: the soil on each side, and 6 inches over the pipes, to be carefully laid in so as not to disturb them, and solidly rammed down.

The trenches to be then filled with layers of earth, 12 inches deep at a time, each layer being well rammed over the whole surface.

The first layer to be placed over the pipes with a shovel and not from barrows; the pipes not to be walked upon until this is done.

To execute all the brickwork in Roman cement necessary to form all cess-pits for the gully shoots, with their inverts.

The bricks to be of good, sound, whole, hard, wellburned stocks, of uniform shape and size.

The Roman cement to be the very best, used fresh, and mixed with clean sharp sand, in equal proportions. The pipes used to be those known as Jenning's Patent Saddle Pipes, 12 inches in diameter, the gullyshoots being 6-inch socket pipes of approved manufacture; each end opening into the drain to be trapped with a galvanised iron-mouth plate, properly hung.

Fit two flushing shafts where indicated on section, formed with 6-inch socket pipes bedded in concrete, connected at the lower end with the pipe sewers, and at the upper with the brick chamber for receiving same. Form brick chambers of 9-inch brickwork, and footings built in cement for flushing box; and fit thereto a strong cast-iron flushing box, with hinged flap and key complete.

Provide all junctions, curves, tapering lengths, &c., of the most approved kind.

The pipes to be laid truly in line, with true gradients throughout. To prevent the sand from getting into the pipes, the joints to be bound with a band of welltempered clay.

The interior of the pipes to be carefully freed from all dirt or clay as the work proceeds.

To properly bed on the cess-pits, cast-iron gully gratings, and frames 1.6 × 1.6, in separate pieces; the grates to be made to open and fasten with cast iron catches, pinned to the grates with wrought-iron pins.

The line of pipes shall not be covered until they have been examined and approved of by the surveyor.

The greatest care to be taken to replace the broken brick, rubbish, and ballast in the roads in its original position when the drainage shall have been completed. A. This is the specification marked A referred to in the contract between and the

dated this 24th February, 1863. The contract for this work was 4527. 15s. 10d., complete.

X.-Specification of SEWER WORKS at Hastings.

EXCAVATION.

The ground to be opened to the necessary width and depth for building the sewer in such lengths at one time as the surveyor shall direct, and as each length is opened the sides of the excavation shall be supported and kept open by suitable timber, so as to prevent the ground from slipping in until the whole of the brickwork is completed. In each length the foundation for the re

ception of the invert shall be cut out to the exact form and depth required before any of the brickwork is laid, and, should any irregularity be found to exist, it must be made up with clay or clean gravel firmly rammed in the vacant space; if any between the side walls of the sewer and the sides of the excavation shall be filled with clay or earth such as the surveyor approves, and shall be rammed in solid with proper beaters, so as to prevent any distortion of the form of the sewer, and after the arch of the sewer is turned over, the open space shall then be filled to the original height of the surface with layers of earth not more than nine inches in thickness, each of which shall be carefully punned before laying on the succeeding layer, two men being employed in punning to one man filling in, and so in proportion for any number of men.

All the superfluous earth and rubbish arising from the works shall be carted away with all convenient speed, as shall be directed from time to time; should any clay be dug up from the excavation, so much of it as will form layers of inches in thickness each shall be laid next to the arch of the sewer, and well rammed down.

The digging for the junctions of the sewers, as shown on the plans and in the sections, to be performed in a manner similar to that above described.

The contractor will be required to open and excavate the trench for the sewer through its whole length, and he will not be allowed to tunnel any part thereof.

BRICKWORK.

The sewer is to be built in brickwork of the form shown in the detail drawings.

The side entrance to be formed in the said sewer in
