at the cost of the Earl of Warwick. The preparing of the 
adjoining lands for the reception of the sewage was done by 
those of his Lordship's tenants who receive it. During the 
year 1878 about 45 acres of land were irrigated with sewage 
by the adjoining land-holders. This area received in that year 
521,232 tons of sewage, being at the rate of 11,583 tons per acre, 
or to an irrigation depth of 114-R inches. 
The sewage of Leamington is first brought by direct gravita- 
tion to a site near the river Learn, where there are two sewage- 
tanks ; one a covered tank capable of containing half a million 
gallons, and the other an open tank capable of holding one 
million gallons. There are also storm-water outlets from the 
tanks into the river, so that at any period the excess beyond 
what may be stored in these tanks passes direct into the river. 
The average daily quantity of sewage pumped during the past 
seven years on to the farm has been 823,500 gallons. Along- 
side the tanks, the pumping-station has been erected for lifting 
the sewage on to the farm at Heathcote, which is distant 
about 2^ miles ; it is lifted up to a vertical elevation of 
132 feet in order to command the whole of the lands at 
Heathcote for the purpose of irrigation. The cost of pumping 
is defrayed by the Corporation of Leamington. At the 
pumping-station there are a pair of condensing beam-engines, 
having a stroke of 8 feet, the steam cylinders being 36 inches 
in diameter. Each engine works a pair of single-acting pumps 
26 inches in diameter, which are placed at half distance at 
each side of the beam. There is but one fly-wheel to the 
pair of engines, which make from 11 to 12 strokes per minute 
when in full work. The iron rising-main for conveying the 
sewage from the pumping station to the farm is 20 inches in 
diameter for the first half mile, and 18 inches for the remaining 
If mile. At the time of our inspection on the 4th of June 
last, the water-pressure indicated in the engine-house on the 
rising-main was 65 lbs. to the square inch. The engines are 
usually employed in raising the sewage on to the farm from 
6 A.M. to 4 P.M., and there is a direct telegraphic communica- 
tion between the sewage pumping-station and the farm, by 
which all notices referring to the times of pumping and the 
quantities pumped are transmitted. We understood that the 
cost of the works undertaken by the Corporation of Leaming- 
ton for the disposal of the sewage, including the expenditure of 
8500/. for the tanks, which were originally made for working 
the A. B. C. process of clarifying sewage, has been 24,000/. ; 
and it further costs the Corporation of Leamington from 800/. 
to 900/. per annum to pump the sewage on to the farm, against 
which they have the set-off" of the amount paid by the Earl of
