Class 2. — Doncaster Sewage Farm. 
This farm is the freehold property of the Corporation of 
Doncaster and of Lord Auckland, 26 acres being the property 
of the last-named owner. It was partially laid out by the 
Corporation of Doncaster, and has since been completed by the 
tenant. The farm has been let on lease for fourteen years to 
Richard S. Brundell, Esq., and the lease will expire on the 2nd of 
February, 1887. The farm contains an area of 304 a. 3 r. 11 p., 
of which 229 a. 1 r. 27 p. were irrigated in 1878, 75 a. 1 r. 24 p. 
not being irrigated ; it was established in 1873, and receives the 
sewage of the town of Doncaster, which contains a population 
of 21,000 persons. 
The sewage of Doncaster is collected at a low point in the 
town near the river Don, where the pumping station is placed, 
and whence the sewage is pumped through a 21-inch cast-iron 
main about two miles in length on to the farm, at a cost to the 
Corporation of Doncaster of about 350Z. per annum. The cost 
of the pumping station and of the delivery main to the farm 
has been 18,000/. At the pumping station there is an overflow 
from the sewers into the river, through which the sewage is 
discharged in times of storm or other periods when the sewers 
are surcharged. At the pumping station there are a pair of 
compound beam engines with wrought-iron beams working two 
pumps direct from the beam. The whole of the sewage pumped 
on to the farm has to be lifted to an elevation of 52 feet. The 
delivery of the sewage on to the farm, however, only takes 
place in the daytime. At night it is stored in a tank-sewer 
capable of holding 250,000 gallons of sewage, which is placed 
in the lower part of Doncaster. At the sewage works there are 
fixed in the sewers cages which form screens to keep out the 
larger solid matters from the pumps, all the rest of the sewage 
being pumped on to the farm. At the highest level of the 
sewage farm there has been constructed a triangular sewage 
tank one acre in extent, for the purpose of the storage of sewage ; 
but experience has shown that it is undesirable to use this tank. 
When the sewage arrives on the farm, it is distributed through 
earthenware pipe carriers, laid either in embankments or im- 
mediately below the ground. These carriers occupy all the 
high portions of the farm, whence the sewage is distributed 
over the land in earth-cut carriers. The earthenware carriers
