Report of the Judges on the 
Class 1.— Wrexham Sewage Fakm. 
The Wrexham Sewage Farm is the property of P. 13. Davies- 
Cooke, Esq., and is rented by the Corporation of Wrexham 
at 320?. per annum. It is now underlet to Lieut.-Colonel 
Alfred Stowell Jones, V.C., on a lease for nineteen years, which 
will expire in the year 1891. Twenty acres of additional land 
are rented by Lieut.-Colonel Jones from Sir Roger W. H. Palmer, 
Bart., at 21. per acre. The entire farm covers an area of 104 acres, 
made up as follows : —

The sewage of the town of Wrexham, which contains a popu- 
lation of 10,000 persons, flows by direct gravitation on to this 
farm. At the head of the farm are placed a pair of settling- 
tanks, into which the sewage flows, and in which the solid 
matters subside, the liquid flowing from these tanks being dis- 
tributed over the land by means of earth-cut carriers, except in 
a few instances where the carriers are earthenware pipes. All 
the sewage that finds its way into the tanks is passed on to the 
farm. There is, however, a storm-water overflow at the entrance 
into the tanks, and we were informed that there were others in 
the district. The quantity of liquid sewage conveyed on to the 
farm varies from 300,000 gallons per diem in dry weather to 
500,000 gallons in wet weather. All excess beyond the latter 
quantity flows by storm-water overflows into the adjacent 
brook, and we observed at the time of two of our inspections 
that the overflow at the entrance to the sewage-tanks was 
acting. The solid matters taken out of the tank are first allowed 
to drain, and then they are thoroughly dried and sifted ; a 
Gibbs's fan and cylinder, driven by a portable steam-engine, 
is used for drying the sludge, which is previously sold to the 
Wrexham Manure Company, who make a manure called the 
"Farmer's Friend." We were informed that 172 tons of this 
manure were sold in 1878 at 6Z. 10s. per ton, and that each ton 
consisted of — 
1 cwt. sulphate of ammonia. 
7 cwts. fine raw bone-meal, 
12 cwts. dried sewage-sludge. 
1 ton.
