Tn this boring the first 4424 feet is referable to the Triassic Pebble 
Beds, the last 68 feet belongs to the beds occurring between the Pebble 
Beds and the Coal-measure at Winwich, Parkside, and Collins Green, 
containing iron pyrites, and underlying marls of Permian age. The 
wells were commenced in June 1886, and the boring was completed in 
September 1887. The surface level is 100 feet above Ordnance datum, 
the normal level of the water is 91 feet above the same datum, andis reduced 
by pumping to 57 feet, and is kept at that level, having a column of 
107 feet of water in the well; the yield is two million gallons per day, 
but if the water be pumped down to 9 feet below Ordnance datum, the 
yield is not less than four million gallons. Water came into the well 
freely from 28 feet from the surface, the water apparently coming in 
from the south-east. The wells and tunnels yielded nearly a million 
gallons daily before the boring was commenced in May 1887. The 
supply of the well and boring may be considered to be wholly from the 
Bunter Pebble Beds. 
The Kuowsley pumping station consists of three wells, connected by 
adits and bore-holes from two of them. The most southern is called the 
Permanent well; it is 104 feet in diameter, and 173 feet in depth ; from 
141 feet to 164 feet is a chamber or adit, 23 feet by 6 feet, and 30 feet in 
length, ranging N.N.H. to the Pilot well. The surface level of the Pilot 
well is a foot below the Permanent well; it is 171 feet in depth and 
10} feet in diameter ; from the bottom extends a boring 250 feet in depth ; 
821 feet from the surface ; an accident happening at this depth, another 
well and boring was carried out, known as the Six-feet well. The latter 
is the diameter named, and 161 feet in depth ; a boring was carried from 
the bottom, a depth of 526 feet, or 687 feet from the surface. The latter 
well and boring were entirely carried out in the year 1884. The details 
of the section are given in the fifteenth Report. The details of the first
