The section revealed by the boring conforms most remark- 
ably to this classification, bearing in mind that the survey is 
an average and deductive section. We get 131 feet to the 
base of the Flags and Rough Rock ; the Survey average is 141 
feet. We get 200 feet of shales if we class No. 12 with the shales, 
against 153 feet in the Survey. It may be, however, that No. 
12 is part of the White Sandrock, which has 11 feet of shale 
parting here, or No. 12 may be " Galliard " ; the boring samples 
are too broken up to judge. If, however, wc group No. 12 
with 13, 14, and 15, it would give as shales 177 feet, and sand- 
rock with shale parting 117 feet. The most remarkable coin- 
cidence is, however, the total depth ; the Survey calculations 
are 421 feet, our section to the base of No. 15 gives us 426 feet. 
This of course is a mere coincidence, but it is remarkable and 
interesting. 
As to the absence of water in quantity, and its low level 
of 159 feet from the surface, the works where the bore was sunk 
are about on the 700 feet datum level ; the base of Sandrock, 
No. 15, would therefore be about 270 feet above sea level, and 
the water surface about 540 feet. The outcrop of this Sand- 
rock in Luddenden Dean would be at an elevation, roughly, 
of 650 to 700 feet, so that unless the rocks were very heavily 
charged with water, an unlikely assumption, considering the 
severe slopes of Warley and Luddenden, and the amount of 
drainage to the stream in the valley, the water level could not 
be expected to rise much higher ; and when this rock, No. 15, 
did not furnish a supply, it was considered useless to go lower, 
or at least highly unlikely that any lower supply could be ob- 
tained to be of sufficiently economical service. 
Messrs. Ramsden commenced boring operations in October, 
1901, and finished in June, 1902 ; their object being attained 
in securing a fairly satisfactory increase of water supply. The 
boring was commenced at the bottom of an existing well situate 
on their premises in St. John's Lane. The well is 50 feet deep 
and 6 feet in diameter, the surface being about on the 500 
feet datum level. A 10^ inches diamond core bore, giving a
