would probably give slightly different results. Small and un- 
important lenticular or wedge-like beds of shale part the sand- 
rocks here and there, and, similarly, shales have minor rock- 
bands within their mass which do not affect the more general 
divisions. Again, clayey or argillaceous shales may become 
more sandy or arenaceous, and ])ass without perceptible break 
into sandrock, or vice versa, so that it is frequently difficult 
to mark any clear line of division, or to decide the exact char- 
acter or definition of the rock. 
My object was to note the changes as clearly as I could, 
and to correlate each ])ortion of the sections where possible 
with its position in the series. 
Messrs. Ward's bore was sunk in 1898-9; their premises 
(the West End Dyeworks) are a little to the east of Queen's 
Road, and about midway from either end. 
The\^ had an existing well. 6 feet in diameter, sunk to a 
depth of 131 feet, from which they obtained a good supply of 
water, until the deep cutting for the High Level Railway across 
the dip slope higher up intercepted and diminished the amount 
available, and boiing was undertaken in the hope of tapping 
supplies from lower beds. 
The existing well tapped water held by the shales underh^ing 
the Rough Rock and its accompanying flagstones at the base — • 
the gather ng ground for this water being the higher land ex- 
tending towards High Road Well and Mount Tabor. 
An 11 J inches chisel bore was commenced at the bottom 
of the existing well, 131 feet from the surface ; this was carried 
down for 276 feet, and a 9 J inch bore for a further 101 feet, 
at which depth. 508 feet from the surface, operations ceased. 
The samples of rocks preserved were, of course, broken 
very fine by the boring chisel, and are consequently only of use 
lithologically, any palaeontological traces being quite unrecog- 
nisable. 
The following is a slightly abridged record of the rocks 
passed through : —
