In the discussion on “Notes on the Discovery of
Fossiliferous Old Red Sandstone in a Boring at Southall,
near Ealing,” by Ernest Proctor (communicated by Prof.
W. W. Watts), read before the Geological Society, Dr.
Strahan commented on the difficulty of the search for
fossils, which had been brought to so successful an issue by
the author. Dr. J. W. Evans congratulated the author on
the excellent use that he had made of the opportunity
afforded by the boring, which he only heard of by a happy
chance. He suggested that the law should require that full
information with regard to bores should be given to the
Geological Survey. He also alluded to the serious loss
geologists would suffer from the substitution of the chisel
drill for the diamond drill, which appeared probable in
borings for water and other purposes. Dr. H. Lapworth
said the suggestion of the previous speaker, that records of
all British borings should be lodged at the Geological
Survey office, was a good one ; but it would be necessary to
carry the matter a good deal further than this, if the
records were to be depended upon. The journals of borings
were kept by men who were often more or less uneducated
and possessed little or no knowledge of geology. In his
own experience he had found that such records were not
satisfactory. A Government control of boring records could
only be efficiently maintained if the Geological Survey were
notified before every boring was begun, in order that the
journal should be made under geological supervision. The
occasional use of the chisel in the process of boring was to
be regretted by geologists; but the borer himself was
concerned solely with the cost, and in cases where cores are
not demanded, the chisel, being cheaper in many materials
than the rotary processes, was often largely employed.
