Yorkshire Naturalists’ Union: Annual Report, 1910. 63 
GEOLOGICAL SECTION. 
Report for Geological Section. Mr. Cosmo Johns writes :— 
The excursions have been well attended by members of the Section, 
except on one occasion, and one or more of the sectional officers 
have been present. The excursion to Middleton-in-Teesdale 
afforded a welcome opportunity for renewing acquaintance with 
a classic region. A carefully worked out programme, for which 
Messrs. Burton and Robinson were responsible, was carried out. 
The igneous rocks, Carboniferous Limestone, Drift, and the 
interesting but puzzling sections of pre-Carboniferous rocks at 
the Pencil mills were visited. 
Malham once more attracted a good number. The 
Craven Faults, with the evidence for a reading of the structure 
different to that given by the published Survey Map of the dis- 
trict; the little known Black Hill, an outlier of Yoredales with 
a capping of Millstone Grit, and the exposure of the ancient floor 
on which Carboniferous Rocks were laid down, received attention. 
Easington afforded an opportunity for visiting drift deposits 
of Holderness, and thus of renewing acquaintance with the ever- 
changing sections of boulder clay. Under the guidance of 
Messrs. Stather and Sheppard, much of the new evidence was 
reviewed. 
Kirby Moorside did not provide many geological opportunities, 
but at Scunthorpe the wonderfully interesting Liassic Sections 
afforded by the excavations for Ironstone, the re-distributed drift 
and the overlying blown’ sand received careful attention, and the 
thanks of the section is due to Mr. A. C. Dalton, whose local 
knowledge was placed unreservedly at their service. 
The chief obstacle to the prosecution of work by the section is 
the shortness of time available during the excursions. A week-end 
with two clear days for field work represents the minimum time 
in which any useful programme can be carried out, and it is really 
only when four clear days are available, such as occurs during the 
Whit week and August Bank Holiday meetings, that a reasonably 
complete examination of a particular district can be made. 
It cannot be too strongly urged that the feature of such 
visits can only be to review work that has been or is being done, 
and to suggest the lines for future work. The real additions to 
knowledge follow such visits, and are not necessarily made 
during them. 
There are still many directions towards which the section 
might profitably direct its energies. In the Coal Measure districts 
a rich harvest awaits conscientious workers in the many clay 
pits or natural sections ; in Yorkshire this representing an almost 
unworked field. Careful work along the escarpment of the 
Permian Rocks from Conisborough northward, so as to establish 
a definite correlation with the typical sub-divisions of Durham,
