BOOKS AN D M APS.— The whole of the district is comprised in Sheets 
87 S.E and 87 N.E. for Geologists, and Sheets 79 S.W. and 88 N.W. for 
Botanists, etc., of the one inch Ordnance Map which may be obtained geologi- 
cally^coloured. Reference may also be made to Lankester's " Account of Askern 
and its Mineral Springs " (1842), which contains a sketch of its Geology (pp. 34 — 
r)0, with coloured mip). Botany (pp. 50—57), and Zoology (pp. 54—72) ; also 
Davis and Lee's " West Yorkshire " ; F. A. Lee's " Flora of the West Riding" ; 
" The Birds of Yorkshire," by T. H. Nelson. M.B.O.U. ; and Y.N.U. Circulars 
for 20th May, 1886. 15th June. 1893 (No. 102), and 12th luly, 1906 (No. 190), and 
" The Naturalist " for 1893, (pp. 283—293). and for 1900"', (pp. 369—374). 
THE DISTRICT to be visited (writes Mr. H. H. Corbett, M.R.C.S.) by 
the general body of Naturalists, is on the low lying, flat and marshy land to the south 
of Askern. This was formerly all fen and shallow lakes, with slightly raised 
sandy islands interspersed. Much of it is now reclaimed, but there are still many 
thickets and swamps that retain the old marshland ^oraand fauna. 
HEADQUARTERS.— The Railway Hotel, Askern. 
ROUTES. — The whole district to be visited is within two miles of Askern, 
and efficient guides will be provided. The members should meet at the Railway 
Hotel, at 10-15 a.m. 
PERMISSION to visit their estates has been kindly granted by Mrs. F. 
Bacon Frank, Campsall, and Major C. Anne, Burghwaliis. 
GEOLOGY.— Mr. H. Culpin writes :— Askern, which by reason of its 
position on the Permian rocks overlooking the southern extension of the Vale of 
York, is at all titnes attractive to the Geologist, offers special inducements just 
now for a visit by our section. 
Near the township on the west, shafts are being sunk through the Permian 
rocks and the Coal measures to the Barnsley seam. Close by, the Permian 
Middle Marls are being excavated for clay for bricks. Permission has been 
kindly granted by Mr. Jos Humbleand Mr. W A. Wallis respectively, to examine 
the colliery tip and the clay pit. On the tip, which it is suggested should be 
visited first, ttjere will be opportunities of collecting fossils from (a) the beds at 
the base of the Lower Permian Limestone, and (b) the fresh water shell 
{Carhonicola) beds, the marine shell (Ptci'inopecten, Lingula, bands, the shales 
with fish remains, and the shales and sandstones with plant remains, of the Coal 
Measures. 
On the west of the tip is a cutting which shows the Upper Permian Lime- 
stone faulted against the Lower Limestone, .\fier inspecting this, the party will 
go to the clay pit, where marls with gypsum bands can be seen. 
A field path can then be taken to Campsall by those who desire to examine 
the quarries in the Lower Permian Limestone west of that place. 
The route suggested, however, is to proceed to Askern Mount, for the 
inspection of the tilted beds of Upper Permian Limestone of which it is formed. 
South-west of the Mount, and slightly below it, is a large gravel and sand pit. 
Here will be seen some 40 feet of coarse Permian Limestone gravel resting on 
what appear to be Triassic Sands. 
If time permits, a visit can then be paid to the low-lying lands on the south 
and east, which will be searched for glacial debris. On the way, the soil may be 
examined for sub-fossil shells {Limnwa, Planorbis, S^c), which, especially on the 
mole hills, shew themselves " white as a rain-washed bone." 
ARCHAEOLOGY.— Mr. H. H. Corbett writes :— On Sutton Common 
are some curious earthworks of Neolithic age, and Major Anne has kindly offered 
to have a section cut through one of these for the benefit of visitors interested in 
prehistoric archaeology.
