BOOKS AND MAPS.— The whole area is included in Sheets 40 and 50 
(formerly 97 N.W. and 97 S.W.) of the one-inch Survey. Both Sheets are to be 
had geologically coloured. Vol. H. of Phillip's classical work on the " (ieology 
of Yorkshire," should be consulted for detailed particulars, diagrams and sections 
of the " Yoredale Series of Rocks " of the district, Phillips having adopted the 
upper end of VVensleydale as a- general standard of reference for this interesting 
group. Dr. Percival compiled a Flora of Wensleydale for the " Naturalist " in 
1888, afterwards separately published. Baker's " North Yorkshire " contains 
geological and botanical information. A list of Wensleydale Birds, by E. 
•Chapman, will be found in the "Naturalist" f(3r 1886. Mr. W. Dennison 
Roebuck gave a resume of his Field Notes on Conchology in the same publica- 
tion for November, 1882, VIII., 52 — 55. Canon Whaley's History of Askrigg 
and Bainbridge may be ussfully referred to, and so also may Mr. Speight's 
History of " Richmondshire." The Excursion Circulars of the Meeting at 
Hawes in June. 1884, and at Askrigg. June, 1905 (No. 187). " The Fungus Flora 
■of Yorkshire," Massee and Crossland (Trans. Y.N.U., parts 28 and 32) ; " The 
Birds of Yorkshire," by T. H. Nelson. 
HEADQUARTERS— King's Head, at Askrigg. 1;^ miles from Bainbridge, 
where acc jmmodation is very limited. The terms are 7/C a day, for bed, break- 
fast, sandwiches for lunch, and dihner, including attendance. Rooms should be 
ordered without delay, or disappointment may ensue, the district being a favourite 
one. 
ROUTES. — On arrival of 11-14 train at Askrigg members will proceed on 
the following routes: — 
Route 1. Addlebrough to High Force and thence to Park Scarr. Return 
by River Bain. 
Route 2. Mill Gill, Vi^hitfield Gill and Skell Gill. Late arrivals are 
advised to take this the shorter route. 
Members are particularly warned to avoid meadow lind and not to disturb 
game in the woods or grounds about Semmerwater. 
Mr, J. Hartshorn, Mr. W. Balderston, of Yore Bridge House, and Mr J J. 
G. Lodge, who are acquainted with- the district, have kindly promised to be 
present at the excursion. , '

GEOLOGY. — The Geological Section will be officially represented by 
one of its Secretaries, Mr. John Holmes, Mr. W. Robinson and Mr. Wm. 
Home. Mr. W. Robinson writes:— The Upper End of Wensleydale was 
adopted by Phillips as a standard of reference to the Yoredale Rocks of the 
Carboniferous System. These rocks consist in the neighbourhood of Bainbridge 
of the Great Scar Limestone and of five considerable belts of limestone inter- 
statified with shales, flagstones and grits. 
Bainbridge lies on the Great Scar Limestone. Thence to the top of 
'Addlebrough, near to, are passed the Hardrow Limestone, the Simonstone 
Limestone, the Middle Limestone and the Underset Limestone, which forms an 
escarpment or mural precipice on the top. 
Towards the East these limestone beds approximate continually nearer to 
each other and the beds grow thinner and ultimately are completely extinguished. 
Interposed between them here are masses of Sandstone with shales and 
Some thin beds of impure limestone, the space between the underset at the top 
.of Addlebrough and the bed underneath being here as much as 280 feet. 
Though published nearly 80 years ago the best account of the Geology of 
:-this district is still to be found in Part 2 of " Phillip's Illustrations of the 
• Geology of Yorkshire," on which the foregoing observations are based. 
But students wishful to study these rocks in detail should refer to the 
admirable paper by Professor Garwood in Part 4 of Vol. VIII of the Quarterly 
, Journal of the Geological Society on the Lower Carboniferous succession in the 
North West of England. The rocks are there dealt with zonally on lines 
similar to that adopted by Professor Vaughan in the Bristol area. By 
'identifying the fossils named in the zones and sub-zones in Professor Garwood's 
■paper and tracing the faunal horizons through the intermediate districts it 
would be possible to correlate the limestone rocks of Wensleydale with the 
■ Pendlesides on the South West. ■ Mt. Cosmo Johns devoted mucn time, to that 
interesting work. ' \ '•• _ • ' . . 
■ " As an alternate to the limestones, the Vallfey, iti which the River Bain flows 
from Semmerwater, may be followed to inspect the multitudihous'evldence there 
visible of the effects of the Glacial epoch.
