examine the interesting clints or bare limestone tables which are 
so characteristic a feature of this district. Then the Professor 
pointed out the succession of Yoredale limestones and sandstones 
which make up the main of the higher part of Ingleborough, 
surmounted by the Upper Scar Limestone, over which comes the 
cap of Millstone Grit which forms the summit. After the summit 
had been reached the leader pointed out the evidences of the 
ancient encampment, which consisted of millstone grit flags 
set on end, against which smaller blocks had been heaped up. 
Refreshment having been obtained at an excellent spring at the 
base of the Millstone Grit, the downward journey, on the east 
side, was utilised for the examination of the limestone, containing 
Producta gigantea var. latissima, and an attempt was made to 
discover whether there was any specific difference between this 
variety and tlie normal form found at a lower level. After a 
short sojourn at Gaping Gill Hole, the return journey was taken 
by Trowgill to Clapham. 
After dinner at the New Hotel, Clapham, the general meeting 
was held under the presidency of Professor Hughes. After the 
reading of the minutes, the following new members were elected: — 
Messrs. Chas. T. Whitmell (Leeds), Hymas (Ripon), Edgar D. 
Wellburn (Sowerby Bridge), W. Robinson (Sedburgh), W. Stewart 
(Wakefield), and J. W. Tate (Ingleton). Professor Hughes then 
delivered an address on the geology of the district, which 
he characterised as one of the most interesting in England. 
As one stood on the top of Ingleborough you could see the 
relics of one of the great ancient sea-plains. Dotted all round 
were hills of 2,000 ft. or thereabouts, the height of w^hich was 
not determined by the hard capping band of Millstone Grit, for 
on the Howgill Fells the same general level was maintained, 
and right on to the Lake District. There you came on to a 
sudden uplift to 3,000 feet, the relics of a much older sea- 
plain. Also at the base of the Carboniferous Limestone all over 
the district there lay Cambrian and Silurian beds, which, though 
folded and uplifted, were cut off clearly to form a plain on which 
the Mountain Limestone had been deposited. These plains were
