secretary's report, 1900. 
The work of the Society during the past twelve months has 
been of exceptional interest, the General Meetings and Field 
Excursions have been well attended by the members, and by 
advancing beyond our ordinary boundaries opportunities for 
independent investigation have been taken advantage of, and 
valuable knowledge of several Yorkshire geological problems has 
been gained. In our May excursion to the borders of Lancashire 
much information was gained by the study of knoll-reefs, which 
serves to make clearer the problem of the Cracoe knolls, whilst 
during the visit to the Cheviots the local source of large numbers 
of the East Riding drift boulders was made certain, and another 
chapter in the history of the great ice-sheets which presserl in 
on our coast during the Glacial period was disclosed by the fine 
moraines and overflow valleys of the eastern slopes of Cheviot. 
Our Yorkshire geology is a part of a larger history, and 
frequently it is only by going beyond the bounds of our county 
that the requisite evidence can be obtained for settling many 
important points of home geology. 
The First General Meeting and Field Excursion were held 
at Clitheroe, on Friday and Saturday, May 25th and 26th, 
under the presidency and leadership of Mr. Joseph Lomas, 
F.G.S., of Birkenhead. The district to be visited included 
Pendle Hill, the knoll-reefs of the Clitheroe valley, and the 
gorge of the Hodder at Whitewell. 
On the first day wagonettes took the party over Waddington 
Fell to Kewton-in-Bowland, and thence along the picturesque 
valley of the Hodder to Whitewell. Several good examples of 
knoll-reefs were noticed on the way. At Whitewell a short 
time was spent in examining the shales in a little clough opposite 
the bridge, to which the attention of the members had been 
directed by Dr. Wheelton Hind, of Stoke-on-Trent. These shales 
were found to contain a very interesting fauna, being crowded 
with delicate polyzoa, and containing small trilobites and cypris
