Here Goni&tites, Aviculopecten, a.nd Posidoniella were collected. 
These shales lie between the Kinder Scout and Second Grits, 
and are obviously of marine origin, pointing to a period of salt 
water (outer estuarine) conditions, an episode in the history 
of the great Millstone Grit delta. 
Pendle Water flows from the slopes of Pendle Hill and is 
subject to sudden and destructive floods, which have necessitated 
the erection of considerable training walls. 
Remains of plants {Calamites) were also found in these 
shales and many of the goniatites were observed to contain 
small quantities of petroleum. Some of the members visited 
the picturesque Hall at Roughlea, the house mentioned by Ains- 
wortli in " The Lancashire Witches." 
Following the stream downwards, a charming valley was 
traversed, and Mr. Wilmore pointed out many matters of interest 
in connection with the denuding action of the stream, and 
was able in one case to indicate the amount of material which 
had been removed during the last 20 years, and to show the two 
ends of a footpath, the middle part of which has now disappeared. 
The observations made during the early part of the day in 
the railway cutting at Salterforth raised matters of such interest 
that it was decided to cp.ncel Tuesday's programme, and to 
visit Winterburn, near Skipton, where beds of similar age are 
exposed, in the hope that some further light might be thrown 
upon the question. 
On Monday evening there was an interesting exhibition of 
fossils from the Carboniferous rocks of the district by Mr. Peter 
Whalley and other local collectors. 
Mr. Whalley 's collection included a large number of fossil 
plants from the Coal Measures and a unique collection from 
the MUstone Grit Shales near Grassington. 
On the projDosition of Professor Kendall and Mr. Lomas 
a vote of thanks was passed to the exhibitors. 
On Tuesday morning the party proceeded by train to 
Skipton, and thence drove to Winterburn Valley. Here they 
succeeded in finding a very good sequence of rocks and many 
interesting and well-preserved fossils.
