SECRETARY S REPORT. 
Mr. Fox-Strangways had shown that the Yale of Pickering was 
blocked by the ice and became a great lake. Similar reason- 
ing, said Mr. Kendall, would require an extra morainic lake in 
Eskdale, in Kildale, and at many other jDoints along the edge of 
the ice. Evidences of these lakes were found all round the 
Cleveland Hills. The overflows were over soft rocks and the 
lake-levels consequently fell too rapidly for the formation of 
marked beaches, but the presence of numerous overflow- valleys 
revealed the histor}^ of the glacial lakes and their varying 
drainage in a very interesting manner. These papers were fol- 
lowed by a discussion, in which Messrs. F. F. Walton, J. W. 
Stather, E. Hawkes worth, and W. L. Carter took part, the readers 
of the papers responding. A vote of thanks was passed to the 
Chairman, the Leader, and the Readers of Papers, and Mr. Turton 
briefl}^ replied. 
The second day's Field Excursion was taken by wagonette 
to Great Ay ton, where a visit was paid, under the Rev. John 
Hawell's guidance, to tlie workings in the Cleveland dyke. 
These are now carried some distance beneath the surface by 
mining operations giving an interesting series of exposures. 
After searching the old ironstone spoil heaps for fossils, and 
examining a gravel pit, in w^hich shell fragments were found, 
the ascent of Roseberry Topping w^as made and the extensive 
view admired. Thence a detour was made over Ayton Moor, 
on w-hich some interesting barrows and entrenchments were 
seen, to Lonsdale, aud thence through the wood to Kildale. 
Near Kildale Railway Station a deposit of shell-marl of post- 
glacial age, full of shells, was examined. In the overlying peat 
deposit antlers of the reindeer have been found. The path 
through Kildale Wood was then taken to Dundale Beck, and 
the return journey made by wagonette to Stokesley. 
In connection with the Yorkshire Naturalists' L^nion Excur- 
sion on Bank Holiday Monday, an extension of this geological 
route was arranged. The party, led by the Rev. John Hawell, 
ascended Hasty Bank, and examined a good exposure of Middle 
Lias. The watershed was then crossed to view a pretty little
