Archaeologists who will also find some objects of interest in Kildale Church. 
Very extensive Fir Woods clothe the upper slopes of the hills both on the 
Kildale and Lonsdale Slopes, and the views from the higher parts over the 
Cleveland Hills to the East, and the plain of York to the West, are fine and very 
extensive. Ample scope is afforded for the energies of the members of every 
section. 
ROUTES.— Geologists. Leader, Mr. J. J. Burton, F.G.S. 
It is expected that the Yorkshire Geological Society, whose Headquarters 
are to be at Saltburn, will join the geological members of the Y.N U. 
Saturday will be spent chiefly in examining the Whin Dyke and the 
physical changes which it has produced in the accessible lias shales through 
which it has forced it way. 
Several glacial features will be pointed out, and an examination of exposures 
in the lias and also in the estuarines, of the inferior oolite will be made so far as 
time will permit. 
Monday will be devoted chiefly to an examination of Roseberry Topping, 
its ironstone seams, the huge landslide which has taken place, and the wonderful 
exposure of plant remains. 
If desired an opportunity will be given any of the members to enter the 
Mine on previous notice being given to the Divisional Secretary, to enable him 
to make the necessary arrangements. 
Botanists and other Sections. Leader, Mr.T.A.Lofthouse, A.K LB.A., 
F.E.S. 
On Saturday! on the arrival of the train due at Great Ayton at 11-11 
a.m., the party will visit the Airyholme Woods and Quarries a little distance 
from Ayton Station, and work the ground in this neighbourhood until the 
arrival of the train due at 2-34 from Middlesbrough. After which they will 
proceed to Gribdalegate, into Lonsdale, and Lonsdale Woods to Kildale, about 
6 miles. Trains leave Kildale for Ayton, Stokesley and Middlesbrough at G-40 
and 8-56. 
On Monday, meet at Ayton Station at 9 o'clock on arrival of train from 
Stokesley and Battersby, etc. Walk from Ayton to Kildale by upper path (3 
miles), joining main party at Kildale at 11-30, and then proceed through 
Kildale Woods, Easby Woods to Easby and Great Ayton Station, distance 
4 to 5 miles. An alternative route could be taken from Kildale Woods 
across the moors by Captain Cook's Monument to Great Ayton, by those who 
prefer to be on high ground. 
PERMISSION to visit their estates and properties has been obtained 
from the owners of Airyholme Estate, the Roseberry and Cockshaw Mines, R. 
B. Turton, Esq., J. J. Emerson, Esq., and J. B. Hodgkin, Esq., and the Grib- 
dale Mining Co., Ltd., 
GEOLOGY. — The Geological Section will be officially represented by one 
of its Secretaries, Mr. John Holmes, and Mr. J. J. Burton, F.G.S. 
Mr. Burton, writes: — Great Ayton lies in the drift covered area of the 
Cleveland plain, just below the lias escarpment of the moors of North Cleveland. 
The escarpment is generally capped by the inferior oolite, and exposures of both 
the lias and the oohte are numerous and easily accessible 
Dominating the village is Cliff Rigg ; a hog-back of whinstone which has 
resisted denudation much more than the softer lias shales through which it 
rises, causing a very striking feature in the landscape. 
The Dyke after pursuing a long course from the W., swells out to a great 
thickness at Great Ayton and then thins away until it dies out near Robin 
Hood's Bay. Dr. J. J. Harris Teall, gives it as an augite-andesite of Tertiary 
age with a sp. g. of 2.77 and an analysis of 57% to 59% of Silica. The rocks 
on each side of the dyke have had their planes of cleavage considerably altered 
for some distance. 
Another dominating feature of the district is Roseberry Topping — a conical 
hill over 1,000 feet in height, formed in the lias but having a cap of hard 
oolitic sandstone which has preserved it from denudation. This hill has 
recently split across the top and one steep side, which appears to have been in a 
state of unstable equilibrium, has fallen away, with some extraordinary results. 
This splitting of the top has exposed to view a very remarkable plantbed pre- 
viously known to exist but difficult to locate. The surrounding escarpments 
also contain plant remains in vast quantities
