YORKSHIRE NATURALISTS AT ROBIN 
HOOD’S BAY. 
May 18th to 20th, 1907. 
Durinc Whit week-end (May 18-20) over forty members of the 
Yorkshire Naturalists’ Union stayed at Robin Hood’s Bay. 
This number was augmented on Bank Holiday, and a few 
remained longer. As has been the practice in recent years, 
the evenings were devoted to the reading of papers and 
discussions thereon, and in this way additional value and 
interest was added to the work accomplished during the 
field excursions. 
As might be expected from the nature of the district, and 
its geological traditions, the hammermen were predominent, 
and had an exceptional opportunity of examining the sections 
in the cliffs and in the quarries adjacent. These places have 
also long been known as haunts of interesting birds, which, on 
this excursion, were the means of attracting several camera 
and field-glass ornithologists ; the old-fashioned type—the egg 
collector pure and simple—is now almost as rare as are some 
of the birds he has all but exterminated. 
The numerous steep-sided, well-wooded ravines around ‘Bay 
Town’ proved irresistible to many besides the botanists, and 
the shore yielded shells and sea-weeds to those interested in 
marine fauna and flora, the last being an attraction not always 
present on our rambles. 
The geologists had the advantage of the leadership of Prof. 
P. F. Kendall, who was as familiar with the problems of ‘solid’ 
geology as with those of the glacial series, in connection with 
which latter his work in north-east Yorkshire is now so well 
known. 
On Saturday morning an early start was made, and the 
beach, scars, and cliffs between ‘Bay Town’ and Ravenscar 
were examined ; sections in the Lias, ‘ Dogger,’ and Estuarine 
Series being available. Particular attention was paid to the 
fault in the strata at the Peak. This yielded evidence that a 
movement in the earth’s crust was taking place during the 
deposition of the beds, the thickness of the layers of sandstone, 
etc., varying on each side of the fault. The continuance of the 
fault seawards and the way it bifurcates was easily seen on the 
scars. The area traversed was a favourite hunting-ground for 
geological specimens, and several were secured. A fitting
