after dark will give larvae of many species of heath -feeding Lepidoptera, 
e.g. Noctua sobrina, N. festiva, Agrotis agathina, Scodiona belgiaria. Birch 
trunks should be searched for Lobophora carpinata and Cymatophora 
flavicornis ; grass-tufts near Galium saxatile for Laventia multistrigaria , 
while beating pines will give larvae of Ellopia prosapiaria, Thera variata 
and T.firmata. 
THE DISTRICT AND ITS GEOLOGY.— Mr. C. H. Wilson writes : 
Robin Hood’s Bay is considered by many people to be the most picturesque 
bay on the East Coast of England. It forms an amphitheatre about five 
miles in diameter, dished, like an enormous bowl, out of the hillside, the 
top of which, in some places, reaches the 700 ft. contour line. From the 
brim, looking down the steep sides of the slope, to the sea at the bottom, 
the prospect is delightful to the nature lover at all times of the year. Most 
of the land in the immediate district is cultivated, but moorlands invest 
a great part of the bay. Several deep wooded ravines, with waterfalls, 
form a very pleasing contrast to the pasture land. The slope on the southern 
side is somewhat marred by shale dumps, and take one back in time to the 
days when alum was produced from the Lias strata. Nature has not yet 
quite healed her wounds. There is also at this spot a quarry, perhaps 
better described as a clay escarpment, where the fossil-hunter may gain a 
rich harvest, but, unfortunately, most of his specimens are likely to be 
incomplete. Geologically the coast is one of the most productive districts 
in the world, ammonites, belemnites, and bivales predominating. The 
Geology is best described in Kendall and Wroot’s ‘ Geology of Yorkshire,’ 
and the other publications to which reference is made above should be 
consulted. 
VERTEBRATE ZOOLOGY.— Mr. T. N. Roberts writes : Many 
interesting species of birds may be observed in the district adjacent to Robin 
Hood’s Bay. 
On the sea and the cliffs both north and south of the bay may be seen 
large numbers of Herring Gulls ; the Comorant nests in suitable places 
at the Peak ; Jackdaws and Rock Doves inhabit the precipitous portions, 
while an odd Kestrel may be seen. The Fulmar has in recent years 
established itself as a nesting species and may be seen in large numbers ; 
to see this bird on the wing is a sight well worth a visit to this part of the 
coast. 
In the woods in the vicinity the Tawny Owl, Green Woodpecker, Ring 
Dove and Woodcock may be observed as may also the Carrion Crow and 
Magpie, while one or two pairs of Long-Eared Owls may be found in the 
fir plantations. 
Inland on the Moors may be seen the Wheatear, Curlew, Golden Plover 
and the Merlin, as may also the Ring Ouzel and the Stone-Chat. The 
Dipper can be found on all the streams and several pairs of Grey Wagtails 
are most likely to be found. Lapwings are plentiful on every field, along 
with many other common species. On some moorland ponds within a 
few miles may be found a colony of Blackheaded Gulls, where Teal have 
nested in recent years.. 
Easter may be early for the summer visitors, but Chiff-Chaff, Willow 
Wren and others may have arrived. 
A GENERAL MEETING will be held at Headquarters on Monday 
at 6 p.m. for the election of new members, and to received reports from 
Section Leaders. 
Day visitors wishing to take a meal at Headquarters should notify the 
Proprietor on arrival in the morning. Full particulars of the routes, if 
different from those scheduled, will be left at Headquarters before starting 
out each morning. 
It is particularly requested that reports of this meeting should be 
forwarded to the Hon. Secretary without delay.
