a ‘wash-out.’ In the cutting, and also in the debris, fossils in 
profusion were found. 
Glacial evidence was forthcoming in the shape of grooved 
blocks of stone in situ, recently uncovered, and also in many 
blocks which have been moved by a recent landslip. 
The sand quarry at Ayton was visited, and many marine 
shells—some entire, but most in fragments—were obtained. 
Far-travelled erratics in abundance were also noticed. 
Probably, however, the most extraordinary sight of the 
excursion was the enormous landslide on Roseberry Topping. 
The conical hill has split across the top as if it had been 
sliced by a knife, and the whole of the west face has bodily 
moved down the slope. The information given was that the 
slipping first commenced at the foot. The surface soil appar- 
ently rested on a stratum of soft yellow clay, and this again 
on a rock which had probably been smoothed by the passage 
of the ice sheet across the face of the hill. The smooth rock 
provided an excellent sliding plane, and the soft wet yellow 
clay a good lubricant for the surface soil and rock debris to 
slide to a lower level, and thus uncover the sandstone cap. 
This was found to rest on soft friable shales in which the plant 
remains were discovered. Once exposed to the weather the 
shales quickly disintegrated and left the hard cap undermined. 
As the process went on detached pieces. of rock fell on the 
sliding mass and hastened its movement. The bottom of the 
slide now presents a perpendicular face of six to twelve feet 
high, and it is doubtful if it has come to rest.

Photographic Supplement to Stanford's Geological Atlas of Great 
Britain and Ireland. By Horace B. Woodward, F.R.S., with the co-opera- 
tion of Miss Hilda D. Sharpe, 113 pp., 4s. This is a collection of over a 
hundred reproductions of photographs of the principal geological features 
of the British {fsles, and forms a fitting companion to the Geological 
Atlas which has already been referred to in these columns. There are two 
illustrations to a page, and each is accompanied by ten or a dozen lines of 
descriptive matter. The illustrations appear to have been chosen with 
care, though it came as a mild shock to us to find that Yorkshire was 
represented by one poor photograph of the rocks near Filey Brig, while a 
book of British geological photographs without a single print from the 
well-known camera of Mr. Godfrey Bingley seems almost unbelievable. 
A Dictionary of English and Folk-Names of British Birds. By H. Kirke 
Swann, London: Witherby and Co., 1913, pp. xli+266, Ios, net. 
This extraordinarily useful book contains about five thousand names of 
British Birds, including (1) English Book-names, culled from past authors, 
from the earliest series in Turner on Birds (1544), Merrett’s Pinax (1666), 
Charleton’s Onomasticon Zoicon (1668), and Willughby & Ray’s Ornitho- 
logy (1678), as well as General English Literature, to Albin, Edwards, 
Pennant, Bewick, Mantagu, Latham, Macgillivray, Yarrell, etc., etc. ; 
(2) Accepted names of the present day, with their history and first usage ; 
(3) Provincial, Local, and Dialect Names, with their locality and meaning ; 
(4) Welsh, Gaelic, Cornish and Irish names; (5) Folk-Lore, Weather-Lore, 
Legends, etc., connected with each bird. | We have tried hard to find that 
some rare or little known name was omitted in this volume, without 
success,
