^OOKS AND MAPS. — The district for investigation is included in 
Sheet 158 of the six-inch Map, and Sheet <)-'5 N E. (new series, Sheet 63), of the 
one-inch Ordnance Map, which is also published geologically coloured. 
Reference may be made to J. F. Robinson's " Flora of the East Riding of 
Yorkshire" ; T. H. Nelson's " Birds of Yorkshire" (1907) ; " The Fungus Flora 
of Yorkshire," Massee and Crossland (Trans. Y.N.U. Parts 28 and 32) ; and The 
British Association Handbook, York Meeting, 1906. 
HEADQUARTERS.— Bay Horse Inn, Stamford Bridge, near the 
Station. 
DISTRICT.-Mr. S. H. Smith writes :— The district to be traversed is 
situated eight miles North East from York, and is but a short distance from the 
foot of the well-known Wold Hill of Ciarrowby. The village is upon the East 
bank of the River Derwent, and its name recalls the famous battle fought there 
in September, 1066 The route to be followed by the members of the Union will 
be by pleasant stretches of water fringed v,ith alders, a succession of delightful 
pictures culmmating in a charming scene at the Lock House and weir. On the 
left stands Aldby Park, famous as the residence of an old Yorkshire family, the 
Darley's, and as a Roman Station, and of being the site of a Royal Villa belong- 
ing to the Kings of Northumbria. Proceeding through the noble park at Aldby 
the path leads through a succession of sylvan groves that hold rich treasures 
according to the desire of the naturalist, and ultimately the party will emerge 
upon the road leading through the well-known Buttercrambe Woods, back to 
headcjuarters. 
ROUTES.— On the arrival of the trains at Stamford Bridge, due from 
Hull at 9-16 a.m., and from York at 9-27 a.m., the party will proceed under the 
guidance of Mr. S. H. Smith, by way of the right bank of the River Derwent to 
13uttercrambe Bridge, then through Aldby Park, returning to headquarters 
through Buttercrambe Woods. Distance about 7 miles. The Geologists will 
select their own route. 
PERMISSION to visit Aldby Park has kindly been granted by Major 
W. H Collins. 
GEOLOGY. — The Geological Section will be officially represented by 
Mr. 1. W. Stather, F.G.S., who writes: 
The Vale of York is a very broad and ancient valley excavated in the soft 
sandstones and marls of the Permian and Triasic series, which in the neighbour- 
hood of Stamford Bridge are entirely covered by superficial deposits, consisting 
for the most part of Glacial accumulations. 
As Prof. Kendall has many times pointed out, there are in this district, two 
distinct terminal moraines which mark phases in the retreat, or possibly advance, 
of the Vale of York glacier. They extend as perfect and nearly parallel 
crescentic mounds nearly from the foot of the Wolds, round to the outcrop of the 
Jklagnesian Limestone. 
The more southerly of these moraines can be examined at High Catton, 
near Stamford Bridge, where excellent sections may be seen in a series of gravel 
pits Amongst the morainic material of the Vale of York many rocks from far 
distant localities have been recognised, such as Granites from Galloway, 
Brockram and the Dufton " Granite " from the Vale of Eden, and various 
igneous rocks from the Lake District, such as the Diorite of Carrock Fell, the 
Quartz Porphyry of Threlkeld, and the well-known Granite of Shap Fell. 
The Whin Sill is also well represented. 
BOTANY.— The Botanical Section will be officially represented by Dr. 
T. W. Woodhead, F.L.S. 
Flowering Plants.— Mr. H. J. Wilkinson writes:— By the right side 
of the River Derwent, and in Buttercrambe Woods and Aldby Park, V.C. N.E. 
62, some interesting plants have been recorded : — Thalictrum flavum, Corydalis 
clavicidata, Nastuytium sylvestris, N. palustris, Barbarca vulguaris, Stellaria aquatica, 
S. palustris, Hypericum clodes, Geum rivale, Drosera rotundifolia, Valeriana officinalis,
