320 Yorkshire Naturalists at Stamford Bridge. 
Galerucella sagitlarie Gyll. very local and only recorded 
from Askham Bog. 
My thanks are due to Mr. W. E. Sharp, F.E.S., for kindly 
verifying several of the above species. 
GEOLOGY.—Mr. J. W. Stather, F.G.S., writes:—To anyone 
at all interested in glacial geology, the neighbourhood of Stam- 
ford Bridge is well worth a visit—for in this part of the Vale 
of York, the solid rocks are entirely hidden by huge masses of 
morainic material, left there by the glaciers of the Great Ice 
Age. 
The route chosen by the geologists was in the direction of 
High Catton, and the morainic character of the country 
traversed was quickly evident, both from the stones and boulders 
scattered on the fields and round about the farmsteads, and 
from the general features of the landscape. 
At High Catton the moraine is particularly well defined 
and has been quarried extensively in several places. In one of 
the pits a newly exposed section was seen, showing an exceed- 
ingly varied series of current-bedded sand and gravel. There 
was also, in the quarry, large heaps of recently excavated 
material consisting of well-rounded gravel and stones with 
here and there a large boulder. 
This was carefully examined and found to consist almost 
entirely of sandstones and limestones from Carboniferous 
sources. Not a single specimen of a local or a secondary rock 
was seen in this pit, but several specimens of Shap Granite and 
other far travelled igneous rocks were noted. Brockram from 
the Vale of Eden was also not uncommon. 
On the other hand, near High Catton Grange (one mile 
North-East of the above quarry) a small pit was examined, 
which, in addition to Carboniferous rocks, contained flints and 
pebbles of chalk, in abundance. 
Hearty thanks are due to Mr. Beedham, of Stamford Bridge, 
for help rendered the geologists in finding the sections, and for 
placing his horse and trap at their disposal.

Much unnecessary type seems to have been used in a contemporary
