GEOLOGY. — The Geological Section will be officially represented by 
its Sscretaries, Messrs. John Holmes, Edwin Hawkesworth and C. 
Bradshaw, F.G.S. 
Mr. Hawkesworth writes:— The district may not be so attractive to the 
majority of Geologists as some visited by the Union, bat it presents many in- 
teresting features. There is the classic section by the river side, beneath the 
Castle at Knaresborough, showing so clearly the Magnesian Limestone resting 
on the Millstone Grit (third grit), the surface of which is undulating, and the 
base of the limestone containing many quartz pebbles, these, apart from the 
fact of the limestone resting on the Coal Measures further south, proving the 
unconformability of the two formations The junction may be still better seen a 
little lower down the valley, especially looking from the opposite side, and a beau- 
tiful walk by the river may be continued to Grimbalds Crag, where there is a 
remnant of limestone capping the grit. The walk may be further continued to 
Plumpton. where the curiously weathered red grit of that name is well worth 
seeing. This grit was called New Red Sandstone by the older geologists, but it 
is now definitely ascribed to the Millstone (^rit series, about the same horizon as 
the famous Brimham Rocks. The Lower Magnesian Limestone can be examined 
in the Town Lime Quarries,— it is quite unfossiliferous, but contains a large 
number of cavities, many of which are lined with beautiful crystals of dolomite. 
The Nidd, and its valley, suggest some problems of interest, and those present 
may discuss why the river should cut right through the Permian escarpment. 
The valley at Knaresborough is a U-shaped gorge, typical of glacial erosion, and 
the district affords other examples of the results of glacial action, such as stream 
diversion, lakes, and deserted channels, that of Cayton Ciill, formerly an inlet 
channel, being worthy of special mention, .\nother excursion may be made up 
the valley, in the course of which, on the way to Nidd Bridge, the axis of the
