believing that a large proportion of the unexhausted mineral 
wealth of this field underlies Lincolnshire west of the Wolds. 
This view had been accepted by the recent Royal Commission 
on Coal Supplies, and had been included by them in the estimate 
recently presented to Parliament. In this view an area of up- 
wards of 1,000 square miles of Lincolnshire is underlaid by 
coal measures at workable depths. The time might not be far 
distant when Lincolnshire would be the great coal-producing 
area of England. The wold region of Lincolnshire is largety 
covered with glacial deposits, and these deposits actually cross 
the Wolds in the middle region. 
On Monday the party took train for Withcall, and Prof. 
Kendall pointed out the pink band in the Lower Chalk there^ 
remarking that it had been suggested that the colour was due 
to the oxidation of glauconite. He was of opinion that the 
marl bands were due to solution of a considerable portion of 
the chalk, the fossils in the marl being filled with white chalk 
and not with marl. 
There is a particularl}" fine section of the Red Chalk at the 
western end of Withcall tunnel, through and over which the 
party was conducted, and here were obtained Terebratula hi- 
plicata and the characteristic Belemnites minimus. At Donning- 
ton brick-pit, where the Tealby Clay is exposed, Professor Kendall 
said this was the zone of Belemnites jaculum, but that fossil 
had not been found there, though he had obtained the large 
Crioceras which they got at Speeton. Exogyra sinuata, which 
is characteristic, the remains of a shrimp-like animal {Meyeria)^ 
and Pecten cinctus were found, and then the party proceeded 
to a pit in the Spilsby sandstone showdng the characteristics 
alluded to in Professor Kendall's address. 
The next rendezvous was the Benniworth Haven cutting, 
where the engineer of the Great Northern Railway had kindly 
caused the Claxby ironstone, which overlies the Spilsby sand- 
stone, to be exposed. This bed is exceptionally rich in fossils, 
and was, in fact, the main object of the excursion. It contains 
curious oolitic grains of ironstone, lime having been exchanged 
for iron, and the predominant fossils were beautiful specimens of
