SHEPPARD : INTER-GLACIAL GRAVELS OF HOLDERNESS. 
More recently the late Professor Carvill Lewis visited these 
gravelS; and, though he stated that there was a lack of evidence in 
support of an inter-glacial period, he expressed the opinion that 
" Kelsey Hill is not a mound, and has not the aspect of a moraine," '' 
and certainly the hills in question do not present the characteristic 
appearance so lucidly explained to some of us at a meeting of the 
Glacialists' Association, held at Birmingham last December (1894), 
when Mr. P. F. Kendall gave us the benefit of his work on the York 
Moraines.f lu the " Geology of Holderness " it is statedj " About 
half-a-mile from Kelsey Hill, in the north-east continuation of the 
same gravel, there are two small pits " {i.e. in 1885). 
The object of the present paper is to describe the sections 
exposed by more recent excavations, and to discuss by the aid of 
this new information the views expressed by earlier observers. 
The most northerly exposure is now entirely worked out. A 
small section showing current-bedded chalky gravel, with shells and 
foreign stones, capped by six feet of reddish boulder clay, was all 
that was visible last summer (1894). The frost and rain of the past 
winter, however, by causing a large mass of boulder clay to slip over 
the gravels, have entirely covered up the lower portion of the section, 
leaving only a slope of boulder clay visible. 
The other pit, locally known as the Burstwick Gravel Pit, has 
been steadily enlarging : the excavation of material for the light- 
house recently erected at Withernsea has greatly helped to give the 
section its present size. 
The Burstwick Hill is broader than those of the same range to 
the north and south, and it has a flat top The section is cut in 
from the eastern side of, and roughly at right angles to, the line of 
hills. 
The gravel here is very similar to that at Kelsey Hill, and 
displays a similar variability in different parts of the pit. Towards 
the western side it is mainly sand, with a tongue of boulder clay 
intercalated in it in a most remarkable manner (A 1). This boulder 
clay is of a very red colour, has a peculiar serpentine form, is not
