it was thinner, and reposed on undisturbed Lias clay. There appears, 
however, to have been somewhere here a patch of re-formed clay and 
scratched stones, as my pupils J. B. Alexander and C. S. Taylor and 
I frequently found stones, apparently glaciated, in this pit, but could 
never find them in sitw. There used to be the appearance of the 
sand graduating into the ordinary drift.

Very near this is the New-Bilton Pit. Here the gravel is from 
6 to 10 feet in thickness, deepening towards the hill. The gravel is 
in some places very rudely and imperfectly stratified. The rounded 
quartzose pebbles lie, in one section at least, but not universally, with 
their long axes vertical. The surface soil is easily separable from 
the drift. The remarkable feature at New Bilton is the inequality 
of the level of the clay. It is Lias clay, and contains pebbles only 
just imbedded in its surface; but it is extraordinarily uneven, some 
ridges rising 5 or 6 feet in height and overhanging their bases, as in 
the accompanying sketch (fig. 2). The gravel lies in basins and in
