172 cole: DRIFFIELD AND MARKET WEIGHTON RAILWAY. 
ones, and on the top of Lair Hill the section exposed an unusual 
depth of surface soil, with several trenches 5 feet deep, in which were 
found horns and bones of deer. 
The chief cutting, 67 feet, is at Enthorpe, distant 10 miles from 
Driffield. Here a magnificent section of the Middle Chalk is obtained. 
I counted no less than 39 beds of tabular flints in a depth of about 
100 feet, allowing for the dip, most of which were persistent and very- 
marked. The beds of chalk were, as a rule, massive, not slaty, and 
I identify the zone as that called the barren zone" of Blake, only it 
must be quite twice the thickness which he gives. Very few fossils 
were found. A workman told me that he had hit upon a number of 
small shells adhering to the under surface of a large flint, but the 
specimen had not been preserved. An interesting section of a 
tumulus was exposed on the top of the hill, showing the encircling 
ditch, 5 feet deep, and 20 yards in diameter, so filled up with earthy 
matter that its existence would not have been suspected. The 
mound itself was scarcely visible, having been ploughed down. A 
whole cluster of tumuli, numbering from 16 to 20, may be seen at 
this point, which seems to have been a favourite burying place for 
the early Britons. 
Here too the railway cuts through an ancient entrenchment, 
running north and south for miles each way. A section of the 
partially filled ditch shows that it must have been seven or eight feet 
deep, between two ramparts. This entrenchment forms the boundary 
line of several parishes, e.g., AVarter and North Dalton, Lund and 
Goodmanliam ; but it is not always a boundary. Hence I conclude 
that this, and similar entrenchments, which are frequent on the 
Wolds, were more ancient than parishes, and were utilized, but not 
constructed, for marking their boundaries. It is noticeable that every 
parish between York and Bridlington is bounded by an old road, 
passing through Wetwang, which follows a line of entrenchments, 
still preserved on both sides of the monument erected to the late Sir 
Tatton Sykes. 
Another peculiar feature was observed at the Enthorpe cutting, 
not far from the tumulus first mentioned, but on t!:e opposite (south) 
side. A large hollow in the chalk rock was exposed, some 25 yards
