clusters, some have communication one with the other. 
They have a causeway running through the middle, and 
stone ramparts to protect them. At the eastern end is a 
lofty hill fort, called " Castle Hill." It is surrounded by 
terraces and platforms of levelled earth, one above the other, 
and with a fosse between ; it contains within its circuit 
several acres of ground. A little further on is a second 
lofty tumulus or barrow, called also "Castle Hill;" this has 
only a fosse. These British pits are lined with stone about 
three or four feet in depth, and were covered over with a 
roof of poles and turf. I could point you out a charcoal 
burner's hut in the woods close by, of the same pattern and 
build and material, no doubt, as those of older days. Water 
has been brought from a considerable distance, and flows 
under Castle Hill, within the entrenchments. It is wonder- 
ful that these footprints of British and Roman occupation 
should have survived the lapse of ages, and that so many 
centuries should have passed by, and the plough and the 
draining tool alike left them as they were, to teach us in the 
nineteenth century how our ancestors (no, not our ancestors, 
for I believe it is the Norse blood that predominates in this 
old North Humber kingdom), to show us how the former 
inhabitants of this Yorkshire of ours, were housed and 
dwelt. Singular that the camp of the invaders and the 
stronghold of the invaded should both in such near vicinity 
be here. 
One or two other footprints of Roman occupation I will 
just touch upon, as being familiar to you all in your own 
immediate neighbourhood. One is the use of the word 
" Corves." The measurement for coal at the pit's mouth, and 
the basket in which it comes up, still bear the Roman 
name of corvus, or basket, and testify that the Romans 
worked here the mines. Aldwark, also a Saxon word, 
speaks of an older work of pre-Saxon days ; and the next
