MORTIMER : OPENING OF THE TUMULUS " HOWE HILL," DUGGLEBY. 217 
flint. One side of this knife shows a portion of the rough drab- 
coloured skin of the block from which it has been struck ; four large 
flakes most skilfully removed from the side of the knife leave, with- 
out the usual finer chipping, an edge almost as sharp as a razor ; 
whilst its back has been formed by removing numerous small chips, 
mainly from the same side of the knife, leaving the back only about 
one-eighth of an inch in thickness. The other side of this knife has 
been left flat as struck from the core, with the exception of a short 
distance along the back where it is slightly chipped. There was also 
a large rejected core (pi. ix. fig. 1) of black flint, from which four large 
flakes had been struck from opposite sides, probably used as a 
hammer. About 250 pot-sherds were found, among which was one 
small bit of British ware ; a few fragments of Roman and Anglo- 
Saxon vessels ; and many portions of vessels of a more recent period, 
some glazed and some unglazed. There were also several pieces of 
gritstone, a few inches in diameter, all more or less reddened by the 
action of fire. In addition, the remains of the following animals 
were collected, viz. : — Bones and fifteen teeth of the horse;* bones 
and five teeth of the ox ; part of the under-jaw with teeth of the 
goat or sheep ; two under-jaws with teeth of a small dog or fox ; 
teeth and portions of the antler of the red deer. There was also 
three quarters of a human under-jaw, probably of a female ; several 
other pieces of human bone, most notably a portion of a very large 
femur, and another portion of a rather small femur, both of which 
had been deeply cut with a sharp instrument, probably belonging to 
some of the workmen engaged in the previous opening. These 
human bones indicate the removal of at least two adult bodies, most 
likely secondary Anglo-Saxon interments, which had been buried in 
the upper part of the mound. The great quantity of various kinds 
of pottery found in the upper and disturbed part of the mound is 
interesting and very unusual. It corresponds, in quantit) r and 
variety, with the pottery which the writer has obtained from three 
other mounds, one at Fimber, one at Wetwang, and one at Cowlam. 
But in each of these cases it was found either in, or connected with, 
* The teeth of this animal were found only in disturbed ground, at the 
summit of the mound, caused by secondary interments, and by the digging of 
the cross-formed trench in, most probably, Anglo-Saxon times.
