That these two events are closely connected is probably 
the reason why we shall ultimately arrive at a correct 
conclusion relating to both; but, since there is no written 
testimony regarding either, there is no resource from whence 
any positive evidence can be derived, except the remains 
of the barrows and flint implements in the ancient villages 
of the Britons. 
I shall now confine my remarks to the flint implements 
and weapons which are found at Bridlington, and to some 
ancient fortified lines of intrenchment in the neighbourhood, 
which were constructed by the people who used these flint 
implements. 
Soon after I had commenced making a collection of these 
relics, I discovered that at some places white flint was used, 
at others gray, and sometimes both these coloured flints, by 
the same people, but that there was a marked difference in 
their form, as well as colour, and then that a distinct people 
had come among them, who used only red and black coloured 
flint; and these, with other reasons which will be apparent 
in the context, made me decide that I must divide them into 
classes. I found that those who used only white flint had 
two settlements, one on the cliff at Sewerby, and the other 
at Bempton, and that they manufactured their implements 
in such a rude, unskilful manner, that, although they are 
evidently intended for the same use as those made by other 
people, yet, if they were not specimens of the first attempts 
to manufacture flint into useful implements, no person would 
pick them up; but, as they form the first link of the chain of 
pre-historic evidence, their value in a museum is infinitely 
enhanced. But this observation must be understood to relate 
to the implements found at these two places only, as at other 
parts white flint is manufactured into beautiful forms. 
The gray flint implements have a peculiarly small, stunted 
form ; but those who made them had a very superior know-
