of the introduction of metal. There is no sign of any gradual 
change taking place, as even the older tools made of gray 
flint are good, and were apparently in use at the time of the 
catastrophe, and the red ones were quite new : in fact, if any 
change of the kind was taking place, it was from gray flint 
implements to red ones ; but this does not account for both 
kinds having been left on two spots where the people had 
their workshops. The man who owned the red flint tools had 
certainly not bought them, or made them with the intention 
of not using them, and there must have been an impossibility 
for the people who were driven from their homes to have 
returned again to remove their valuable implements, or they 
would have done so. At the same time we perceive that 
those who drove them from their homes did not value the 
rude flint implements that the vanquished had left, or they 
would have appropriated them after they had expelled their 
owners. Every circumstance, therefore, leads me to suppose 
that the people who expelled them must have used metal 
weapons. 
Passing along the cliff towards Bridlington Qua} 7 , on a 
field on the north side of the new Alexandra Hotel, which 
was ploughed up this year (1866), I found various things that 
appear to have been used only for the purpose of agriculture ; 
and, from the positions of the tools, I considered they had 
been left in scattered buildings that were connected with the 
residence. They consist of what appear to be well-defined 
ploughshares of stone, with their coulters of flint, and stone 
wedges to fasten the framework of the ploughs together ; two 
stone hammers, a part of a machine of stone for grinding 
corn, hatchets of stone and flint, with various knives, spear- 
heads and sling-stones of both stone and flint. These flint 
implements are of the red and black colours, and the corn 
bruiser agrees in form with one found with the relics of the 
three families. In other instances I have found farming
