LAW AND HORSFALL : FLINT IMPLEMENTS, 73 
of moorland which hes about four miles west of Rochdale, and 
thence trends north-west to the neig-hbourhood of Burnley. On 
several points of this ridge flints have been discovered, the most 
interesting- discovery however, was made on Middle Hill, near 
\¥hitworth. The opportunities for investigation on this hill were 
most favourable, owing to a considerable portion of its peaty covering- 
having been burnt off some ten or eleven years ago. Since that 
time atmospheric agents have lowered the loamy subsoil at least an 
inch, as is proved by little earth-pillars capped with stones, seen 
here and there on its western flank. On the southern portion of 
the hill flint chippings, flakes, small cores and worked fragments, 
were so alftmdantly scattered over the bare ground that no less 
than three hundred and fifty have been gathered. 
This contrasts strongly with the northern portion of the hill 
which, after a diligent search only yielded five flints. Many of 
the flints found at this place showed the bulb of concussion, others 
by secondary chippings have been fashioned into implements and 
weapons ; of the former about twelve may be mentioned which 
have been worked into a circular form by chipping^ round the edges. 
They vary in size from half an inch to one and a half inch. Of the 
latter class, a perfect arrow head of the barbed type, delicately 
chipped on both faces, and a well formed javelin's head or knife 
have been found. The last named is about two and a half inches 
in length and three quarters in breadth, and has every appearance 
of having been much used. 
About three per cent of the flints found on this hill appear to 
show the action of fire, their surfaces being traversed by small 
cracks bisecting each otJier at different angles. This leads to 
the inference that originally the flints were at different levels and 
are not all exactly of one age. Thus while those on the surface 
soil would be heated when it was burnt off, others buried in the 
underlying clay would be protected from such heat. At one or 
two places on the hill flints were seen sticking out of the loamy 
clay, while in other cases they were found capping little earth=
