FOOTPRINTS OF VANISHED llACES IN CORNWALL. 273 



It should also be carefully noted, tliat many of these flints are by 

 no means small. Is is a common thing in the parishes of Kea, 

 Baldhu and Mithian to iind flints six inches long, and some found 

 in the subsoil and the surface of Penstrase Moors were actually a 

 foot in length.^^ Cornwall in prehistoric days contained in itself 

 flint enough for man to make his weapons from, so that we need 

 not imagine an extensive trade from the Blackdown hills in 

 Somersetshire to Cornwall, to provide the raw material for the 

 weapons used here in early times. 



The " Head of Eubble," also, which covers our Cornish 

 Raised Beaches, and which is often found in other positions, fi-e- 

 quently contains many flints, which are in the forms of pebbles, 

 nuclei, and fla^kes.^ Sir Joseph Prestwich has expressed his 

 opinion^^ that the Head is the i")lace where, most probably, the 

 weapons of Palfeolithic man will be discovered, and flint weapons 

 have actually been found in the Head, at Brighton, and San- 

 gatte.^'^ The Paised Beaches also contain shattered flints. 



It is also important to remember that flints, by no means of 

 small size, have been found in the stream-tin deposits of Corn- 

 wall. AVhatever differences of opinion may exist as to the 

 manner in which the stanniferous beds were formed, most geolo- 

 gists agree in assigning them to the Palteolithic period. Both 

 Professor J. A. Geikie^'^ and Mr. W. E. Ussher^' declare that they 

 are of this age, and Sir Joseph Prestwich^ maintains that our 

 stream-tin deposits belong to the closing portion of the Palaeolithic 

 period. The characteristics and distribution of these detrital tin 

 beds have been described by Mr. W. J. Henwood in his usual 

 masterly manner,''-' and the valuable account given of them by Mr. 



32. In clearing- the surface of a croft which had been taken in from the moors 

 in the neig-hbovirhood of Mithian, so many flints, many of them 6 inches long, -were 

 found on the surface of the ground, that the croft -was named " Flint-field.''
