194 RECENT ARCHAEOLOGICAL DISCOVERIES IN CORNWALL. 



(7). The marks, if many of them were not too horizontal, 

 might have been conjectured to have been caused by 

 stone or iron cannon-balls fired against the Grannel's 

 rocky shore by some ship during gun-practice. 



(8). The theory that they are natural, has not been put 

 forward, as far as I am aware, by anyone who has seen 

 them, but it would be desirable that geologists should 

 examine and report upon them. 



Any probable explanation will be welcome, and, if such be 

 offered, will be duly noted. 



A careful inspection of their appearance from the water and 

 from the opposite shore should be made. Photographs and 

 exact measurements also should be taken. These I have been 

 hindered from obtaining by the state of the tides, and by 

 inclement weather. 



To prevent any confusion or mistake, it must here be stated 

 that these slate-rock-cuttings are quite different and distinct 

 from the curious geological phenomena met with on the shores 

 of Fistral Bay, nearer Newquay, where perpendicular sand- 

 towers, as they are locally called, like hollow cylinders many feet 

 in height or depth, have been formed in the sand-stone above the 

 level of the present beach. 



(II). CINERARY URNS AND THEIR CONTENTS. 



Since the publication in 1872 of Nsenia Cornubise, Mr. 

 Borlase and others have discovered several additional specimens 

 of Cornish cinerary Urns. Amongst them those of Boscregan* 

 and Tregaseal.f The latter, 21 inches high and nearly 16 broad, 

 has been sometimes erroneously described (like one of the 

 former), as the largest found in the county; the remarkable 

 crossj of raised pottery on the bottom of it within was formed,

 significance of heathen crosses.
