GLACIA.L DEPOSIIS OF THE TrNE VALLEy. 195 



bo caused by slipping due to the eroding action of water below 

 ground. 



In bringing this subject forward I, of course, do not intend 

 to throw any doubt on the Grlacial origin of true " Kettle-holes" 

 or of kames, and still less upon that of the sands and gravels 

 themselves. My intention is simply to show that some of the 

 tests commonly relied upon for the recognition of such products 

 of glaciation may be misleading, since they can be and are even 

 now sometimes imitated by another of Nature's many methods 

 of work. 



P.S. Subterranean erosion has recently been treated in several 

 papers, and the subject, if followed up, seems likely to yield 

 valuable results, I would especially refer to a paper by Mr. W. 

 Shone in the Quarterly Journal of the Geological Society, Yol. 

 XLVIII. (1892), p. 96, and to another by Mr. H. B. Woodward 

 in Natural Science, Vol. II. (1893), p. 124. 



Voracity of Cuttlefishes. — During a short stay at Cullercoats 

 in May, 1890, my attention was directed to a great number of 

 Haddocks among the fishermen's lines, which had been partially 

 eaten after they had been hooked. At first, I thought this had 

 been done by the Spiny Dogfish, but was told by a fisherman 

 that it was done by the " Ten-tails," the name given by fisher- 

 men to all kinds of Cuttlefishes. After the fishes are hooked 

 they are seized by the Cuttlefish, which winds its long tentacles 

 round the fish and tears off the flesh all along the back with its 

 parrot-like beak. The Cuttlefish holds on tenaciously till brought 

 alongside the boat, when it it beaten off, as the fishermen object 

 to handling them as they squirt a- jet of black fluid into their 

 faces when they attempt to land them. Probably this mischief 

 is done by Ommastrephes todarus, the commonest Cuttlefish on 

 our coast. — Richard Sbwse,
