NOTE on CRUSTACEA. 



Large Crab at Withernsea. — A Crab weighing- over 5 lbs. was caug-ht 

 at Withernsea on 17th July. This is the larg-est specimen caught at 

 Withernsea within the memory of any of the inhabitants. — T. Sheppard, 

 Hull, 22nd July 1902. 



NOTE on TIDAL PHENOMENA. 



Big Waves on the Yorkshire Coast. — It appears that now and 

 again a wave of extraordinary volume occurs upon the Yorkshire coast, 

 immensely larger than any which go before or follow it. I have made 

 a note of several such waves in recent years. The most notorious example 

 is the wave which, on 13th October 1873, swept Mr. and Mrs. Paget off the 

 rocks just north of Filey Brigg. A tablet inserted in the cliff records that 

 'the spot in question is rarely covered at high tide, and at the time of the 

 accident it wanted but an hour and a half to low water.' 



One Sunday afternoon (again in October), about fifteen years ago, I was 

 standing with the Vicar of Saltburn on Bridlington Pier near the Victoria 

 Rooms. A gentleman came on to the pier and leant" upon the iron rail, 

 looking down on the water. Immediately a huge wave reared itself right 

 on to the place where he stood, and, but for the support of the rail, must 

 have swept him away. When the water ran off the pier, a number of live 

 Swimming Crabs {Portunus depurator)vjeve left behind, a striking' testimony 

 to the depth of the water hurled up. No wave before or after even cast 

 spray on this place during that tide. 



At the extreme point of Flamborough Head, near the isolated rock 

 called ' Green Stacks,' is a small ' creux ' (or roofless cave). Mr. G. W. 

 Lamplugh has told me that one day about twenty years ago, when he was 

 examining the boulder-clays which cap the chalk at this point, a wave of 

 great volume boiled up in this creux to such a height that he was in imminent 

 danger of being carried down by it. 



Some eight or nine years ago I saw it reported in a local paper that 

 a lady nearly lost her life in Thornwick Bay. She was sitting on the shore 

 reading, far away from the sea, when she found herself almost swept off* by 

 a wave. I myself witnessed an extraordinary wave in the same bav in 

 October 1887/ 



I have questioned fishermen about these extraordinary waves, and I find 

 their occurrence is quite recognised. They say they only occur when there 

 is a big swell on. The fact that never more than o>ie appears to occur on 

 each occasion is very singular, and seems to point to some rare coincidence. 

 The practical lesson seems to be that, if the sea is at all disturbed, it is best 

 to keep a lookout when wandering on the rocks or shore. — W. C. Hey, 

 West Ayton, Yorkshire, 5th September 1902.
