FIELD NOTES. 



FISHES. 



Record Nidd Trout. — A large Trout was found dead in the 

 grates of the Mill Race at the New York Mills near Patele}- 

 Bridge, on March nth. It weighed 5f lbs., and measured 

 2 feet 4 inches in length, and 12 inches in girth, and constitutes 

 a record for the river Nidd. Several anglers have at various 

 times had their tackle broken by a large Trout in the Nidd 

 dam, and no doubt this is the fish responsible for the damage. 

 An extra heavy rush of water probably carried the fish out of 

 the dam, and dashing it against the wall of the race or the grate,. 

 brought about its death. — R. Fortune. 



GEOLOGY. 



Boring' at Hull. — We are indebted to Mr. Somerscales for 

 the following ' particulars of Strata passed through bore at 

 Earles' Shipyard, Hull, 1890.' The position is on the west side 

 of the yard, and 550 feet from the river boundary : — Made 

 Ground, 14 feet ; Warp, 6 feet ; Clay, 12 feet ; Peat, 8 feet : 

 Yellow Clay, 5 feet ; Hard Clay, 11 feet ; Blue Clay, 3 feet ; 

 Marl, 3 feet ; Quicksand, 10 feet ; Boulder Clay, I4 feet ; 

 Gravel, 16 feet ; Chalk, +63 feet ; total, 165 feet. Doubtless 

 all between the Peat and the Chalk is of glacial age. — T. S. 



Boulder Clay in Flamborough Caves. — Last summer 

 whilst visiting the caves in North Sea Landing, Flamborough. 

 I noticed a small cave or fissure on the south side of the Ba.y. 

 in which Boulder Clay occurred, apparently in its original 

 position. This cave is on the beach level. 



A larger cave, on the north side of North Landing, which 

 has for its roof a flint band crowded with Hoi aster planus. 

 had in its upper portion, not only Boulder Clay, but bedded 

 sand and gravel. The glacial deposits seem to pass laterally 

 into ' grut ' or land-wash, such as occurs over the old pre- 

 glacial beach at Sewerby. This I believe to be in its original 

 position, and is not redistributed. If this be glacial deposit 

 171 situ, it follows that this cave, be it of land or marine origin, 

 is pre-glacial. The evidence seems to point to the fact that it 

 is a sea-cave, and therefore North Sea Landing is a bay dating 

 back to pre-glacial times. From this it would appear that 

 post-glacial erosion at this part of Flamborough has been 

 practically nil. — P. F. Kend.\ll, Leeds.
