ON THE EROSION OF THE SEA-COASTS OF ENGLAND A^SD AVALES. 387 



2. At Rossall Point, where about ■120 feet has been washed awayshice the 1844-45 

 Kiirvey. 



The coast at both of these places is, generally speaking, low, witli sand and shingle 

 foreshore and no rocks. 



The amount of erosion varies so much that I have been unable to arrive at a satis- 

 factory average for each 6-incli sheet, but in attaclied list are given the maximum 

 amounts of erosion at each place, and on accompanying (5-inch sheets (21, 27, 28, 22, 

 :58, 37, 42, 58, 59, and 67) the present coast line is shown in red, where it differs 

 materially from the old, with some measurements of the extent of encroachment at 

 those points marked. The measurements in all cases are taken from rr^ traces, 

 except for Sheets 58 and 67, where the coast line was not replotted. 



I may add that the gain of land along this oast is. owing to the extensive 

 reclamation in the Kibble estuary and the construction of the Furness Railway, pro- 

 bably far greater tlian the loss occasioned by erosion. 'J'hfre is also a slight gain at 

 places near Barrow, due to slag from ironworks being tipped in the sea, forming 

 embankments.
