The great diminution in the numbers of cockles and mussels 

 in Morecambe Bay and the estuary of the Duddon is attributed to 

 the depredations of sea-fowl, which have increased much since they 

 were protected by Act of Parliament. Mr. Durnford points out 

 that thirty years ago both birds and shell-fish were far, more abun- 

 dant than now; and he thinks it more likely that the abnormal 

 growth of the population of Furness and Barrow has upset the 

 whole balance of animal life.
