SEA-FISHERIES LABORATORY. 911 
Peereasowe cocklie bed. 
Two samples were collected from about the same 
place—that is, near the Wallasey end of the Leasowe 
embankment. There was a littie gutter running seaward 
just about the part of the sands where the samples were 
collected. Only one man was cockling, and he was 
washing the shell-fish in the water of this gutter. <A 
sample was therefore taken. It was very fresh. The 
sands at Leasowe are very clean, and there was no 
evidence of pollution,
