220 FISHES OF THE FIRTH OF FORTH. 



wards of ten thousand of these fish were taken by a foot 

 sean near Marazion. They frequently come so near the 

 shore as to enable persons to take them by hand. On Wed- 

 nesday evening another shoal appeared, when a number of, 

 men, women, and children, went into the water to catch 

 them, while others stood on the sand to see them throw the 

 fish on shore ; and by this means a vast quantity were ob- 

 tained. The young keep near the shore after the larger 

 fish have retired to deep water,"

 The flesh is considered by some as inferior food, by others, 

 as far superior to that of the mackerel ; it is firm, of good 

 flavour, and wholesome, and is in best season in March 

 and April. 



The large imbricated spinous plates forming the lateral 

 line, will distinguish this species from the rest of the Bri- 

 tish fishes.
