INTRODUCTION 9 



A word may not be amiss relative to the frontispiece, 

 from a photograph of Egg Rock, taken from the Nahant 

 shore. This rocky islet is of ornithological interest, like 

 many others off our shores, doubtless having acquired its 

 name from being the nesting-site of several species of terns 

 or " Mackerel Gulls." The picture also shows well the 

 rugged character of much of the " North Shore."
