HABITS. 



The Chatham bars, dangerous, shifting sand shoals, guard the 

 entrance to a broad and placid bay at the elbow of Cape Cod which 

 is separated from the ocean by a narrow strip of beach many miles 

 long, known as Nauset Beach and made famous by Thoreau. Ex- 

 posed to the unbroken swell of the Atlantic Ocean these bars are 

 nearly always white with combing breakers and during easterly 

 storms are seething masses of foam and flying spray, beautiful to 

 look upon, but much dreaded by sailors, as they have proved to be 

 the graveyard of many a good ship. Only during the smoothest 

 weather do the fishermen dare to venture out across the bars to their 

 fishing grounds offshore. Many a time have I joined them on their 

 trips in their staunch catboats, picking our way safely among the 

 bars, leaving the gulls and terns behind us as the land faded in the 

 distance. When safely over the bars we could feel the gentle ground 

 swell of the ocean and begin to look for the gliding forms of the 

 shearwaters, the slender winged ocean wanderers. We were seldom 

 disappointed, for this is a famous summer resort for Tuhinares and 

 the birthplace of the, so called, species Puffinus horealis. Here on 

 October 11, 1880, Mr. Charles B. Cory (1881) obtained the type speci- 

 men from which he described the species.
