COLLECTING IN DIOBY, NOVA SCOTIA. 



BY LILLIAN DYER THOMPSON. 



While traveling through Nova Scotia and New Brunswick 

 last summer, we stayed for about six weeks at Digby, N. S. 

 Digby is about 200 miles northeast of Boston, and is situated 

 near the Bay of Fundy, opposite St. John, N. B. The town 

 is located on the southeast shore of the Annapolis Basin, — a 

 sheet of water about twenty miles long and ten miles wide. 

 This basin is connected with the Bay of Fundy by a channel 

 about three-fourths of a mile wide at its greatest width. This 

 channel, known as Digby Gap, is noted for its rapid tides, — 

 the rate of flow through the Gap being about eight miles an 

 hour. The tide fall at Digby is thirty feet. The shores of the 

 Basin are sandy, with the exception of the two rocky promen- 

 tories on each side of the Gap; the one which is nearest to Digby 

 being Point Prim. The town is on a small peninsula on either 

 side of which are two inlets of the Annapolis Basin, known as 

 the Racquet, on the west, and the Jacquet, on the east of Digby 

 proper. On the ebb tide these are almost dry, exposing long 

 mud flats. 



There is one island in the Basin, about opposite the Gap and 

 at the mouth of Bear River, called Bear island. From this a 

 long bar extends, called Bear Island Bar, which is covered to a 

 depth of about six feet at low water, and is covered with eel- 

 grass.
