 COLLECTING AT BAR HARBOR 



THE beautiful coast of Maine is a particularly good field for 

 shore-collecting. The rocky coast harbors the boreal fauna 

 and flora which depend upon such physical conditions, and the 

 shores at Bar Harbor are typical of those found elsewhere in 

 northern New England. The rocks give shelter from the beating 

 surf, while life has exposure to the cold, pure waters of the arctic 

 current. Everywhere along the shore, rock pools are to be found. 

 These are perhaps the most fascinating of all spots to the col- 

 lector. They are veritable gardens of the sea, where species 

 flourish which naturally belong to deeper water, but which find 

 in such pools conditions suitable to their existence. 



At Bar Harbor one well-known and frequently visited rock 

 pool is found in Anemone Cave. Entering a field at Schooner 

 Head, one turns to the right and follows the rocky shore for two 

 or three hundred feet. It is difficult to take this short walk 

 without being constantly diverted and delayed by the various 

 attractions one meets, such as the tide-pools, the barnacles which 

 in places whiten the rocks, the periwinkles, the purpura shells, 

 and the curious algae ; but at last one arrives at a cavern under 

 an overhanging rock. Here is a large tide-pool which at first 

 sight displays only a beautiful scheme of color. It is carpeted 

 with a bright-pink alga, Hildeiibrandtla rosea, which incrusts the 

 basin of the pool. 



Interspersed with the pink are patches of a deep-red color, 

 having a velvety appearance, which are formed by another crus- 

 taceous alga, Petrocelis cruenta. The water of the pool is of crys-
