COLLECTING AT BAR HARBOR 
HE 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 alge; 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, Hildenbrandtia 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-
