56 THE NAUTILUS. 



short distance to the south stands Pacific Beach, facing both False 

 Bay and the ocean. Several miles to the north are the Torrey 

 Pines. Here stand, on the bluffs overlooking the sea, splendid spe- 

 cimens of Pinus torreyanus. At the base of these cliffs, in a wild 

 spot, a number of interesting finds were made.

 found at La Jolla. No dredging was done. Species found on the 

 surface of anemones are marked with a star.
