BAENACLES. 



You cannot have wandered among the rocks on our 

 southern or western coasts, when the tide is out, without 

 having observed that their whole surface, up to a certain 

 level (often very precisely defined), is roughened with an 

 innumerable multitude of little brownish cones. If you 

 have ever thought it worth while to examine them with 

 more care, you have seen that, crowded as they are, so 

 thickly that frequently they crush each other out of their 

 proper form and proportions, they are all constructed on 

 the same model. Each cone is seen to be a little castle, 

 built up of stony plates that lean towards each other, but 

 which leave an orifice at the top. Within this opening, 

 provided the castle be tenanted by a living inhabitant, you 

 see two or three other pieces joined together in a peculiar 

 manner, which are capable of separating, but' which, when 

 brought together, effectually close up all ingress. 



Perhaps you have never pushed your investigations 

 farther than this, having a courteous respect for the feel-: 

 ings of the inmate, which has prevented your intruding on 

 a privacy so secluded. But I have been less considerate ; 

 many a time have I applied the steel chisel and hammer 

 to the solid rock, and having cut off some projecting piece 

 or angle, have transferred it, all covered with its stony 

 cones, to the interior of a glass tank of sea-water, for 

 more intimate acquaintance with the little builders at my 

 leisure.
