FOREST, LAKE, AND RIVER 



like fishes named, we have the cod-lings or squir- 

 rel-hakes, the three-bearded rocklings, both deep 

 water fishes, and the four-bearded rockling, which 

 is common in Massachusetts Bay. Of the three- 

 bearded rockling, Aristotle, in describing its habits, 

 states an interesting fact : It leads a solitary life, 

 is the only fish that has its heart in its belly, has 

 stones in its brain, like millstones in form, and is 

 the only fish which lies torpid in the warmest days 

 under the reign of the dog star, Sirius ; the other 

 fishes going into this torpid state in the wintriest 

 days. They bury themselves in the sand, and often 

 they make themselves invisible ; they wave the 

 little things in their mouths which fishermen call 

 little rods or little wands.
