FEEDING. 287 



The Goby feeds more readily than the others. 

 Little atoms of meat dropped in soon attract his 

 attention. He turns up his eye, and watches them 

 as they slowly sink ; then, when he judges the proxi- 

 mity sufficient, he shoots ahead, opens his cavern- 

 ous mouth, and sucks in the morsel, and is in an 

 instant ready for the next. You may teach him thus 

 to come towards you when you approach. The Tom- 

 pot will not so feed ; but while the Goby is seizing 

 the morsels, watches him, bustles up, and drives him 

 away, but will not attempt to help himself.
