 them, as in the grayling ; and others, like the sheepshead, have 

 them in the back part of the mouth. Some have a soft

 are called tender-mouthed, while others have tough, bony, 

 or grisly linings that give them the name of leather-mouthed.

 examination of the subjects of his day's sport, the most inex- 

 perienced angler will soon learn to class the different species, 

 talk ichthyologically, and discuss scientifically of the form, 

 nature, and habits, of the objects of his pleasure by the 

 brook-side, the tenants of the lake, or of the ocean's depths.
