This largest and handsomest of the diving birds, as it is the 

 most disagreeably voiced, comes down to our latitude in winter, 

 when its favorite inland lakes at the north begin to freeze 

 over and the fish to fail, and wanders about far from the haunts 

 of men along the seacoast or by the fresh waterways. Cau-

 States — for the majority nest farther north — it has exchanged its 

 rich, velvety black and white wedding garment for a more dingy 

 suit, in which the immature specimens are also dressed. With
