STOKIES ABOUT BIKDS. 251

'^ EYEEAL species of this bird are 

 .,,.;, described by naturalists. They 

 all, however, agree in many par- 

 ticulars, some of which I will describe. 

 All the species are very awkward and 

 unwieldy on land. The reader has often no- 

 ticed what bungling work a duick makes of 

 walking. He acts like a sailor who has just set 

 his feet on land, after a six months' voyage. 

 But the penguin greatly exceeds the duck in 

 awkwardness. Their body is larger and heav- 

 ier, and their legs shorter and clumsier. Their 

 wings are very short, too. They resemble the 

 fins of a fish, almost as much as they do the 

 wings of a bird in general. Penguins use their 

 wings in walking, to some extent, much in the 

 way that a man uses a setting oar to push a 

 boat along in shoal water.
