In Chapter 3 of George Orwell's novel, Animal Farm, who did the animals admire the most? Why?

In Orwell's Animal Farm, the animals
begin to work the land and find it frustrating as the machinery and tools were designed
for men and not for animals. However, they have a great deal of respect for the pigs who
were extremely "clever" and seem to work out any kind of problem. (The pigs don't do any
work, but direct the other animals.) The horses understand mowing and raking better than
the humans ever had.

Boxer has the strength of three
horses, and works very hard. He wakes a half hour earlier than anyone else to get an
early start, and in the face of any challenge, his response
was,

I will work
harder!

Everyone except the
cat seems to assume some responsibility, even the hens and the ducks, based upon their
strength and capacity to understand.

If I had to decide
which animal is admired the most, it would be Boxer. His work ethic is admirable and his
service to the rest of the community never wavers. When more is required of him, he
tries harder.

(However, if I were to identify which animals
were the most powerful, it would be the pigs.)
