Part 3

"Progress is making things... Newer!" CRUNCH! "Bigger!" CRUNCH! "Better!" CRUNCH!

And the creature chewed through a small tree like it was a carrot. Rabbit jumped out of the way as it fell. "You think this is making things Better?" said Rabbit. "You Monster!"

"I'm not a Monster," said the creature. "Monsters don't exist. Only very silly animals believe in Monsters." "OK, OK, OK, if you're not a Monster," said Woodpecker, "then WHAT WHAT WHAT are you?"

"You can call me... Castor Canadensis," said the creature. "Eh?" said Rabbit. "It is the scientific name for the North American Beaver," said Castor Canadensis.

"Why did you move our stream, Castor?" said Woodpecker. "I didn't move it," said Castor. "I'm just making it Bigger. And therefore Better. Progress!" "But..." said Bear, "how do you make a stream bigger?" "Engineering!" said Castor.

"You put an Engine in our stream?!" said Rabbit. "No, silly rabbit!" said Castor. "Engineering is the Science of Building Newer, Bigger, Better things." He waved at the deeper, wider stream. "Progress!" "What has that got to do with our missing trees?" said Bear. "Everything! Follow me, silly animals, and I'll show you."
