25 THE SONG

CHAPTER 25 THE SONG Somewhere in the ocean, a whale was singing a sad song. It began with a high-pitched note. The note hung there for a while, and then descended, sliding down to a low rumble before swinging up a little higher and fading to silence. The song was repeated, but this time it came from a different direction and a different voice. Then it was repeated again, from somewhere else. Throughout that great, big ocean, whales were singing the same song, over and over. Roz scanned the area for whales, but she saw none. Sound can travel incredibly fast and far in water. The whales could have been anywhere. So the robot kept marching as the whales kept singing. Their sad song went like this. Whales are at home Across all the seas From warm waves of foam To where whole oceans freeze

But a danger emerges And it fills us with dread Southward it surges Leaving behind only dead Whales, we can't stay Through the blue we must ride There's no other way To survive the poison tide
