"It was at Cannes that we saw the first oranges.
'That does it,' I said to Myra. 'We're really here. And look, there's a lemon tree. Give me the oranges and lemons and you can have all the palms and the cactuses and the olives.'
'Like polar bears in the arctic region,' said Myra.
I thought for a moment. Superficially there is very little resemblance between an orange and a polar bear.

"'I guess doodle-bugs is like South Polar bears,' he said.

Fact: "The seal is a particular favourite with [the polar bear], and he hunts this creature with skill and assiduity. When he perceives the seal basking upon a ledge of ice, he slips quietly into the water, and swims to leeward of his intended victim. He approaches by frequent short dives-so calculating his distance, that at the last he comes up close to the spot where the seal is lying. Should the victim attempt to escape, by rolling into the water, it falls into the bear's clutches: if, on the contrary, it lies still, the bear makes a powerful spring, seizes it on the ice, and then kills and devours it at his leisure."
