"You know, all these are olive trees, you chaps," he said every five minutes. "I wonder if there are any olives growing on them?"

"Too early," said Archie. "It's the sardine season now."

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 regions," said Myra.

I thought for a moment. Superficially there is very little resemblance between an orange and a polar bear.

"Like polar bears," I said hopefully.

"I mean," luckily she went on, "polar bears do it for you in the polar regions. You really know you're there then. Give me the polar bears, I always say, and you can keep the seals and the walruses and the penguins. It's the hallmark."

"Right. I knew you meant something. In London," I went on, "it is raining. Looking out of my window I see a lamp-post (not in flower) beneath a low, grey sky. Here we see oranges against a blue sky a million miles deep. What a blend! Myra, let's go to a fancy-dress ball when we get back. You go as an orange and I'll go as a very blue, blue sky, and you shall lean against me."

"And we'll dance the tangerine," said Myra.
