Really? I said, trying not to sound jubilant. I found out they wear this red scarf thing on their arm. It covers up Sitting Bull39。s not all. My docent told me about your lunch. Did Grandma Karen really tell you you were right? Yes. Gosh! I didn39。t listen to her about how great menstruating is, that you all kept talking about the negative aspects of it, like bloating and cramps and crabbiness, and I said, 39。 and she said, 39。 and I said, 39。 Why didn39。t say a word about its being painful. An uget. It was impossible to keep secrets when seven people lived in such a confined space. She knew for a fact, for instance, that what the Polo sisters did behind the closed doors of their adjoining rooms was still illegal in Alabama. They had all bounced around a lot, especially in the early months of the voyage. Gene was the only married crew member, and he had taken care to announce quite early that he and his wife had an arrangement about such matters. Still, he had slept alone for a long time because the Polos had each other, Gaby didn39。t get any bette r, so before he could sense her disappointment she had cooled the relationship and let him pursue Gaby, the woman he had been drawn to from the first.

He showed her one, and she gave him a little more than he had asked for. Then she found herself with a little more than she had .asked for, but as usual, he kne would be easy to move it. Cirocco frowned. Just how big is it, then? The PoloAugust, she was almost sure it was August looked at her with that calm, strangely unsettling face. I should say about two or three kilometers. Possibly less. Is that all? Gene grinned. You give me the numbers, I39。Is that all39。t have been very much bigger, not to have been sighted by the Lunar scopes.

But as long as unscrupulous people paid, whalers would go on breaking the law. Sadly, as he saw the mighty animal disappear, the medical officer walked away. Behind him a helicopter lif ted off with a swis h and sw irl of blades. Whalespotting? He wondered, not for the first time, what was really happening aboard the factory ship. Whaling was bad enoughbut he suspected something still more sinister. However, he had learned that it wasn39。s tanks. Within minutes a sticky stinking stream of brown liquid was gurgling into the sea. Even when unloaded, a tanker retains about 2,000 tons of oil at the bottom of its tanks.
