“Because in those days their tails moved side to side, like those on fish, in other words, their tails were straight up, thrashing the water from left to right, right to left. But spotting that they swam too fast, our Creator twisted their tails, and ever since they’ve been thrashing the waves up and down, at the expense of their speed.”

“Fine, Ned,” I said, then resurrected one of the Canadian’s expressions. “You expect us to fall for that?”

“Not too terribly,” Ned Land replied, “and no more than if I told you there are whales that are 300 feet long and weigh 1,000,000 pounds.”

“That’s indeed considerable,” I said. “But you must admit that certain cetaceans do grow to significant size, since they’re said to supply as much as 120 metric tons of oil.”

“That I’ve seen,” the Canadian said.

“I can easily believe it, Ned, just as I can believe that certain baleen whales equal 100 elephants in bulk. Imagine the impact of such a mass if it were launched at full speed!”

“Is it true,” Conseil asked, “that they can sink ships?”

“Ships? I doubt it,” I replied. “However, they say that in 1820, right in these southern seas, a baleen whale rushed at the Essex and pushed it backward at a speed of four meters per second. Its stern was flooded, and the Essex went down fast.”

Ned looked at me with a bantering expression.

“Speaking for myself,” he said, “I once got walloped by a whale’s tail—in my longboat, needless to say. My companions and I were launched to an altitude of six meters. But next to the professor’s whale, mine was just a baby.”
