"I tested the sand-glass by the bullet, and checked the log by a round
shot."

"Of what size was the shot?"

"One foot in diameter."

"Heavy enough?"

"It is an old round shot of our war hooker, La Casse de Par-Grand."

"Which was in the Armada?"

"Yes."

"And which carried six hundred soldiers, fifty sailors, and twenty-five
guns?"

"Shipwreck knows it."

"How did you compute the resistance of the water to the shot?"

"By means of a German scale."

"Have you taken into account the resistance of the rope supporting the
shot to the waves?"

"Yes."

"What was the result?"
