"Oh, I tinker a chronometer once in a while," McPhearson answered. "I don't get them often, though."

"What on earth are they for?"

"You don't know?" The Scotchman raised his brows with surprise.

"Not really. I associate them vaguely with the sea and ships."

"So far, so good," granted the elder man.

"But the trouble is that's as far as I can go," Christopher said.

"Bless me!" ejaculated McPhearson.
