"I'm afraid, sir, that nature has ordered it otherwise," he said.

"Have you finished?" asked his employer.

He looked at the still warm bowl of fluid suspiciously.

"It is all right, sir," said Jasper. "It is only noxious when it is boiling. That is why I keep the door locked."

"What is it?" asked John Minute, scowling down at the unoffending liquor.

"It is many things," said the other ruefully. "In point of fact, it is an experiment. The bowl contains one or two elements which will only mix with the others at a certain temperature, and as an experiment it is successful because I have kept the unmixable elements in suspension, though the liquid has gone cold."

"I hope you will enjoy your dinner, even though it has gone cold," grumbled John Minute.

"I didn't hear the bell, sir," said Jasper Cole. "I'm awfully sorry if I've kept you waiting."

They were the only two present in the big, black-looking dining room, and dinner was as usual a fairly silent meal. John Minute read the newspapers, particularly that portion of them which dealt with the latest fluctuations in the stock market.
