Names were freely given, and the affair aroused the liveliest interest.

In vain Jack wrote letters explanatory of the occurrence. The papers would not insert them, so the lie went forth uncontradicted, and Maltravers was triumphant.

While Jack was chewing the cud of bitter reflection, he received a letter bearing the Calistoga postmark.

It was signed "Anonymous," and stated the following:

"If Mr. Harkaway wishes to meet Lord Maltravers, he can find him at the Geysers, in Northern California. Go to Fossville from Calistoga and you will find fresh instructions awaiting you, with Four-in-Hand Foss."

"Look at this," said Jack, handing the letter to Harvey.

Dick read it and replied:

"Queer! Who the deuce is Four-in-Hand Foss?"

"I'll find out, for I'll start for Calistoga to-day."

Mr. Mole entered at this juncture.
