But Etienne Rambert, after a moment's consideration, declined the suggestion.

"No: I would rather go by the slow train. If I take the express I should have to get out at Brives, and then I should be twelve or thirteen miles from Saint-Jaury, which is my destination; whereas the slow train stops at Verrières, where, by the way, I have already telegraphed to say I shall arrive to-morrow morning."

He walked a little way along the corridor, assuring himself that the various compartments were still quite empty, and then turned to the guard.

"Look here, my man," he said, "I am awfully tired, and I mean to get some sleep to-night; consequently I should like to be alone. Now where shall I be most quiet and undisturbed?"

The man understood. M. Etienne Rambert's enquiry about the place where he would be most quiet, was an implicit promise of a handsome tip if nobody did disturb him.

"If you like to settle yourself here, sir," the man answered, "you can draw down the blinds at once, and I dare say I shall be able to find room for any other passengers somewhere else."

"Good," said M. Rambert, moving towards the compartment indicated. "I will smoke a cigar until the train starts, and immediately afterwards I will settle down to sleep. By the way, my man, since you seem so obliging, I wish you would undertake to call me to-morrow morning in time for me to get out at Verrières. I am desperately sleepy and I am quite capable of not waking up."

The guard touched his cap.

"You can be perfectly easy, sir, and sleep without the least anxiety. I won't fail."

"Very well."
