I found him sitting at a little table drawn close to the fire in a bare, dimly-lighted room. A lamp stood on the table, and he was peering at a crumpled scrap of paper and smoothing out its creases. So engrossed was he, indeed, in his scrutiny that it was some minutes before he raised his head and saw me waiting for his commands.

"Lieutenant von Altrock," he said, "you must ride to Raincy."

Raincy was only five miles distant, as the crow flies. Yes, but the French had made a sortie on the 21st, they had pushed back our lines, and they now held Ville Evrart and Maison Blanche between Raincy and Noisy-le-Grand. I should have to make a circuit; my five miles became ten. I did not like the prospect at all. I liked it still less when the Colonel added:

"You must be careful. More than one German soldier has of late been killed upon that road. There are francs-tireurs about. And you must reach Raincy."

It was a verbal message which he gave me, and I was to deliver it in person to the commandant of the battery at Raincy.

"There is a horse ready for you at the stables," said the Colonel, and with a nod he turned again to his scrap of paper. I saluted and walked to the door. As my hand was on the knob he called me back.

"What do you make of it?" he asked, holding the paper out to me. "It was picked out of the Marne in a sealed wine-bottle."

I took the paper, and saw that a single sentence was written upon it in a round and laborious hand with the words misspelt. The meaning of the sentence seemed simple enough. It was apparently a message from a M. Bonnet to his son in the Mobiles at Paris, and it stated that the big black cat had had five kittens.

"What do you make of it?" repeated the Colonel.
