He left Petrograd yesterday for Helsingfors

"Feodor, I want you to go to the booking-office of the Finnish station at the departure of the train for Helsingfors at five-thirty. There you will meet a fair-haired young man who knows you by sight. He will say the word 'Anak,' and when he does, hand him this in secret. He will quite understand."

This order I carried out. I had not been at the crowded station five minutes when a young man, carrying a small handbag, elbowed his way through the excited crowd and uttered in an undertone the word "Anak." I greeted him, and surreptitiously handed him the little packet, for which he thanked me and disappeared on to the platform.
