But in all this wandering my boot-heel was wearing away, and it was a question of wearing into the packet of dispatches, or putting them in a place of security. I accordingly dug them out, and, hiding them in a convenient corner of the cupboard in my room, where they must soon have been discovered in case of a domiciliary visit, took the excavated boots out to throw them into the river, choosing the earliest darkness of the rainy evening of the same day. I knew that if the bootblack saw the excavated heel he would in all probability report the fact, and my arrest would follow. In my ignorance of the fact that the city was under martial law, and that without a pass no one could be in the streets after 8 P.M., I had waited till 9 to be screened by the darkness, and then, walking down the river on the dike, I slipped down to the water's edge by the path, and gently tossed the boots into the rapid current. Seeing the dangerous articles float away into the dark, I turned to go up the dike to the road running along the top of it, when, to my dismay, I heard a sentinel directly across the road challenge, saw the officer of the guard coming on his rounds, and heard his reply to the challenge. I hurried down the bank, hoping that I had not attracted attention, but feeling that in the contrary case I was in most imminent danger of arrest, and the thought of the dispatches left where they must be found in case of suspicion gave me a moment's anxiety. I hurried back along the water's edge till I judged that I was out of sight from the post, and then walked up on the dike and towards the hotel.
