As a result of these elaborate precautions, it was as difficult to go in or out of Antwerp as it is popularly supposed to be for a millionaire to enter the kingdom of Heaven. Sentries were as thick as policemen in Piccadilly. You could not proceed a quarter of a mile along any road, in any direction, without being halted by a harsh "Qui vive?" and having the business end of a rifle turned in your direction. If your papers were not in order you were promptly turned back--or arrested as a suspicious character and taken before an officer for examination--though if you were sufficiently in the confidence of the military authorities to be given the password, you were usually permitted to pass without further question. It was some time before I lost the thrill of novelty and excitement produced by this halt-who-goes-there-advance-friend-and-give-the-countersign business. It was so exactly the sort of thing that, as a boy, I used to read about in books by George A. Henty that it seemed improbable and unreal. When we were motoring at night and a peremptory challenge would come from out the darkness and the lamps of the car would pick out the cloaked figure of the sentry as the spotlight picks out the figure of an actor on the stage, and I would lean forward and whisper the magic mot d'ordre, I always had the feeling that I was taking part in a play-which was not so very far from the truth, for, though I did not appreciate it at the time, we were all actors, more or less important, in the greatest drama ever staged. In the immediate vicinity of Antwerp the sentries were soldiers of the regular army and understood a sentry's duties, but in the outlying districts, particularly between Ostend and Ghent, the roads were patrolled by members of the Garde civique, all of whom seemed imbued with the idea that the safety of the nation depended upon their vigilance, which was a very commendable and proper attitude indeed. When I was challenged by a Garde civique I was always a little nervous, and wasted no time whatever in jamming on the brakes, because the poor fellows were nearly always excited and handled their rifles in a fashion which was far from being reassuring. More than once, while travelling in the outlying districts, we were challenged by civil guards who evidently had not been entrusted with the password, but who, when it was whispered to them, would nod their heads importantly and tell us to pass on. "The next sentry that we meet," I said to Roos on one of these occasions, "probably has no idea of the password. I'll bet you a box of cigars that I can give him any word that comes into my head and that he won't know the difference." As we rolled over the ancient drawbridge which gives admittance to sleepy Bruges, a bespectacled sentry, who looked as though he had suddenly been called from an accountant's desk to perform the duties of a soldier, held up his hand, palm outward, which is the signal to stop the world over.
