(2) The coast-station—their rondezvous—querry is it Norden? (You pass it 9.13)—there is a tidal creek up to it. High-water there on 25th, say 10.30 to 11 p.m. It cannot be Norddeich, which I find has a dredged-out low-water channel for the steamer, so tide “serves” would not apply.

(3) Your other clews (tugs, pilots, depths, railway, Esens, seven of something). Querry: Scheme of defence by land and sea for North Sea Coast?

Sea—7 islands, 7 channels between (counting West Ems), very small depths (what you said) in most of them. Tugs and pilots for patrol work behind islands, as I always said. Querry: Rondezvous is for inspecting channels?

Land—Look at railway (map in ulster pocket) running in a loop all round Friesland, a few miles from coast. Querry: To be used as line of communication for army corps. Troops could be quickly sent to any threatened point. Esens the base? It is in top centre of loop. Von Brooning dished us fairly over that at Bensersiel.

Chatham—D. was spying after our naval plans for war with Germany.

Von Brooning runs naval part over here.

Where does Burmer come in? Querry—you go to Bremen and find out about him?

I nodded stupidly over this document—so stupidly that I found myself wondering whether Burmer was a place or a person. Then I dozed, to wake with a violent start and find the paper on the floor. Panic-stricken, I hid it away, and went on deck, when I found we were close to Norddeich, running up to the bleakest of bleak jetties thrown out from the dyke-bound polders of the mainland. Böhme and I landed together, and he was at my elbow as I asked for a ticket for Amsterdam, and was given one as far as Rheine, a junction near the Dutch frontier. He was ensconced in an opposite corner to me in the railway carriage, looking like an Indian idol. “Where do you come in?” I pondered, dreamily. Too sleepy to talk, I could only blink at him, sitting bolt upright with my arms folded over my precious pocket-book. Finally, I gave up the struggle, buttoned my ulster tightly up, and turning my back upon him with an apology, lay down to sleep, the precious pocket nethermost. He was at liberty to rifle my bag if he chose, and I dare say he did. I cannot say, for from this point till Rheine, for the best part of four hours, that is, I had only two lucid intervals.

The first was at Emden, where we both had to change. Here, as we pushed our way down the crowded platform, Böhme, after being greeted respectfully by several persons, was at last buttonholed without means of escape by an obsequious gentleman, whose description is of no moment, but whose conversation is. It was about a canal; what canal I did not gather, though, from a name dropped, I afterwards identified it as one in course of construction as a feeder to the Ems. The point is that the subject was canals. At the moment it was seed dropped in unreceptive soil, but it germinated later. I passed on, mingling with the crowd, and was soon asleep again in another carriage where Böhme this time did not follow me.

The second occasion was at Leer, where I heard myself called by name, and woke to find him at the window. He had to change trains, and had come to say good-bye. “Don’t forget to go to Lloyd’s,” he grated in my ear. I expect it was a wan smile that I returned, for I was at a very low ebb, and my fortress looked sarcastically impregnable. But the sapper was free; “free” was my last conscious thought.
