This was disconcerting, seeing that I had done nothing.

"Oh, but, sir," sounding that note of submissive expostulation which the tactful staff-officer contrives to introduce when he feels himself obliged reluctantly to express disapproval of superior military authority, "oughtn't we to do something? How would it be if I were to go down and see Grey, or one of them, and to talk to him like a father?"

"Well, perhaps it might be advisable to make a guarded suggestion to them on the subject. Give my compliments to ——" But he was gone.

He returned in about half an hour. "I've been down to the Foreign Office, sir, and as you might have expected, they haven't done a blooming thing. What those 'dips' think they're paid for always beats me! However, I've got them to promise to cable out to their ambassadors and consuls and bottle-washers in Scandinavia to keep their wits about them. I offered to draft the wires for them; but they seemed to think that they could do it themselves, and I daresay they'll manage all right now that I've told them exactly what they are to say. I really do not know that we can do anything more about it this evening," he added doubtfully, and with a worried, far-away look on his face. Good heavens, he was never going to think of something else! He took himself off, however, still evidently dissatisfied and communing with himself.

Next forenoon "Z" came into my room in a hurry. "I've been hearing about the caterpillars, sir," he exclaimed joyously.

"The caterpillars?"

"Oh, not crawly things like one finds in one's salad, sir. The ones the Admiralty are making[5]—armoured motor contrivances, with great big feet that will go across country and jump canals, and go bang through Boche trenches and barbed wire as if they weren't there. They'll be perfectly splendid—full of platoons and bombs and machine guns, and all the rest of it. I will say this for Winston and those mariners across Whitehall, when they get an idea they carry it out and do not bother whether the thing'll be any use or can be made at all—care no more for the Treasury than if it was so much dirt, and quite right too! Just what it is. But when they've got their caterpillars made, they won't know what to do with them any more than the Babes in the Wood. Then we'll collar them; but in the meantime I might be able to give them some hints, so, if you'll let me, I'll go across and——"

"Yes, yes; but just one moment. How about the poison?"

"The poison, sir? What poi—oh, that stuff. Didn't I tell you, sir? It isn't poison at all. You see, sir, it's this way. There are two forms of it. There's the white form, and that is poison, shocking poison; it's what the Fijians use when they want to pacify a busybody like Captain Cook who comes butting in where he isn't wanted. As a matter of fact there's uncommon little of it—they don't get a hundredweight in a generation. Then there's the red form, and that's what Johnnies have been dumping down 580 tons of at What's-its-name. It's quite innocuous, and is used for commercial purposes—tanning leather, or making spills, or something of that kind. Now may I go to the Ad——"

"But have you told all this to the Director-General?"
