“Wait a minute, Elsa,” said Nordenholt. “It seems to me that all three of us have been cooped up indoors too much lately. Our nerves are getting on edge. Don’t deny it, Flint, in your case. You haven’t a leg to stand on. I heard you differing from one of your clerks to-day. We’d all be the better for fresh air now and again. One afternoon a week, after this, we’ll take a car out into the country. I can do my thinking there just as well as anywhere else; and Mr. Flint can drive to keep his mind off business. That’s settled. I told you before that amusement of some sort has to come into our routine, Flint; so you must just make up your mind to it. I can’t replace you if you collapse; so I can’t allow you to go on like this. You don’t look half the man you were six weeks ago.” I required no pressing, partly because I knew that Nordenholt was right in what he said. CHAPTER X The Death of the Leviathan In this narrative I must give some account of the happenings in the outer world; for, without this, the picture which I am attempting to draw would be distorted in its perspective. At this point, then, I shall begin to interleave the description of the Northern experiment with sketches of the state of affairs elsewhere; and later I shall return to the more connected form of my narrative. It may reasonably be asked how it comes about that I am able to give any account at all of occurrences in England immediately after the closing of the Nitrogen Area, since I have taken pains to show the complete severance of land-communications between the two sections of the country. I have already hinted that all connection between these regions was not abolished. Nordenholt feared an invasion of the Clyde Valley by some, at least, of the multitudes in the South as soon as they became famine-stricken. It was hardly to be expected that, with the knowledge of the food in the North which they had, they would remain quiescent when the pinch came; and it was essential to have warning of any hostile movements ere they actually gained strength enough to become dangerous. For this purpose, he had organised his Intelligence Department outside as well as within the Area. There was no difficulty in introducing his agents into any district. Night landings by parachute from airships, or even the daylight descents of an aeroplane on a misty day, were simple enough to arrange; and his spies could be picked up again at preconcerted times and places when their return was desired. In this way, there flowed into the Nitrogen Area a constant stream of information which enabled him to piece together a connected picture of the affairs outside our frontier. I have had access to the summaries of these documents; and it is upon this basis that I have built the next stage of my narrative. These reports, of course, were not published at the time.
