Hampden had brought him to the instrument room. In view of what he was asking of Lidiat, some explanation was necessary, but he put it into the narrowest possible form. It was framed not on persuasiveness but necessity.

"Salt is away, something has happened, and we have to move a week before we had calculated."

Lidiat nodded. He accepted the necessity as proved; explanation would have taken time. His training and occupation made him chary of encouraging two words when one would do, between midnight and the hour when the newspapers are "closed up" and the rotaries begin to move.

"I should like," continued Hampden, "in to-day's issue of every morning paper a leader, two six-inch items of news, one home one foreign, and a single column six-inch advertisement set in the middle of a full white page."

Lidiat had taken off his hat and overcoat and placed them neatly on a chair. It occurred to him as a fair omen that Providence had dealt kindly with him in not giving him any opportunity of changing his clothes. He now took out his watch and hung it on a projecting stud of the telephone box.

"Yes, and the minimum?" He did not think, as a lesser man with equal knowledge of Fleet Street might have done, that Hampden had gone mad. He knew that conventionally such a programme was impossible, but he had known of impossible things being done, and in any case he understood by the emphasis that this was what Hampden would have done under freer circumstances.

"That is what I leave to you. The paragraphs and comment at some length I shall look for. The provinces are out of the question, I suppose? The eight leading London dailies must be dealt with."

"You give me carte blanche, of course—financially?"

"Absolutely, absolutely. Guarantee everything to them. Let them arrange for special trains at all the termini. Let them take over all the garages, motor companies, and cab yards in London as going concerns for twelve hours. They will all be in it except The Tocsin and The Masses. We can deal with the distributing houses later. You see the three points? It is the patriotic thing to do at any cost; they can have anything they like to make up time; and it is absolutely essential."

"Yes," said Lidiat; "and the matter?"
