Winston dialled ‘back numbers’ on the telescreen and called for the appropriate issues of the Times , which slid out of the pneumatic tube after only a few minutes’ delay. The messages he had received referred to articles or news-items which for one reason or another it was thought necessary to alter, or, as the official phrase had it, to rectify. For example, it appeared from the Times of the seventeenth of March that Big Brother, in his speech of the previous day, had predicted that the South Indian front would remain quiet but that a Eurasian offensive would shortly be launched in North Africa. As it happened the Eurasian Higher Command had launched its offensive in South India and left North Africa alone. It was therefore necessary to rewrite a paragraph of Big Brother’s speech, in such a way as to make him predict the thing that had actually happened. Or again, the Times of the nineteenth of December had published the official forecasts of the output of various classes of consumption goods in the fourth quarter of 1983, which was also the sixth quarter of the Ninth Three-Year Plan. Today’s issue contained a statement of the actual output, from which it appeared that the forecasts were in every instance grossly wrong. Winston’s job was to rectify the original figures by making them agree with the later ones. As for the third message, it referred to a very simple error which could be set right in a couple of minutes. As short a time ago as February, the Ministry of Plenty had issued a promise (a ‘categorical pledge’ were the official words) that there would be no reduction of the chocolate ration during 1984. Actually, as Winston was aware, the chocolate ration was to be reduced from thirty grammes to twenty at the end of the present week. All that was needed was to substitute for the original promise a warning that it would probably be necessary to reduce the ration at some time in April.
