No such headline has ever been found in The Times at the period in question (the spring and summer of 1929), though one paragraph reads "An earthquake was felt yesterday between Illapel, to the north, and Talca, to the south, in Chile. No damage was done." (August 6, 1929). Source: The Quote... Unquote Newsletter (October, 2000) pp. 2-3.
A Discord of Trumpets (1956)
“Nobody can doubt that the entire range of applied science contributes to the very format of a newspaper. But the headline is a feature which began with the Napoleonic Wars. The headline is a primitive shout of rage, triumph, fear, or warning, and newspapers have thrived on wars ever since.”

Context: What people think about you is not supposed to matter much, so long as you yourself know where the truth lies; but I have found out, as have others who move in and out of newspaper headlines, that on occasion it can matter a good deal. For once you enter the world of headlines you learn there is not one truth but two: the one which you know from the facts; and the one which the public, or at any rate a highly imaginative part of the public, acquires by osmosis.

Context: If I fear anything, I fear the atmosphere of the war, the power which it gives to all the things I hate — the newspapers, the politicians, the puritans, the scoutmasters, the middle-aged merciless spinsters. I fear the way I might behave, if I were exposed to this atmosphere. I shrink from the duty of opposition. I am afraid I should be reduced to a chattering enraged monkey, screaming back hate at their hate.

"On the Cryptic and the Elliptic"
All Things Considered (1908)
Context: For fear of the newspapers politicians are dull, and at last they are too dull even for the newspapers. The speeches in our time are more careful and elaborate, because they are meant to be read, and not to be heard. And exactly because they are more careful and elaborate, they are not so likely to be worthy of a careful and elaborate report. They are not interesting enough. So the moral cowardice of modern politicians has, after all, some punishment attached to it by the silent anger of heaven. Precisely because our political speeches are meant to be reported, they are not worth reporting. Precisely because they are carefully designed to be read, nobody reads them.
