SKY-WRITING MYSTERY.

WHY DID THE LETTERS CHANGE COLOUR? ; It,is estimated that nearly five millions of people witnessed the six demonstrations \ of J sky-writing, when two aeroplanes, piloted by Mr. Tait Cox and Mr Brady, wrote" ''Daily Mail" in flame-coloured smoke against the perfect blue sky over London. One aeroplane demonstrated above the Bast End of London and the Last India Docks, and then proceeded to South London as far as WalTington. The second' aeroplane skywrote over'Putney and Richmond, and' later gave an 1 exhibition at Wembley, which was ; seen as 1 far west as Southall and north at Watford. There was a mysterious effect in connection with the Wembley demonstration which even the sky-writer himself cannot account for. The letters as they were formed at a height of 12,000 feet changed their colouring. The original fiery tint varied as it was produced and gave the hundreds of thousands of onlookers a surprising exhibition of scarlet, pink, orange, and terra-cotta lettering. These strange variations may be due to some unusual atmospheric condition arising out of the heat-wave or to some subtle change in the chemical employed.

The public watching the demonstration noticed that smoke-writing persisted in the heavens for considerably longer than usual.
