We will give but one proof more. On the last day of August, the day before the cable ceased to work, Valentia sent to Newfoundland two messages for the British Government, both signed by "the Military Secretary to the Commander-in-Chief, Horse Guards, London," and addressed--the first to General Trollope, Halifax, which said, "The Sixty-second regiment is not to return to England;" and the other to the General Officer commanding at Montreal, saying: "The Thirty-ninth regiment is not to return to England." The year before (1857) had witnessed the Sepoy Mutiny, which threatened the overthrow of the British Empire in India. The fighting was over, but the country was still agitated, and the Home Government in fear that the rebellion might be renewed, so that it continued to send forward fresh troops. It had sent out orders by mail for these two regiments to embark immediately for home, to be sent to India. But the mutiny being nearly suppressed, this was found not to be necessary, and the prompt countermanding of the order by telegraph saved the British Government, in the cost of transportation of troops, not less than fifty thousand pounds. The despatch to Halifax was received the same day that it was sent from London. The sending of this despatch, and its almost immediate reception, is attested by an official letter from the War Office in London. This array of proofs of what took place a quarter of a century ago, may seem superfluous now that experience has made despatches from the other side of the ocean one of the familiar things of our daily life. And yet at that date the achievement was so stupendous, and, as some thought, in its very nature so incredible, that men of the greatest intelligence could not be convinced. The late Mr. Charles O'Conor continued for years to quote the fact that some men believed that a message had actually passed across the Atlantic as the most amazing illustration of human credulity! Happily he lived to see and to appreciate to its full value this latest miracle of scientific discovery, applied by human genius and skill. CHAPTER XIII. CAST DOWN, BUT NOT IN DESPAIR.
