On the 3rd November 1871, Mr H. M. Stanley, a young newspaper correspondent, succeeded in finding Dr Livingstone. This was but the beginning of greater enterprises, for, catching the noble enthusiasm which characterised Livingstone, Stanley afterwards crossed the Dark Continent, and revealed the head-waters of the Congo. Again he plunged into Africa and succoured Emin Pasha, whose death was announced in the autumn of 1893. To Mr Stanley, Lord Granville, then Foreign Secretary, sent the present of a gold snuff-box set with diamonds, and the following letter: 'Sir--I have great satisfaction in conveying to you, by command of the Queen, Her Majesty's high appreciation of the prudence and zeal which you have displayed in opening a communication with Dr Livingstone, relieving Her Majesty from the anxiety which, in common with her subjects, she had felt in regard to the fate of that distinguished traveller. The Queen desires me to express her thanks for the service you have thus rendered, together with Her Majesty's congratulations on your having so successfully carried out the mission which you so fearlessly undertook.' The most notable events of the year 1873 were the death of the Emperor Napoleon III. in his exile at Chiselhurst, and the visit of the Shah of Persia, who was received by Her Majesty in state at Windsor. The Prince of Wales made almost a royal tour through India in 1875-76, and early in the following year witnessed the proclamation of the Queen as Empress of India. In 1886 the Queen opened the Colonial and Indian Exhibition at Kensington, the results of which, financially and otherwise, were highly satisfactory. On 21st June 1887, Her Majesty completed the fiftieth year of her reign, and the occasion was made one of rejoicing not only in Britain, but in all parts of our world-wide empire. In every town and village of the kingdom, by high and low, rich and poor, tribute was paid, in one way or other, to a reign which, above all others, has been distinguished for the splendour of its achievements in arts, science, and literature, as well as for its great commercial progress. One notable feature was the release of 23,307 prisoners in India. The Jubilee presents were exhibited in St James's Palace, and afterwards in Bethnal Green Museum, and attracted large crowds of sight-seers. The Jubilee celebrations were brought to a close by a naval review in the presence of the Queen at Spithead. The fleet assembled numbered 135 war-vessels, with 20,200 officers and men, and 500 guns.
