The work of exploration so well begun, so magnificently carried on, though so disastrously closed, began now to fall into other hands. Contemporaneously with the dwindling of the Portuguese into the background the English came to the front. It was then the Elizabethan period, that era of glorious memory, the dawn of Greater Britain. Bold mariners, like the world has never seen, sprang up on all sides, and made England the mistress of the seas. A spirit of commercial enterprise and adventurous daring was developed which nothing could dismay, nothing withstand. Before the close of that eventful period Drake had led his countrymen to the rich spoil of the Spanish Main, Raleigh had laid the foundation of English rule in North America, Baffin and Hudson had cleared the way for Arctic exploration, and Davis had not only started the series of heroic expeditions connected with the North-west Passage, but had led English ships to the Indian Seas. With these, however, we have nothing to do. Of more importance is it to us to note that Hawkins had made his first voyage to the West African Coast, and inaugurated that horrid traffic in human flesh and blood which has left such an indelible stain on British commerce. But it was not only the slave trade which drew the attention of English merchants to Africa. To them as to the Portuguese the Niger and Timbuktu were words to conjure with. Both were believed to be veritable mines of wealth. To the imagination of the time the one was pictured as flowing over golden sands, the other as almost paved with the precious metal. It was believed that the Senegal and the Gambia constituted the Niger mouths, and accordingly that to ascend either river would bring the traveller direct to the source of so much wealth. To accomplish this now became the dream of nations, so that it may well be said that the Niger and its fancied treasures were the magnet which drew men on to the exploration of the interior of the Dark Continent. It had been the mission of Portugal to draw a girdle round Africa; it was now to be the _rôle_ of Britain to take up the work and penetrate inland with more lasting results than had followed Portuguese embassies and missionary and commercial enterprises. The year 1618 saw the commencement of this noble work. A company was formed to explore the Gambia, with the object of reaching the rich region of the Niger. [Map: O. DAPPER. NIGRITARUM REGIO. 1671.] The honour of being Britain’s pioneer in African exploration fell to the lot of one Richard Thompson, described as being a man of spirit and enterprise. He left England in the _Catherine_, of 120 tons, with a cargo worth nearly £2000, and reached the Gambia towards the end of the year. Here he found the Portuguese still in power, ruling the nations with grinding tyranny, though rapidly sinking into the commercial and national apathy which has made them a byword in the nineteenth century.
