The New World now belonged to Spain. Perhaps the first purpose of the Spaniards was trade with the Indies, but their main object was that of gold, to be gained by slave labour. They could not themselves work in the tropics, even if they had had any desire for manual labour, which they had not. However, they began to introduce European plants and animals into Cuba and Hispaniola, a service which was of enormous value later to America, which possessed but a meagre range of staple food products and no beasts of burden or bovines. But gold--that was what they wanted. The shallow deposits of the island were soon exhausted, as were the poor willing Indians, killed off by forced labour. The barbarous treatment of the aborigines of the New World by the Spaniards--and the Portuguese--is one of the most dreadful blots on the history of America, indeed of the world. The easily gotten gold being exhausted, it was necessary to go farther afield. The Darien Settlement was transferred to Panama, the coasts of Yucatan and the Gulf of Mexico were explored by Cordova and Grijalva, from Cuba, and in 1519 the great Conquest of Mexico was entered upon by Cortes. So far the Spaniards had found little difficulty in subduing the Indians to their will, the inoffensive islanders, and Caribs, which latter became almost exterminated. The Indian folk of these islands were generally a simple and credible race, who at first looked upon the white man as a demi-god, but these simple children of the soil were treated with utmost callousness and barbarity. There is an example in the treatment of the natives of Watling Island in the Bahamas, which, as before remarked, was the first point in the New World trodden by Columbus. Of this land and its folk the explorer wrote to Ferdinand and Isabella: "These beautiful islands excel all other lands. The natives love their neighbours as themselves, their faces are always smiling, their conversation is the sweetest imaginable, and they are so gentle and affectionate that I swear to your Highness there is no better people in the world." But what was the lot of these folk? The Spaniards wanted further labour in the mines of Hispaniola, and to get these natives there they, trading on a characteristic love of the people for their ancestors and departed relatives, promised to convey them to the heavenly shores, where these were imagined as dwelling; and so, treacherously getting them on board the ships, they were taken away to the mines, where it is said 40,000 perished under starvation and the lash.
