His esoteric project was the original project of Christopher Columbus, extended and modified.  Columbus had hoped to establish a communication between our quarter of the world and India across the great western ocean.  But he was stopped by an unexpected obstacle.  The American continent, stretching far north and far south into cold and inhospitable regions, presented what seemed an insurmountable barrier to his progress; and, in the same year in which he first set foot on that continent, Gama reached Malabar by doubling the Cape of Good Hope.  The consequence was that during two hundred years the trade of Europe with the remoter parts of Asia had been carried on by rounding the immense peninsula of Africa.  Paterson now revived the project of Columbus, and persuaded himself and others that it was possible to carry that project into effect in such a manner as to make his country the greatest emporium that had ever existed on our globe.

For this purpose it was necessary to occupy in America some spot which might be a resting place between Scotland and India.  It was true that almost every habitable part of America had already been seized by some European power.  Paterson, however, imagined that one province, the most important of all, had been overlooked by the short-sighted cupidity of vulgar politicians and vulgar traders.  The isthmus which joined the two great continents of the New World remained, according to him, unappropriated.  Great Spanish viceroyalties, he said, lay on the east and on the west; but the mountains and forests of Darien were abandoned to rude tribes which followed their own usages and obeyed their own princes.  He had been in that part of the world, in what character was not quite clear.  Some said that he had gone thither to convert the Indians, and some that he had gone thither to rob the Spaniards.  But, missionary or pirate, he had visited Darien, and had brought away none but delightful recollections.  The havens, he averred, were capacious and secure; the sea swarmed with turtle; the country was so mountainous that, within nine degrees of the equator, the climate was temperate; and yet the inequalities of the ground offered no impediment to the conveyance of goods.  Nothing would be easier than to construct roads along which a string of mules or a wheeled carriage might in the course of a single day pass from sea to sea.  The soil was, to the depth of several feet, a rich black mould, on which a profusion of valuable herbs and fruits grew spontaneously, and on which all the choicest productions of tropical regions might easily be raised by human industry and art; and yet the exuberant fertility of the earth had not tainted the purity of the air.  Considered merely as a place of residence, the isthmus was a paradise.  A colony placed there could not fail to prosper, even if it had no wealth except what was derived from agriculture.  But agriculture was a secondary object in the colonization of Darien.  Let but that precious neck of land
