He assembled a body of 190 volunteers, all valiant soldiers, and like himself, accustomed to all the chances of war, as well as acclimatised to the unhealthy effluvia of a marshy country, where fever, dysentery, and complaints of the liver were constantly present. Though the Isthmus of Darien is only sixty miles in width, it is divided into two parts by a chain of high mountains; at the foot of these the alluvial soil is marvellously fertile, and the vegetation far more luxuriant than any European can imagine. It consists of an inextricable mass of tropical plants, creepers, and ferns, among trees of gigantic size which completely hide the sun, a truly virgin forest, interspersed here and there with patches of stagnant water, where live multitudes of birds, insects, and animals, never disturbed by the foot of man. A warm, moist atmosphere exists here which exhausts the strength and speedily saps the energy of any man, even the most robust. With all these obstacles which Nature seemed to have rejoiced in placing in Balboa's path, there was yet another no less formidable, and this was the resistance which the savage inhabitants of this inhospitable shore would offer to his progress. Balboa set out without caring for the risk he ran in the event of the guides and native auxiliaries proving faithless; he was escorted by a thousand Indians as porters, and accompanied by a troop of those terrible bloodhounds which had acquired the taste for human flesh in Hispaniola. Of the tribes that he met with on his route, some fled into the mountains carrying their provisions with them, and others, taking advantage of the difficulties the land presented, tried to fight. Balboa marching in the midst of his men, never sparing himself, sharing in their privations and rousing their courage, which would have failed more than once, was able to inspire them with so much enthusiasm for the object that was before them, that after twenty-five days of marching and fighting, they could see from the top of a mountain that vast Pacific Ocean, of which, four days later, Balboa, his drawn sword in one hand and the banner of Castille in the other, took possession in the name of the King of Spain. The part of the Pacific Ocean which he had reached is situated to the east of Panama, and still bears the name of the Gulf of San Miguel, given to it by Balboa. The information he obtained from the neighbouring caciques, whom he subjugated by force of arms, and from whom he obtained a considerable booty, agreed in every particular with what he had heard before he set out.
