Everywhere he heard of El Dorado, but it was always receding farther and farther, until his men became so disheartened that he had to rouse them by saying that they would be shamed before their comrades if they gave up so easily. However, after reaching the mouth of the Caroni and getting specimens of gold ore, he had to return without doing more than locating the city of Manoa several hundred miles to the east of his farthest point. This was done in so exact a manner that the great lake of Parima, as large as the Caspian Sea, was retained upon the maps of South America down to the beginning of the present century. His ore was probably stream quartz, and in representing it as taken from the rock he probably reported what the Indians had told him. When, therefore, he said that the assay gave its value as £13,000 a ton, there is no reason to suppose a mistake or untruth, for pieces quite as valuable may still be picked up. His "Discoverie of Guiana" is such a mixture of close and accurate observation with the hearsay of the Indians, that it is difficult in some cases to separate truth from fiction. Yet, although historians have charged him with wilful lying, there can be no doubt of his good faith. It has been left to the present century to prove that gold-mines exist on the site of the fabled El Dorado, for it is there that the well-known Caratal diggings are situated. Ralegh asked the people of England to judge for themselves. He had spent much time and money, with no other object than to serve his queen and country. When they considered that it was the Spaniard's gold which endangered and disturbed all the nations of Europe, that "purchaseth intelligence, creepeth into councils and setteth bound loyalty at liberty," they would see the advantage of these provinces he had discovered. Guiana was a country that had never yet been sacked, turned, or wrought. The face of the earth had not been torn, nor the virtue and salt of the soil spent by manurance; the graves had not been opened for gold, the mines not touched with sledges, or the images pulled down from the temples. It was so easily defensible that it could be protected by two forts at the mouth of a river, and thus the whole empire be guarded. The country was already discovered, many nations won to Her Majesty's love and obedience, and those Spaniards who had laboured on the conquest were beaten, discouraged, and disgraced. If Her Majesty took up the enterprise, he doubted not that after the first or second year there would be a Contractation House for Guiana in London, with larger receipts than that for the Indies at Seville.
