curtain of hills of which the southern slope is covered with houses; this is the town of Trinidad, founded in 1514, by the governor Diego Velasquez, on account of the rich mines of gold which were said to have been discovered in the little valley of Rio Arimao.* (* This river flows towards the east into the Bahia de Xagua.) The streets of Trinidad have all a rapid descent: there, as in most parts of Spanish America, it is complained that the Couquistadores chose very injudiciously the sites for new towns.* (* It is questionable whether the town founded by Velasquez was not situated in the plain and nearer the ports of Casilda and Guaurabo. It has been suggested that the fear of the French, Portuguese and English freebooters led to the selection, even in inland places, of sites on the declivity of mountains, whence, as from a watch-tower, the approach of the enemy could be discerned; but it seems to me that these fears could have had no existence prior to the government of Hernando de Soto. The Havannah was sacked for the first time by French corsairs in 1539.) At the northern extremity is the church of Nuestra Senora de la Popa, a celebrated place of pilgrimage. This point I found to be 700 feet above the level of the sea; it commands a magnificent view of the ocean, the two ports (Puerto Casilda and Boca Guaurabo), a forest of palm-trees and the group of the lofty mountains of San Juan. We were received at the town of Trinidad with the kindest hospitality by Senor Munoz, the Superintendent of the Real Hacienda. I made observations during a great part of the night and found the latitude near the cathedral by the Spica Virginis, alpha of the Centaur, and beta of the Southern Cross, under circumstances not equally favourable, to be 21 degrees 48 minutes 20 seconds. My chronometric longitude was 82 degrees 21 minutes 7 seconds. I was informed at my second visit to the Havannah, in returning from Mexico, that this longitude was nearly identical with that obtained by the captain of a frigate, Don Jose del Rio, who had long resided on that spot; but that he marked the latitude of the town at 21 degrees 42 minutes 40 seconds. The Lieutenant-Governor (Teniente Governadore) of Trinidad, whose jurisdiction then extended to Villa Clara, Principe and Santo Espiritu, was nephew to the celebrated astronomer Don Antonio Ulloa. He gave us a grand entertainment, at which we met some French emigrants from San Domingo who had brought their talents and industry to Spanish America. The exportation of the sugar of Trinidad, by the registers of the custom-house, did not then exceed 4000 chests.
