Having passed through the Old Channel, or rather the Channel of San Nicolas, between Cruz del Padre and the bank of the Cayos de Sel, the lowest of which furnish springs of fresh water, we again find the coast, from Punta de Icacos to Cabanas, free from danger. It affords, in the interval, the anchorage of Matanzas, Puerto Escondido, the Havannah and Mariel. Further on, westward of Bahia Honda, the possession of which might well tempt a maritime enemy of Spain, the chain of shoals recommences* (* They are here called Bajos de Santa Isabel y de los Colorados.) and extends without interruption as far as Cape San Antonio. From that cape to Punta de Piedras and Bahia de Cortez, the coast is almost precipitous, and does not afford soundings at any distance; but between Punta de Piedras and Cabo Cruz almost the whole southern part of Cuba is surrounded with shoals of which the isle of Pinos is but a portion not covered with water. These shoals are distinguished on the west by the name of Gardens (Jardines y Jardinillos); and on the east, by the names Cayo Breton, Cayos de las doce Leguas, and Bancos de Buena Esperanza. On all this southern line the coast is exempt from danger with the exception of that part which lies between the strait of Cochinos and the mouth of the Rio Guaurabo. These seas are very difficult to navigate. I had the opportunity of determining the position of several points in latitude and longitude during the passage from Batabano to Trinidad of Cuba and to Carthagena. It would seem that the resistance of the currents of the highlands of the island of Pines, and the remarkable out-stretching of Cabo Cruz, have at once favoured the accumulation of sand, and the labours of the coralline polypes which inhabit calm and shallow water. Along this extent of the southern coast a length of 145 leagues, only one-seventh affords entirely free access; namely that part between Cayo de Piedras and Cayo Blanco, a little to the east of Puerto Casilda. There are found anchorages often frequented by small barks; for example, the Surgidero del Batabano, Bahia de Xagua, and Puerto Casilda, or Trinidad de Cuba. Beyond this latter port, towards the mouth of the Rio Cauto and Cabo Cruz (behind the Cayos de doce Leguas), the coast, covered with lagoons, is not very accessible, and is almost entirely desert.
